(D) WEATHER
Weather en route New London to area of operations varied from calm, mild days and cool nights, to raging seas, winds, and bitterly cold nights.
Weather in operation area was mild to warm, with choppy seas for most of duration. A period of about 72 hours in mid November produced ongoing storms with blinding winds, rains, fog, and heavy seas.
Weather en route BASE II from operating area was almost yachting weather along the Portguese and Spanish coasts. Shortly after passing Cape Finisterre as BARB entered out reaches of the Bay of Biscay temperatures dropped
with choppy seas and occasional rain squalls for duration of transit.
(E) NAVIGATIONAL AIDES
Lighthouse at Pointe de la Tour near Safi provided a aide to navigation in operating area.
Lighthouse at Cape Finisterre aided in navigation along the Spanish coast.
Lighthouses in the Firth of Clyde provided navigational aide en route to Rosneath.
(F) SOUND CONDITIONS AND SOUND GEAR
Sound conditions throughout patrol ranged from poor to okay. During the only torpedo attack of the patrol, sound had difficulty following
the surfaced U Boat target in the heavy seas.
Sound conditions were enemy were unknown but suspected likely as enemy U Boat did not appear aware
of BARB's presence until premature detonation of torpedoes.
(G) RADIO
Radio function for this patrol was normal.
(H) RADAR
SJ
SJ radar performance was excellent overall. Targets were typically detected at around 17000 yards.
SD
SD radar performance was sufficient overall. Typical detection range was 18000 yards. However,
a low flying TBF was not detected and in a case of mistaken identity, BARB was bombed.
(J) MINES
No mines were encountered on this patrol.
(K) ANTI-SUBMARINE COUNTERMEASURES AND TACTICS
No enemy ASW vessels were encountered. Just one enemy air patrol was encountered in operating area.
(L) MAJOR DAMAGE AND DEFECTS
BARB suffered minor damage when attacked by a USN TBF. All damage repaired at sea.
1. Rudder transmission
2. No.2 Periscope
3. Shattered glass fixtures-All compartments
4. Light bulbs-All compartments
5. Minor gland and piping leaks in Conning tower and control room.
6. Minor leaks in high pressure air lines.
(M) THERMAL LAYERS
No thermal layers were encountered on this patrol.
(N) SPECIAL OPERATIONS
BARB arrived in area a few days prior to scheduled November 8 landings and conducted
reconnoiter via periscope during daylight hours as close as 3000 yards off the beach.
Reports were sent to COMSUBLANT regarding tides, beach status, weather, and other vital
information on a
nightly basis.
BARB deployed six Army Scouts under LT DUCKWORTH via rubber boat approximately 4,000 yards
NNE of Point de la Tour near Safi at 2330 7 November. Operation went smoothly with the enemy unalerted.
Following this, BARB per orders, proceeded to position at the Safi landing beaches where provided guidance
via infrared signals. At dawn BARB submerged and observed the bombardment, exchange of gunfire with shore batteries,
carrier air strikes, and finally landing craft hitting the beaches. Per orders BARB cleared the area to provide
barrier patrol North-West of the landing area.
BARB was ordered to rendezvous with submarine U.S.S. Mullet off the Canary Islands. MULLET suffered critical breakdowns in
all four HOR engines during her patrol. Upon rendezvous on 14 November, via rubber boat the required parts and our best Chief Motor Machinist's Mate were transferred
to provide assistance. MULLET was able to get underway and per orders BARB proceeded independently, with her CMoMM stll aboard MULLET. Naturally, our Chief rejoined the crew
upon MULLET reaching port.

(T) REMARKS
A successful patrol in all assignments were completed to satisfaction. Great disappointment is felt at the failure to sink the enemy U-Boat
encountered on 11 November, due to torpedoes prematurely detonating and alerting target. Enemy ASW activity was surprisingly light throughout the patrol. The friendly fire incident of 17 November was quite disconcerting and not the only one to befall a boat of SUBRON 50 during operations in support of TORCH. Hopefully, such incidents are avoided in the future

PROLOGUE
Returned from First War Patrol, arrived BASE II Rosneath, Scotland and moored with tender USS BEAVER on 24 November 1942. Commenced standard refit. Twin 20 MM AA gun replaced single 20 MM. Three replacement torpedoes loaded along with provisions. Ready for sea 23 December 1942.
NARRATIVE
Departed BASE II, Rosneath Scotland for assigned patrol area in approaches West of the Bay of Biscay.
Proceeded down the West Coast of Ireland to assigned area at 15.5 knots by day and 10 knots during night time hours. Submerged to avoid aircraft on SD multiple times. While likely friendly, this was done to avoid friendly fire incidents. Arrived in area on 28 December 1942.
Conduct submerged patrol initially but heavy seas necessitated surfaced patrolling after 31 December. Over next 20 days no contacts were made, aside from one large flying boat believed to be German Luftwaffe. BARB was not detected.
Finally, at 1053 on 21 January, a SJ contact bearing 049 17600 yards was made. BARB headed for contact at flank speed to intercept.Vessel was soon tentatively identified as a surfaced U Boat, judging by course believed to be inbound to French coastal ports. GENERAL QUARTERS-TORPEDO was called and BARB submerged for attack at 1141. Upon submerging, BARB approached rigged for silent running at 100 feet, just below a thermal layer at 95 feet.
At 1213, BARB came to periscope depth and could make out the outline of a surfaced submarine on the horizon. Plot soon showed submarine on course 030 at 16 knots. BARB went back to 100 feet and continued approach. BARB rose to periscope depth for attack at 1235 with tubes ready to fire, torpedoes set to depth of 6 feet.
Upon raising of scope, boat was clearly identified as a Gato Class Fleet Submarine, believed to the SHAD en route home. To avoid confusion, BARB went to 150 feet and turned away , secured from GQ and remained submerged rest of the day, surfacing at 1900. No message regarding a submarine transiting our area was received.
BARB continued patrol in area, as approached thirty days and thus expiration of our time on station. Storms settled in during this time, making for a rough few days.
At 2118 on 24 January, BARB received a ULTRA ordering a search within 100 nautical miles of 44-50N 24-30W for damaged U-Boat and another en route to provided assistance. Set course for area West of current position. Course 258 at 18 knts.
En route to the search area, weather calmed but a strong chop remained in the seas. Upon arriving began search of area. Arrived in search area just after midnight on 27 January and began search. Submerged during daylight hours and searched, considering U Boat most likely would do this and did not want to expose BARB to submerged attack with her on surface. Surfaced at dark and continued search.
At 1805 SJ Contact was made, bearing 030 13250 yards. BARB submerged to close contact and went to GENERAL QUARTERS-TORPEDO.
After a long slow approach with no sound contact, came to periscope depth to find two large submarines, tentatively identified as U Boats Type 9, surfaced and alongside one another., with the one to starboard and farther away from BARB just slightly ahead of the closest one.
All bow tubes were made ready to fire and set to 6 feet depth. BARB closed to 1000 yards and at 2131 fired six MK 14 torpedoes.
Three torpedoes hit the closest U Boat, which quickly disappeared beneath the waves. Torpedo number four prematurely detonated just a few yards from second U Boat. This U-Boat was now underway, but given its proximity to three torpedo explosions appeared damaged. However, it was able to speed up enough to avoid the second and third torpedoes, which passed astern. Second torpedo reaching end of its run sometime later and the third detonating itself about 10 seconds after missing the target.
BARB was already swinging around and plotting to fire a stern shot at the now underway U Boat. Four torpedoes were soon fired, but just after firing U Boat disappeared, apparently submerged, all torpedoes missed.
BARB went to 150 feet, rigged for silent running, and collision. Sound never made contact with the U Boat again. BARB secured from GQ and remained submerged in area throughout the day, surfacing at 1900 hours.
Attempting to locate U boat again and wreckage but unable. Per orders, turned for home after midnight.
Passage home from 29 January- 3 February was uneventful. At 1001 on 3 February moored alongside USS BEAVER at BASE II, Rosneath, Scotland and terminated war patrol.

WEATHER
------------
Weather during transit and on station was typical for the area this time of area. Most days featured light to moderate fog and clouds, with seas always at a solid chop to heavy swells, with winds ranging from 10 knots to in excess of 30 knots. Several days of storms hindered operations in area at times.
Multiple large and moderate sized icebergs were observed in the area.
NAVIGATIONAL AIDES
--------------------------
Lighthouse on Jan Mayen Island provided navigational aide in assigned area.
ATTACK DATA
-----------------
No attacks were conducted on this patrol.
SOUND CONDITIONS AND SOUND GEAR
----------------------------------------------
Sound conditions were generally poor in assigned area due to heavy seas and temperatures.
Sound gear functioned properly but suffered in the poor sound environment.
RADAR
---------
SD
SD Radar performed well, with typical detection of aircraft at 14000 yards.
SJ
SJ function was adequate through first part of patrol. Around 20 March, SJ began to fail to detect surface targets. (had a accidental shell out to windows, so I reloaded a previous save after exiting game. Upon reload, SJ did not function rest of patrol. Possibly damaged?)
RADIO
--------
Radio function was normal during this patrol.
MINES
---------
No mines were encountered on this patrol.
ANTI-SUBMARINE COUNTERMEASURES AND TACTICS
-------------------------------------------------------------
No enemy ASW measures were encountered on this patrol.
One submerged enemy U Boat was located via sound, conducting a approach on BARB. Contact was made just after diving for patrol at dawn. Submarine was estimated 3000 yards and closing, likely nearing firing point. However, this is believed to be a chance encounter with a U-Boat operating or transiting through the area.
Several Allied aircraft and two destroyers attacked BARB in friendly fire incidents.
Allied ASV radar appeared to detect BARB long before they showed up on BARB's SD radar scope. This required BARB to submerged several times to avoid attack. Explosions indicating aerial depth charges and bombs were dropped. All of these friendly fire incidents involving aircraft took place at night.
Two Gleaves Class Destroyers, identities unknown depth charged BARB. BARB on the surface, encountered a DD South of Jan Mayen Island, NNE of Iceland. BARB's SJ radar did not detect the contact and thus contact likely already had BARB, who was on surface riding out a storm which had just cleared at time of contact, on her surface search radar.
Heavy sea state, thermal layers, and ocean temperatures helped to provide inadequate sound conditions for the hunters, thankfully. A second destroyer soon arrived on scene, indicating a ASW patrol.
BARB evaded the two DD's by rigging for silent running and depth charged, with evasion at test depth of 300 ft.
MAJOR DAMAGE AND DEFECTS
No damage occurred on this patrol.
Defects
SJ Radar Unit stopped functioning properly from 20 March to end of patrol.
Repairs conducted by USS BEAVER at BASE II, Rosneath.
THERMAL LAYERS
Thermal layers in area were quite shallowed as were recorded at 65-80 feet throughout area.
PERSONNEL
Crew performance was superb in spite of a challenging 30 plus days in area with heavy seas, bitterly cold temperatures, numerous "friendly fire" attacks, being stalked by a enemy U Boat and normal privations of patrol.
Eight men advanced in rating during this patrol, with one officer and six more being designated as "Qualified in Submarines".
HEALTH AND HABITABILITY
Health of crew and habitability of boat were overall satisfactory.
Rough seas did restrict meal preparations on some days and other challenges.

REMARKS
A challenging patrol given the weather conditions and difficulty of searching for enemy U-Boats, which was primary assignment in this area. Allied ASW attacks, particularly by air made operations a challenge.
Given experiences of this patrol, it is felt better that a friendly submarine not be assigned to these waters in the future.

War Patrol Report
USS Cisco SS-290
War Patrol ONE
12 September-18 October 1943
PROLOGUE
________
Arrived Brisbane, Australia 1 September 1943 from New London, CT via Balboa, Panama Canal Zone. After liberty for crew and voyage repairs, began daily training and work ups for patrol. Loaded 24 MK 14-1A torpedoes and provisions. Ready for sea 13 September 1943.
NARRATIVE
__________
Daily routine consisted of a trim dive at dawn, typically between 0630-0700 and a
second trim dive at dusk. Star sights were taken at appropriate times each day, navigators discretion.
SJ radar was secured during daylight with sweeps made ever half hour.
At night SJ sweeps were conducted every 10 minutes due to obvious reduced visibility.
With seven officers aboard, there were two officers on each watch, with the OOD on the bridge when surfaced, and in the conning
tower when submerged. AOOD stood watch in conning tower to monitor radar and sound data, dropping to control room
when a dive was called, unless at General Quarters.
Continuous sound sweeps were made when submerged. When surfaced, occasionally would stop engines to listen for contacts,
taking advantage of the hull mounted soundheads. When surfaced, SJ radar sweeps were made every half hour during daylight hours and every fifteen minutes during nightime hours.
Upon refueling at Darwin, proceeded to Area B4 in the South China Sea via Banda, Molucca, Celebes, and Sulu Seas, to the Mindoro Strait. Same course was followed home without a stop at Brisbane as have plenty of fuel for the return trip to Brisbane.

ANTI-SUBMARINE COUNTERMEASURES AND EVASION
___________________________________________
Enemy ASW was fairly standard. Convoys encountered had two escorts, one forward and one aft,
with each conducting sweeps to cover port and starboard sides.
94 depth charges were dropped during Depth Charge Attack No.1.
Evasion consisted of course, depth, and speed changes. Bursts of speed were made when enemy vessel was above
and dropping charges to get out from under.
Enemy appeared to have difficulties accurately tracking once CISCO reaches 500 ft.
MAJOR DAMAGE AND DEFECTS
________________________
No major damage or material defects occurred during this patrol.
Minor damage consisted of few broken light bulbs and glass fixtures due to
depth charge explosions.
SOUND GEAR AND SOUND CONDITIONS
_______________________________
Sound gear and performance were overall satisfactory.
RADAR
SJ Radar performance was over excellent with average detection range
of 20,000 yards.
SD Radar performance was normal with average detection at 12000 yards.
RADIO
______
Radio performance was normal.
MINES
______
Floating, loose, mines were encountered in Torres Strait en route to Darwin. They were
detonated by 20mm gunfire.

REMARKS
_______
A busy and productive patrol with one destroyer, and three merchant vessels sunk for a total of 25,695 tons. However, due to continuing torpedo malfunctions,
a valuable tanker was missed. Four torpedoes impacted tanker, all duds.
On the follow up attack, four torpedoes prematurely detonated en route to target.
Performance of the boat was excellent. Ability of the BALAO class
to routinely operate at depths in excess of 400 feet provides a real advantage during evasion as enemy active and passive sound gear seems to have much reduced effectiveness tracking submerged vessels at these depth.

ANTI-SUBMARINE COUNTERMEASURES AND EVASION
___________________________________________
DEPTH CHARGE ATTACK NO.1
-------------------------
Enemy DD's in Sibutu Pass detected CISCO on the surface
in excess of 10000 yards at night. Given there is no likely
way CISCO was visually spotted, it is concluded they were radar equipped.
Unable to outrun fleet type destroyers, CISCO submerged.
Enemy Destroyer's were first team and located CISCO
via active sonar at depth of 400 ft. The attack was fairly standard
for Japanese ASW. However, enemy sonar capabilities seemed
improved as they did not seem to lose solid contact with CISCO
until reached a depth of 550 ft.
Evasion consisted of depth and course changes along with "bursts" of speed
when enemy was above, preparing to drop depth charges.
Depth Charge Attack No.2
-------------------------
This depth charge attack conducted by the lone escort,
a Auxiliary Subchaser of about 1000 tons was ineffective.
After CISCO reached 500 ft, the enemy seemed to have difficulty
maintaining solid contact with CISCO. The choppy sea state
and thermal layers no doubt contributed to this as well.
Evasion consisted of depth and course changes along with "bursts" of speed
when enemy was above, preparing to drop depth charges.
DAMAGE AND DEFECTS
_________________________
Damage
------
Serious damage occurred courtesy of aircraft dropped
depth charges/bombs on 5 December. All damage repaired

were not detected due to flying at or below 1000 ft.
This includes the aircraft which was able to damage
CISCO on 5 December.
RADIO
______
Radio function was normal throughout
the patrol.
TORPEDO PERFORMANCE
____________________
Torpedo performance was much improved
over previous patrols. No premature detonations
occurred nor did any dud torpedoes occur.
SPECIAL MISSION
________________
Approximately six tons of supplies were stored aboard and
transported to Basay, Negros, Philippine Islands.
To make room for these supplies eight torpedoes (four forward, four aft)
were omitted on this patrol.
Mission was conducted according to plan upon sighting of security signals ashore.
Supplies were covertly sent ashore to friendly forces via rubber boat.
Special Mission successfully completed.
PERSONNEL
_________
Crew performance was overall excellent on this patrol.

REMARKS
________
A successful and somewhat eventful patrol. Areas patrolled upon
completion of special mission were surprisingly void of shipping.
Third assigned area did have a convoy pass through but it managed
to evade with course changes. However, if had more fuel and thus time
on station, it is likely would have located further shipping.
Torpedo performance in the lone torpedo attack of this patrol was excellent.
All four torpedoes which found their target detonated properly, sinking
a valuable 10,000 ton enemy tanker. The two misses were assured hits but as last two torpedoes fired,
the tanker was slowed by the four hits, causing a miss. Six torpedoes were fired as a precaution to ensure sinking the tanker as fuel status prevented any further pursuit in event of miss or malfunction.
SD radar's inability to detect contacts at lower altitudes continues
to be a liability on patrol. Damage sustained on 5 December by aircraft
bombs/depth charges were a direct result of SD failing to detect low flying
aircraft at distance to provide enough time to dive safely.

REMARKS
_________
A productive and busy patrol with six ships sunk for35,567 tons, in a area that since Fall of 1942 has been a "target rich" environment and remains so. With the sinking of two fuel laden southbound tankers, no doubt en route
to Rabaul to provide much needed aviation gasoline for aircraft based there, as our aerial offensive against the area continues. Depriving aircraft there of two tankers worth of fuel, sure made a "dent"in their operations.
Expectations of the new MK 18 electric torpedo were overall me, given a MK 18 was responsible. or the sinking of a 14280 ton Auxiliary Cruiser on this patrol. Obviously, the lack of a visible wake provides a advantage. However, the relatively slow speed and smaller warhead hampered overall effectiveness against other targets, as one large AK took two and sailed on,
while another hit with two MK 18, required follow up shots with MK 14 to ensure her sinking.
Ineffectiveness of enemy ASW on this patrol was quite surprising. While have seemed to deploy a heavier and more effective depth charge, the lack of vigor in their counterattacks was surprising, but appreciated.

AIKOKU MARU Class Auxiliary Cruiser sinking. Fired four MK 18. Target was making 18 knots. One MK 18 torpedo hit the stern, knocking out the prop and starting a fire. The fire burned on and off over a hour while the vessel flooding by the stern and eventually sunk. I had TheDarkWraith's fire damage mod enabled, pretty cool. :Kaleun_Salute:

ANTI-SUBMARINE COUNTERMEASURES AND EVASION
-----------------------------------------------------------------------
Enemy ASW was much improved over previous encounters,
with apparent improved sound equipment and depth charges.
Depth Charge Attack No.1
--------------------------------------------
1944-03-23
After Torpedo Attack No.1, the
escorting Momi Class Destroyer (now a DE) conducted a aggressive
and persistent attack, headed by a skilled Captain and crew.
Almost immediately after torpedo impact revealed CISCO's presence,
the escort pinged and located CISCO, rushing in. This prevented CISCO
from obtaining desired deep submerged prior to first salvo of depth charges,
forcing her to endure the barrage at "shallow" depth of 350 ft.
Attack continued for several hours, with CISCO reaching depth of 675 ft in order
to escape. Enemy remained in area throughout the day, with air patrols assisting. This
prevented CISCO operating in area as planned.
Depth Charge tally for this attack: 105
Evasion was fairly standard for CISCO was depth, course, speed changes,
and "bursts" of speed when enemy was above or nearby conducting depth charge run.
Depth of 675 ft in this instance seemed to cause enemy to lose sonar contact.
Enemy vessels are absolutely believed to now be equipped with
a more advanced and powerful depth charge.
Depth Charge Attack No.2
-----------------------------------
1944-03-30
Two contacts tracking east of Palau turned out to be a patrol of one DD and one
Subchaser. As APR-1 did not detect enemy radar signals during entire approach, it is believed enemy
had radar set switched off. Low visibility due to clouds and fog at night
prevented timely visual identification.
When Cisco was at 4500 yards roughly from lead vessel, APR-1 detected radar emissions
from the contacts bearing. Suddenly, gunfire erupted with shell splashes landing close
to CISCO. This prompted a quick dive to avoid.
Enemy pinging and attack began soon after. As a dedicated ASW patrol,
both vessels were obviously manned by skilled crews with best equipment, making evasion
a challenge. CISCO went to 675 ft once again to escape.
While enemy active sonar ceased, it appeared they maintained some type of hydrophone contact
as stayed quite close to CISCO dropping many charges. Most detonated well above, but
boat was shaken and some minor damage occurred from shockwaves at such depth.
Evasion consisted of course, speed, and depth changes, as well as submergence
to 675 ft.
Depth Charge tally for this attack was 171.
Airborne ASW
-------------------
Enemy aircraft in the Palau area were effective ASW patrols, forcing
multiple dives and bombing CISCO multiple times.
One low flying BETTY at dawn on 1 April, managed to fly in to just 6000 yards before detection,
dropping 3 depth charges/bombs along side CISCO as she submerged, causing heavy damage
and requiring return to port to terminate patrol.
Multiple enemy aircraft were equipped with radar and APR-1 typically detected
radar emissions before SD contact was made.
Some enemy aircraft appeared to turn radar on and off at intervals, likely
aware we may have radar detection equipment.

MINES
-------
1944/04/06 0227
10-46S 152-5E
Spotted floating mine in Jomard Pass,
detonated with 20mm gunfire.
RADAR
-------
SJ
SJ radar performance was again overall excellent. Typical detection
range on contacts was 28000-29000 yards. PPI scope again proved a real asset.
A curious exception to the performance was failure to detect a surfaced enemy submarine
(Torpedo Attack No.2). Check of equipment showed performing well. Low profile of enemy
boat appeared enough to evade SJ detection.
SD
SD performance was normal, with typical detection range around 13000 yards.
As always, low flying aircraft were not always detected. This lead
to a bombing at dawn on1 April that caused heavy damage to CISCO and
termination of patrol.
RADAR COUNTERMEASURES
--------------------------------------
APR-1 typically detected enemy radar emissions around
10-12 nautical miles, depending on conditions.
SOUND GEAR AND SOUND CONDITIONS
-------------------------------------------------
Performance of JP listening gear was overall excellent with contacts
detected at 15,000 plus yards, and precise tracking possible in most conditions
at 10000 yards or less.
Performance declined for duration of patrol after damaged by aircraft attack.
THERMAL LAYERS
--------------------------
One thermal layer was detected during Depth Charge Attack No.1 at 201 ft.
RADIO
--------
Radio performance was normal and satisfactory.
TORPEDO PERFORMANCE
---------------------------------
Performance of the new MK 23 torpedo was excellent with no known malfunctions.
These torpedoes sunk a tanker, submarine, and severely damaged at cargo vessel.
Using Contact only detonators without Magnetic Influence has proven
to drastically increase torpedo performance on last two patrols.

REMARKS
------------
A successful but challenging patrol cut short by unexpected heavy damage
from air attack. Ten downed aviators and crew rescued in lifeguard operations
are considered the highlight of this patrol, even with the sinking of
a tanker and enemy submarine, in addition to severely damaging a merchant
vessel.
CISCO's Balao Class design proved quite tough, standing up to operations
at extreme depths while being depth charged severely. Survival of the air attack
given the close proximity of the air dropped depth charges/bombs is a testament to stout construction.
Performance of SD radar versus low flying aircraft is ongoing issue of concern, which led to the heavy damage suffered on this patrol. As such, it is hoped the SD is improved in order to prevent such incidents in the future.

June 14
-----------
Patrol in area.
June 15
-----------
0000 Closed in to North End of San Bernadino Strait for close in patrol
per operation order. Enemy forces likely to sortie in response
to FORAGER (landings on Saipan) may exit via the strait.
0624 APR-1 detected radar emissions. Judged to be aircraft, submerged.
0625 Explosions above, not close as CISCO passed 71 ft.. Seems contact was a low ']
flying plane on pre dawn patrol. SD did not detect, not did lookouts.
Given apparent close proximity of contact, APR-1 saved the boat.
0630 Continued on for submerged patrol in North end of San Bernadino Strait, to cover per operation order in case of enemy fleet sortie via the strait in response to FORAGER.
0900 Weather turned foul. Overcast, light fog

12-58N 124-23E
Course 045 Speed 20 kts
CVx3,BBx2,CAx2,CLx2, DDx10+
1533 Due to tight screen in a "ring" by DD's, unable to get in close without
detection. Opted for long range shot, torpedoes
set to low power.
(Torpedo Attack No.1)
1538 Tubes 1,2,3,4,5,6 made ready to fire.
1541 Fired tubes 1,2,3,4,5,6 at CV (Believed to be TAIHO). Range 5701 yds.
Torpedoes fired through gap in screen on port side.
1544 Torpedo impact on a CA, amidships.
1545 Three torpedo impacts on TAIHO CV. Large fires visible
1545: One torpedo impact on BB, possible NAGATO class in second column!
31
1546 CV slowed visible list to port, three large fires burning.
Several secondary explosions.
1545: DD's rushing in, pinging. Rigged for depth charge and silent running.
27
1546 Torpedo impact! Torpedo heard hitting unknown vessel as CISCO passed
125 ft. Large explosions heard.
1547 DD above pinging. Splashes
1548 As CISCO passed 400 feet, DC explosions.
1549 Another DD above, more DC explosions,
close, boat shaken.
1552 Massive explosions audible from last bearing of CV TAIHO.
1554 Pinging, DD had solid contact on CISCO at 500 ft.
1555 Large pattern of depth charges, boat severely shaken. Damage reported.
Leaks in forward torpedo room.
1558 More explosions from last bearing of CV.
1601 CISCO at 525 ft. Two DD's made runs.
1602- Large patterns of depth charges, CISCO shaken, more
1603 damage reported. Leaks previously contained in forward torpedo
were now leaking again, causing flooding.
1605 Multiple large explosions from CV bearing followed
by "death noises". CV TAIHO believed sunk.
1610 Flooding controlled, water in compartment, bow slightly heavy, compensated with speed.
1611 A period of near constant pinging from multiple
DD's began. They appeared to be circling CISCO.
1617 Large DC pattern, boat shakes, damage reported. CISCO at 545 ft.
We were surprised by ability of enemy DD's to maintain contact in such
terrible sound conditions.
1618 More depth charges, close. Boat shaken, minor damage.
1620 More DC explosions, not close.
1621 Pinging stopped, lost contact with nearby DD's, believe were listening.
1623 Large explosions from area of CA hit during attack.
1630 Two DD's roared to life one ahead, one aft raced above CISCO
dropping large patterns of depth charges above and along the port side.
1631 Many DC explosions, several close, heavy damage reported.
1632 Flooding in control room, Engine rooms.
1633 Conning tower heavily damaged by DC exploding very close.
Executive Officer LCDR J.B. Butler severely injured (health fell to 15 percent)
At the helm, Chief Signalman G.C. Carter seriously injured (health went to 30 percent)
1634 Conning tower abandoned and sealed off due to damage and flooding.
1634 CISCO sinking, secured silent running, ordered speed to comepsante and full rise on planes
Damage Control Party assigned.
1635 More explosions. DC's, more damage reported in aft torpedo room.
1641 Managed to rise to 450 feet while battling flooding and other damage.
1644 More DC's, close.
1645 Pinging stopped, enemy dropping DC's around
appeared to have lost contact.
1654 Several DD's heard departing area high speed to join the task force
However, soon found out two were left behind to keep CISCO pinned down.
1702 CISCO at 410 feet , fighting to hold depth, battling
flooding. Suddenly DD roared above pinging,
dropping depth charges. One depth charge bounce off of the deck aft of conning
tower and exploded below CISCO, causing severe damage.
Hull damage went to 40 percent.
Every piece of equipment on boat had some level of damage.
Port prop shaft destroyed, aft battery damage at 94 percent.
Conning tower flooded and abandoned. Aft torpedo tubes destroyed.
Hydraulic pumps knocked out. Compressor destroyer. Stern dive planes transmission destroyed.Rudder transmission heavily damaged. No.1 and No.3 diesels disabled, could not repair at sea.With all damage, a battle surface was seriously considered, but some flooding had been contained thanks to valiant efforts of damage control party and some amount of depth control restored, but battery power was draining fast.
1730 After a few more runs, the enemy, for unknown reasons, gave up, two were heard
departing the area at high speed. However, wary one maybe had been left behind to listen.
CISCO continued to hold depth at 360 ft.
1840 Conning tower pumped out.
1930 Battery power nearly exhausted. Close to dark, surfaced and manned guns
in case needed, but no enemy was around. CISCO surfaced into flat calms seas and clear dusk skies.
Most likely reason for the effective enemy attack aside from first rate
destroyers and crews, was after going deep following the attack,
weather topside cleared providing ideal sound conditions for the enemy.
2000 CISCO was in shambles and ineffective. A message was sent to CTF-72
and set course for Manus Island to terminate patrol.
2030 Located large debris field, likely site where carrier TAIHO sunk.
June 16
----------
En route to Manus Island.
With two diesels knocked out along with port prop shaft surface speed was limited to 9.5 kts.
0655 Aircraft spotted bearing 044 8000 yards closing! Dive! Dive!
(Aircraft Contact No.4) SD did not detect aircraft.
0656 As CISCO passed 75 feet, several large explosions rocked the boat
causing severe damage. Notably heavy bulkhead hull damage in aft
torpedo room and flooding.
Hull damage on boat went to 75 percent.
All four stern torpedo tubes destroyed.
Rudder and Stern planes transmissions disabled, again.
Boat leveled at 100 feet. More explosions heard but aircraft did not have
CISCO.
Repairs completed and stayed at 80 feet until night fall.
2030 Surfaced, headed for Manus. All AA gunners would be on standby during daylight hours.

------------------------------------------
Enemy Anti-Submarine Countermeasures
--------------------------------------
British appear to have adapted convoy system as two large convoys
were encountered in area. Each convoy was well protected, the first
included the battleship sunk by torpedo and three destroyers.
Enemy "ASDIC" seemed adequate to detect and track the boat
up to around 100-140 meters. After reaching this depth the enemy
appeared to have trouble tracking. Enemy depth charge attacks were
persistent.
Enemy depth charges appeared to produce large and powerful explosions
but in nearly all cases they were set too shallow. This was likely due
to believing our U-Boat could not operate beyond certain depths
along with their ASDIC's trouble in tracking beyond certain depths.
Enemy merchant vessels encountered were not armed. However, these vessels displayed a penchant for attempting to ram our U-Boat as
this occurred, twice in two separate attacks. First, in a gunnery attack
on a 330 ton steam trawler, after several gun hits, the trawler turned as best speed to ram.
On the next occasion, after firing final torpedo from inside convoy,
a large merchant vessel of 5000 tons increased speed and turned towards
our U-Boat to ram. Increase to flank speed and application of rudder got us
out of danger but was challenging given the heavy sea state and close range
of vessel.
Torpedoes
------------
All fourteen torpedoes aboard were expended.
Eight torpedoes prematurely detonated
One torpedo missed target, alerted by premature detonations.
Five torpedoes hit target as aimed.
Remark
--------
Repeated torpedo failures prevented further success and waste of torpedoes.
A valuable 10500 ton enemy tanker was saved only by torpedo malfunctions.
However, crew and boat persevered in sinking a valuable enemy warship.

(Sadly, I was relieved of command upon return to port. In spite of success in three patrols, sinking of two tankers from neutral nations caused me to be removed and picked up by the Gestapo (Secret Police as it said) hmmm. This changed from OM, was not aware. Sinking neutral ships sailing with Allied ships is bound to happen, one was sunk by mistake when a torpedo missed target and hit the neutral)

Tracked a convoy all day to attack on surface at night. Ideal conditions. During approach, suddenly a storm blew in, seas grew heavy with winds, and rain, a light fog. Fortunately, at close range I could still see the ships, so took advantage and moved in for attack. Sunk one merchant. Attempted to set up on another but heavy seas made maneuvering into position difficult. Soon a destroyer was on scene, forcing us to dive. Rather dramatic attack.

12.55
U-47, responding to a contact report located a Large Eastbound convoy in Grid AL 82. A contact report was sent and convoy was shadowed. A report was received ordering immediate attack.
U-47 infiltrated the forward screen of convoy submerged and set up on center column with large tankers. At 14.32 fired two TI G7a torpedoes on a 8500 ton tanker range 1700 meters, fired one TI at large merchant at 900 meters and one at a large merchant at 1000 meters.
Torpedoes 1 and 2 hit the tanker. Tanker assumed not loaded with fuel as did not burn nor explode, but a noticeable list to starboard quickly developed. Torpedo 3 hit the large merchant but failed to explode...torpedo was a dud!
Torpedo 4 missed its intended target as its visible wake allowed vessel to slow enough to avoid, torpedo passed just ahead perhaps 2 meters. Per orders magnetic pistols were not active.
However, torpedo 4 would hit a 5000 ton merchant in next column which went up in a impressive fireworks show, most likely ammunition ship. At this point, enemy corvette was closing fast. A hard dive to 100 meters was ordered, rigging for silent routine and wasserbombe.
After twenty minutes and a few close wasserbombe, enemy lost contact once reached depth of 120 meters. After some time, eased to periscope depth.
Observed tanker sinking by the bow, but not burning. A oil slick and debris field visible from the ammunition ship sunk. A Hog Island Type freighter was passing astern, opened aft tube and fired from 1500 meters.
Torpedo missed target but impacted a Modern Passenger/Freighter 4500 tons, leaving a large visible hole admiships, vessel burning profusely. Enemy destroyer immediately closed out position. Resumed silent routine and went to 120 meters. A somewhat intense attack with several close wasserbombe occurred but after one hour and a depth of 160 meters, slipped away.
The modern passenger freighter sunk at 15.42
Surfaced several hours later after all clear and raced ahead, conducting torpedo reload.
Plans for a night surface attack inside the convoy were spoiled by the near full moon. Instead, opted for attack down moon from outside convoy flooded down to reduce visibility.
August 22, 1940
01.50 Targeted 9000 ton freighter in center column range 7500 meters. Fired tubes 1,2,3 TI G7a set to low power. Fired Tube No. 4 TI G7a at 4600 ton tanker range 6500 meters.
Two of three torpedoes hit freighter. Torpedo 4 hit the tanker. Large fires and explosions visible. Torpedo which missed target failed to hit anything and reached its end of run.
With decks awash U-47 turned to fire stern tube at outside column not just 3000 meters away. However, a enemy corvette suddenly emerged from the night firing, turned for down the throat shot.
A round from her forward gun found its mark, hitting U-47 in the stern, holing the sub. Stern tube disabled, compartment began to flood. Ordered boat to surface and manned guns. However, the flooding soon caused boat to sink to 8 meters, those on deck gun and AA gun aft were washed overboard. Boat maintained depth at 8 meters, with conning tower exposed.
A British destroyer arrived on scene at high speed and closed in, outrunning the corvette. While her main guns missed, her machine guns scored hits killing some on bridge. Continued attempts to blow tanks and surface briefly brought sub to 6 meters, but it soon sunk back to 8 meters.
Enemy destroyer rammed U-47, crippling the vessel, killing or knocking all remaining topside overboard. U-47 disappeared beneath the waves within seconds.

Not sure what this little bugger is, but every time we submerged it appeared. Spooky.

This one is kind of hard to see in a photo so i'll narrate.
we had just gutted a convoy of tankers and then went deep to evade.
"Deep" being relative in that we were in 275 foot waters.
we caught a break and found a thermal at approx 255 feet.
this DD and her cousins were pinging their a$$es off trying to find us.
THIS particular DD sailed right over the top of us, at about 1/2 knot more than our speed. it felt like it took an hour for her to completely pass us by.
And pass us by she did.:yeah::03:
https://i.ibb.co/sKKgfSZ/SH4-Img-2022-06-17-21-06-15-726.png

Nice. East China Sea is always a interesting area due to the shallow waters and heavy traffic. Esp when they do the slow roll above and cant tell if they actually detect you or just suspect or you expect them to drop and they do not...or they wait forever to drop lol.

100 difficulty...contacts off, external cam on for this one.
59 Days at Sea....nearly 40,000 tons sunk. First patrol in a Type VIIC
3 tankers, 2 merchants, one destroyer. One Tanker damaged.
5 of 6 sunk and one damage were from same convoy attacked October 25-26, 1940.
Earlier convoy intercept spoiled by onset of storms, lost in storms was unable to relocate. Took nearly a month to find a anything else to shoot at.
Then, in a epic running night surface attack than went into next day, plenty of targets.
In all this triumph of the first patrol....just 90 kilometers from Lorient...a aircraft scored a direct bomb hit, sinking U-95.

100 difficulty, map contacts off, external cams on for screenshots.
First War Patrol of U-95, Type VIIC U Boat.
Screenshots in previous post.
__________________________________________________ _____________
Departed Lorient at 0800 on 3 September 1940 for Grid AM 11 in Western approaches.
At 21.33 hours on 11 September, spotted a 4,200 ton merchant at 4000 meters ahead. Unusual to find a unescorted merchant in these waters but perhaps felt his high speed would protect him in a solo run.
At 22.06 fired Tube No.1 (G7e TII). Torpedo missed for unknown reasons.
Possibly ran deep in heavy seas.
At 22.35 Fired Tube No 2(G6e TII). Torpedo impact!
22.40 Vessel damaged but not sinking. Manned deck gun.
22.50 Sunk K-M-KF-M-K 9 (B) Merchant 4,200 tons
in Grid AL 32. Resumed patrol.
The next ten days were uneventful with yachting like weather in the area.
No contacts were made. At 21.53 on September 21, received report of Large Convoy in Grid AL 26 on Easterly Course at 6 knots. Plotted intercept and set course,with estimated interception time just after noon on September 22.
Spotted smoke at 12.31 bearing 340 20000+ meters. Submerged for sound check and upon pre surfacing observation, found heavy fog and overcast arrived in area with increased sea state. Surfaced and soon rains, 29 knot winds, and heavy seas settled in. Set course 090 at 7 knots to stay ahead of convoy until storms cleared.
For next three days maintained contact via sound checks but storms persisted preventing attack. Finally, at 22.00 on September 25, storms cleared, but had lost contact with convoy since last sound check at 21.30.
Searched area for 48 hours but unable to regain contact. Resumed normal patrol. Shifting to Grid AL on 3 October.
For next thirty days, U-95 searched area with no contacts, except for a unknown group of high speed vessels on October 16 , believed to be high speed transports and destroyers. Due to heavy seas and high speed was unable to make contact.
Finally, on October 25 at 15.39 made contact with a large eastbound convoy.
in Grid AL 35.Sent contact report and moved ahead shadowing until nightfall for surface attack.
At 19.15 moved in for attack on a moonless, but clear night with
no fog and light clouds. Seas were nearly flat calm with a 1 kt wind from the west.
After several attempts to work inside convoy from astern, each flank, and from ahead, decided it was not advised due to general decent visibility and tight formation of convoy. Opted to fire from outside the convoy, targeting
two large tankers and a large freighter in center column with bow tubes.
Moved in (attempted to flood down but the Type VIIC would not flood down as Type VIIB did, will have to adjust the settings in files) for attack, closing to 1800 meters off port column. Just as prepared to fire,
the lead freighter in port column apparently spotted U-95, as she increased speed and made a hard evasive turn to starboard, believing she was the target. The lead escort, a corvette made a "U turn" and headed for U-95's location. A destroyer about 5000 meters astern, the outside port escort, began closing at high speed.
In order to salvage the attack, increased speed to flank and set up on the Hog Island Type A Freighter second in line in outside column.
Closed to just 800 meters when the searchlight of the corvette ahead to port at about 1000 meters illuminated U-95. Fired TII G7e in tube 1 at the freighter and under heavy machine gun and deck gun fire, ordered a dive.
Enemy began pinging and closing when suddenly...torpedo impact was heard as we passed 22 meters. A series of secondary explosions followed the initial impact. Several rounds of pinging and wasserbombe were endured by as usual once hit 125 meters enemy seemed to lose contact.
Enemy freighter could be heard breaking up (freighter was burning, dead in water from a solid hit amidships, blew out engine spaces)
After about one hour, came to periscope depth astern at just 400 meters was a large 8500 ton tanker. Readied stern tube. Given short range a simple 180 bearing and 180 AOB with 0 kt speed was used. TII G7e was fired from stern tube, which hit the tanker. Tanker did not burn or explode as anticipated,
likely not loaded with fuel.
A large freighter was ahead, estimated 8000 tons. Not a solid solution but fired Tube No.2 TI G7e. Torpedo missed when freighter made hard evasive turn away from our periscope.
Completed turn and fired two G7e TII from tubes 3,4 at the tanker torpedoed minutes ago, tanker burned and began to sink, suffered a large explosion in engine compartments about two minutes after impact.
A enemy destroyer was closing in and ordered 150 meters. As passed 90 meters, wasserbombe exploded near stern, causing minor damage,
most serious of which were leaks and minor flooding in stern torpedo
and propulsion compartments. (See Damage Section below). Flooding quickly
contained. Many more wasserbombe were dropped but all were above with U-95 at 165 meters depth.
After some time, enemy was astern dropping wasserbombe on a false contact. U-95 went to 200 meters secured silent routine and reloaded torpedoes.
After reload complete, resumed silent routine and returned to 160 meters.
After two hours, came to periscope depth to find convoy moved on, except one destroyer and the Hog Island freighter torpedoed earlier. Freighter was dead in water, low, and burning at range 5000 meters bearing 094. Destroyer was about 3000 meters on opposite side searching, dropping occasional wasserbombe.
Turned bow towards the stricken freighter, opened tube No.2 and fired
the TI G7a on high power from 3500 meters. Torpedo hit the target, breaking its back. U-95 secured and surface, sped away. Freighter's two sections lingered for 10 minutes before sinking.
Now at flank speed, Tube No.3 was reloaded with the last reserve torpedo,
a G7e TII a, and U-95 raced to catch convoy. Dodging the rear escort, a destroyer, slipped inside the convoy from astern and spotted group of tankers, which had formed in the rear, with a destroyer just ahead keeping guard. Spotted a large 10,500 ton tanker and moved to port side at 4000 meters. After passing the giant tanker, turned to starboard for bow shot.
Due to size and priority of target, as well as evasive movements, fired four
torpedoes with two aimed at middle of target, one at aft stack, and one at fore mast, to cover the target well.
About 20 seconds after firing last torpedo, noticed the destroyer ahead of the tanker contingent turned hard to port, increased speed and began using his signal light. U-95 has been spotted. Began a turn but soon spotted a destroyer astern, we were boxed in! Turned toward the escort ahead to present minimal angle and ordered a dive when he opened fire/illuminated with searchlight. As the boat was submerging, two out of four torpedoes hit the tanker, both after. A large fire and explosion occurred after the second hit. Now under, rigged for silent routine and wasserbombe.
First destroyer and second laid on solid attack for twenty minutes before losing contact. At 01.25 the 10,500 ton tanker sunk (sunk by the stern) in Grid AL 35.
After evasion and coming to periscope depth it was now 04.00. A quarter moon had risen silhouetting the convoy ahead to our port at 10,000 or so meters. U-95 quietly surfaced and moved along side the starboard columns,
inside convoy dodging a destroyer in process. All bow torpedoes expended,
Tube No.5 had a TII G7e loaded with a TI G7a in reserve.
Attempted set up on several freighters but spoiled by course and speed changes and a destroyer, which did not spot but his routine patrol forced U-95 out of attack position. Around 05.30 while setting up for another attack, convoy zigged slightly throwing U-95 out of position, then a destroyer spotted the boat and rushed in. U-95 submerged to 140 meters.
The destroyer briefly hunted then rejoined convoy. This would seemed to be
the new tactic, force our dive, hunt, then move back to guard convoy.
After surfacing, decided to secure and move ahead for dawn (which was quickly approaching) submerged attack.
At 07.02 fired Tube No.6 G7e TII at 5000 ton merchant in outside starboard column. Torpedo hit, but was a dud. Alerted by the hit, vessel alerted and two destroyers arrived on scene. Pinging for several minutes but no
wasserbombe were dropped, the destroyers moved on.
Final torpedo was loaded, U-95 came to periscope depth at 11.00 to find a heavy overcast and moderate fog had set in, as well as choppy seas. Sound had convoy ahead. Surfaced and headed for bearing,
as could maneuver on surface under cover of the fog and perhaps find a target for final torpedo.
Located in the fog a large 6000 ton merchant, turned for attack at 13.50. However, merchant spotted U-95 as closed and fired with a stern mounted 3 inch gun! U-95 raced away and submerged.
Soon out of the fog, came a destroyer heading right for us. Turned a few degrees to port to line up for a "down the throat " shot on destroyer. Speed was set to Fast, with Pistol to magnetic in case choppy seas caused torpedo to run deeper.
At 700 meters, fired final torpedo from Tube No.5, TI G7a.
The C/D class destroyer, attempted to avoid by turning to port to allow torpedo pass alongside. Torpedo passed alongside the starboard but when just about amidships, it detonated, as it was close enough to trigger magnetic pistol. Destroyer erupted in a fireball and appeared to go out of control as it was moving at high speed and went into two circles before losing way, then heading off to the NorthEast profusely burning and listing.
In spite of fog, the large fires and smoke clouds remained visible at some distance. Soon another destroyer arrived in area, went to 100 meters to avoid. This destroyer never located U-95.
After some time, returned to periscope depth, no ships were visible except the smoke plume from the burning destroyer in the distance, estimated 3000-5000 meters. Closed to observe the burning vessel.
At 14.13, observed the destroyer sink rapidly by the bow. Soon after, spotted
in the fog what appeared t be a large tanker or merchant. While seas were choppy, they were calm enough for use of deck gun. Surfaced for gun action,
cautious to make sure target did not have a deck gun as the freighter encountered earlier did. This tanker was unarmed, and thus commenced firing from 1000 meters.
Loaded tanker quickly burned and exploded. Multiple waterline hits
sealed her fate. 8,300 ton tanker sunk in Grid AL 36. A destroyer was spotted emerging from the fog, U-95 submerged , went to silent routine,
destroyer dropped a few, but never came close to U-95.
Surfaced at 22.30 hours. All cleared. With fuel down to 25 percent and all torpedoes expended. Set course for Lorient for a uneventful passage.
Entered the Bay of Biscay on 2 November, 59th day of the patrol. That morning made two dives to avoid British aircraft, bombed once by twin engine. In the afternoon, just 90 KM from Lorient, another twin engine aircraft appeared. Ordered AA gun manned and set the plane on fire. However, it's bomb found its mark, hitting U-95 just forward of conning tower. Most topside were killed, a few injured. Boat quickly began to sink, in spite of best efforts, massive flooding throughout all forward compartments and conning tower/control room. As U-95 slide under, the aircraft crashed into the water.
U-95 sank to the bottom and crashed at 110 meters, unable to surface, she was doomed. ( I rarely every joust with aircraft, habit from TMO. I was not aware dark waters aircraft, esp in 1940 were deadly . Will not repeat this mistake. Killed on first patrol, which started out great)
Love the effects of this mod...the oil slick after the sub sunk which was above my sinking location and moved if sub moved. The deck hatch which closes when dive, opens when surface.
Final Total for patrol:
Two merchants, three tankers, one destroyer sunk.
39,657 tons.

North Atlantic Convoy Lanes.
U-409 Type VIIC
100 difficulty map contacts off, cam on
Probably my best submerged attack on convoy in Dark Waters so far.
Managed to get inside convoy submerged. One torpedo, one ship. Fired four TII G7e bow torpedoes, sunk two ships outright, another followed.
Fourth, the ship slowed and torpedo hit the bow of Type A Hog Island Freighter, nearly blowing it off. Switched to stern tube to hit a ship close crossing stern. While plotting its speed, raised scope for next mark when could hear the sounds of ship very close, quickly scanned around with scope to see the mangled bow of the freighter filling the lens(!) Seems although severely damaged, she decided to come over to ram our scope. Ordered
down scope and emergency dive to 25 meters but it was too late.
U Boat shook, groaned, noises of steel colliding, then damage reports piled in as lights flicked on and off. The freighter had rammed our boat , which pushed us for a time from 12 meters to 20.
The ramming caused severely damage to propulsion room and control room bulkhead, with heavy flooding, blew ballast and surfaced at full speed, hoping to survive long enough to pump water and try for some escape.
Also, with one torpedo left and the vessel that just rammed us astern...fired stern tube from 400 meters, hitting the Hog Island Type aim amidships, blowing large visible hull in the vessel...revenge for the ramming.
As raced through the convoy on surface, fighting flooding and heavy seas, took gunfire. Nothing large hit but some machine gun fire from a nearby merchant hit us. Used AA guns to sweep the deck of the freighter from 900 meters. Must have killed gunners as gunfire ceased.
Progress was made during this time, as damage control pumped some water from control room, but propulsion room was full and weighing down the boat, which was riding at 6-7 meters in water.
A destroyer was spotted astern, jogging in and out among the columns trying to catch the U boat.
However, at 1306, in spite of some water pumped, U Boat sunk from the surface . Blew ballast, tried everything could, including blowing ballast repeatedly until tanks dry, but unable to surface. Descent was slowed at 200 meters by water being pumped from control room but propulsion room remained flooded and unable to stop the descent. Passed 260 meters...off the gauge and a few minutes later, hit crush depth.
Few shots, happened fast so was not able to get the moment I was rammed in screenshot, just immediate aftermath.

Screen shot of a Soviet frigate whom i torpedoed.
she is sunk and i received credit however when i was re-traversing the area this shocked the H out of me.
so, she took enough damage for SH4 to classify her as sunk and yet she is as much on the surface as she would be if she was still patrolling.
interesting damage model to say the least.:haha:

_____________________________________________
WEATHER
Weather in area was mostly clear and calm, with
a few days of high winds and light fog. Weather in transit
to and from base was almosy yachting weather majority of time.
NAVIGATIONAL AIDES
No navigational aides were spotted in area, aside
from the atolls themselves. Blackout conditions
appeared to be observed on the islands.
MINES
No mines were encountered on this patrol.
RADIO
Radio function was normal throughout the patrol.
RADAR
SD radar appeared to function correctly. However,
no aircraft were encountered on this patrol.
SOUND GEAR AND CONDITIONS
Sound gear functioned well overall,
detecting contacts in excess of 10,000 yards
in some cases.
Sound conditions in area were overall satsisfactory.
THERMAL LAYERS
No thermal layers were
detected.
ANTISUBMARINE COUNTERMEASURES AND EVASION
Assigned area was patrolled by one or more Destroyers
and several small patrol craft or auxiliary type Subchasers.
Enemy destroyer encountered was equipped with active sonar
as evidenced by it's pinging. However, aside from initial
attack once TRITON was at 250 ft, enemy appeared
to have lost contact.
Evasion was conducted by rigging for silent running
and evading at test depth of 250 ft.
MAJOR DAMAGE AND DEFECTS
Damage
All damage repaired at sea unless indicated
otherwise.
1. Forward Batteries
Depth charge attack of 20 December 1941 caused serious damage
to Forward Batteries. One, possibly two depth charges exploded
forward to starboard at estimated 50-100 feet distance.
Upon completion of repairs, it was found forward batteries could not gain
full charge, with just seventeen percent of their capacity. This limited
submerged endurance and performance, with aft batteries carrying the load.
After several days, forward batteries began to fail, with recharge
capacity falling to just thireen percent.
2. Leaks-Forward Torpedo Room.

Defects
None
PERSONNEL
Crew performance throughout patrol was excellent with
strong morale in spite of trying circumstances.
HEALTH AND HABITABILITY
Conditions onboard were overall comfortable
with climate maintained and well prepared meals.
Relatively short duration of patrol also helped
maintain conditions onboard.

REMARKS
A key enemy outpost, there was a surprising lack of merchant shipping encountered
in the Marshall Islands, in the Kwajalein area in particular. Perhaps further
time spent in area would have located enemy shipping.
Lack of enemy air patrols was also surprising. With war now declared,
it is likely enemy will reinforce the islands.
Torpedo performance was concerning as at least
four out of six fired out of six fired prematurely detonating.
Two of these explosions were confirmed visually when
torpedoes detonated in succession just 20-30 yards from
the destroyer they were on solid track to impact. These malfunctions
cost the sinking of one, perhaps two enemy warships.

Since I've started to play I have found that I love SH4, though I do admit it has some... quirks. Things like escorts running around like chickens with their heads cut off and not actually trying to protect their flock allowing me to just stay at periscope depth and pick ships off. Also the utter plethora of aircraft flying around and running into three Task Forces of two to three Hiryu class, a Shokaku, and various escort carriers, cruisers and the like. Hell supposedly I got the MOH on first patrol of one career attempt, though the medal was utterly wrong. All settings except manual TDC and map were clicked so realism was 75 percent.

So I looked at mods available and fell in love with the Idea of Trigger Maru Overhauled and applaud Decimus and all who helped them.
So I am getting used to TMO and I love it though I have a much harder time hitting a target I admit. Last night I managed to get past the escorts and while I never saw the merchies in the pouring rain I did see a Mogami Class Heavy Cruiser. Managed to sink her after using all 8 torps (not proud of that) to do so then went deep. Got a hell of a shellacking and spent the next few real life hours sneaking away. Tonight I have to finish my patrol with no working tubes and just deck gun any single merchies I manage to find. I've managed to get two so far, but still have over a day left of being on station before I should get a complete... then I am heading home without giving a status report. Feel kinda useless as a vulnerable "gunboat".
I do admit I find it funny that I got a radio report of me delivering ammo and getting spare parts, torps, and refugees from Corregidor. Took me a bit to work out that it wasn't new instructions, just a message using a random sub and happened to use the one I was in. I also received a message about all Asiatic boats were to base out of Fremantle, yet I am still showing Surubaya as my base of operations.
...
So for stories, this is more of a memory. When I was young my sire got me hooked on Submarines and the Navy. We had a C128 and Silent Service. He created authentic looking (at least to me)patrol sheets and had manila folders with colored tabs that you could slide paper into. You named your Sub then you did patrols. After each patrol you had to fill out a patrol report.
If you lost your Sub it was "stricken from the record" a new name was slid into the tab and the patrol reports from your sub were put into an "Archive".
Between that and books like, "Wake of the Wahoo", "Silent Victory", "Sink 'em All", "Iron Coffins", and while fictional, "Das Boot", and "Final Harbor". Final Harbor was why I would usually name my Subs U.S.S Mako.
And while Movies like "Run Silent Run Deep" and "Das Boot" were staples of my childhood, I find it funny that when things like Mogami Class Heavy Cruisers are mentioned that I think more of "They were Expendable." Hmm... I wonder if there is a PT Boat Simulator out there.

FOTRS V1.8 with Nippon Maru, Nihon Kaigun,
vickers interiors,
plus my custom mods to FOTRS... campaign traffic
darker nights/ historical night surface attacks, wolfpack mod (in testing)
100 difficulty, cams off, map contacts on)
USS Parche SS-384 (Balao Class)
LCDR Lawson P. Ramage, Commanding.
(This is a historical engagement I added into the mod, with convoy MI-11 (See Ramages Rampage) and a pack of three US Submarines...Parche, Hammerhead and Steelhead)
This was my first real engagement in FOTRS V.1.8
Departed Pearl Harbor on July 4, 1944 for Luzon Straits, stopping at Midway for fuel.
Passage to area was uneventful, other than a few aircraft.
On 24 July, SJ radar detected what turned out to be a unidentified fleetboat, but believed to be one of our packmates, possibly Steelhead.
On 30 July received contact report on large convoy departing Takao. Positioned Parche in Luzon Straits for intercept.
At 2304 SJ contact was made on convoy at 17000 yards estimated range.
Convoy was in two large columns, estimated 18-20 ships with 6 known escorts. Convoy was plotted on a SSE course at contact making 9 knots. Went to GQ and closed to visual range, transmitting contact report at 2331.
With partial cloud cover and no moon, conditions were perfect for night surface attack.
Just after midnight on 31 July, convoy zigged to SSW, throwing Parche out of position. Increased to flank speed and maneuvered to attack from up moon of convoy.
At 0100 a escort fell out of position to "sweep", permitting to close in to just 1900 yards from port column. Targeted three Mk 14 torpedoes at a large troopship and three at a large tanker.
At 0111 Fired tubes 1-6 at troopship and tanker, turned to port for escape and to bring stern tubes (MK 18-1) torpedoes to bare.
At 0112 Torpedoes hit both targets. The troopship caught fire, and slowed, listing. The tanker erupted in a massive fireball after first hit, the next two torpedoes being redundant, somewhat.
Parche quickly came under heavy machine gun and deck gun fire , illuminated by star shells and searchlights. A escort similar to a Type C began pursuing as Parche put on flank speed. A few errant machine gun rounds hit Parche, but no damage was suffered.
As Parche fled lined up on a merchant and fired four MK 18's from tubes 7-10 from 2200 yards at 0114. Three of four torpedoes hit the target at 0116, erupted in a fireball. Bandoeng Maru 4070 tons sunk in less than two minutes.
Now Parche had a new problem, the minesweeper on her tail at 3000 yards and the now alerted escort, which fell out of formation earlier to "sweep" now alerted and barreling in towards Parche, Put 15 degrees starboard rudder to create a slow swing and change in course to avoid on rushing escort while keeping the minesweeper astern.
0118 Troopship identified as Kiturin Maru 5083 tons sunk. Some boats spotted in water.
0120 Tanker Itukusima Maru 10,020 tons sunk.
Parche continued to take fire but managed to evade both escorts and disappear into the night. After slowing, began torpedo reload on surface
(during real engagement, Ramage ordered this, which was not normal for us sub ops at time, while on surface and still in contact with enemy and not submerged, which was SOP at the time)
Noticed convoy began to regroup somewhat minus two escorts searching for Parche. Depth charge explosions were observed/heard in distance, convinced Parche submerged.
At 0300, with torpedo reload completed, closed convoy for another attack.
At 0321 fires and explosions were observed in convoy, which was 8000 yards astern to starboard, likely torpedo hits from another US sub (AI subs firing torpedoes).
"Thunder" was heard as gunfire, star shells, depth charges were plentiful from starboard side of convoy. Parche closed from port and worked inside convoy. Sighted large tanker similar to Itukusima Maru ahead to starboard, constant helming at 6 knots. Fired tubes 1,2,3, (MK 14) at 0341 from 2200 yards as tanker began swing to port. At 0342 three torpedoes hit, setting tanker on fire, causing it to slow. This southbound tanker was apparently empty of volatile fuel load and thus did not erupt in expected fashion of a loaded tanker.
With Parche, now building up speed to cross inside convoy and under fire,
adjust speed, AOB on tanker, sent new TBT bearing and fired one more torpedo from tube No.4 at 0343.
Torpedo hit tanker under aft stack at 0344, causing a large explosion, likely from her boilers. Tanker began to sink by her stern. Uknown tanker similar to
Itukusima Maru 10,020 tons sunk at 0350.
Parche was now crossing between the two columns , constant helming. Targeted tubes No.5 and No.76 at unknown merchant of estimated 5000 tons. Fired both from range of 1900 yards at 0347. One torpedo hit, other
appeared to pass below target(!). Ahead flank was ordered to avoid gunfire and the damaged but underway merchant, which appeared it would attempt to ram. (Parche was nearly rammed in real life during this engagement as well).
A destroyer believed to be of Fubuki class was spotted astern closing at high speed. Unable to outrun, prepared stern tubes for "down the throat shot".
However, this shot was proven not necessary as the destroyer lost contact with Parche. With torpedoes aft, ordered bow tubes reloaded with final four torpedoes (MK 18-1) and turned to port to come about for another surface attack before dawn.
At 0440, with bow tubes reloaded, moved in for surface attack. Set up on
large troopship for attack with stern torpedoes. A alert escort spotted Parche at 3000 yards, forcing a shot on a nearby merchant instead of troopship.At 0456 fired tubes 7,8,9,10 from 2400 yards, then increased speed to flank, put closing escort (identified as Type C) astern. Two of four torpedoes hit the merchant vessel (estimated 5000 tons) at 0459, soon large fires were observed, unknown vessel sunk at 0503.
Meanwhile, the escort and two others were in hot pursuit of Parche which was cutting through the seas at 21 knots, dodging shell splashes of gunfire. Eventually, Parche pulled away from escorts.
Although dawn was sometime away, a glow developed as a quarter moon had risen, which would prevent further night surface attacks. Secured GQ and cruised ahead preparing for dawn periscope attack.
Lost SJ contact at 0521. At 0600 SD was powered on for sweep. Just after turning SD off, APR-1 detected radar emissions. A quick SD sweep revealed a aircraft at 20000 yards and closing. Parche submerged to 100 feet at 0601 and surfaced at 0610.
Another dive at 0801 was required due to night aircraft(base time, still dark in area). Surfaced at 0830. Back on top regained SJ contact with the convoy at 0901 in the pre dawn skies.
After countering two ziggs and dodging aircraft, submerged for attack at 1145. Went to GQ and conducted approach. Due to escort screen, would have to fire from 3000 yards.
At 1214 fired MK 18-1 torpedoes from tubes 1,2,3,4 at troopship Corona Maru (12000 tons) in center column. During torpedo run, Parche was detected, possibly by aircraft overhead. Escort closed, began pinging.
At 1217 two torpedoes slammed into Corona Maru , setting it afire and slowing. One torpedo which missed the troopship, hit merchant similar to Akita Maru in far column. With a Type C escort closing in fast at just 1100 yards, ordered 500 feet, rigged for depth charge, and silent running.
As Parche passed 334 feet, large pattern of charges exploded about.
Minor leaks in piping and air lines occurred, but no serious damage.
Parche leveled off at 500 feet and endured several close patterns of depth charges. At 1402 close charges caused flooding in forward torpedo room. Flooding was quickly contained. Parche reached 550 ft. Most escorts seemed to move on but one remained in area hunting. Finally appeared to loe escort at 1600 hours. Parche secured GQ but remained deep and under silent running conditions.
At 2100 hours, came to periscope depth, all cleared, secured and surfaced.
Set course for Midway, where patrol was terminated on 19 August.
Jolly Good fun in FOTRS:Kaleun_Salute:

after torpedoing this merchie we watched her sink.
we figured the guy in the middle was walking a tightrope in order to move from the sinking aft portion of his ship to the less sinking portion of the forward part of his ship.

What is your mod list there smm? The SH4 completely ignores attempts to tame the Mark 10, which means we rely upon the player to keep them on impact pistol...
https://www.subsim.com/radioroom/picture.php?albumid=1070&pictureid=13120
The Mark 10 did not have as high of a chance for duds as the Mark 14 did, by a long shot. There were some, usually "wandering" on their track, or sometimes a circle runner, sometimes no detonation upon impact, but generally rather reliable torpedoes, if a bit anemic in the explosion strength. One thing to watch for with the S-Boat, is that since the Mark 14 torpedo is listed first in the Weapons upc file, if you empty your stores while on patrol, when you come back in to dock and End Patrol, the game will load you up with Mark 14 devices. Easy enough to change, if you remember to do so, or prior to docking, go ahead and do the re-arm choice, and load-up on torpedoes, then dock. Just one of those SH4 kind of things. :salute:
What is your mod list there smm?
Just FotRSU 1.8
I didn't play SH4 for more than a decade, and didn't really want to spend too much time investigating mods TBH :).
So went for this as a super-mod. Happy to hear about others that work well with that - especially if they work with an existing save :D

Thanks!
@Propbeanie - thanks for the Mk10 reload advice, saved some time with that!
Episode 2 now out (what is the etiquette here about that? post just the initial one, or any?)
https://youtu.be/X4nIim58GWk
As an entirely aside question (which I don't know where to ask) - is there mod for any SH/anything that would do UK subs Med campaign? It was pretty intense, with tons of IT/GE shipping to North Africa, shallow waters, lots of planes and very good IT ASW small boats - but didn't see anything on that anywhere, ever.

I encountered difficulty as I explained it... I separated myself from reshade last version... (but I have the attention to persevere in order to benefit again) :D:D
usually I never use I find that it distorts the work of modders...
Thing promised first night attack before my patrol Quadra..

I want to add the work on the burning oil is remarkable but with reshade it's misery!!! ...as well as other things...this work comes from the KsD team ...as well as from comrade Lukner all credits are given to them
as well as to master vickers03 and Niume for the translations which represents a huge block of work great respect to them :yeah::yep::yep::Kaleun_Cheers:

@boapiu many thank's :salute:
DateTime 1939-08-27 it is around 10.30 a.m. I arrive a few miles from my "Quadra" North West England.. In very good weather taking advantage of my electric batteries... surprised by a destroyer at around 8 to 10 km to the Nord west he immediately opened fire... emergency dive 140m ..Combat post...
He harassed me for 1h30 then I studied his patern, timed him... then I attacked him... inscencer thing..!! I must say that the work of Kerllermann 1.3 is a pearl.. it is very difficult to take an attack position, especially with the innercie going up. I approached at 450m... he rushed straight at me...
He and pass very close to about 20m... to grenade.. I suffered a few scratches 3% a "bagatel"... as I expected these grenades to be thrown too far... I was hot.. then qu he was in front of me he started his circle... then in the periscopic position a "pistol" torpedo finished it... at the port aft transmission shaft... I must say that this "dangerous" attack gave me extreme tension... I'm happy.. to have it on my hunting board...:D:D

Class Benson... By the bottom:D
the attack began at around 4:15 p.m. this one was very clever.. I was at 20m at 1 knot.. total silence at around 2000m he immediately began the search...
It took 3 torpedoes... to shoot it down... a really dangerous target...!!! prepare your attack well.

"A thorough examination of a WWII submarine. Our creation is a generalized model taken from Gato and Balao class boats."
https://youtu.be/FctRpaleRFc
This is a great animated video showing in general the inner workings of an American submarine. This was produced by two hep cats named O'Neal; they must be a relation to someone here!
Jacob O'Neal - Modeling, animation, texturing, vfx, music, narrative script
Wesley O'Neal - Research, technical script
It is a very interesting representation of the submarine especially the way it gives you an almost visceral understanding for where everything is located and how all the systems are interconnected. It made me appreciate more than ever before how these magnificent submarines were engineered.
Thanks for the advice Aktungbby ( you're not that dumb after all )

this is a screen shot of a IJN DD/DE that was split in half by my crew.
the after half sank while the forward half sailed on.
we had other fish to fry, so to speak, and i never went back to see if this piece ultimately sank.

this was during a Late-May 1943 patrol NE of New Ireland.
we stayed at PD too long...acting like a bold submariner instead of an old submariner.
...and we were pummeled. you need to look closely in the middle photo to see the DC descending. that is the one you see exploding in the third photo.

Hello KM :salute:
I find it very good the break of several days it gives a good general impression our submariner did not encounter ships every day...it suits me...you should know that I saw a few targets but it was the small fry... :salute:
i agree with you.
however, one can setup traffic using the game-dice-rolls (spawn chances) and time intervals to vary the "possibility" of the traffic spawning.
that's a nice feature to have in one's pocket for obvious reasons.
if i wanted to be bored-out-of-my-skull, i would go and visit with my in-laws.:haha:

we made it back to base, despite the massive damage.

I don't use any tricks.... I simply use the game software for the screens... no Reshad.. no ENB.. or other etc... the screens are "in game"... no subverfuge ... the game's capture software is bad... in game it's much better... it tends to darken the photos... and it lacks image precision..... maybe look in sticky from Peter... there is always good advice in this database....
The modding of the FORTS team is very good graphically...(ThX masters Vickers...).. not physically enough...Beanie lets me understand that he will do what he can...!!!:yep::subsim:

Do you use the glare option in graphics? I can´t use it because I need to put "antialiasing compatibility" with "Diablo III" option in my Nvidia Inspector, or I lose all the AA. And with the Diablo III option, I have ugly bands in the graphics when I use the glare option.
Best regards.

I don't use "antialiasing compatibility" mine is on Application-controlled antialiasing...
I don't use Diablo..I use 0x00000000...
the graphics can vary very quickly from one PC machine to another PC.. you can spend hours on it..so not obvious... I must say that FOTRS is very beautiful... when it is well adjusted....that I've been modding these Series Silent Hunter3 4 5 for a long time now..
I must say that the mods can be difficult to adjust..some can go very well and others can be difficult..but I never play without them...Special ThXXXl to Maitre Vichers these mods really bring a lot here...in FOTRS

On approach at 20 fts then 15 fts I almost touched the bottom...:D:D
I suppose you are asking this question because of the underwater reflection...I must say that this game never ceases to amaze me graphically, especially when it is well adjusted...:timeout::har:
The work of RFB 2.0 is a must plus this mod is very old..there are certainly some small errors..but nothing that prevents you from playing..if only Ducimus would resurface again...that would be great. ..

When carrying out this rescue mission the script does not trigger even when describing a circle 5000 yards around the point in question... do you have an idea?? Besides, it's not the first time that I've been bothered with this kind of mission, it's a bit painful...

Some screenshots from my Phillipines campaign.
Started with an S-boat and finally, in mid 1942, I've got my first fleetboat.
And during a deep dive trial, I found out how the US won the war.
S-39 has done its duty, I am a bit sad to let it go but USS Seal is just superior in every way.

nice video!
so, did you plan to shoot at both cruisers or only one of them?

Thanks! :salute:
It wasn't really my intention to hit them both (I'm not that good, and the British torpedoes with 0º of gyroangle make it hard to fire at different targets at the same time). The salvo was aimed at Bolzano. The light cruiser got in the way.

41/12/24 0800 GMT+11: We are 5 miles off the north coast Of Pohnpei Island. Course 90 degrees T at 1 kt, depth 90 feet. That's the island about 400 nm east of Truk Atoll and 550 nm west of the Marshalls. Since at least 1832 it has been called Ascension Island (according to ONI's research conducted in the archives held by the Harvard School of Anthropology/Archeology) but the Navy wants us to show deference to native place names and customs. And no, as my Ensign Bisell found out, that doesn't include anything Japanese. I have gathered my Officers in the wardroom for a little chart study, except for Ensign Can't-find-his-ass, who is the OOD with the admonition 'don't run into islands'.
Problem: best approach into Kolonia Harbor given ONI wants pictures and I want to sink whatever is in there, my version of a mini Pearl Harbor. Kolonia Harbor has two port facilities. Now there is an outer northern port which we have glassed thoroughly. It's got four slips with a 10,000 ton tanker in slip1, as numbered north to south, and some kind of gunboat in slip 3. Both moored stern in. The gunboat is in the class with 4 funnels, looks to be maybe 800 tons. Got a 3 inch and a 25 mm at the bow and I don't know what is mounted at the very stern but for certain two 13.2's "up on the roof" aft the bridge. The inner southern port is the one we can't see into very clearly but it looks like there's a moored freighter: raised forecastle, mast, funnel, mast, raised poop. Definitely runs on coal. She is not in a slip, strange.
"Getting in will be easy, the channel runs north-south and some markers are still up." LT jg John Long runs navigation with the easy assurance of a man born into manners, grace and style. "The depth outside the harbor has averaged no less then 65 feet so we may be able to go in submerged. They got that tanker and freighter in there so we know there is depth." He double taps the chart with the eraser end of his always sharpened pencil. "Here, between the inner and outer port is that mini-mountain. Slope of about 40 degrees...slides clear down into the channel. That's gonna be a pinch point."
"So stay close to Sokehs Island?" I ask. The channel's western shore is actually part of Sokehs Island. A very narrow winding channel at its south end separates it from the Pohnpei Island. The channel, Dau Mwoakoter Channel, connects the south end of Kolonia Harbor with the the big blue Pacific. Just a blue squiggle on the map, could we use it?
"I'd say stay about 100 yards from the channel's west shore. The mountain wall bordering the west shore is steep and cliffy so not much beach meaning not much mangroves." Mangrove roots trap the silt, creating tidal flats, which grow more mangroves which create more tidal flats. Give mangroves an inch and they'll create their own tidal flats stretching out 200 yards.
"Wouldn't worry too much about the mangroves; worry more if they got that 15 cm gun emplaced on top of Sokehs Mountain yet Would cover the entire channel. See the northern third? It's a spiny ridge but the southern end plateaus out pretty flat." CPO Willis Bole traces the elevation markings with a stubby finger. He spent time on board destroyers, '17 to '28, before volunteering aboard the boats. I specifically invited him today.
"Means we can't hope to pull a "Washington across the Trenton" and silently slip by those drunken Christmas Eve watch standers while surfaced, even decks awash." Almost wistfully uttered by LT jg Bladen Walsh, a man born after his period.
LT jg Marion Andrew, out Engineer, primly delivers his viewpoint. "Japanese don't do Christmas cause they are Buddhist or Shinto or some such sh..."
"Yeah but the natives are Christian so the whole island is got to be celebrating. You know how on Hawaii the Orientals love to celebrate?" Don't know who interrupted Andrews that pearl but oh, that did it. Everyone had an 'oriental celebration story" or three and they were off and running with it.
I'd normally rein them in at this point but this gives me a moment to think. OK, we are tasked with surveilling the outer harbor, see what is in there. Already done. The real importance of the island dots in this atoll isn't Pohnpei. It's Lenger Island to the Northeast. The Japs are perfecting a seaplane base and ramp there. An H6K Mavis out of Lenger could bomb Wake, hunt subs in the Coral Sea, deliver VIPs to the Marshalls. Dangerously impressive. But as Lenger has no natural port like Kolonia, everything such as fuel and bulk material has to come to Pohnpei first and then gets lightered over to Lenger. Know the tonnage coming into Pohnpei and you know the tonnage going to Lenger. Simple tonnage story. Although we are not tasked specifically with penetrating the inner port, I have decided to read the orders as giving me that initiative because taking those pictures will show the cumulative tonnage both ports can handle. Enhancing the tonnage story!
So, what are our options? We can run in and get our fabulous pictures, thereby showing initiative and daring in the best traditions, etc. Or run in for pictures then sink the freighter on the way out. Create confusion to cover our retreat. Or take pictures then sink both the freighter and tanker, hoping the latter is full of AV gas and maybe the former is to the gunnels full of ammo. Won't know till we sink 'em. But whoa, imagine those snaps! Or take pictures then sink freighter, tanker and gunboat. The problem is the gunboat draws so little water that we'd have to gun it not torp it. The problem of command is always in choosing the best option among many. But sometimes, as the saying goes, the best choice is clearly black and white, like a school bus full of nuns. Like here. Chief Bole is coming to the end of his celebration story involving his destroyers days. Not involving a single nun. Time to get my boatload of brothers back on the oars.

this was one of those infrequent moments when you decide to use the exterior camera and see something very unusual.
Background: we were on patrol in the Bismarck Sea, and, periodically an IJN PT Boat comes out and patrols then returns to port.
in these two instances, the PT was out patrolling and a flight of USAAF B-25 Mitchells were flying over...and of course the AI dictated that they should attack the PT.
so, two separate PT's, subjected to two different attacks, at two separate times.
PT 1 did not fair well.

I just need to share this story and vent a bit. This game can be so frustrating and awesome at the same time sometimes. So: SH4+RFB+RSRDC.
3rd or 4th patrol in a pig boat, home base Fremantle. Japs already rule Java and I get an assignment to the Sibutu Passage, deep into enemy waters and quite a ride too for the S-class. But OK, I go straight in, past Bali and through the Makassar Strait with plans to refuel in Darwin on my way back. I bag two merchants on my way there and three more in the Passage. It was a turkey shoot down there, they just kept coming one after another (by RSRDC standards, it was still just one vessel per day). I run out of torpedoes, complete the assignment, get on my way back home with 28k tonns. A very successful patrol, I hope for a fleet boat promotion on return. Short stop in Darwin and on my way back to Brisbane. With just about 10 NM left after a long voyage I enter the Moreton Bay at 512 TC on the map view.
Suddenly... a ship contact on top of me and before I can do anything I hear loud bangs, water leaks and damage reports! I reset TC to 1x, switch to the external view and instead of my boat I see what looks like a British Kent class heavy cruiser slowly drifting in a thick fog. My sub is already at the bottom of the bay at 270 feet, with all compartments flooded and half of the systems gone.
So what happened? By the extent of damage I'm guessing my boat jumped just in front of the cruiser in this damned fog and got rammed and pushed under water. Had the sub rammed the cruiser I doubt it would've sinked so fast, if at all. The deck crew was gone but surprisingly the rest of the crew was still alive and fighting for their lives in the crippled hull. I formed a damage control team and for a while it looked like there is a chance. They managed to repair a system or two. But eventually, after about an hour of fight, the hull gave up...
Instead of a new boat I got the post-mortem Medal Of Honor and a statue in my home town...
So... I not even mad. Or maybe I am about clunky game mechanics. But also I'm in awe. What a frustratingly awesome story. A sub returning from a month long successful patrol collides in a thick fog with a heavy cruiser of all things, and sinks with all souls on board just a few miles from home. I don't know if something similar ever happened in reality but it definitely could have. I just never expected to experience something like this as an unscripted event in Silent Hunter. Had I run at lower time compression I probably would have time to hit the brakes and could save the boat. This is how it would have ended in reality I suppose. But I won't be reloading this patrol. I'll just keep it in memory as the most epic end to a career in SH4 so far. And maybe get a break from SH4 for a while...

yes, that can happen, especially when you are steaming near a port and at TC greater that 8 or even 4.
there are a LOT of collisions in these types of apps and high TC prevents your sensors, even the human ones, from detecting an intersecting object with enough time to react.
if you were at 1x, the cruiser MAY see you in enough time to change course, however, in a fog/storm, it would be tough to predict.
as you discovered, the best way to avoid this event is to slow the TC when you get to areas where other ships can pass. Ten miles at 512x is too-fast-too-close.
typically, i slow the TC when we are 50-60 miles out from any port, friend or enemy.
good luck, next time out.

TMO Update BH 2.1 (testing improvements for forthcoming V2.1)
100 difficulty with external cams off, map contacts on.
First patrol for me in a LONG time. Working on update to my mods for TMO, testing things out. Three patrols, ran well. This is the report for the first war patrol.
I began a new construction career in 1942, assigned the USS Wahoo SS-238. After commissioning and workups on the west coast, headed for Pearl Harbor. Assigned patrol North-West of Truk near Namonuito Atoll and the Hall Islands as well as approached to Truk in the Caroline Islands (as Wahoo was on her first patrol if I recall), departed on August 18, 1942.
WARP PATROL NO.1
18 AUGUST-OCTOBER 21, 1942
En route to patrol area , conducted dive drills, battle surface drills for gunnery, as well as submerged tracking and torpedo fire control drills on US flagged merchants. Trim dives conducted at dawn, after noon position, and at dusk each daily. Transit speed on surface was 15.5 knots.
Upon reaching 400 miles of Truk, submerged daily at dawn for submerged run. Wahoo ran at 90 ft submerged with sound constantly monitored, rising to periscope depth for observation every 35 minutes.
Large flying boats presumably from Truk were observed on average of twice each day, usually a H6K "MAVIS" type, although a "EMILY" H8K type was observed several times. Wahoo was not detected.
Wahoo entered assigned patrol area on 25 August 1942 at 0000 hours, patrolling area at 12 knots, diving each morning after dawn to patrol submerged. Each morning around or just after dawn, an SD radar contact was made or periscope watch observed a daily flying patrol heading NNW away from Truk. Wahoo remained undetected.
TORPEDO ATTACK NO.1
Wahoo submerged for the day at 0715 hours on 26 August, 30 nautical miles East of Namonuito Atoll Atoll in the Caroline Islands. At 0740, sound detected light, fast props closing, bearing 010. Ordered closing course accordingly and soon realized we had a possible submarine. Ordered General Quarters-Torpedo Submerged at 0752. At 0801, made visual contact with a surfaced submarine closing Wahoo.
Ordered 100 feet and conducted a port turn off track, and circled back to bring bow tubes to bear, to bring Wahoo to an estimated 900 yards firing position. Returned to periscope depth and conducted approach, identified as a Japanese I-Class Submarine. Course 160 degrees at a speed of 14 knots, likely heading for Truk. Seas were calm with light chop, visibility excellent. Yachting weather. Tubes 1,2,3, and 4 were made ready. Torpedoes set to depth of sex feet.
On observation at 0812, the enemy submarine was in firing position, fired three torpedoes. Using spread knob on TDC, one amidships, one towards bow, one towards stern at 0813. Torpedoes 1 and 2 appeared to prematurely explode and upon raising the scope, the now alerted submarine, evaded third torpedo. However, the submarine put Wahoo in a decent firing position with its wild maneuvering, and torpedo number 4 was fired from just 700 yards. This torpedo's wake was observed to run directly beneath the enemy submarine (as it sharply turned towards Wahoo apparently spotting our scope and firing machine guns) ad exploded just astern of the submarine, likely causing damage due to its proximity. To avoid being rammed or damaged by gunfire, Wahoo made an emergency descent to 90 feet.
During this time, Wahoo lost sound contact with the submarine.
At 0825, came to periscope depth. As we rose, sound contact was reestablished and upon raising the scope, observed the enemy submarine distant in horizon on course 150, zigging slowly, likely damaged.
Battle Surface was called and surfaced at 0830 at full speed, to close and engage the damaged I-Boat with guns. As we opened fire from 6000 yards and scored one visible hit, SD radar had fast closing aircraft. A dive was ordered. As Wahoo passed 100 feet, multiple large explosions heard, presumably bombs from nearby aircraft called in. Contact with enemy submarine lost at 0836. Submarine damaged, not known if sunk or submerged or escaped on surface. Secured from GQ at 0900. Enemy aircraft kept Wahoo submarined remainder of day. At 1130 hours, a pair of Momi Class DD's were observed in area where Wahoo had been bombed by aircraft, apparently called in to search. At 1500, Wahoo went to 300 feet, silent running as one DD passed within 2000 yards, but did not detect. Wahoo remained at 300 feet until surfaced after nightfall 2100 hours and set Course to patrol off Truk's Eastern pass.
27 August was a mundane, routine submerged patrol off Truk's eastern pass, observing only patrol planes and vessels via periscope and sound. Surfaced for nightly battery charged and looped the areas East of Truk, returning to the spot 10 miles off east pass to submerge at dawn.
TORPEDO ATTACK NO.2
At 0905, sound picked up heavy screws a 274 degrees. Wahoo turned to approach and soon heavy masts were observed over the distance, the distinct masts of a large IJN warship, possibly a BB or CA. At 0916, General Quarters Torpedo-Submerged was called. On observation at 0925, a "PETE" single engine floatplane was spotted flying ahead of the ships, forcing Wahoo to submerged to 100 feet to avoid being spotted. At 0940, Wahoo returned to periscope depth and observed in a single column a CVE, BB, with three DD's escorting. Wahoo went to 150 feet to maneuver off track, turn back around to bring bow tubes to bear, returning to periscope depth at 0955.
The BB was identified as a Yamato Class Battleship, with a Taiyo Class CVE with three DD's presumed to be Asashio class on course 088 at 21 knots.
Wahoo went to 100 feet and maneuvered to keep out of the lead DD's presumed sonar "cone." Rising back to fire from ahead before to starboard escort detected Wahoo, lady luck shined as the escort dropped out of position to make what appeared to be a routine sweep, this would enable to fire from ideal range of 1000 yards with perfect AOB. A speed check showed the force had slowed to 16 knots, likely slowing as approached the East entrance to Truk Atoll, some less than 6 miles away. Torpedoes were set to 20 ft depth, all tubes flooded, outer doors open.
At 1004:21 hours, raised scope as was in perfect firing position and fired spread of six MK 14 torpedoes all set at 20 ft depth with 2 degrees spread using spread angle knob on TDC. Ordered hard left rudder to begin turn and bring the stern tubes to bear.
Three bow torpedoes prematurely exploded, one missed (appear to run deep, observed wake) but two hit. One hit the bow and one the stern of the Yamato at 1005 hours. A serious fire erupted on the bow and forward area of the BB.
With aft tubes flooded, DD's pining bearing down, fired all four torpedoes at the damaged BB, now slowed to 10 knots with visible fires raging. Popped scope up to observe all miss and two prematurely exploded after running below target. A PETE floatplane was spotted low, barreling towards our scope, and all three DD's closing in fast. Wahoo went to 300 feet, rigged for silent running and depth charge.
As Wahoo passed 100 feet, she was rocked by explosions from the PETE's aerial bombs, but no damage. Wahoo leveled off at 300 feet and soon after the first DD passed overhead, dropping a pattern which shook the boat, causing minor damage. Soon the other two were overhead, with similar results. In the post explosion confusion, Wahoo went to 325 feet and turned to 280 degrees at 2 knots. A close pattern causing minor flooding and damage at 1025 caused Wahoo to go tot 350 feet where leveled off.
By 1300, the DD's appeared to have lost the trained. Wahoo secured from GQ but remained on silent running at 350 feet, course 270, away from Truk. All clear by 2200, Wahoo surfaced after nightfall and proceeded to leave area as it would surely be a hornets nest for days coming. One large BB logged as seriously damaged by two Mk 14 hits on bow and stern area.
Note: On August 28, 1942, the USS Flying Fish SS-229 did actually encounter the Yamato as it arrived off Truk. Four torpedoes were fired, but all missed. This contact was added to the campaign as part of the mod as a "historical contact" sometime ago, where if player is in right place right time, has the chance to run into certain vessels. The fun of this as I've been away for a long time from SH 4, I forgot about this contact until I saw it was the Yamato. Quite a thrill.
At the time, Yamato Class was not in the ONI Vessel Identification Manual and Flying Fish's Commanding Officer logged it s a Kongo Class.
The days and weeks following the attack were mundane, routine. Wahoo patrolled the approaches to to Truk from the Northwest and North, making no contacts, only observing patrol planes through the periscope.
On September 22 at 1405 hours, while 15 miles ESE of Namonuito Atoll spotted smoke through the periscope at bearing 095(soon confirmed by sound) on what appeared to be a southerly course. Immediately turned Wahoo to parallel course and surfaced to pull ahead, keeping distance to avoid being sighted, using the SJ radar to track the vessel. By 1600 hours, Wahoo was ahead and submerged 10000 yards off projected track, began closing what was tentatively identified as an AK (merchant, cargo vessel).
During a classic periscope approach, observed an AKITA MARU Class AK on course 200 at 9 kts, unescorted. The AK had a deck gun forward with machine guns/auto cannons mounted. Cargo crates were visibly on deck.
At 1647 hours, Wahoo was 1000 yards off the port side, the scope was raised and three torpedoes were fired at the AK. Torpedo one hit the vessel amidships, leaving a large, gaping hole , causing an explosion and fire. Torpedo two missed ahead as vessel slowed, Torpedo three missed, its wake observed passing beneath the stern of the vessel.
The ship was soon dead in the water, her boilers and engines apparently knocked out, and listing to starboard. Tubes 4,5,6 and were made ready for firing and with the maru dead in the water, torpedo 4 was fired at 1700 hours. The torpedo hit the vessel but did not exploded, a dull "thud" or "clang" was heard with its impact, an apparent dud. The maru's guns began firing at Wahoo's periscope. Wahoo dropped scope, went to 75 feet, and made a turn to port to bring stern tubes to bear, coming back to scope depth in the pre dusk afternoon.
Tubes 7,8,9,10 were flooded, torpedoes set to minimum depth and tube no. 10 was fired. The torpedo hit and exploded, setting off a massive secondary explosion and fire. The maru began listing heavily and was observed to sink at 1801 hours. Wahoo set a course away from the area and secured GQ, surfacing after dark.
The days following Wahoo's first sinking were routine, spotting only patrol planes. On September 29th just after dusk, SD contact detected a rapidly closing aircraft. A crash dive was ordered and an unseen plane bombed Wahoo as she passed 85 feet, shaking the boat furiously and causing damage to forward batteries, trim pump, as as well as leaks in piping, high pressure air lines, broken glass. Two crewman in conning tower suffered minor injuries. A close call. After surfacing at 2300 hours, Wahoo set course for Ulul Island area to NNW.
TORPEDO ATTACK NO.3
On October 1 after dusk, Wahoo surfaced into heavy seas with light fog and heavy cloud cover. At 0330 hours on October 2, while 30 NM NW of Ulul Island, SJ radar made contacts bearing 160 13000 yards. Wahoo swung about and heading to intercept, soon SJ detected multiple contacts.
Position keeping and tracking were made difficult by the heavy seas and conditions but SJ maintained contact. After a trim dive at dawn, resurfaced and closed on surface until smoke was sighting in the cloudy conditions. Wahoo submerged directly ahead at 15000 yards and closed, then moved off track, looping back for bow approached.
On the 0800 observation , the skies and seas were now gray, with a fog making visual identification difficult. However, the vessel was identified as a 10,000 ton AO (tanker) of the Nippon Maru class on subsequent observations. Tubes 1,2,3,4,5, 6 were made ready and at 0820, tubes 4,5,6 were fired from a range of 1000 yards. Torpedo prematurely exploded , which caused torpedo to exploded as well. This alerted the tanker, which turned hard to port. I observed the torpedo (aimed at middle of the target), miss just ahead of the bow due to the skilled turn of the tanker. The torpedo explode don its own just seconds after missed.
A large, unidentified by possibly Fubuki class DD was soon charging Wahoo with a bone in her teeth. Wahoo turned into the DD and prepare for bow shot or "down the throat" shot but could not line up in time and went for the "express" plunge to 300 feet, rigged for depth charge and silent running. The DD's first four passes were skilled and close with the third pattern causing
minor flooding in after torpedo room with damage to electric engines 1 and 3, trim pump, hydraulic pump, air compressor, along with busted pips, air lines, light bulbs. Wahoo went to 325 feet and soon evaded the DD, with heavy seas no doubt aiding in the escape. Wahoo secured GQ at 1000 and silent running at 1100. Coming to scope depth, found storms raging and zero visibility. Wahoo remained submerged and conducted repairs, surfacing into storms at dusk. Storms raged in area until October 5th, with choppy seas persisting into the next few days.
With time on station winding down, Wahoo ventured back into the waters west of Truk on October 6th, conducted submerged daytime patrols in area to interdict traffic in the area. On October 9th sound detected heavy screws near Truk but the unknown contacts entered Truk before could be identified and intercepted. At midnight on October 11th, Wahoo terminated patrol and set course for Pearl Harbor as fuel situation required.
Foul weather covered Wahoo's exit over next wee days, allowing daytime transit on surface. Wahoo arrived Pearl Harbor on 21 October 1942 at 0900 hours and terminated patrol.
Results: One AKITA MARU class merchant vessel sunk by torpedo.
One Yamato BB damaged by torpedo
One I-class submarine damaged by torpedo and gunfire, possibly sunk.

War Patrol Report
USS Wahoo SS-238
War Patrol No. 2
7 November-28 December 1942
Returned from first war patrol 21 October 1942 arrived Submarine Base Pearl Harbor, Territory of Hawaii. Following leave, upkeep, training period, ready for sea 6 November 1942.
Departed Submarine Base Pearl Harbor at 0800 on 7 November for assigned area south of Truk in the Truk-Rabaul shipping lanes in support of ongoing operations in the Solomon Islands area.
At 0845 conducted trim drive, surfaced at 0900, set on course 235 at 15 knots. At 0934 SD radar made contact at 8 miles. A PBY patrol plane 11-P-10 was spotted, recognition signals exchanged. However, the overzealous piloted plane made a dive at the Wahoo (friendly fire mod ) necessitating evasive action at flank speed and turn to port as aircraft dropped bombs which exploded off starboard side. A crash dive was ordered and Wahoo submerged to 150 feet.Wahoo surfaced at 1400 and continued on, diving twice more for SD contacts, surfacing at 1900.
The transit to the patrol area was uneventful and entered assigned patrol area South of Rabaul north of Bismark Sea, roughly half way point between Truk and Rabaul on 16 November. Initially attempted cruising on surface in open sea areas. However, air patrols necessitated submerged patrolling.
TORPEDO ATTACK NO 1.
17 November 1942
After the morning trim dive at 0600, surfaced for morning position and to patrol until time for daily submergence for patrol. At 0650, SJ radar made contacts bearing 020 14000 yards. Ordered intercept course at full speed and
soon made contact with two CA, one CL, four DD on course 025 degrees at 20 knots. Possible warships heading for truck. Flank speed was rang up and shadowed at max distance. A contact report was transmitted.
The pursuit was difficult even though Wahoo was ahead due to floatplanes likely from the cruisers patrolling the area. "DAVE" and "PETE" single engine floatplanes were observed via periscope. In addition the warships made several zigs. At 1300, the force zigged back wards Wahoo and placed Wahoo in ideal position for submerged approach and attack. Wahoo submerged at 1310 some 8,000 yards off the vessels projected track. At 200 feet, Wahoo closed at 2/3 speed. General Quarters-Torpedo-Submerged was called at 1315.
At 1330 came to periscope depth for observation to confirm sound tracking. The cruisers were right on, closing fast about 10,000 yards estimated. Speed was plotted at 24 knots, course 345 degrees in a single column as follows; Fubuki DD, Fubuki DD Nagara CL, Takao CA, Takao CA, Sendai CL Fubuki DD, and three others unknown DD's, possibly Fubuki class. Quickly popped up to 38 feet and sent contact report, then back to periscope depth, undetected.
Bow tubes 1,2,3,4,5,6 were made ready set for 12 feet. three torpedoes would be fired at each CA. At 1339, raised scope and fired three torpedoes at each CA from 900 yards, each with 2 degree spread.
Torpedoes were spotted, alarms audible and ships attempted evasive action. Torpedo 1 and 2 hit the first CA, but each failed to explode, with an audible clang--a dud!. Torpedo 3 ran below the CA's stern and exploded, but did not see to cause the expected damage. Believe torpedo ran deep and ship did not get full effect, but it did slow.
Torpedo 4 hit the second CA just aft of amidships, causing a fire and quick list. Torpedo 5prematurely exploded. Torpedo 6 suffered an apparent guidance failure and did not track properly. However, this let it to hit the trailing Sendai CL in the bow as she took evasive action to avoid colliding with the Takao CA in front of her in column. The CL was see on fire with visible portion of bow visibly damaged/missing.
The swarm of destroyers closed in fast as Wahoo rigged for depth charge and silent running. Leveling off at 300 feet, Wahoo conducted evasive maneuvers. The second depth charge run by a DD was close, causing minor damage. Wahoo went to 325 feet, then 350 feet but the DD's were first team. To get under the charges, Wahoo went to 375 feet. The DD's worked over the Wahoo well for over an hour when most screws were heard leaving area quickly. However, two DD's stayed behind hunting for sometime, locating Wahoo intermittingly and dropping charges, losing contact again. The hunt went on until 1400. Believing the DD's to be "playing possum", Wahoo maintain silent running at 350 feet, secured from GQ until 1900 when secured and surfaced after dark. By dawn Wahoo was back at scene of attack and found no signs of sinking. While both CA's and CL suffered damage, neither is believed sunk.
At 1000 sound made contact with a surface US submarine, was unable to establish identity. Likely US sub vectored to our contact report, searching area. (AI subs, both friendly and enemy, both surfaced and submerged are on patrol in the mod.) Avoided contact. Surfaced after dark.
Note: Wahoo's SJ radar suffered serious damage in the depth charge attack as did topside equipment such as SJ, SD, and Radio antennas, 3 inch 50 caliber deck gun, 20mm AA gun, and TBT. All were eventually repaired.
November 17-27 proved fruitless searching, diving to avoid patrol planes.
A status report was sent to command at 0000 on November 28, , in which Wahoo was directed to proceed to a new area off Bougainville, and patrol the northern Solomon Islands. After setting course, traveling out to sea east of New Ireland, avoiding most air patrols arrived off Buka, Bougainville by December 1st.
Several fruitless days of patrolling between Rabaul and Buka came about, dodging a few air patrol and patrol craft in coastal areas when decided to proceed down the east of Bougainville to reconnoiter Kieta and then the Shortland Islands in the Kahili area in Southern Bougaville, home to Tonolei Harbor.
On 6 December, received ULTRA of a tanker en route to Buin-Kahili Southern Bougainville. Within striking distance, Wahoo raced to reach ambush position before dawn east of Bougainville, just north of the entrance to the channel between Bougainville and Oema Island, a known shipping channel. Submerged at dawn to avoid being sighted from shore or by air.
TORPEDO ATTACK NO.2
7 December 1942
At 0830, sound detected heavy and fast screws approaching from the NNE. Periscope observation showed smoke in the distance bearing 050. Wahoo turned to position for intercept and went to General Quarters-Torpedo-Submerged.
At 0845, an AKEBONO MARU class tanker with a Momi Class Destroyer was
observed closing, turned to enter the channel. Wahoo was in perfect position to approach from port and began closing.
At 0854, fired tubes 3,4,5,6 at the tanker from 850 yards. Three torpedoes prematurely exploded and the fourth impacted under the stern stack of the tanker as it turned away to starboard, but failed to detonate. Another DUD!
The DD quickly located the Wahoo, which was heading to deep and turning away. As Wahoo passed 260 feet, a string of depth charges violently shook the boat, causing damage to various systems (see damage report), most serious of us being flooding in the after torpedo and engine rooms, which was controlled quickly but did cause some depth control issues for a time.
The DD seemed to be highly skilled as it stayed on Wahoo as passed 300, 325, then 350 feet. Causing more damage.
Sound soon reported new screw noises, warships. There appeared to be other ASW vessels on the way out to help the DD. Wahoo was at 380 feet
when a closed depth charge exploded near the conning tower, causing damage(see report) to various equipment, injuries to some crew, and flooding. Wahoo settled at 402 feet due to flooding while water was pumped. However, the DD appeared to lose contact after this.
The DD and other ASW vessels hunted for several hours. After flooding was stopped and water pumped out, Wahoo was able to ease back to 375, then 350 feet and head away to NE away from Bougainville. At 1300, Wahoo secured from GQ and silent running, remained surfaced until 1900 hours, when surfaced into a dark moonless night and heavy seas.
Upon surfacing, proceeding through the channel between Bougainville and Choisuelil and south of Fauro Island and the Shortlands. Submerged at dawn December 8 to monitor traffic in area. Only observed patrol planes and a patrolling destroyer. Surfaced after dark and proceeding up West Coast of Bogainville.
Gun Action No.1
9 December 1942
Entered Empress Augusta Bay during the night off Cape Torokina where observed several enemy Daihatsu type barges. Ordered General Quarters-Battle Surface-Gun Action at 0600 and closed in. Opened from just 2,500 yards. The barges caught fire and burned quickly. Received light machine gun fire from one, which was quickly silenced. Five barges total were destroyed.
Secured from GQ and exited the area at high speed as dawn broke into day.
At 0640, SD had high speed contacts, just into deeper waters, ordered a dive. Two ZEKE/ZERO fighters closed in fast and strafed the Wahoo as she submerged, causing minor damage topside. After submerging, explosions were heard but not close. At 0800, ASW vessels interfered area but did not locate Wahoo, which was now clear into the Solomon Sea.
Wahoo patrolled the waters between Rabaul and Buka for new few days an weeks, observing Cape St. George, New Ireland and its lighthouse on 16 December, avoiding a patrolling destroyer in area, turning south towards "half way" point between Buka and Rabaul for remainder of patrol, which proved uneventful in area. At 0000 on 20 December, Wahoo set course for Brisbane, where would terminate patrol as Wahoo has been transferred from COMSUBPAC to Task Force 72 for the time being.
The passage from the Solomon Sea to Brisbane, via Louisiade Archipelago and the Coral Sea was uneventful aside from a few curious RAAF bombers and patrol vessels. Wahoo arrived Brisbane at 1000 hours on 28 December 1942, ending her second war patrol.
Patrol totals:
One Takao Class heavy cruiser-heavily damaged
One heavy Takao class heavy cruiser- lightly damaged
One Sendai Class light cruiser heavily- damaged.
Torpedo performance continued to be poor with premature explosions, duds,
and apparent depth control issues.
Later in patrol a message was received warning torpedoes run deep, to set shallow accordingly, this was after both torpedo attacks of this patrol. Noted for next patrol.

PROLOGUE
Arrived Brisbane, Australia 28 December 1942 from second war patrol. Following shore leave, repairs, and preparations for third war patrol, ready for sea 16 January 1943.
Operating method would differ this patrol as would remained surfaced as much as possible, namely in open ocean areas, to properly utilize the SJ radar in day time
NARRATIVE
1943:
17 January
0730-
Departed Brisbane, Australia with orders to; (1) Reconnoiter Wewak, New Guinea ;(2) Conduct patrols in the Palau-New Guinea shipping lanes. (3) Conduct sonar tests and torpedo fire control drills with Patterson DD 392 in Moreton Bay, Australia on 17 January prior to departing Brisbane area for patrol.
0800, sighted Patterson, exchanged recognition signals and followed through minefield. Conducted trim dive, then went to GQ for torpedo fire control drills submerged with bow and stern tubes.
0930 -Surfaced. Conducted Torpedo Fire Control Drills on the surface with the TBT.
1200- Concluded fire control exercises. Continued sighting exercises through afternoon. Remained under escort of Patterson.
1800-Patterson broke off and retired to Brisbane. Set course for Wewak, New Guinea per operation order via Coral Sea, Louisiade Archipelago/Jomard Pass, Solomon Sea, Vitiaz Strait, Brismark Sea route. Wahoo was now on her own.
18 January-
0630-Dawn trim dive.
0645-Surfaced.
0711-SD contact closing fast. RAAF Hudson identified bearing 165 at 9,000 yards. Plane appeared to be making aggressive action, possibly believing Wahoo was enemy submarine, Wahoo submerged. No explosions.
0800-Surfaced, continued for Louisiade Archipelago/Jomard Pass.
18-23 January-
The next three days were uneventful, followed normal routine.
Entered the Jomard Pass just after midnight on 20 January, and cleared Vitiaz Strait on 22 January. Passage was routine avoided SD contacts and a patrol vessel in Vitiaz Strait set course for Wewak, arriving in area later on 23 January.
0400-
Due to patrols and unknown obstacles, it was decided to penetrate Victoria Bay at Wewak from he North and west via a passage between Kairiru Island, Mushu Island and the Guinea mainland. Wahoo submerged 3 NM North of Kairiru Island and began submerged approach to enter if possible and reconnoiter Victoria Bay-Wewak area.
0530- Observed two Chidori type ASW vessels at anchor off Mushu Island. Wahoo passed quietly with little room under the keel in the pass. Fathometer was not utilized to avoid announcing presence.
0700-At observation, dawn sunrise observed as Wahoo cleared the narrow pass between New Guinea and Mushu Island. Silhouettes could be seen quit efar int he distance to the east. Wahoo continued on at 3.5 knots speed.
0740-Observed a DD with what appeared to be RO type submarines nested beside. Wahoo was continuing to reconnoiter behind when the DD got underway. At this point it was unsure if Wahoo had been detected, but given little depth to hide in, decided to go on the offensive, with General Quarters called at 0743.
TORPEDO ATTACK NO.1
The DD was identified as a Shiratsuyu Class of about 1700 tons making 14 knots on course 300. Tubes 1,2,3,4 ,5,6 were made ready with out doors on 1,2,3,4 opened. Torpedo depth was set shallow, at minimum depth.
At 0749, fired tubes 1 and 3 from 1000 yards. Torpedo 1 missed ahead as the DD spotted wake, took evasive action, just barely missing her bow. Torpedo three passed astern of the DD and exploded in her wake. The DD momentarily slowed and presented a favorable angle as well as range for a shot and at 0751, fired tubes 3, and 4 from. Observed one pass under the DD, while other missed ahead. The DD made a hard turn, and was now closing on Wahoo with a "bone in her teeth", closing fast from 2500 yards.
Outdoors on tubes 5 and 6 were opened and Wahoo commenced a high speed turn into the destroyer until was presenting a zero degree AOB. At 0759, at a range 600 yards, Tubes 5 and 6 were fired and Wahoo went "deep" to the bottom with a hard turn to port to avoid being directly under the DD when with perfect timing, the second torpedo (Tube No 6) hit the DD, setting off a loud, continuous, and massive series of explosions!
0801, back at periscope depth, observed the DD 800 yards astern and opening, on fire amidships and on stern, down by the bow with angle, props broaching the surface of the water. Life rafts in water along with debris were also observed. From 0804-0808, observed the stern rise from the water with props in air before entire vessel settled into shallow waters of the bay.
Wahoo was already on a exit course to the west at a steady 6 knots during this time with bow tubes being reloaded.
0825-Explosions above, close. No vessels around, likely aircraft from nearby aerodrome responding to the scene.
0830-More explosions from aerial bombs.
0837-More explosions from aerial bombs. Close, mild damage incurred (See damage report)
0845-Fast props detected on sound.
0901-Observed a small patrol boat making best speed towards area. Observed low flying "PETE" floatplane, apparently tracking Wahoo from above.
0925-The small PC was closing Wahoo quickly. Rigged for Depth Charge, Silent running, and called General Quarters. No pinging, believe PB had sound gear only but in the still shallow water, Wahoo was easy to track. PB made several DC runs, a couple were close, but no damage taken. PB seem to lose contact after runs.
0937-Two sets of fast screws from NNW detected. These were the Chidori's spotted earlier in the morning, responding to the area.
1000-According to charts, reached deeper waters, was able to go to 125 feet.
Chidoris and PB laid massive barages of depth charges astern about 5000 yards as well.
1020-One set of fast screws raced on Wahoo (now at 150 ft) from astern and began pinging. Unsure if detected or aircraft spotted. What is assumed to be the Chidori laid impressive pattern down, causing some damage on first and second runs, but soon lost contact.(see damage report).Other PB's joined astern and laid more depth charges as Wahoo escaped, reaching deeper waters.
By 1300, Wahoo has cleared Victoria Bay, secured from GQ and Depth Charge, maintained silent running until 1500.
1630-Came to periscope depth. The outline of the New Guinea coast was slightly visible in the afternoon haze. Went to 100 feet and maintained until nightfall, surfacing at 1900 hours.
1900-After surfacing, began repairs and set course for Palau-Wewak shipping lanes NNE of New Guinea per operation order.
25 January-
Quiet day, dove to avoid a few air contacts.
26 January-
0756-SJ Radar made contact at 11,000 yards. Multiple green lines dancing on the A scope. Wahoo set intercept course with smoke visible on bearing in morning sun.
TORPEDO ATTACK NO.2
0805-General Quarters-Torpedo-Submerged. Contacts appeared to be four merchants on course 125, likely en route to Wewak. No escort escort vessel.
Ahead of the convoy by 830, Wahoo submerged for attack, closing from 7000 yards off the projected track of the convoy. Approach made at 4 kts, then slowed to 2.
At 0855-Vessels identified as a AK Tamyo Maru, AK Hakusika Maru, AP Hakai Maru, and AO Buzyun Maru in two columns. Course 130 at 9 kts. Out doors on all bow tubes opened, depth set to 8 ft. Skies were clear, seas had a moderate chop.
At 0902-Fired tubes 1,2,3 at Tamyo Maru, and Tubes 4,5,6 at the large troopship (AP) Hakai Maru leading the starboard column. Torpedoes ran true, with two hitting the Tamyo Maru, and all three hitting the Hakai Maru, setting both afire. The torpedo that missed the Tamyo Maru, barreled on and hit the tanker (AO) Buzyun Maru by sheer luck as it manuever to avoid collision with theother vessels., which exploded a massive fireball and began to sink, obviously loaded with volatile fuel. The 8800 ton Hakusika Maru turned away at best speed, firing its aft mounted deck gun in Wahoo's direction.
At 0908, Hakai Maru Troopship sunk. Many boats and rafts with troops filled the waters. At 0915 Tamyo Maru sunk, followed by tanker Buzyun Maru at 0925.After torpedoes were reloaded, secured from GQ and surfaced once Hakusika Maru was over Horizon. Surfaced at 1025 hours to pursue the last vessel.
SD radar contacts , likely aircraft dispatched to distress calls made the end around difficult for a time but by 1530 hours, Wahoo was ahead of the target and submerged directly ahead, then turned off the track for a shot with stern tubes.
TORPEDO ATTACK NO.3
At 1604, target was on course 155 at 10 kts when tubes 7,8,9,10 were fired from range of 850 yards using two degree spread on the TDC dial. Two hit amidships and exploded, one hit the bow and was another DUD. The fourth hit just ahead of the stern, causing an explosion and fire.
The Hakusika Maru lost way and quickly began taking a down angle by the stern, slipping beneath the waves at 1617 hours. Wahoo surfaced at 1620, secured GQ and headed NNW at high speed until nightfall. Several SD contacts were made but none closed.
27 January-4 February were quiet with occasional air contacts, none detected Wahoo as she patrolled the open ocean between Palau and New Guinea.
On 5 February, reconnoiter Fais Island but did not shell the industrial area there due to shore batteries and consistent aerial coverage. Returned to patrol area.
TORPEDO ATTACK NO. 4
9 February 1943
At 2335 hours, SJ radar made multiple contacts at 10500 yards. Closed to five merchant vessels with one DD ahead.
Wahoo shadowed convoy, waiting for the quarter moon to set and enable night surface attack as conditions were excellent. After a zig and gaining position, Wahoo went to General Quarters-Torpedo-Surface, for her first night surface attack.
Approaching from the starboard, Wahoo readied her four remaining torpedoes in bow tubes 3,4,5,6 and closed to 2,500 yards off starboard side, which had three AK's in column. Two were fired at the lead and middle AK's each at 0140.
Wahoo began it's turn to port to bring the stern tubes to bear when three torpedoes prematurely exploded in quick succession. Alerted, star shells went up and tracer fire from the merchants machine guns began streaking over Wahoo, stern tubes were ordered ready and out doors opened. Suddenly, a large explosion roared across the sea, and a fire plume visible. The last torpedo while missed the intended target, went on and hit another AK in the second column.
Wahoo was now running flank speed away with the DD closing to the area pursuing, but it stopped near spot where Wahoo was sighted, convinced we submerged, circled and dropped depth charges. Wahoo slowed, then maneuvered to end around, closed outer doors on stern tubes and and closed
the scattering merchants.
The AK hit by the errant torpedo was now dead in water and listing. Location was marked for follow up attack as Wahoo passed it some 6,000 yards to port in pursuit of the vessels.
TORPEDO ATTACK NO. 5
9 February (continued)
At 0325 Wahoo, returned to General Quarters and closed on the loosely reformed, zigging convoy. The destroyer had since rejoined ahead, making wild sweeps.
Wahoo backed down and at 0331, fired four torpedoes at a large AK, all four hit and target was obliterated, sinking in less than ten minutes. The destroyer had Wahoo in it sights this time, closing in at over 30 knots, firing, Wahoo submerged with shell splashes around, went to 300 feet, rigged for depth charge and silent running.
The DD barreled over and let a pattern of depth charges go as Wahoo passed 220 feet, which shook the boat violently, causing air lines to leak in conning town and control room.
The DD proved an aggressive hunter, staying on Wahoo until 0800 hours, when it left the area, assuming to catch up with remaining charges. Wahoo cautiously came to scope depth, then surfaced on the all clear and returned to the location of the merchant damaged in the initial attack on the convoy.
SJ soon had a long contact. Upon closing submerged, revealed the AK Biyo Maru, dead in water and listing, large hole in her starboard side just ahead of the amidships area. Out of torpedoes, the order for Battle Surface-Gun Action was given.
GUN ACTION NO.1
9 February
Surfaced 7,000 yards to starboard of target and opened fire with the 3 inch 50 caliber deck gun. First four rounds missed, but gunners found the marked and scored 5 hits in a row, as Wahoo closed. The stricken vessel dd not return fire with its deck guns. After 50 rounds expended and 33 observed hits, the stricken vessels slipped beneath the waves at 1002 hours.
1010-
Wahoo secured from GQ and set course for Pearl Harbor as had been transferred back to COMSUBPAC. Submerged repeatedly during the day to avoid air contacts.
10 February-19 February
Transited to Pearl Harbor. Passage was routine aside from dives to avoid enemy aircraft.
19 February-
1330- Arrived Submarine Base Pearl Harbor, Territory Hawaii. Terminated patrol.

PROLOGUE
Returned from THIRD War Patrol to Submarine Base Pearl Harbor, T.H.,
on 19 February 1943. Relief crew took over for maintenance and other tasks crew enjoyed leave. Repairs to damage sustained last patrol were conducted at the Submarine Base. In addition, the the 3 inch deck gun was replaced with a 4" deck gun forward , along with a twin 20mm AA gun mount was installed in aft conning tower. Some routine personnel transfers were conducted during this period as well, notably LT (jg) R.R. Smith was detached and Ensign T.G. Forest reported aboard. Twenty-four MK 14 torpedoes were taken aboard on 1-2 March, and Wahoo was declared ready for patrol on 2 March.

24 March:
0000-Entered assigned Area (Area 6) off Kii Suido and began patrol. Per success of last patrol, decided if possible to remain surfaced as much as possible in area, although could prove difficult when is close proximity to the coast and entrance to the Kii Suido due to it's importance and said to be heavily patrolled.
0830-SD contact 10,500 yards, closing fast. Wahoo submerged. At periscope depth, observed a H6K MAVIS patrol flying boat.
0935-Surfaced.
1230-SD contact. Submerged.

TORPEDO ATTACK NO.1
1700-SJ contact bearing 050 13,300 yards. Ordered intercept course.
1708-Spotted smoke bearing 345 degrees. Lone contact appeared to be merchant on course 255.
1730-Submerged directly ahead of target at 12000 yards.
1735-General Quarters-Torpedo-Submerged. Depth 100 feet
1750- Sound had strong heavy long prop closing.
1800-Periscope depth. Very large merchant observed on course 045 (appears to have zigged) at 12 knots. Went to 90 feet, increased speed to Ahead full to close target, counter the zig.
1830- In position off project track of AK identified tentatively as HEIAN MARU (1,800 tons). This unusually large AK had deck guns mounted atop her superstructure, vehicles and cargo on deck. Unbelievable the vessel was unescorted, perhaps due to rendezvous with local escort.
1840-Out doors on Tubes 1,2,3,4,5,6 made ready.
1845-On observation, vessel had zigged toward, putting Wahoo too close for bow shot. Ordered turn to bring stern to bear for shot for stern tubes. Closed outer doors on bow tubes.
1855-Vessel at 6,000 yards, closing. Sterns tubes made ready. Torpedo depth set for 10 feet.
1903-Maru in ideal AOB of 90, range 900 yards. Fired Tubes 7,8,9, 10.
1903:25-Torpedo 1 hit the target amidships, blowing a visible hole in starboard side and fire amidships raged.
Torpedo 2 hit but failed to detonate-DUD.
Torpedo 3 prematurely exploded just before hitting the target.
Torpedo 4 was observed passing directly below the stern and then exploded just after. The explosion as close enough it seemed to affect the enemy vessel, now slowed, listing slightly to the starboard.
The topside deck gunners observed Wahoo's scope now at just 500 yards as turned to bring bow tubes to bear for snap shot and opened fire. Wahoo dropped scope and went to 90 feet, as the loud thump of the freighter was heard as it passed above us. Back at periscope depth, the vessel was making 6 knots, apparently heading back towards mainland with a decent list and visible smoke from the fire.
Preparing for the end around, stern tubes were reloaded while observed the vessel steam over the horizon out of visual range as dusk began to settle in.
2000-Surfaced for end around. Enemy vessel on SJ bearing 010 at 11,000 yards.
2015-New SJ contact bearing 073 10500 yards. Closing fast.
2028-Contact identified as a DD. Likely responding to distress call from target, appeared to closing Wahoo. Turned in opposite direct at flank speed. Enemy DD did not appear to have contact with Wahoo.
2030-During this interim, lost SJ contact with the AK.
2100-Regained SJ contact with freighter at 10,000 yards bearing 035. The DD was now at 150 at 8,000 yards, Visible in the late dusk haze.
2110-DD observed in high speed run NNE closing on wounded freighter.
2114-New SJ contact bearing 280 11,000 yards.
Assessment of situation indicated to local patrols closing on area to cover the damaged HEIAN MARU as it limped back towards port. Secured from GQ temporarily as moved to gain firing position down the quarter moon. The light fog haze helped obscure Wahoo.
TORPEDO ATTACK NO.1-CONTINUED
2325-General Quarters-Torpedo-Surface.
The AK was not making 8 knots with slight list, no longer zigging on course 030 8000 yards astern. One DD was within 4,000 yards off to the starboard. A second, smaller DD or DE type vessel was running a very loose portside rear flank escort and gave Wahoo an opportunity.
2325-2340- Forced to abort twice as DD's movements put Wahoo too close.
At 2342- the starboard side DD dropped and made a wide sweep heading away. Wahoo maneuvered into position on the starboard side, already holed by a torpedo and set up for a shot with bow tubes.
2350-Wahoo was 2,400 yards off starboard side of the AK, with Tubes 1,2,3,4,5,6 ready, outer doors open. Torpedoes set in increments for 5ft, 10ft, 5 ft.
2352-Fired Tubes 1,2,3 from 2,250 yards. Maintain slight port rudder and backing at 1/3 to keep bow pointing in case needed another shot.
2353:31: Fired Tubes 1,2,3 as "individual shots" with near firing bearing for each fish. One torpedo aimed amidships, one bow, one stern.
During this time, the starboard DD was observed at very high rate of speed closing back to station after its sweep.
2354:01-Torpedo 1 impacted the target amidships, causing large explosion, blowing boilers out. Torpedo 2 followed and hit just behind the bow starting a fire. Torpedo 3 hit the stern, causing fire and visible damage.
Wahoo, already turning at high speed came under machine gun and dck gun fire from the freighter. Star shells from both DD's illuminated the sky. Both seemed ot have a fix on Wahoo and were rushing towards Wahoo as she made 21 knots heading 345.
2355: Several large explosions rocked the HEIAN MARU, which went silent, and began listing heavily to starboard, dead in water. The second DD spotted Wahoo and was firing her deck guns but appeared to be older DD which could not close distance .
2357:01 HEIN MARU 11,800 tons sunk. Observed capsizing and slipping beneath waves.
2358: The original DD contact had a bead on Wahoo and was flaying down increasingly accurate fire with shell splashes. Wahoo submerged to avoid, heading for 300 feet, rigged for silent running and depth charge.
25 March:
0002-Pinging as DD closed from stern to starboard, as Wahoo leveled at 300 feet turning to port.
0003-DD above, splashes heard.
0004-A well laid pattern exploded above, but one depth was at or below Wahoo's depth, rocking the boat, causing high pressure airline leaks, broken glass, piping leaks. Wahoo ordered to 325 feet. During the explosions, the high speed "burst" at ahead full for 35 second was made.
0006: The second DD arrived and pinged, making an ineffective run as charges appeared to be set well above.
Wahoo eased to 350 feet and gave the two the slip, as for the next 4 hours, appeared to circle the area, depth charging some poor marine life mistaken as the submarine they were hunting.
0430-Lost sound contact with enemy vessels. Likely playing "possum."
0530-Periscope depth, all clear. Came to radar depth at 43 feet. SJ contacts at 8000 yards and 9,000 yards astern.
0540-Went to 100 feet, secured GQ, and depth charge. Maintained silent running. Decided to open distance before making the noise of surfacing.
0630-Radar depth. One contact 14,000 yards. Secured Silent running.
0635-Surfaced. Ordered reload, proceeded away from coast to rest crew and make repairs as needed.
0730-SD contacts 10,900 yards , closing. Wahoo submerged to 200 feet.
Throughout the day when came to periscope depth for checks, numerous patrol planes sighted, hornets nest stirred in area. Decided to move further out to sea for a few days to let the alert die down.
2100-Surfaced. Recharge batteries.
26-29 March:
Patrolled open ocean areas, no contacts aside from diving for SD contacts.
30 March:
0811: Cruising on surface after morning trim dive.SD contact at 9,000 yards, simultaneously spotted by lookouts as low flying twin engine bomber at high speed (G4M BETTY) DIVE!
0812: As Wahoo passed 125 feet, series of loud explosions rocked the boat. Piping, Lines, leaked, glass broken. Minor damage reported on port prop shaft.
0818-Leveled off 300 feet. Set opposite course last observed.
1000- All clear, surfaced.
1115- SD Contact 11,000 yards. Submerged.
1130- While below at 150 feet, sound detected pop noises. Set intercept course, came to scope depth. Spotted smoke of two merchant vessels on apparent course for Japan.
1135- Surfaced for high speed intercept run, keeping distance at 13,000 yards. Sea state had turned rough with clear skies and high winds, making the advance slower.
1150- SD contact 12,000 yards closing. Submerged to avoid.
1205-Surfaced. Continued pursuit course.
TORPEDO ATTACK NO.2
1400-General Quarters-Torpedo Submerged.
Targets appeared to be small AK and small AO in column, steaming 315 degrees at 10 knts.
1430-Submerged ahead of targets, 4000 yards to port off projected track.
1445-Observation-Targets tentatively identified as AO HARUNA MARU of 1,550 tons and AK TAIHOSAN MARU of 1,850 tons, sailing in column with AK leading.
1450-Readied tubes 3,4,5,6, out doors opened. Tubes 1,2, on standby. Torpedo depth set for 7 feet.
1455-Range 1000 yards form targets off port side. Fired Tubes 3,4 at AO, fired tubes 5,6, at AK. Point of aim both both was amidships with 5 second firing intervals.
1556: Torpedo 1 hit the tanker but failed to explode-DUD! Torpedo 2 hit just forward of her aft stack, causing an explosion and fire, but no the hoped for massive blast, as tanker appeared to be empty of volatile fuel or oil. Also, it is believed the torpedo's magnetic detonator exploded beneath, not the contact exploder as no visible hole was punch in the vessel. The AO was however left dead in water and clearly taking on water in the stern.
Torpedo 3 hit the AK amidships and blew a large blow under her stack, leaving her on fire and dead in water. Torpedo 4 hit the stern, setting off a large chain reaction explosion, obliterating the vessel as masts and stack collapsed. The burning hulk went adrift, taking on water.
1559-Observing both vessels, the tanker was now down by the stern with the bow lifting out of the water slightly. The flaming hulk of the AK was adrift but sinking.
1602-TAIHOSAN MARU (1,850 tons) sunk!
1605-The small tanker was stubbornly hanging out. I did not wish to use another torpedo on this target. The heavy seas were swamping the mortally wounded tanker as well.
1615-A G4M BETTY twin engine bomber was spotted via periscope bearing 090, circling the area at lower altitudes. Went to 80 feet.
1625-Periscope depth, the stubborn little tanker was now down by stern with her bow in the air, out of the water. The BETTY was not sighted but presumed in area.
1635-A series of explosions occurred in the AO, which then quickly slipped beneath the waves. AO HARUNA MARU (1,550 tons) sunk!
1650-Wahoo at 200 feet, heading away from scene. Secured General Quarters, reloaded torpedo tubes.
2200-Surfaced, began closing Japanese coast to patrol off Kii Suido.
1 April:
0600-Trim Dive
0615-Surfaced
0700-Submerged 10 NM SSW of Cape Shionomisaki Lighthouse. Set course 270 to patrol just outside the entrance to the Kii Channel.
0800-Sound contact of warship.
0815-Observed a PC type vessel sweeping area. Moved to avoid. Lost contact at 0831.
The day consisted of observations every fifteen minutes, cruising at 80 feet in between for sound contacts. The rough seas made SJ sweeps at radar depth difficult, close to impossible.
TORPEDO ATTACK NO.3
1231-Sound contacts identified as merchants and warships bearing 200, closing.
1240-Periscope depth, spotted smoke bearing 205 degrees Estimated range 7 miles closing. Moved to intercept.
1245-General Quarters-Torpedo-Submerged.
1300-Small convoy entering the Kii Suido. Four mid sized AK, one escort, possibly submarine chase or PC type.
1315-Convoy zigged. Wahoo turned, went to 150 feet, used a run at standard speed to reposition for stern shot.
1330-Convoy observed course 300 at 8.5 knots. Composition identified as
One Etorofu type escort vessel/sub chaser with
four AK in two columns. Port Column: KOTO MARU, JOKUJA MARU
Starboard Column: RYUSEI MARU, ANZAN MARU.
1340- Outer doors on tubes 7,8,9,10 open. Depth set for 6 and 10 feet in intervals.
1345- Range from starboard column: 1000 yards. Fired two fish at RYUSEI MARU, two at ANZAN MARU at 5 second intervals.
Torpedoes 1 and 2 ran true, exploding beneath RYUSEI via magnetic detonator .
Torpedoes 3 slammed into ANZAN MARU just aft of amidships and into the stern. The rudder and prop were visibly blow off and flew through the air from the stern hit. Both vessels were on fire, dead in water.
As the escort was out of position sweeping at time of attack, Wahoo went into high speed turn to bring bow tubes to bear as the KOTO MARU was heading TOWARDS Wahoo, either inadvertently or to ram.
Tubes 5,6, were made ready, outer doors open, set to 6 feet as came about, found the AK coming on wit a ZERO AOB. However, it was too close for torpedo to arm and Wahoo went to 90 feet to avoid ramming and the merchant passed above.
1355- Back at scope depth could see the two crippled AK's roughly 1500 yards astern.
1356-RYUSEI MARU sunk!
1357- Escort vessel sighted, closing fast. 3000 yards bearing 300. Ordered 300 feet, rigged for depth charge and silent running.
As passed 80 feet, sound reported worship closing high speed.
1359-Escort passed above as Wahoo passed 230 feet. Dropped a pattern of charges which shook the boat.
After several more pinging runs and drops, the escort lost contact. Sound conditions of thermal layer at 275 feet and the heavy seas were not ideal for ASW.
1420-ANZAN MARU sunk following large explosions (based on sound, bearing and later observation of oil field at last location, given credit for sinking.)
1440-Escort passed above again pinging, dropped a pattern ahead to port, did not shake boat. Explosions only.
Turned to course 180 to leave area. Secured General Quarters. Maintained depth charge and silent running.
2000-Periscope depth. All clear visual and sound. Secured Silent Running and depth charge. Return 100 feet.
2130-Surfaced. Set course to patrol off Cape Muroto.
2 April:
0404-Fourteen miles off Cape Muroto, sighted widely spaced group of 7 fishing vessels. Sea condition had calmed to light chop.
GUN ACTION NO.1
0406-Battle Surface-Gun Action.
0410-All guns manned and ready. Began closing a loose column of
fishing vessels.
0415-Wahoo turned into the column, to run along side and open fire broadsides with deck gun and twin 20mm.
0417-Opened fire on lead with 4 inch deck gun and twin 20 mm. Four inch gun aimed for waterline. The twin 20 mm used to rake the topside.
As passed by at 6 knots, the lead boat exploded. Target switched to next boat in the column from 2000 yards, which quickly burned, masts and sails collapsing. The third opened fire with machine guns as did others, a few rounds hit the Wahoo but no damage. The twin 20mm proved highly effective suppressing the return fire. The first five boats were quickly left burning wrecks, sinking. The remaining two were racing in opposite direction, sporadically firing machine guns in Wahoo's direction. From 3000 yards, three successive hits a near miss left boat number six adrift and silenced her gunners. As Wahoo sped by, one more four inch round finished the job, along with 20mm fire.
The final boat was dead ahead and firing it's machine guns. A few errant rounds hit the bridge and deck gun areas, causing minor wounds to Executive Officer, LT G.H. Jackson, USN, and CGM P.L. Holt, USN. However, the boat was quickly left a flaming wreck after hits by the 4 inch gun and finished off by the 20mm.By 0450, all fishing boats had sunk. Each boat believed to be about 300-500 tons.
0500-Secured General Quarters. Departed area at high speed.
0630-Trim dive
0645-Surface. Continued west to the extreme limits of Assigned area, approaching Area 7.
0745-Submerged in Tosa Bay, 40 NM NNE of Cape Ashizuri.
Throughout the morning in the now very calm waters, conducted surface patrols under air patrols forced submergence. Periscope observations and SJ radar sweeps at depth were conducted.
TORPEDO ATTACK NO.4
1130-Wahoo was on course 000, approximately 10 miles East of Cape Okitsu
when observed distance smoke bearing 020. Sound check revealed distant props. A quick rise to radar depth confirmed a lone contact. Wahoo set course for intercept.
1200-General Quarters-Torpedo Submerged.
1205-Contact appeared to be large AK on WSW course at 11 knots within 5 miles of the coastline.
1215-Contact zigged toward coast.
1217- Wahoo surfaced to pull ahead and track with SJ radar.
1230-Submerged 10 NM off Cape Kanmuri to attack as vessel rounded the cape.
1255-Vessel identified as SURABAYA MARU of 5,186 tons. Cargo and trucks visible on deck. Tubes 1,2,3,4,5,6 ere made ready, with depth set for 8 feet.
1304-Just after rounding the cape and resuming course speed. Wahoo fired
three torpedoes from a range of 850 yards. Each torpedo aimed as individual shot on new bearing, aimed at middle of target, stern, and bow.
All three torpedoes hit and exploded as designed, crippling the AK.
Wahoo turned to head out to sea to the SE, observing the sinking vessel.
Air and then surface patrols arrived on scene, but no contact with Wahoo was made.
1330-Secured General Quarters
1400-SURABAYA MARU (5500 tons) sunk. 5 NM South of Cape Kanmuri.
1800-Surfaced.
2000-Submerged to avoid SD contact
2030-Surfaced.
3-6 April:
Wahoo was now back in the open sea lanes 100-150 miles South of Kii Suido bettwen Capes Shionomisaki. These days were uneventful aside from SD contacts.
7 April:
TORPEDO ATTACK NO.5
0122-SJ contacts bearing 047 Range 12500 yards. Wahoo turned onto intercept course on what was a dark, moonless night, ideal for night surface attack.
0150-Convoy sighted! General Quarters-Torpedo-Surface.
Target was determined to be a Southbound Convoy, possibly out of Tokyo.
A contact report had been received 48 hours ago from another submarine but out of Wahoo's range at the time.
Convoy appeared to be seven ships and two escorts, larger and better protected than previous convoys encountered.
Convoy was tracked on a roughly SSW course at 8 knots and Wahoo moved in to position, looking to attack the column with larger ships on the port side.
0220-Wahoo in position off project track to port. Tubes 1,2,3,4,5,6 made ready. Eight torpedoes remaining, all in bow. Outer doors opened.
0225-Wahoo 3,000 yards off port column, closing. Column had one mid sized AK leading a large AK with a large AO trailing.
0230-Wahoo 2,400 yards. Fired three torpedoes at the large AK and
three at the large AO. All aimed as individual shots with TBT, one to MOT, one to stern, one to bow.
Torpedoes 1,2,3,4,5 ran true. However, Torpedo number 6 went into a CIRCULAR RUN, necessitating quick evasive action. The torpedo just barely missed Wahoo's stern and exploded in our wake. Stern torpedo tubes, the port propeller shaft, and compartment suffered damage from the explosion.
This explosion and the Wahoo's maneuvering, alerted the convoy Star shells illuminated the skies and Wahoo came under fire as it moved away with speed reduced to 18-19 knots due to damaged prop shaft. The escorts were barreling in. During this time, three torpedoes appeared to prematurely explode, but one found it's home in the tanker, which apparently was loaded with volatile fuel and erupted in a massive explosion, burning from bow to stern and began to settle in the water quickly. The tanker was subsequently identified as 10,000 ton NIPPON MARU class tanker.
The escorts, identified as a Fubuki DD and a Momi DD, stopped and dropped depth charges, believing Wahoo had submerged. Meanwhile, Wahoo was maneuvering back as her last two torpedoes were loaded into tubes 1 and 2.
After several attempts to close two different vessels but being unable to attack due to wild maneuvering. Wahoo secured from GQ and ended around, until the convoy settled down.
0400-Lost SJ contact.
0445-Regained SJ contact bearing 320 range 13000 yards. Convoy had apparently made zig to NNW during interim.
0450-Went to General Quarters-Torpedo-Surface, in an attempt get in a surface attack before dawn. However, an unexpected zig put Wahoo out of position. Secured and pulled ahead for down submerged attack as light conditions were no longer favorable.
TORPEDO ATTACK NO. 6
0700-General Quarters-Torpedo-Submerged.
Submerged 11.000 yards ahead of convoy and closed. Made a "u turn" off track to bring bow tubes to bear. The leading DD, a Fubuki class skirted by at 2400 yards ahead as Wahoo closed the convoy.
0740-Outer doors open on tubes 1,2, with final two torpedoes set to 10 ft depth.
0745-Targeted large AK KENYO MARU (8,150 tons) in starboard column with rising son of east in background to illuminate the targets.
0748-Fired tubes 1 and 2 at middle of target, at five second intervals from 900 yards range.
0749-Both torpedoes observed and heard impacting target, both failed to detonate-DUDS!.
The AK spotted the scope and opened fire and DD's immediately closed in, as the calm seas would no doubt aid them. Wahoo went down emergency for 300 feet, rigged for silent running and depth charge.
0754-Wahoo leveled off at 300 fee as a DD pinged away and made a run. Depth charges exploded above and below, shaking the boat.
0757-Second DD made a run and dropped a pattern, which exploded above, except for one very close charge above the forward torpedo room, which caused moderate damage, including flooding(See damage report).
0758-Damage Control Party assigned to stop flooding in forward torpedo room. The enemy destroyers continued a run after run dropping charges. Wahoo took a down angle due to flooding and eventually leveled off at 380 feet.
0808-Damage Control Party reported flooding under control. Pumping out water.
0811- Pattern of close charges above, conning tower damaged (see damage report).
0812-1104- Enemy destroyers continued hunting and dropping charges as Wahoo hid at 375 feet. Periods of quiet and searching followed by closing in an dropping. Wahoo with a damage port propeller shaft, having to fight flooding, and pump water was no doubt noisy and easier to follow in the calm seas. Subs appeared to lose contact at 1104 hours. As Wahoo eased off to the South at 375 feet.
1200-Secured General Quarters. Maintained silent running.
1400-Heard one DD in area, searching, dropping charges.

P. L. Holt, Chief Gunners Mate, USN. Injured by machine gun fire during Gun Action No. 1. Conditioned worsened post action. Detached at Midway, flown to Pearl Harbor for further care.
REMARKS:
Busy, productive patrol. Area 6 is a busy area in the Japanese home islands which is well protected by air and sea patrols. Enemy ASW efforts seemed improved in comparison with past encounters.
For the second time (first on 3rd patrol), Wahoo utilized the night surface attack, which is preferred to submerged when possible.

1105-General Quarters-Torpedo-Submerged
1110-Convoy at 7,000 yards. Lead escort is Akikaze DD, sweeping. Wahoo turned off to starboard, looped back and closing convoy from starboard side.
1122-Convoy is in two columns; Starboard column is Large AK, Large AP, Large AK. Port Column is Large AK, Large AP, Large AK. Lead escort is Akikaze DD, rear escort appears to be a smaller DD or frigate type vessel.
1125-Tubes 1,2,3,4,5,6 made ready, out doors opened.
1128- Fired three torpedoes at the large HIKAWA MARU as individual shots at amidships, forward, and aft. Fired three torpedoes at AK SANRAKU MARU aimed amidships, forward, and aft from range of 1,100 yards from starboard column.
1129- Three torpedoes hit the AP, three large holes visible in hull, vessel quickly took a list to starboard. One torpedo prematurely exploded just yards from the SANRAKU MARU, a second hit and was a dud. The third hit, and set off a massive series of explosions, leaving the vessel on fire. The vessel was apparently loaded with volatile cargo, likely ammunition. The flaming hulk began to quickly settle.
Both escorts quickly honed on Wahoo's trailed as rigged for silent running, depth charge, and headed for 300 feet. Wahoo hid under a thermal layer at 225 feet, which for a time seemed to confuse the enemy, as patterns were way off.
1151-DD (Akikaze) seemed to get a strong bead on Wahoo and closed in fast Pinging. Wahoo descended as it appeared the thermal layer was no longer a factor, to 300 feet.
1152-A close pattern by the Akikaze violently shook the Wahoo. Damage reported in Control Room and Forward Torpedo. Most serious of which was flooding in control room. Damage Control Party dispatched.(see damage report)
1155-Damage Control party stopped flooding in control room.
1200-Wahoo at 375 feet. Very intense depth charge pattern laid above, to side and below.
1202-Second escort dropped close pattern, above, to the port, and below. Intense explosions. Damage reported to aft batteries, capacity reduced to 75 percent. Hydraulic pump disabled, steering and depth controls grew sluggish.
1205-Wahoo slipped to 395 feet while water pumped from control room. Slugging depth controls made depth keeping difficult.
1214-Both escorts dropped intense, large patterns within less than one minute. Most were above, but close. Boat rocked violently, pressure lines and piping leaks throughout boat.
1215-1235-Multiple depth charge attacks.
1236- One escort heard leaving area fast, likely to cover the convoy while other (believed to the frigate type vessel) remained in area dropping depth charges close by, while Wahoo bounced between 385-396 feet.
1247-1340-Endured numerous depth charge attacks. One close pattern at 1320 caused flooding in conning tower and forward torpedo room.Wahoo sunk to 420 feet at 1334. Damage Control party dispatched.
1341-Enemy went quiet. Believe enemy lost contact and thought Wahoo destroyed.
1350-Flooding under control in all compartments.
1500-Enemy heard leaving area at speed bearing 270.
1525-Wahoo came to 300 feet, eased to 200, then 100.
1600-Periscope depth, all clear. SJ radar sweep at radar depth, lone SJ contact bearing 200. Secured silent running and general quarters. Surfaced on pursuit course while priority repairs conducted and torpedoes reloaded.
1601-1801-Able to maintain SJ contact on what was believed to be the
trailing escort.
1802-SJ contact regained with convoy at bearing 340, range 14,141 yards. Opted to continue end around while conducted repairs, would attempted night surface attack.

0000-Sent position and contact report. Wahoo now in Southwest corner of assigned patrol area.
0130-Convoy zigged, countered to maintain position after high speed run.
0155-Moonset. Sounded General Quarters-Torpedo-Surface.
0200-Ahead of convoy, turned towards, closing range, to pull off track and open range for attack with stern tubes.
0225-Port column consisting of AK AP AK. Targeted the AP which was quite large, appeared similar to HORAI MARU of 9,000 tons.
0228-Stern tubes 7,8,9,10 made ready, out doors opened. Torpedo depth set to 5 feet.
0233-Fired four torpedoes at HORAI MARU from 2,445 yards.
0234-Second torpedo prematurely detonated seconds before impact, convoy alerted, star shells visible.
0235-Three torpedoes slammed into the troopship, the second caused a large explosion and fireball, visible gaping hole amidships visible.
Wahoo sped away from the scene as the lead DD raced to where Wahoo fired from but did not appear to have visual on Wahoo.
0240-Reload of stern tubes commenced.
0245-DD began depth charge in area from where torpedoes were fired, assuming Wahoo had submerged.
0300-Wahoo swooped forward of two AK's fleeing westward, constant helming at 7 knots.
0315-Stern tubes reloaded.
0320-Approached the two westward freighters. The frigate type escort
was 3,500 yards astern.
0322-HORAI MARU sunk!
0328-Tubes 1,2,3,4 made ready, outer doors open. Torpedo depth set to 6 ft.
0331-2,000 yards off starboard side of AK identified as SAMUYAMA MARU 4,037 tons. As the ship began its zig to starboard, fired tubes 3 and 4.
0332-Two torpedoes hit the freighter amidships and just forward of amidships as its turn completed. Vessel crippled and burning.
The second AK about 1,500 yards after to port of MOMOYAMA MARU,
opened fire at Wahoo with its machine guns, then a aft mounted deck gun as it returned. The trailing escort fired star shells in Wahoo's direction and picked up speed, heading for Wahoo. Wahoo turned away at flank speed. Stern tubes on standby in case needed to torpedo the escort.
0350-The escort was pursuing and firing, with distant shell splashes but could not close the range to overtake Wahoo.
0355-Turned off the track and escort lost visual, kept chasing down original heading, as Wahoo looped back to head for the second AK, tentatively identified as the BOKUJA MARU of 7390 tons.
0401-While closing the AK, the Akikaze DD was barreling on scene at high speed. Turned stern towards as it passed at 4,000 yards.
TORPEDO ATTACK NO.5
0431, now on port side of BOKUJA MARU, turned off track to present stern tubes and backed down. Outer doors opened on tubes 7,8,9,10.
Target was constant helming along course 100 at 8 knots.
0433-From 2100 yards, fired last four stern torpedoes at BOKUJA MARU as it reached the swing to port, turning into the spread of fish.
During torpedo run, Wahoo was spotted by the freighter, which opened fire as Wahoo speed away.
0434-Two torpedoes impacted the freighter, which was likely loaded with ammunition judging by the massive series of explosions, fireworks that followed, breaking the vessel in two halves from amidships area, which later sunk. The other two torpedoes missed.
As Wahoo raced from the scene, the escorts swarmed to the area. Akikaze DD seemed to spot Wahoo and closed fast firing, overtaking Wahoo, so submerged, rigged for depth charge and silent running.
0437-The DD ran above us pinging but went too far ahead and dropped.
0440-Wahoo leveled off at 325 feet.
0445-The DD and escort which arrived soon after dropped in area, pinged but never made solid contact on Wahoo as it rested under thermal layer.
0540 -Periscope depth, all clear. Secured and surfaced.
0543-On surface had SJ contacts astern at 13,000 yards, one stationary at 8,000 yards at 300. This was likely the damaged AK. As would not be able to close the convoy for another night surface attack due to time, raced back to administer the coup de grace to the crippled AK.
GUN ACTION NO 2.
0600-SAMUYAMA MARU type AK in sight, dead in water with a list at 5,000 yards. Called Battle Surface-Gun Action. Four inch gun and twin 20mm manned.
Closed to 3,500 yards.
0610-Opened fire with 4 inch gun. Scoring four hits in a row, which started fires and punched holes at waterline. The vessel did not return fire.
0620-After expended 35 four inch rounds and 200 20mm rounds, caused fire.
0631-SAMUYAMA MARU (4037 tons) sunk!
0633-Secured General Quarters. Set pursuit course of convoy to end around, conduct submerged attack with last two bow torpedoes before
convoy exited are and fuel necessitated a return to base.
0634-0900-End around.
0934-Regained SJ contact with reconstituted convoy. Sea state increased with wind to a nice chop.
1248-General Quarters-Torpedo Submerged
1250-Submerged ahead of convoy, which was now formed into a single column with Akikaze DD ahead and the frigate type escort astern.
1314-In position off starboard side of convoy. Outer doors opened. Last two torpedoes set to 9 feet. Target vessel identified as KENJO MARU (7627 tons).
1318-800 yards from target, fired final two torpedoes. Both torpedoes were observed striking the target, but failed to detonate-DUDS!
The KENJO MARU opened fire at Wahoo's scope, as the DD and frigate raced toward Wahoo's location. Wahoo rigged for depth charge and silent running, headed for 300 feet.
1320-At 214 feet, thermal layer located, Wahoo held station there. This aided , along with the choppy seas in evading the enemy as their initial attacks were not effective.
1341-DD closing fast pinging, appeared to have a bead on Wahoo. Wahoo went ahead full as passed overhead and to 250 feet. Close explosions rocked boat. Minor damage report (piping, airlines)
1345-Second escort passed over dropped pattern. Wahoo now at 300 feet.
Explosions above, not close. Wahoo wen to 350 feet.
1350-2130-
One escort believed to be the Akikaze DD hounded Wahoo through the afternoon, into the evening. Dropping patterns, gaining, losing, then regaining contact until 2130, when it went "silent" for last time, sitting and listening. Wahoo at 375 feet slipped away heading east.
2340-DD was heard on sound moving away at high speed, likely to catch up with convoy.
5 July:
0000-Periscope depth. All clear. Secured and surfaced.
0010-Set course for Pearl Harbor to terminate patrol.
6-19 July:
En route Pearl Harbor, uneventful other than dodging SD contacts.
Sighted PBY at 1200 on 19 July. Exchanged recognition signals.
20 July-
0845-Rendezvosed with escort (PC).
0905-Entered channel.
0930-Arrived Submarine Base Pearl Harbor, T.H., terminated war patrol.

CONCLUSION
Successful, productive but challenging patrol. Enemy ASW by escorting vessels has increased in effectiveness compared to earlier patrols. The area
patrolled as well as surrounding appear to be suspected high traffic area for
troops and equipment being sent sent south to support Japanese operations in New Guinea and the Solomons via Palau/Truk.
Troopships were loaded down enemy troops as many were spotted in water after sinking. Several of the cargo vessels were apparently loaded with ammunition, resulting in devastating explosions when torpedoed.
Reliability of Mark 14 torpedo continues to be an issue with numerous failures such as 'duds' upon impact and premature explosions. Torpedoes are also suspected to run deeper than set.

CONCLUSION
A disappointing patrol due to issues with new electric torpedoes. Believe torpedoes suffer guidance issues in form of gyro failures and depth keeping issues. One torpedo made circular run after launching, forcing Wahoo to go deep. While the wakeless feature is a clear advantage, especially if miss as
enemy forces are not alerted generally. Most disappointing of all, the torpedo failures caused a miss on a carrier clearly in sights, accurately plotted.
Assigned area is prime hunting grounds and another try is desired, perhaps with a mixed of torpedoes.

PROLOGUE
Returned to Submarine Base Pearl Harbor, T.H., on 22 September 1943. Relief crew took over for refit and crew departed for leave.
During refit period Wahoo was equipped with a new SJ-1 surfaced search radar
with a PPI scope in conning tower. New SD-1 Air search radar installed as well.
Informed of advancements in remedies to MK 14 torpedo issues. The depth keeping issue had been remedied and since July, magnetic features had been deactivated. However, 'dud' issues persisted due to faulty firing pins and new firing pins were installed and more manufactured. However, for upcoming patrol Wahoo would again be provided with a load MK 18 electric torpedoes.
On 12 October, 24 MK 18-1 torpedoes were loaded aboard and Wahoo was ready for sea.
NARRATIVE
Per COMSUBPAC Operation Order 80-43, Wahoo was assigned to proceed via La Perouse Strait into Area 10 (Sea of Japan) and conduct offensive operations there south of the Noto Peninsula/Toyoma Bay.

Starboard column;
Five vessels: AK KINOPOSAN MARU, RYUSEI MARU,
MADRAS MARU, AO AKATSUKI MARU, AK ARISAN MARU.
Port Column;
Four Vessels: AK KANAGA MARU, AK ZINBU MARU, AP SAKITO MARU,
AK KENJO MARU
1418-Tubes 1,2,3,4,5,6 made ready, outer doors opened. Torpedo
depth set for 10 feet.
1420:31: Firing Observation;
Fired tubes 4,5,6 at AK ARISAN MARU (7.827 tons)
Range: 1,350 yards
AOB: 72
Fired Tubes 1,2,3 at AO AKATSUKI MARU (11,800 tons)
Range: 1,050 yards
AOB: 90 S
1420:43: Just 12 seconds after tube No.6 was fired and confirmed running normal, a massive series of very closed explosions rocked Wahoo close aboard from port, starboard, and forward. Lights went out temporarily, light bulb, glass broken, piping leaked steady stream of water in conning tower, air pressure lines busted, the attack scope went "dark", could no longer see target just fired at. Conning tower was taking in water.
Before could catch breath, a second series of explosions on both sides amidships and aft occurred, lights went off then back on. Apparently, Wahoo had been spotted by aircraft (two actually) and bombed while at periscope depth, just after firing.
Damage reports soon came in quickly. Reports flooding in all compartments,
with more serious in forward torpedo and aft torpedo room. Damage Control parties were dispatched. Wahoo began sinking. (See Damage Report)
1423: Flooding in conning tower, control room, and forward torpedo room
under control. Flooding in aft torpedo and engines room was being battled.
1424: Torpedo impact! Torpedo impact/explosion heard on bearing of convoy. Too late to hit intended target. All other torpedoes would miss target. Likely
due to Wahoo being spotted from the air during torpedo run, giving ships time to evade.
1425. Wahoo at depth 155 feet, a series of explosions above, likely more dropped by planes.
1426-Pinging began, escorts closing in. Wahoo at 200, trouble maintained depth. Water being pumped.
1427-Forward torpedo room reported flooding under control, but suffered heavy flooding. Aft torpedo room heavily flooded, forcing speed to maintain control. Controls sluggish due to hydraulic pump damage. Trim pumps damaged also.
1431-Destroyer passed above, dropped pattern of charges. Wahoo
was at depth of 268 feet.
1432: Charges exploded somewhat close. Shook boat.
1434: Aft torpedo room flooding under control. Pumping out water.
1435 While increasing speed to compensate for flooding, noticed Wahoo was not making normal speed at Ahead flank. This was found to be due to
damaged (beyond repair) starboard prop shaft.
Wahoo continued to sink, wit crew fighting to control her as water pumped.
Sinking beyond thermal lawyer, and heavy seas, no idea sonar conditions likely helped make Wahoo a difficult target despite the noise made during the battle to save the boat.
1450-Wahoo at 400 ft., sinking. After falling below 400 feet, the escorts appeared to have lost Wahoo or thought she was lost. Battery power was draining fast using constant speed to prevent rapid sinking.
1500-Wahoo at 500 feet. Some control restored as water pumped out, trim pump repaired, but still sinking. After torpedo room was of most concern.
1505-The escorts apparently heard Wahoo and were soon nearby, pinging, and dropping depth charges. Thankfully none were close, except one.
1510-Wahoo at 550 feet.

CONCLUSION
Area 4 remains a busy, target rich environment that is heavily patrolled by sea and air force of the enemy. A stroke of bad luck Wahoo was spotted from the air.
Enemy convoys are now more organized, with more ships, and escorts than in the past. Air Cover at times as Wahoo found out.
The improved Mk 14 torpedoes Wahoo did get to fire worked perfectly with none of the issues of the past to my knowledge.

PROLOGUE
Returned to Submarine Base Pearl Harbor from War Patrol EIGHT on 31 January 1944. After survey, entered Naval Yard to repair damage from air attack. Crew sent ashore for R and R.
At Naval Yard, in addition to starboard prop shaft being replaced, as well as other damage repaired, the forward twin 20mm gun was replaced with a single 40mm Bofors mount and Wahoo was painted in the Measure 32 paint scheme. All repairs and refit were completed by 1 March 1944.
On 2 March, twenty-four MK 23 torpedoes were loaded aboard along with provisions and fuel. Wahoo was ready for sea and set to depart on patrol the following day.
NARRATIVE
Per COMSUBPAC Operation Order 31-44, Wahoo was assigned to proceed to the area of Yap Island and (1) Reconnoiter assigned points of island and general area; (2) Conduct anti-shipping operations in the area; (3) Assume station no later than 0000 hours on 30 March for Lifeguard Assignment in support of Fast Carrier Task Force air strikes of 30 March-1 April on Palaus, Yap, and Woleai. The strike on Yap was scheduled for day of 31 March.

loaded with fuel as it erupted after first hit, the second proving
redundant. Next, torpedoes hit the IZIMI MARU, which
lost way and listed immediately. Leading AK GOGIMA MARU turned
hard to port, evading one torpedo which passed just ahead of its bow,
scraping past. However, the second torpedo slammed into the
starboard corner of the stern, with prop and rudder blowing off visibly
blown off and sent airborne, landing in the sea. A large hole was also

the tube, turned to port to pull ahead and away, watching
the lead escort closely as well as the port flank escort astern, now
racing back to regain his position.
0129-Three out of four MK 23 torpedoes fired hit the AP, which seemed to
absorbed them well, but then slowed. Smoke was seen coming from
the amidships area.
Moments later torpedo hit the AO as it was beginning its turn to
starboard upon witnessing the torpedo's hit the KOTOBUKI MARU
ahead, but this proved futile as both torpedoes slammed into the large
AO, which was apparently full of fuel as it exploded in a magnificent
fashion with bright flashes and loud rumble of sound which carried
across the sea. The AO was a burning hulk and quickly lost its way,
the AP was slowed but underway with a list to port.
130- Illuminated by star shells, Wahoo came under heavy gunfire from the
escorts and auxiliary cruiser, with shell splashes observed ahead, astern
and to port and starboard. The port and starboard Otori's were also
closing.

(used external camera to observed. The DD spotted the oncoming torpedo just in time, turned hard and torpedo passed just below props. If had magnetic detonator, would have been a hit. DD then correctly course and passed over the bow of Wahoo, dropping a pattern."
0136-Torpedo missed! DC splashes. Wahoo at 350 feet.
0137-Large pattern of explosions, boat shaken badly. Minor
damage (see damage report)
0138-Otori (port) arrived on scene, slowed, listening.
0140-Otori began pinging from bearing 170.
0145-Otori closed in from 200, passed above and dropped pattern of DC's.
0146-Pattern above and to port.
0147- AO OSAKA MARU 14,812 tons sunk following a series of explosions.
0148-Otori (port, the second Otori hung out with the Aux Cruiser and the damaged AP) passed aster about 500 yards, dropped pattern.
0151-Akizuki DD closed from 035.Wahoo eased to 375 feet just after ceased
pinging.
0152- A large powerful pattern of explosions above, one at Wahoo's level,
exploded close. Damage reported (see damage report). Flooding
reported in Forward Engine Room. Damage Control Party dispatched.
0155- Flooding in Forward engine room under control. Wahoo
at 388 ft. Pumping out water.
0201-Otori closed in and dropped a pattern, did not explode close.
0205-Akizuki and Otori passed above and off port side within seconds of on
another, many splashes heard.
0206-Large, impressive pattern of explosions. Wahoo used this change to go
ahead full for one minute and to starboard, using the disturbances in
water to escape. Pipes and airlines in conning tower and control room
sprung leaks. Wahoo at depth of 396 ft.
0208-Lost sound contact with both escorts. Appears had lost Wahoo and
were listening.
0214-One contact, believed to be the Otori was heard leaving
the area at high speed, likely to rejoin the remainder of the convoy.
The DD remained quiet, believed to be sitting above to port-stern
somewhere at 3,000-4,000 yards.
0231-Sound contact; warship bearing 337,medium range, closing very fast!
0233-Pinging, appeared the Akizuki was back on the trail of Wahoo.
0235-DD passed above, splashes heard. Wahoo went ahead flank to port,
descended to 385 feet.
0234-Explosions, above, one close caused leaks in conning tower to
spring once again. (Piping and air pressure lines. Lights flickered.
Boat shaken.
0235-0340-The DD made multiple other runs, but no close.
Stopped and listened at 0340, as Wahoo lost contact again.
0349-Sound reported DD leaving area at high speed bearing 044.
0400-Periscope Depth. Clear. Secured silent running.
0402-Surfaced.
0404-SJ contacts on scope. Two were roughly in position where the
large troopship was last seen. One appeared stationary, other nearby
was moving. Thus, it was believed this was the stricken transport dead
water being guarded by an escort.
One pip, visually identified as he Akizuki was closest but head away at
high speed.
Two distant pips at bearing 333, range 15,650 yards was believed to be
the Auxiliary Cruiser and the third escort.
0408-Wahoo underway towards the stricken troopship. SJ has contact
at bearing 000 at 8,780 yards. The silhouette of the large ship was
visible from the bridge. Wahoo decided to head astern of the ship to
come around the starboard side and avoid the Otori, patrolling
back and forth along the port side, blocking an approach and shot.
0409-Akizuki slowed and began dropping depth charges.
0410-The damaged AP was observed underway at 5 knots with heavy list to port. Wahoo travelled up the starboard side at 7,000 yards and pulled ahead
to fire at angel and hit the damage side of vessel with stern tubes.
TORPEDO ATTACK NO.3A
0418-Wahoo turned to bring stern tubes to bear.
0421-Tubes 7.8.9.10 made ready to fire. Outer doors opened
Torpedo depth set to 5 feet, shallow to flood water line.
0428-Fired tubes 7,8. Ranges 3,100 yards. Torpedoes were fired with AOB of
25 for a "glancing" blow as could not get into position for port side
shot due to escort presence.
0430-With 10 seconds in torpedo run left, the Otori escort spotted Wahoo,
began closing at high speed, firing star shells and its deck gun. Wahoo
raced off and prepare for a "Down the Throat" shot.
The torpedo impacted the AP one after another, causing fires and
explosions, and the large ship went dead in the water. The Otori which
was passing about 1,000 yards at time of impact, slowed, seemed
stunned by the explosions. May have suffered damage, but seemed too
far away for that. This pause gave Wahoo opportunity to slip away as
Otori lost contact. PPI showed pip believed to the be Akizuki alerted
by the attack, rushing to scene at high speed.
0436-AP KOTOBUKI MARU 18,765 tons sunk!
0438-Otori about 4,500 yards astern, began dropping depth charges,
believing Wahoo submerged.
0447-Akizuki passed astern at 6,550 yards, heading to scene of sinking.
0450-Two torpedoes remaining, laid pursuit course to catch the
auxiliary cruiser, which was off the SJ scope.
0455-Secured GQ to rest crew.
0501-SJ contacts bearing 349 at 16,455 yards. Two pips,
believed to be the cruiser and her escort.
0515-With morning twilight, conditions too bright for surface attack,
would have to try for a submerged attack.
0545-Wahoo was 11,200 yards to starboard of the aux cruiser and her escort
at bearing 270. Two trailing pips (DD and Otori) were on the edge of
scope astern. The auxiliary cruiser was making 12 knots on base
course of 177, zigging along.
0630-Lost SJ contact. Turned to 270 to intercept track.
TORPEDO ATTACK NO.4
0641-Regained SJ contact. One large pip with three pips escorting,
appears the escorts had rejoined to the convoy. The morning
sun was rising. Decided to attack as last chance due to Wahoo fuel
status and target will reach port in early evening.
0650-The convoy zigged to the SSE, Wahoo moved to position where the
dawn sun would be in background to illuminate the scope for attack.
0700- General Quarters-Torpedo-Submerged. Turned heading directly
at convoy now on SJ at 000 11,200 yards.
0701-Submerged. Went to 100 feet.
0710-Periscope depth. Convoy visible. Began turn off track to starboard
once back at 100 feet.
0720-Periscope depth. Convoy on course 155 at 19 knots.
0721-Tubes 9 and 10 made ready. Out doors opened.
Torpedo depth set to 10 feet.
0723-All stop. Lead escort (Akizuki DD) preparing to pass stern.
0725-Luck! Starboard escort left position to sweep! Changed plan for
"glancing" shot from ahead to preferred broadside shot. Speed back
1/3 to close range.
0730- Ahead 1/3
0732-Firing observation; Range 1,250 yards. Fired torpedoes
aimed amidships at 5 second intervals.
0733-As scope was rising, the auxiliary cruiser's alarm was audible
as had spotted the torpedoes. As scope broached water,
observed the cruiser turning hard to starboard and speeding up.
The first torpedo's wake was observed running down her
starboard side, likely scraping paint and passed on into her
baffles. However, the second torpedo slammed into the cruiser just
behind the bridge. A large delayed explosion occurred
some ten seconds later as the cruiser slowed, smoking and a fire
behind the bridge area visible.
0733-Pinging from the Akizuki began almost immediately as it was
barreling towards Wahoo. Wahoo was on her way to 300 feet,
rigged for silent running and depth charge.
0734-All three warships heard closing Wahoo's location as she headed
SW.
0735-DD Akizuki pinging.
0736-As the DD roared above, Wahoo went ahead flank and to 325 feet.
0737-Many explosions, some close. Air pressure and waterlines, piping
sprung leaks. Damage reported in forward torpedo, minor flooding,
quickly stopped.
0741-Second escort (believed to be the port Otori) rushed in dropped pattern
as Wahoo leveled at 350 feet.
0745-DD made another run.
0752-The starboard Akizuki made its first run as Wahoo was at 365 feet.
One close charge damaged hydraulic and trim pumps, causing more
lines to spring leaks. Two in control room injured.
0800-0811-All three made successive, intense depth charge runs.
Appeared Wahoo was in a "death circle."
0815- On the next run, Wahoo went to 385 feet at ahead flank for 1.5 minutes, then then all stop, allowed momentum to bring boat through
most of its turn.
0817-Resumed 1/3 speed.
0826-1124-
The persistent DD (believed set to Elite skill) stayed on Wahoo with
intense and accurate depth charges. No catastrophic damage occurred
but damage was accumulating in the boat. Most concerning was the
continued damage to trip and hydraulic pumps and minor episodes of
flooding in all compartments.
One Otori moved on covering the damaged aux cruiser, while the DD
and a second Otori worked over Wahoo.
1125- Wahoo at 390 feet. Lost sound contact with the two
escorts, believing were listening.
1136-The DD suddenly came to life followed by the Otori and
both made quick runs on Wahoo.
1137-The patterns of explosions occurred within less than a one minute of
one another and were intense. Flooding in forward engine room and
minor flooding in conning tower.
1139-Wahoo sunk to 409 feet due to flooding.
1142-Flooding in conning tower under control. Both escorts made dc runs
within one minute of each other again.
1143: The explosions were well above. Thankfully.
1145-Flooding in engine room controlled.
1201-Water pumped out.
1206-DD made a run, one charge close. Wahoo back at 385 feet.
1217The Otori was heard leaving area at high speed. The DD remained
behind, making numerous runs. Some "dry runs" as well.
1218-1827-The DD and Otori continued hounding
Wahoo. For periods of time they would cease, listen, then restart.
None of the runs were close enough as earlier but were close
enough to force Wahoo to remain vigilant.
Wahoo lost sound contact with the DD at 1828. Likely listening.
1900-Secured General Quarters, maintain silent running.
2022- Sound reported warship, moving away very fast, bearing
261.
2300-Periscope Depth. All clear
2303-SJ radar depth, all clear. Secured silent running.
2305-Surfaced. Set course for Pearl Harbor via Johnston Island.
Repairs were underway.
5 May:
0000-Sent status report to COMSUBPAC.
0011-Received reply.
6 May:
Submerged run most of day due to heavy patrol plane presence.
7-9 May:
Uneventful, aside from diving to avoid patrol planes.

0529-Numerous radar emissions detected on the APR-1 Radar Warning
Receiver from bearings 015-040. Set course to track down source of
emissions
0539-SJ contacts bearing 036 18,447 yards.
Multiple pips, formation, and position within
50 NM of estimated location based on contact reports
suggested this was the enemy task force.
Set course to intercept.
0601-In the early pre-dawn sky could make out silhouettes of
BB's with the distinctive Japanese pagoda style masts,
as well as several CV's. The main body was inside
in three long widely spaced columns with a ring of DD's outside.
Task Force was on a base course of 086 at 18 knots.
0605-Sent contact report to COMBSUBPAC.
0613-Received reply from COMBSUBPAC acknowledging
message with permission to attack and would send other units to
attack.
0615-Wahoo racing ahead of task force, barely holding it's 2.5 knots
advantage in speed as choppy seas complicated matters.
0637-Wahoo was 8,000 yards ahead to starboard slightly of Task Force
which judging by the formation was preparing for flight operations.
0645-Task Force zigged hard to port on heading 035. Wahoo raced to counter
but was out of position and task force appeared to increase speed
to 20 knots. After plotting, decided best course to to race ahead to
estimated position tsk force would be after next zig.
0801-Multiple SD contacts 12,000 yards closing. Submerged.
Appears Task Force launched a morning raid as
large formation of carrier based dive and torpedo bombers along with
fighters were observed via periscope bearing 050 on course 095.
0803-Sound check revealed many, distant, heavy, fast props bearing 350-
010. Wahoo set course to 270.
0806-Radar Depth; APR-1 detected numerous radar signals.
0810-SJ contacts bearing 000 13,200 yards. SD contacts also at 11,200
200 yards. Went to 100 feet. Listened to prop noises in distance.
0820-Periscope depth. Many large ships visible on horizon
bearing 000.
0821-Radar depth; APR-1 had signals. SJ radar had the task force
on the scope at 10,150 yards.
Formation was in three large single file columns. Spacing between
columns was about 5,000 yards with 5,000 yards between ships in
columns. A large ring of 30+ DD's circled the columns. Over forty pips
were counted on the PPI scope.
0822-Raised radio antenna (went to 38 feet since cant raise radio antenna in
SH4) and sent contact report. Called General Quarters-Torpedo-
submerged. Ordered 375 feet depth, silent running, and maneuvered
to enter task force through starboard side of convoy screen in a
decent gap between two DD's. The choppy seas would no doubt aid
in this.
0830-Heard DD's pass above as Wahoo was heading towards the plotted
track of the center column.
0837- Periscope depth. Secured silent running.
Spotted a large CV in center column identified as one of the new Taiho
Class of 35,000 tons. 5,000 yards. Other CV's visible astern and in the
far port column, along with BB's, CL, CA. After of Wahoo was
the starboard column with BB, CV, CA, CL as well.
Task Force was on course 086 at speed of 25 knots.
0838-Read all tubes for firing. Opened outer doors on tubes 1,2,3,4,5,6

0841-Raised periscope. As scope went up, ships alarms were audible from
CV and others. Taiho having spotted the incoming torpedoes,
was in a hard turn to port. Two torpedoes hit amidships and one hit just
forward of the stern as she turned, but two forward, one hit aft, and
the final fish missed. Taiho slowed to 14 knots, and smoke visible from
the stern area with a starboard list.
0846-Torpedo impact! Observed a torpedo strike BB in the port column
ahead, appeared to be of Nagato Class. Observed the Taiho moving
along at 13 knots, slight list to starboard.
Sound reported DD closing fast bearing 110. A quick look
showed a Akizuki DD with a zero AOB closing fast. Ordered 300 feet
rigged for silent running and depth charge.
As Wahoo was descending past 90 feet, series of explosions
rocked the boat above, apparently from an aircraft. Boat
shaken, no damage.
0847-Multiple other DD's heard approaching.
0848- Torpedo impact! A torpedo hit an unknown target astern of Wahoo.
0849-Pinging as the Akizuki roared onto the scene. Wahoo at 325 feet.

0859-Charges exploded off to starboard. Wahoo at 375 feet.
0901-A third DD overhead pined and made a run but dropped astern.
0906-Another run by second DD, this pattern was accurate and close
as boat was shaken terribly, more leaks sprung throughout boat.
Forward torpedo and Aft torpedo reported flooding. Damage Control
Party assigned.
0907-Stern torpedo room reported flooding under control.
0910-Forward torpedo room reported flooding under control.
0911-Wahoo sunk to 396 feet. Both compartments had enough flooding
cause depth control issues.
0912-Two DD's made runs right after another. Two large powerful
patterns, all above, boat shaken, but no damage.
0913-1100-DD's made numerous runs, some close, no damage.
1100-Two DD's heard departing area at high speed,
likely to rejoin the task force. One stayed behind and hunted Wahoo.
1131-Lost contact with DD, believe went to "listening". Wahoo at 380 feet.
1136-Heard many depth charge explosions distant. Sound check
revealed a submarine bearing 095. Believe another US sub attacked
task force
(AI subs will hone in on contact reports if within range. As part of the mod I had several US AI subs (submerged and surfaced, at night
in the areas.)
1151-Sound contact; DD closing from 170 very fast, pinging.
1153-DD roared overhead, dropped a pattern, which exploded quite shallow.
1154-The DD continued on at high speed, departing area.
1156-Lost sound contact with submarine.
1205-Periscope Depth; All clear. Secured Silent Running and GQ.
TORPEDO ATTACK NO. 3
1206-Radar Depth-two pips at bearing 120 16,000 yards. Appeared stationary.
1208-Turned to to investigate contacts, went to 90 feet for torpedo reload.
1330-Reload completed.
1340-Periscope depth; Sighted masts at 025.
1346-Sound reported a warship contact ahead medium speed.
1348-Observed a destroyer patrolling in vicinity of warship believed to be
heavy cruiser moving slowly at 2-3 knots on course 088.
1349- Called General Quarters-Torpedo-Submerged.
1400-Observation; Vessel was a damaged Agano Class Light Cruiser
6,652 tons with a large visible hole amidships, listing to port
and making 2.5 knots on course 086. This appeared
to be the unknown vessel hit by a stern torpedo
at 0848. Turned to bring stern tubes to bear. Seas had calmed
considerably.
1407-Tubes 9,10 made ready. Outer doors open.
Torpedo depth set to 8 ft.
1409-Range 950 yards. AOB 87, Fired tube No.10.
1410-Torpedo impacted just directly under the stack which was
followed by an explosion and vessel went dead in water.
Ten seconds later, a series of explosions aft and then forward were set
off. The CL quickly rolled to port and capsized., the bottom of the hull,
props, and rubber visible.
1411-The Asashio Class DD turned about and was heading directly for
Wahoo. A turn was made to line up for a "down the throat" shot.
Outer door on tube 9 was closed. Tubes 7 and 8 were depth to 5 feet
and outer doors opened.
1142-Following series of explosions, Agano Class CL 6,652 tons sunk!
TORPEDO ATTACK NO.4
DD now at 1,500 yards, closing fast, pinging.
1143-DD at 600 yards, fired Tube 7 with AOB of 0, "down the throat".
as DD made a swing to Wahoo's starboard in an attempt attempt to
evade, corrected AOB
35 S, sent near bearing and fired tube 8 from 550 yards. Ordered
ahead flank with a turn to port with 35 degrees of rudder.
The first torpedo missed just astern of the DD, close enough
if had a maganetic detonator it would have set it off. However,
the skilled captain was unable to avoid the second torpedo which
slammed into the DD aft under it's torpedoes,
setting off a magnificent series of explosions, The DD was left a burning
wreck, quickly sinking by the stern.
1144-Asashio Class Destroyer 2,370 tons sunk in just over one minute
after torpedo impact. A PETE floatplane was spotted at 030 closing
fast. Wahoo went into emergency dive and leveled off at 105 feet.
Just after leveling off, a series of explosions shook the boat,

CONCLUSION
A relatively short but busy patrol conducted in support of major operation.
Contact reports were helpful in enabling Wahoo to locate enemy Task Force
and attack, seriously damaging a fleet carrier, sinking a light cruiser, a destroyer and damaging a battleship, as well as sharing credit with sinking
a light carrier.
Enemy escorts were determined, focused and skilled. The Akizuki class
DD remain the most dangerous ASW platform encountered to date. The enemy has apparently deployed an improved type of depth charge, which hs proven more effective as Wahoo has experienced the last couple of patrols.
MK 14 torpedo performance was excellent. The long range/low power feature
proved especially useful on this patrol, allowing Wahoo to crippled
light cruiser, to finish off later and damage a battleship.

(G) AIRCRAFT CONTACTS
Numerous aircraft were detected on SD radar and/or visually sighted
while surfaced and submerged. The most common enemy aircraft
were twin engine bombers, BETTY or NELL's used for patrol. KATE torpedo bombers used for ASW patrol were also sighted. Many, especially twin engine and flying boats such as H6K or H8K were radar equipped
and nighttime air patrols were common to contact.
WAHOO was bombed several times by these aircraft, many of which
were radar equipped. The APR-1 Radar Warning Receiver tended to detect
enemy airborne search radar pulses before SD radar detected the aircraft,
which proved useful. TUNNY suffered heavy damage due to radar equipped
bomber's attack. Enemy airborne ASW certainly has become more competent, especially in the Luzon Straits area.
ATTACKS
Seven Torpedo attacks and three gun actions were conducted on this patrol,
Three large convoys were encountered and attacked. These were well organized and defended with at least one radar equipped escort. Two large tankers were sunk and each were loaded with valuable and volatile oil/fuel as exploded in magnificent fashion upon one torpedo hit. Torpedo performance was excellent overall. One MK 18 electric torpedo suffered an apparent gyro malfunction and tracked in opposite direction supposed to.
All torpedoes were expended on this patrol.
Torpedoes Expended:
MK-24A3: 16
MK 18-1: 8
Total: 24

(I) MINES
Minefields were observed in Balabac and Lombok Straits to control passage of traffic. WAHOO was forced to skirt the northern end of minefield in
Balabac Strait and the eastern side of Lombok Strait. Mines appeared to be large, standard japanese horned anti-ship mines. Passed within about 15 yards (port side of WAHOO) of mines in Balabac Strait.
(J) ANTI-SUBMARINE MEASURES AND EVASION TACTICS
Enemy ASW measures were a bit terrific. Some 55 plane contacts were made, with WAHOO bombed multiple times. Planes in area were radar equipped and flew in day and night. Surface patrols and the deployment of
an ASW Hunter-Killer "Decoy" group in Luzon Straits indicate a shift in IJN ASW tactics.
Convoys were well escorted with lead escort usually having radar and air cover was a constant concern. Deployment of escort vessels such as the MATSU Class DE has been noticed and older vessels appear to have improved
number of depth charges and deployment methods, as well as sound and echo ranging equipment as well as improved depth charges.
Evasion tactics were of WAHOO's standard with high speed runs
to take advantage of diminished sound conditions following
depth charge attacks, with constant rudder on port/or starboard, typically 15-20 degrees to keep from showing a straight track. Combined with depth changes, these tried and true tactics which permit successful escape
from enemy attacks.
(K) MAJOR DEFECTS AND DAMAGE
All damage repaired at sea unless noted otherwise.

(L) RADIO
Radio function was overall excellent on this patrol. Transmission were
made on 8470 cs. and 12705 Kcs. without difficult. As radio function was key
to wolfpack operations, we were thankful.
(M) RADAR
SD-Generally effective; Typical contact range with aircraft
was around 11,000 yards. Often before SD detected, the APR-1 RWR
detected he signals of incoming aircraft and provided a bearing, which SD
does not.
SJ-Performance was excellent, permitting
timely detection and tracking. Convoys were typically detected at 18,000-
20000 yards.
IFF-The unit functioned properly.
APR-1-The Radar Warning Receiver proved a real asset on this patrol, making
WAHOO aware of vessels an aircraft so equipped but
provided a bearing on aircraft that SD does not
and often detecting them before appear on SD, at times SJ.
(N) SOUND CONDITIONS
Sounds conditions varied but were overall satisfactory
performance of JP-1 sound gear was satisfactory. In proper conditions,
was able to heard sounds far beyond the prescribed range. This lead to successful early detection of and eventual sinking of an Akizuki Class
Destroyer.
(O) DENSITY LAYERS
Negative gradients were encountered. Depths noted
are those of the thermal unit which is located 25' above the keel.

(O.) HEALTH, FOOD, AND HABITABILITY
Health was excellent overall. Food supply remained steady
as did relative comfort even with the extended time
required for the journey to Australia as completion of patrol.
The humidity and heat of late summer in regions patrolled were managed
by the equipment aboard.
(P) PERSONNEL
Performance of officers and men left nothing to be desired.
WAHOO has a experienced, dedicated, and competent crew.
The new Executive Officer filled the role well.
The PCO aboard for his tour proved an asset to WAHOO
as an extra officer and certainly will be one to his future command.

Torpedoes-0
Fuel-18,500 gal.
Provisions: 30 days

Limiting Factor of this patrol: Expended all torpedoes. Had three days worth of fuel to remain in area at time of last torpedo expended.
(U) REMARKS
1. Operating as part of Coordinated Attack Group proved useful
in often overwhelming enemy defenses to prevent multiple sinking
one coordinated attack as evidenced numerous times on this patrol.
2. Enemy defenses of convoys and in key sea lanes, junction points
have increased in numbers and competency.
3. North bound tankers encountered in area are typically loaded
fuel volatile oil/fuel and require one torpedo to sink, perhaps a second to
ensure. A great aim point is under the aft stack, set to 8019 feet. The
chain reaction explosion is usually enough to sink the vessel.
4. Enemy surface search radar on escorts seemed unable to detect surfaced
submarines at distance or behind or more than 40-50 degrees to the
side, suggesting limited arc of the radar pulse. However, once alerted
the radar did seem to improve the escorts ability to quick locate
submarine on surface and gunfire accuracy.
5. The APR-1 Radar Warning Receiver is a key tool to success.
6. Twenty-three out of twenty-four torpedoes functioned properly,
quite the improvement as just one year prior, this was not the case.

Set torpedo depth for 12 feet. Sent contact report to
COMSUBSOWESPAC.
1858-Lead DD passed 2,000 yards astern as WAHOO
backed astern to close range for firing.
1900-Firing Observation; Range 1,550 yds. Fired
tubes 7,8,9,10 at the lead CA. Aimed
on individual firing bearings two amidships, one under
one under first turret forward, and one under turret aft.
1902- All four torpedoes hit the cruiser. First two hit a few feet apart
1904 amidships, which slowed the CA and left a visible hole. The third
torpedo hit under the forward turret, apparently hitting the magazine
and set off a massive explosions, followed by numerous secondary
explosions, nearly blowing off the bow, leaving the ship on fire
from bow toot just aft amidships followed by the fourth torpedo
impact forward of the stern. These events left the CA listing heavily to
port as well. Meanwhile, WAHOO was turning hard to starboard to
bring bow tubes to bear.
1905-The second Takao CA made hard evasive maneuver just missing her
stricken sister by about thirty feet.
1906-DD's were now heading right for WAHOO's location. Without
possibility of a shot in time on the other CA which was had turned
away, rigged for silent running, depth charge, and ordered 300 feet,
emergency.
1907-Pinging. DD closing from 280, turned hard port into to minimized profile to beam.
1908-Thermal layer at 185 feet, leveled off just below.
(Temperature Gradient No.1)
1909-DD passed above, splashes audible. Wahoo at depth of 275 feet
1911 . Several explosions above, not close, but boat shaken.
1913-Second DD closed, pinging. Dropped pattern, above and astern.
1916
1919- One very large, massive explosion, followed by several
1921 smaller, but large secondary explosions from
bearing of the cruiser. Sounds of vessel sinking,
breaking up clearly audible. Takao Class CA sunk!
1922-Both DD's closed in pinging and dropped patterns within
1926 two minutes of one another. Most charges were not closed,
but one landed fairly close to port, shaking boat badly.
1927-Descended to 325 feet.
1932- A relentless series of depth charge runs by the DD's
2000 occurred for nearly thirty minutes, several close charges
caused some minor damage. WAHOO descended to 375 ft.
2001-One DD left area at high speed
2015 likely to rejoin the other CA. The second DD
continued hunting, making a few "dry runs"
before going quiet at 2016. Sound lost contact with the DD.

0700-Came to radar depth as fog made difficult
to visually plot at distance.
0715-Due to heavy screen close to share,
Mk 14 torpedoes set to low power
to fire from outside screen at long range.
With weather, torpedoes unlikely to be
spotted.
0730-Tubes 1,2,3,4,5,6 made read. Outer doors opened.
Torpedoes set to 12 feet.
0736- Through the fog, intermittently observed large AP in middle of convoy
to use as firing bearing bearing with a healthy spread.
0747-Fired tubes 1,2,3,4,5,6 at 8 second intervals with
spread from 4,825 yards.
0751-Torpedo impact heard/observed. Could see see flames and smoke
in the fog.
0752-Torpedo impact heard/observed, fire and smoke visible.
0753-Escorts searching. WAHOO turned to head to deeper waters
0802 at high speed. Several escorts dropping depth charges astern
at distance.
0803-Moving at 8 knots on course 093 at depth 0f 100 feet when suddenly
multiple large, close explosions occurred above to port and starboard
shaking the boat, causing damage. Sea and airlines in conning tower
sprung leaks, damage reported throughout boat. Apparently
we had been bombed by an aircraft. (see damage report)
0804-Flooding reported in control room, crew quarters, and
forward engine room. Damage control party assigned.
0805-Flooding controlled in control room.
Sound reported escorts astern closing. Depth
of 115 feet.
0806-A series of explosions forward, above to port.
Forward torpedo room reported damage;
minor flooding.
(believe the MAD-Magnetic Anomaly Detection, well the simulated,
in TMO was at play as aircraft would not have normally spotted
in the sea and weather conditions)
0807-Forward engine room flooding controlled.
Crew quarters flooding controlled.
Pumping out water.
0808-Forward torpedo room flooding controlled.
While all flooding controlled, depth keeping
was difficult due to flooding in several
compartments , with forward
dive planes transmission disabled as well as trim pump
damaged.
0809-Two escorts heard closing at high speed
0813 from 175.. Twenty five degrees on right rudder
provided gradual turn off track. Depth now 154 feet,
near bottom in these parts.
0815-Pinging, escort closing bearing 133, closing.
0819-Detected thermal layer at 161 ft, leveled off just below.
(Temperature Gradient No.3)
0821-First escort astern; heard launchers fired off followed by
0825 many splashes, then more splashes likely from stern racks.
Large pattern of explosions but only one was close enough for concern,
believe rough seas and thermal layer through escort off.
Second escort made another run just after, deployed charges
too far astern. Used opportunity to go ahead flank
and turn.
0831-Random explosions to starboard, close. Likely another
aircraft. Close explosions caused more leaks in air and sea lines to
spring which had previously been repaired.
0835-Both escorts honed in on us, made runs one minute apart.
0844 Depth was now 200 feet. Many large explosions-
a few close ones. More damage reported, most serious was forward
battery damage.
0850-Depth; 225 feet, approximately 15-20 ft. off bottom.
0852-Numerous explosions in vicinity, from DC's and presumed planes,
0937 but appeared they had lost contact.
0950-Lost sound contact.
1000-Secured GQ.
1200-Periscope depth; Clear, visibility limited. Secured silent running.

26 NM South of Dao Ly Son Island.
2130-Convoy heading for the strait west of the island
2140 with island to east of convoy and Indochina Coast
to the west. Raced ahead at 18 knots to pass east of
Dao Ly Son out of visual, and ambush convoy
on other side of the strait. Sent contact report
and awaited reply as the end around would
take us into portions of Area B8 (BLACKFIN)
C1 (Gulf of Tonkin-currently vacant, assigned sub en route.)
2141-En route to ambush point at 18 kts.
2359
2 December 1944
0045-Passed 20 NM East of Dao Ly Son Island.
Sea condition improved but a chop remained, overcast with

0120-Surfaced.
0205-Came to all stop at north end of the strait
0342 approximately 15 NM northwest of
Dao Ly Son Island, 10 miles east of Ninh Thuan
on Indochina coast, with bow facing the
strait, observing with radar and visual.
0343-SJ contact bearing 001 at 19,021 yds.
PPI indicated 13 ships and 5 escorts exiting
the strait west of the island.
0350-General Quarters-Torpedo-Surface.
0352-Got underway to maneuvered inside convoy for attack.
Convoy in two long columns with escorts. Formation
did not hold well passing narrow strait.
0355-Detected radar emissions from convoy,
maintained narrow profile to beam.
0400-Convoy moved toward coast, possible
heading to shelter in the bay
at Bai tam Khe Hai.
0413-Observed gap in screen to get inside convoy,
Went ahead flank to get inside.
0426-Dodged a Type C escort that was sweeping east of convoy.
0431-Convoy began turning into the bay
at Bai tam Khe Hai. Due to escorts sweeping
away during turn and presence of radar,
had to rush away and observe.
0435-Ships did not fully enter bay or stop, simply skirted it as
proceeded along the coast at 7 knots. Moved ahead for attack off
Ganh Da ban Than in patch of "deeper" waters along coast.
0445-TORPEDO ATTACK NO.6
0501 Worked convoy, exploiting a gap in the screen astern,
starboard. Dodged two escorts with one astern at just 3,500 yards.
The low visibility proved helpful.
0502-Sighted large AP last in line of the starboard column, worth
four fish. With an AO in the port column , third in line. Decided to fire
two fish at each.
0510-Ordered 40mm guns for defense if needed due to close quarters.
0515-Now parallel at 4,000 yards starboard of AP and pulled ahead.
0523-Began turn to bring bow tubes to bear.
0526 Opened outer doors on tubes 1,2,3,4. Set depth to 8 ft.
0528-Fired tubes 1 and 2 at AO HAKKO MARU (6,839 tons)
0530 in port/inside column from a range of 3,3,50 yds. Fired tubes 3 and 4
at AP OTHA MARU (7,990 tons) from 2,800 yds. All torpedoes
expended. WAHOO made easy turn to be ready to
speed away once torpedoes hit.
0531- Two torpedo impacts on the AO. as expected, the tanker was
loaded with volatile oil/fuel and produced a magnificent explosion
characteristic of tankers. On fire from bow to stern, slowed and
appeared to be sinking as secondary explosions cooked off.
During this time, two torpedoes hit the AP. No fires visible
but smoke from area and did slow with a obvious list to starboard.
0532- GUN ACTION NO.3
WAHOO was by this time moving at flank speed
on a NNE course to exit the screen. As passed a mid sized
AK off port side about 3,000 yards off starboard column,
took some machine gun fire. Ordered 40mm
guns to open fire (love the mod that turns AA guns to surface guns)
which silenced the guns. Hits were scored on the
bridge area, left on fire.
However, this attracted the attention of a nearby escort which
began to close. Low visibility was an asset with overcast and fog,
but dawn was approaching.
0533-APR-1 was picking up radar signals from
180, 210, 092. Ordered "Ahead Emergency" (one special ability I
retained to represent the real time overload on engines such as BARB
used in January 1945 to achieved 23 knots on surface.)
0534-Observed the AP OTHA MARU listing heavily on her side.
0536-Saw a DE type slow searching with spotlight, began dropping depth
charges. However, a second, fast escort continued
pursuing from bearing 180 about about 7,00 yards,
closing, maintain distance. APR-1 detecting radar signals.
0538-AP OTHA MARU 7,990 tons sunk!
0540-Range one escort opening.
0541-Explosions from tanker. AO HAKKO MARU 6,839 tons sunk!
0545-Pursuing escort now 10,000 yds astern, continuing pursuit.
No visual due to fog. Overcast skies.
0555-AIRCRAFT CONTACT NO. 20
GUN ACTION NO.4
0558 APR-1 and SD had simultaneous contact.
Bearing 167, range 11,192 yds. Closing.
Depth sounding; 97 feet below keel.
Ordered AA guns manned. 40mm forward, 40mm aft,
20mm deck.
0559-Aircraft spotted bearing 175 6,000 yards,
altitude 1,000 ft, closing, high speed.
0602-As bomber closed at high speed and low level,
0606 turned Wahoo to present broadside, both 40mm and twin 20mm guns
opened fire with an intense barrage.
The bomber "popped up" to gain altitude for it's dive,
observed fire it its port engine, which spread to wing. Bomber
made dive on WAHOO, which made a feigned turn to starboard,
as bomber committed to dive, went in hard turn to
port, AA guns firing away entire time. Bomber exploded
in the air and crashed into the sea about 150 yards
astern to starboard of WAHOO.
Quickly resumed course as two pips at 9,450 yds were pursuing
WAHOO. Aft 40mm reported low on ammunition.

(C) WEATHER
Weather was overall typical for this time of year in the assigned area.
A few large storm systems proved both an asset and liability, but weather
was mostly pleasant.
(D) TIDAL INFORMATION
Tide tables and pilots not worth bothering with.
Ties were unpredictable overall. The stream
moved swiftly and we could always make headway at two knots.
(E) NAVIGATIONAL AIDS
Lighthouses and coastal navigational lights along Indochina coast were
helpful.

(I) MINES
Mines were spotted in Balabac Strait as well as
Lombok Strait to control flow of traffic.
(J) ANTI-SUBMARINE MEASURES AND EVASION TACTICS
Once again, enemy anti-submarine measures have improved. Convoys regularly have more escorts, often with radar, improved passive and active sonar, along with depth charges that pack a larger punch than once did.
Enemy escort's radar does appear to have mixed results in detection and
tracking as WAHOO was able to penetrate heavy screens on two convoys
surfaced and attack, with devastating results for the enemy.
Most notably improved is enemy ASW by aircraft in terms of detection equipment such as airborne surface search radar, airborne weaponry. On this patrol, an enemy bomber detected the WAHOO while submerged in overcast, fog, and heavy seas while at a depth that visual contact was highly
unlikely. In retrospect, a strange, loud, prolonged "buzzing" sound was heard through the hull several times prior to being obviously detected and bombed.
This happened twice on this patrol and is not viewed as a coincidence, but more a possible new airborne ASW detection system that should be investigated.
Evasive tactics were standard for WAHOO as when submerged, depth changes, high speed runs with constant course changes, exploiting
"dead" sound periods after depth charge explosions and use of thermal layers as well.
Surface evasion consists of maintain when at all possible, low profiles to
enemy escorts and radars, and use of speed. Overload on engines
enabled 22.5 knts surface speed to be reached in a pinch following a successful surface torpedo attack.
Evasion of aircraft contacts consisting of submerging typically,
waiting 15-20 minutes and surfacing after a check at periscope/radar depth.
Exception being when following the final torpedo attack of the patrol,
AA guns were manned and a BETTY bomber was shot down by a
"broadside" of 40mm and 20mm fire.
(K) MAJOR DEFECTS AND DAMAGE
All damage repaired at sea unless otherwise noted.
1.Bow stern planes transmission-Unable to repair at sea.
2.Rudder Transmission
3.Trim Pumps
4.Flooding in Forward Torpedo Room
5.Flooding in Aft Torpedo Room
6.Flooding in Control Room
7.Flooding in Forward Engine Room
8. Forward Batteries
9.Main Induction-Leak
10.JP Sonar-Head-Severely damaged, disabled.
11.Radio Antenna
12.Waterline/Piping leaks
13.High Pressure Airline leaks
14. Assorted fixtures
15. Light bulbs.
(L) RADIO
Radio function was overall excellent on this patrol. Transmission were
made on 8470 cs. and 12705 Kcs. without difficulty.
(M) RADAR
SD-Generally effective; Typical contact range with aircraft
was around 12,000 yards. Once again, the APR-1
often detected the signals of incoming aircraft and provided a bearing, which SD does not.
SJ-Performance was excellent, permitting
timely detection and tracking. Convoys were typically detected at 18,000-
20000 yards.
IFF-The unit functioned properly.
APR-1-The Radar Warning Receiver proved a real asset on this patrol, making
WAHOO aware of vessels an aircraft so equipped.
(N)SOUND CONDITIONS
Sound conditions varied but were satisfactory overall
prior to the JP sonar head being severely damaged and
disabled following air attack.
(O) DENSITY LAYERS
Negative gradients were encountered throughout the patrol.
Records are tabulated below, cards are beinf forwarded to the hydrographic office.
The depths noted are tose of the termal unit which is located 25' above the keel.

(U) REMARKS
Another active, challenging, successful patrol, WAHOO's first
operating out of Fremantle.
North/South Convoys have shifted from open sea lanes to running the
Indochina-China coasts in shallow waters to avoid submarine attack as much as possible. As such, night surface attacks are preferred method, especially
from within the convoy when possible.
As demonstrated in gun action, enemy has also resorted to employing small
coastal boats in convoys for local transport. Gun Actions are more likely
and extra ammunition should be carried.
Enemy aircraft appear to have some new type of detection equipment
which permits detection and tracking of submerged submarines. Wahoo was
spotted in conditions that aircraft would not spot without. Heavy damage suffered as a result.

USS Wahoo SS-238 (Gato Class)
Began Career in August 1942
War Patrol No.13
Overdue and Presumed Lost
USS Wahoo SS-238 departed Fremantle, Australia on 23 January 1945 under
new her new Commanding Officer, LCDR F.W. Walters, U.S.N. and proceeded
to Exmouth Gulf to top off fuel en route to assigned area in the Gulf of Siam
(Thailand), where she docked on 27 January 1945, topped off fuel, provisions, and headed for her area via Lombok Strait, which she transited on the night of 31 January/1 February, turning west to reach area via the Java Sea.
Loss
At 0711 on 3 February, Wahoo surfaced from morning trim dive
and was transiting toward patrol area ont he surface at 15 knots about 50 NM North of Karimunjawa when a low flying aircraft (Kyūshū Q1W Tōkai, Allied codename: LORNA) was detected by the APR-1 Radar Warning Equipment due to its radar emissions, seconds later it was spotted by lookouts at bearing 332, closing at high speed. The SD radar
did not detect the aircraft. A dive was ordered and as the Wahoo was
submerging, the plane dropped depth charges. One scored a direct hit on the deck forward of the conning tower, while other exploded close off port side forward amidships. At the time, the Wahoo was partially submerged at 42 feet in a dive.
The control room, conning tower, and all compartments forward
were severely damaged, flooded with bulkheads destroyed, large hole in the deck from the direct hit, pressure hull compromised, vital equipment such as pumps, batteries etc. were destroyed. Tanks were blown to surface boat but before this could stop the descent, the compromised hull (98 percent damage) collapsed in the shallow depths and was lost near
5°30'48.8"S 110°33'31.6"E in the Java Sea.

TMO BH Update V2.1 (Testing)
Pre-War Career start (June 1941)
USS Sailfish SS-192 (Sargo)
Cavite Naval Base, P.I.
100 difficulty
Cams and Contacts on
Second patrol, assigned to patrol off Indochina in Area B4, particular attention to Cam Rahn Bay area.
On July 27, made contact with the large Saigon Invasion Force by chance and shadowed throughout the day and into the night and into the morning.
I had sound contact with large warships to east, no doubt the supporting carrier force but could not close to contact them.
On the morning July 28 just after dawn, one of the IJN destroyers
began closing at very high speed and opened fire (as part of pre-war mod,
in the lead up to December 7 their neutrality can chance day to day, week to week, month to month, the demonstrate rising tensions, individual incidents
vs a state of war, so always use caution) with deck guns. Submerged the boat and went to General Quarters and prepared to defend against attacks if needed.
Rigged for depth charge, silent running, and went for the bottom at 220 feet. However, found a thermal layer t 171 feet and leveled at 173. Two destroyers arrived on scene hunting, pinging with sonar. A few depth charges
were dropped, a couple close but no damage. After four hours, they gave up. Surfaced and headed to deeper waters searching for the supporting warships offshore but no contact was made.
Throughout following days encountered increasing number of southbound Japanese merchant vessels, non demonstrated hostile intent. Conducted simulated approach and torpedo attacks on a large AK and AP.
On July 15, spotted a destroyer and soon large ships, the silhouettes in night sky appeared that of battleships or heavy cruisers. Pulled ahead and at dawn, spotted two BB and two CA with four DD astern. Submerged for a closer looked in daylight. Approached from west so had the rising sun at dawn illuminating the task force of a Kongo Class BB, Ise Class BB, Myoko Class CA and Tone Class CA. with Akatsuki and Kagero class DD's escorting. The task force was on course 060 at 18 knots. Sailfish was not detected, aided by heavy seas.
Avoided a patrolling DD off Cam Rahn Bay throughout the day and night of 21/22 August. On 1 September, time on station was up, and fuel demanded a return to Cavite. Set course, arrived on September 3 at 1230 pm.

Thanks, hope you will. Ducimus created an excellent mod sometime back and I updated as he's no longer active in community. I've always felt his environmental and graphics were excellent so I have not touched them, other than making the nights darker in order to facilitate historically accurate night surface attacks, also adds a level of difficulty as nights have always been far too light in SH 4 even on moonless night. Allowed to make it so fun things such as night surface attacks from inside large convoys as US subs really did in 1944/1945. Whole new dynamic to the sim.
Let me know if have any questions, etc.
I am working on an update currently but will take some time.

Thanks I appreciate your support and enthusiasm for the mod. Been playing FOTRSU and it’s been great, but so far I haven’t been able to pull off night surface attacks. Fully realized it’s probably a skill issue but… tempted to see what the nights in this mod are like. I’ve been reading through the thread for it but I’m only a few pages in so far.

TMO BH Update V2.1(Testing)
Pre-War Career Star
USS Sailfish SS-192, Asiatic Fleet
Cavite, P.I.
100 difficulty
Contacts and cams on
------------------------------------------------------------------
Departed for on 1 October 1941 patrol off Palau Islands, with orders to monitor the North and West entrances to the main harbor as well as the approaches for twenty five days.
Proceeded through the Philippine Islands, transiting Sibuyan Sea and exiting via the San Bernadino Strait and set course for Palau Islands. Conducted drills throughout the transit. Encountered numerous native craft and U.S.N a gunboat (guarding the strait) en route.
Once in area, a routine of submerging at 0545 each day was established.
Foul weather hampered at eleven days on station. During a trim dive on a foul weather day, prop sounds of merchant vessel were heard but making contact proved not possible due to weather.
On 16 October , a large four engined H6K flying boat was observed via periscope.
On 20 October, while off Palau harbor entrance, a Atami class gunboat was spotted on patrol and was avoided.
During a diving drill on 25 October, noticed dive time had improved,
likely due to experience of the crew gained.
On 1 November, set course for Cavite, this time transit home was via
Surigao Strait, Bohol, Visuyan, Camotes, and Sibuyan Seas. Arrived
at Cavite Naval Base on 4 November 1941.

Great Pre-war career and first war patrol, but file corrupted apparently, lost the career. Risks of moving mods in testing.
4th pre-war patrol, departed on December 4th for exercises in Lingayen Gulf with cruiser Marblehead. Fired "practice" torpedoes (MK 10) and scored "hits" (observed wakes go under ship) with four fired in two attacks. Fired two at escorting Clemson DD and missed. On 8 December received word of war breaking out. Patrolled Luzon Straits as ordered, then responded to invasion reports at Aparri. Attacked task force off Camiguin Island en route, sunk large
trooper of around 9,000 tons (SAKITO MARU). Depth charged severely.
Fired at light cruiser in invasion force off Aparri, suffered prematurely explosions but one torpedo that missed went on to hit a destroyer, sunk it.
Severely depth charged again.
Regained contact with force was it was heading back to Formosa, attacked at dawn. Fired last two torpedoes from 3,000 yards at the Kuma light cruiser. An alert DD spotted the torpedoes, but both still managed to hit the CL, sinking it. Again, severely depth charged (counted 92 total, many close), suffered damage, flooding but survived.

TMO BH Update V2.1(Testing)
Once in area, a routine of submerging at 0545 each day was established...
During a trim dive...
During a diving drill on 25 October, noticed dive time had improved,
likely due to experience of the crew gained.
I have questions.
I always run on the surface until I need to submerge to maximize maneuverability in response to making contact. Maybe there isn't a right and wrong, per se, but is that wrong? Or just historically deviant? How do you patrol and prosecute a contact submerged? I run on the surface at...whatever speed 2 is that I can't think of at the moment in a zig-zag across a patrol area until making a contact. Then I maneuver a bit to get a rough course, then run ahead and lie in wait submerged.
I could google it, but what is a trim dive, exactly, and is there an in-game reason for conducting one outside of historical realism? How do you conduct one in-game? (I mean you, personally. I know how to dive the boat.)
Is the dive time thing real or just part of your narrative? If it's real, is crew development part of the mod or is it in the vanilla game?

Pre-war US submarine doctrine was very cautious, conservative, as SJ(surface) and SD(Air) radar did not exist, so cruising on surface was seen as a unacceptable risk, especially to airborne threats. Submarine was seen as more of scout (fleet type submarine was designed as a scout before supplanted by aircraft in the role generally) and ship that could take advantage of a target of opportunity. Doctrine was so cautious and rigid, spotting of periscope during drills led to
reprimands of CO's, with many trained to fire on sound bearings only (which proved highly inaccurate in war time conditions).
As such, when the war broke out, typically US submarines surfaced around dawn, patrolled submerged for the day, surfaced at night to recharge batteries, replenish air, rest the crew etc. Of course, this limits a submarine to being tantamount to a "slightly mobile minefield." Combined with the issues with MK 14 torpedo from outset, this hampered effectiveness of US submarines from 1941-into 1943.
Air (SD) radar became common in 1942 somewhat negating the constant threat of aircraft, as did SJ (surface) radar later and into 1943 to search for surface vessels, this helped change the doctrine where submarines spent most time on surface patrolling to utilize the SJ radar, lookouts, and maximum speed maneuverability, then submerging for attack. They also employed more aggressive tactics such as "end around" after attacking, for another attack if possible vs the cautious approach.
The night surface attack with torpedoes also became more common in mid 1943-end of war, such as German U Boats did with such success in the Atlantic.
In my mod for TMO....
For historical accuracy, I use tactics used at time of war so in early war, I patrol submerged often. Also out of necessity as was done in real life, as in my mod SD radar is not available until later in December 1941, early January 1942 and aircraft are a real threat. This was done for accuracy and to encourage historical operations by the player.
As in history, 1943 I typically begin operating on surface more, operating more aggressively and as torpedoes become more reliable, one gets an idea of the difference the change in tactics, technology such as radar etc. really made.
A major aspect of my mod for TMO is for first time in SH 4, historically accurate night surface attacks are possible. Stock SH 4 and every mod's environment was far too light at night to permit such tactics. As someone who grew up boating on the gulf and ocean, this frustrated me because it gets pretty dark on the open sea most nights (exceptions of course such as full moon or certain areas) but the nights in TMO are darker, with visual sensors, light factors, convoy spacing, etc painstakingly adjusted and tested (took literally months to get it right, to balance things) so player could pull off attacks way actual US skippers did.. That means not always being detected when closing to the 2500-3000 yards torpedoes were typically fired at on the surface, not always being shot up by deck guns and machine guns
moment spotted. Yet, did not want to make it too easy either.
I have it set where when japanese began running large convoys in late 1943 and into 44/45 player can in many cases get inside the convoy undetected, attack, and flee under fire. Completely changed SH 4 experience.
A trim dive is a short. routine, dive made at dawn and dust typically (maybe noon also, depending) to keep the boat in "diving trim", or the condition to which the boat is prepared for submerging, with ballast and buoyancy tanks properly adjusted. A well trained crew, with proper trim, could dive a Gato Class submarine in less than 40 seconds during the war.
During this dive, can also make a sweep with sound gear and see if can hear distant contacts. Your crew won't report them unless within range of gear which is short, but as in real life, very distant contacts can be heard long before visual or even on SJ radar. Many sinking's have come from these contacts in the sim and during the actual war.
Unfortunately, in SH 4 it does not matter if trim dive or not except it does give the crew experience points and you will see improvement over time as crew racks up experience. One reason I added a pre-war career start in TMO was to give players chance to have some peacetime experience and have not completely green crew, which helps. Same reason I do gunnery, dive drills while en route from say Pearl Harbor to Midway to stop for fuel before proceeding to patrol area.
Keeping with historical operations and for the crew experience, I do a trim dive at dawn, noon, and dusk each day if primarily running on surface, as well as the sound sweep.
OK, cool, that's a lot of good info. Thanks for getting back. Stuff to consider for the next playthrough for sure.

this time...we were in the Luzon Strait, plenty of deep water.
so there she sits...with one fish in her....at some kind of an impossible angle, down at the bow.

here comes our second shot...
https://i.ibb.co/hxCD4JcW/SH4-Img-2025-04-09-16-48-07-163.png
...and our second torpedo as it hits...
https://i.ibb.co/mFHxQRhs/SH4-Img-2025-04-09-16-48-03-619.png
She's done-for.
i could swear that i got a snapshot of her after the second fish hit, but i guess i flubbed the keystroke.
in my defense, the escorts were hopping mad and making flank speed towards us. it was time to di-di-mau. :D
For my sixth patrol I was tasked with patrolling the Java Sea from Perth. Had no trouble or contact getting there and kept to the deep waters at the outset. We had our first contact a week out - a lone LMT had wandered our way on a clear night...
https://i.imgur.com/YOKxJQ9.jpg
Unfortunately for it.
Two days later, we received a report of a large convoy we could intercept, but it would put us in the shallows in broad, clear daylight. We investigated and found a Passenger Liner and an Old Split in the group, and the other four not worth mentioning.
https://i.imgur.com/bx5Dc18.jpg
I'm a sucker for transports, so we committed. The first salvo was almost a complete bust, the fish getting spotted by both targets. Only one of five hit, but it took the transport down.
https://i.imgur.com/dk5dpUH.jpg
You're welcome, ground-pounders.
I kept silent while lining up for a shot on the freighter as it passed, and sent three torpedos into its ass end. The fourth missed and would have gone on to hit the escort, but it turned out of its path.
https://i.imgur.com/1vh23Zt.jpg
Somehow, it didn't slow down much right after that, so I bailed on the convoy and made an end-around. By the time I got set up, they had slowed to 3 kts. I guess the damage had caught up. Anyway, three more hits did the job.
https://i.imgur.com/Zr1hBjx.jpg
At no point were the escorts a threat. I don't think they even attempted to ping. Maybe they don't in the shallows, or it just doesn't work? The seas were pretty rough, I kept the scope down as much as possible, and they never came within 2000 yards, so it would have been really hard to spot me.
Mostly spent and with about 1/3 of a tank of gas left, I decided to head home. On the way we had another radar contact in heavy rain and fog, so I set up for the 90° shot without ID'ing the target.
https://i.imgur.com/mXWPD1d.jpg
https://i.imgur.com/lmwcnvX.jpg
That done, (having never officially completed our patrol - what's the damn radius?), we headed back to Perth. Next up is South China.

Nice job! Enjoyed the report and visuals.
Strange and a bit anti-climatic the escorts did ping etc. A bit anti-climatic. Depends on the mod, the type of hydrophone and sonar equipped, skill level of the escorts, speed level traveling at, settings in sim.cfg as well. Heavy seas definitely helped. Even stock AI is deadly in shallow waters with calm or even moderate seas.

Another day, another failed patrol. This one to patrol the South China Sea just off the SW corner of Borneo. Didn't even make it to station before spending all the forward torps.
We had a couple of single contacts in the Java Strait on the way. The first was in heavy fog so we pulled a 90° and once its fires were visible, finished it off with the deck gun for its first action.
https://i.imgur.com/Ui20tvp.png
https://i.imgur.com/e954Ma3.png
The next we were able to ID and not waste any fish on. I wasn't sure what it was until I saw the lifeboats aft.
https://i.imgur.com/BUAR4EG.jpg
https://i.imgur.com/0vKrxWb.png
26 hours later, still in the Strait, we had a convoy contact the foggy, still morning. I set an investigatory course, scouted the group, and calculated our solutions.
https://i.imgur.com/JSyY7Qy.png
https://i.imgur.com/FXI7I7g.png
They're there, trust me.
https://i.imgur.com/QoGZoJ1.jpg
It turns out the ship on the far side was the wrong one - the LMT was the next nearest in the front row. A fortunate crash after the attack allowed me to correct the mistake.
I gave one away - what was the other target? Which one is the LMT?
https://i.imgur.com/R5bUpRS.jpg
https://i.imgur.com/RihYopj.jpg
https://i.imgur.com/krL6gi8.jpg
It looked like a good launch when the time came.
https://i.imgur.com/w0bRNZa.jpg
The LMT went down when the first torpedo hit! That's a first for me.
https://i.imgur.com/tSJ0IHA.jpg
Only one hit the second target, so I jogged forward into the convoy to put myself between its path and the LMT in the leftmost column. It took some doing and three misses in the fog, but I hit them both, sending the second target down and disabling the LMT.
https://i.imgur.com/ZT8XNMH.jpg
https://i.imgur.com/l1MUs5R.jpg
That's when the escorts descended upon me, and we took damage for the first time in the war. It was harrowing, but the men pulled through with flying colors as we lost the escorts and buttonhooked from the left flank of the convoy to finish off the disabled LMT. By then, I had figured out that it's best to stay on the surface in low viz.
https://i.imgur.com/UdVo37n.jpg
We fell under attack again during our egress but in the end had taken minimal damage.
https://i.imgur.com/nUvDjGA.jpg
After all that, we only had four fish in the aft tubes remaining, so we once again left an unfulfilled patrol on the map.
https://i.imgur.com/J13ZC9o.jpg
We did have another single contact that I let the boys loose on with the cannon on the way back.
https://i.imgur.com/0FlZPxc.jpg
And another rather large but largely disappointing convoy that turned into our path. It was a clear, still night, so four tubes fired, four dodged. One of the escorts snuck up on us as we left the group behind us, but we made for the thermal with little trouble and were off home again.

Thanks!
Another day, another failed patrol. This one to patrol the South China Sea just off the SW corner of Borneo. Didn't even make it to station before spending all the forward torps.
Well, as long as you are sinking ships, not really a failed patrol. :Kaleun_Salute:
More than a few skippers faced same dilemma during war, when encountered enemy targets en route to area. Subs were typically routed carefully but contacting those outside area was inevitable.
One the comes to mind is the USS Jack's 4th patrol, while en route to Luzon Straits (where it attacked the important Take Ichi convoy April 25, 1944 in am impressive feat of long range torpedo shooting), en route Jack encountered troopships in the Molucca Strait area. They fired, attacked and obtained hits if I recall correctly, then proceeded on to area after sending contact report.
Personally, I attack but unless its something like a carrier force, or major convoy etc. I always send a contact report also. If ordered to break contact, then proceed on to area. After I attack, then move on to assigned area. Contact reports get you renown and also in TMO for example, AI subs in area will intercept if in range. While I have wolfpacks in assigned areas for player to operate with. There are AI subs on intervals patrolling various areas player will pass through. Also, in cases where a carrier is nearby, aircraft if in range will come attack. I once sent contact report on a convoy north of Truk in Feb 1944 on convoy fleeing Truk and a surface group centered around Iowa Class BB's (in Truk area) showed up and attacked the convoy lol. Part of the historical forces I added, which happened to in area for Operation Hailstone.
I did report the last convoy as I left and was ordered to break contact (probably because I had literally zero torpedos) and that an asset would be assigned to it. That's a good call, though. Report first.

TMO Update BH V2.1 testing
Gato Class-USS Barb
Testing some changes to SUBRON 50 campaign
2 December 1942 :West of the Bay of Biscay, en route to Rosneath, Scotland after supporting Operation Torch off Safi, Morocco. Cruising on surface at 0441, sim dropped out of x512 TC, a few secs later, explosion followed by damage reports, sub damage went to 100 percent. Many crew killed or severely injured. Player sub "sunk" disappeared from surface, and death screen arrived.
Believe I was torpedoed by an AI U-Boat. Dark and happened too fast before I could take screenshot.
I've only been killed once by an AI sub, it was a Japanese sub in the pacific. Normally, get more warning as are detected on sound gear or on surface if via sight or SJ radar if enemy is surfaced (on some subs).but I nerfed the subs hydrophones when surfaced.
Waters in ATO are crawling with U-Boats in TMO , so a real danger.
Testing in March 1943, encountered an eastbound allied convoy come under attack by a wolfpack at night.

if you are going to play a mod-set where the enemy shoots torpedos at you, then you need to turn on the Event Viewer because that is the only way that you will know that you have been fired upon.
NONE of the sensors will alert you.

:Kaleun_Thumbs_Up:
lol but I hattttttte the event camera , very gamey to me, distraction as it pops up at inopportune times. I did not use it for testing as its a variable that affects the experience. Using it can up to individual player.
Normally, since the hydrophones work on surface in fleetboats, even if station isn't manned on surface (I move the crewman to the SJ radar if equipped or to another post) but will still provide a "warship bearing/speed/short range etc " contact report and if map contacts enabled, provides the bearing lines so typically there is a warning of submerged submarines about to attack, I've avoided being torpedoed in the past thanks to this warning.
However, I had the hydrophones tweaked to where do not work when boat is surfaced. They did historically work on surface since had both deck and hull mounted hydrophonesthat were useful on surface, but were ineffective if boat was underway at any decent speed. I will either go back to how they were or make a mod that disables them to be activated by player choice. If disabled but have event cam, could work for some though. I wish event cam could be disabled and enabled at will, while on patrol via options menu, could work for me to keep it active while underway etc.
Like almost anything in SH 4, its a balancing act. I love having to worry about enemy submarines, it was a major element missing from stock and although encounters, especially with the AI submerged torpedo firing kind is rather rare, it is possible.
More likely in ATO/ETO to run into them due to the relatively smaller operating areas compared to pacific and how Germans deployed U-Boats(currently just the AI Japanese submarine filling in but player does not see it unless goes to external cam and locates it) .
I'd like to make sure enemy torpedoes had some sort of visible wake and wish could tweak deck watch sensors to visually spot the enemy submarines. Perhaps add a extended periscope that is above water to the model. AI can spot player periscopes, would make sense player lookouts can spot periscopes also. But this is SH 4 lol
Enemy vessels see submerged enemy AI subs as if were surfaced vessels. I've noticed they fire guns at them then when close will drop depth charges, even though no scope above water.

Well, not always practical to report first but I try to at least once as earn renown, alerts friendly forces (especially if operating in a wolfpack in TMO Update, it will bring friendly AI subs to the convoy etc.), and may receive orders to break off, or engage. Then if engage and complete assignment (usually sinking one ship will do) such as targeting any ships or specific ships like tankers, troopships, escorts , chance to earn more renown.
In TMO, mirroring history there are instances where orders from the start say to report and receive receipt before any attack. A famous example was Battle of Philippine Sea, the subs assigned to US operation had standing orders to report contact with enemy fleet units and receive response before they could attack. Including I believe it was Albacore that lost attack position while waiting on a reply from comsubpac, then had to race ahead to regain position. Some skill and luck involved, as found itself in position to torpedo the carrier Taiho, which eventually sunk due to damage stemming from the torpedo hit.

not sure what this little guy ran into.
he and his buddies were making life hazardous for my crew and all of a sudden things got quiet and everyone went away.
we came up to periscope depth to look around...because in RFB the escorts go dead in the water and wait for you to do a sound check, not detect them and then surface. not this time.
anyway, when we came up for a look, we see this odd thing on the horizon. no sound though. we close to a point where we can see the thing and it's an escort, mostly sunk. (segue to Young Frankenstein).
we triple-check that none of his buddies are lying doggo and then we surface and sink him with our 4 incher.
https://i.ibb.co/Dg7wFYCC/SH4-Img-2025-04-16-17-09-32-330.png
here is another mostly sunk escort. again, we did not do anything to him, yet.
we found him more or less like we did the one above, after an attack when things got quiet.
unfortunately, this guy had buddies in the area so we had to use a torpedo to finish him off.

Lol nice. Since RFB does not have AI subs last I checked, unless damaged by air attack? . Most likely damaged by waves, I remember some of the ships in RFB and RFB RSRD had that issue IIRC.

260148 JUN 1943
Approached wounded merchant on surface, attacking from astern. Sank by gunfire from all weaponry. Air search radar detected two aircraft,
on a homeward trajectory. Trusting in the ideal night attack conditions to conceal us, remained on surface to open distance from enemy escort.
Several minutes later observed four-engine flying boat directly overhead, and having seen our wake it appeared to be changing course to attack.
Crash dive ordered, and several explosions heard to stern. Thereafter: pinging. Enemy escort having been able to catch up in this time. Suffered
extremely heavy counterattack that resulted in damage to multiple subsystems, including one cracked battery cell. Minor wounds occurred amongst after torpedo crew and machinist division.

Very nice! Enjoyed the report and screenshots.
How is performance of V2.0 of the update? Any CTD?

Remarkably stable, particularly compared to my SH3 megamods. I've stress tested with some test saves in contact as well and most have worked. I've not yet had an "unforced" CTD.

Yes indeed. I've managed to do two more patrols, which I will post below. I've played around with careertrack.upc and it's really, really easy to transfer a character's stats, etc. to a new campaign. Given it was exceedingly rare to be in command for more than four patrols without a rotation out, I'm going to put old Billy Lee on ice until Jan 1945. Want to play some Dark Waters first.

Very nice! Enjoy your reports.
You seem to have amazing game stability in 2.0. Good to know.
Looks like torpedoes working fine now lol. Getting into 1944, larger convoys, can do more night surface attacks, even get inside convoy. Really is a lot of fun, can really cause havoc.
Yes, I often keep same career, just change name of the CO and his personal tonnage as 5-6 patrols became max. Sometimes, I then transfer the stats to a new construction career . Once reason I hope to include a 1944 new construction for Balao Class and Tench class in the forthcoming update.
Keep up the patrol reports.
I have darkwaters mod on in the download section where I adjusted it so could pull off night surface attacks as u boats did, even inside convoys. Mod is not finished but its fun. Made few other changes also.

Testing out forthcoming TMO Update, specifically numerous ships added.
USS Bowfin (Balao Class)
100 difficulty with external cam and contacts on.
Through cloning, I've created numerous individual tankers and merchants, over 150 thus far. Each has a real life name, with tonnage adjusted as much as possible. Ship models assigned names were done to be as close as possible to how vessels looked in real life. Native ships such as Nagara Maru, Hakusika Maru, and Biyo Maru actually resemble their real life counterparts and images in rec manual appear to be taken from the actual ONI Rec manual.
To test out the work I have thus far. created a Balao Class career, USS Bowfin. December 1943 I was on patrol in Areas B4 and B5 in South China Sea.
At 2301 on 15 December, SJ contact was made on a sizeable northbound convoy. Night was perfect for a night surface attack. No moon, light haze, moderate clouds, calm seas.
Convoy was on base course of 035 at 9.5 knots with nine ships and two escorts. Later discovered to be three escorts. Moved ahead, thrown out of position by a zig, but regained and waited for next one.
Went to General Quarters at 0040 on 16 December and moved in for attack after tracking and the expected zig to NNW, towards BOWFIN. Spotted the previously undetected third escort as it moved at high speed back into port position, blocking initial approach. Broke up and prepared for another.
About 0130, escort went off searching again. BOWFIN, ahead of the convoy at 5 miles, looped back to port side and approached the port column, which had three large tankers, with one merchant leading and one astern, all spaced about 1,000 yards apart.
Assumed the northbound tankers were all full of volatile oil/fuel and one torpedo hit will usually do the job, decided to fire two at the 10,000 ton tanker in no.2 and one each those in no.3 and No.4 position, then one at the leading merchant and trailing merchant.
At 0143;, fired all six bow tubes at a range of 2,355 yds, began turn with stern tubes ready.
Torpedoes 1-5 hit, all three tankers erupted in massive fireballs, explosions, with two outright wrecked and sinking, other exploded and went dead in water. The lead AK was set on fire, went listing and slowed. The last torpedo prematurely exploded about 300 yds from target (still running with magnetic detonators in SUBSOWESPAC command until January44).
The escorts fired off star shells, did usual routine when attacked, but the returning port escort seemed to spot us and closed at high speed. This vessel turned out to be a DD that could do 20 knots.BOWFIN sped away under fire, but none close.
I went to the radar view to look at scope and do some plotting, when I came back to deck view, it was raining! visibility zero. (have to love SH 4) weather lol. For testing purposes, I used ctrl+n, not something would do in campaign, cleared weather.
One escort, was dropping depth charges, suppose AI thought I submerged lol. One saw me and opened fire and while could keep pace, the DE could not overtake BOWFIN's speed. Two "down the throat" MK 14's were fired from stern tubes at 0159 from range of 5,000 yds as it pursued. While neither hit, they did cause the DD to slow, evade, and lose ground in pursuit.
I moved out and took stock of situation. Two tankers had sunk relatively quick, a third was afloat but dead in water, still small fire visible.
The lead AK was trailing behind convoy, listing. I maneuvered to get a shot at the mortally wounded tanker, to finish it off. Fired one MK 14 from 5,000 yards which hit, tanker exploded and eventually went down.
At 0301, while closing in the finish the damaged AK off as it moved at 3.5 knots, it spotted me and opened up with deck guns. One lucky round hit the conning tower near bridge. The XO and one lookout were killed, two lookouts wounded. Still fired two torpedoes, both of which hit, decimating the freighter, which sunk.
I raced away on surface with escorts in pursuit but eventually got away.
Sunk 10,000+ ton tankers :
OTORIYAMA MARU
ARITA MARU
JINEI MARU
Freighter FLORIDA MARU 5,835 tons was sunk.
Just a testing career but obviously after a gun hit to conning tower, can't submerge, head for the barn.
Soon as was hit, my thoughts went to USS Bergall's challenge in December 1944, after being hit by gunfire from a heavy cruiser during a night surface attack.
Since testing, did not attempt to make it home without submerging
