Indeed, quite sad. One gets quite invested in a career/boat after that many patrols and knowing had one more before sailing back to US ( I have that implement in the sim for classes withdrawn before end of war, some dangers possible along the way to keep things interesting) . Of course can't say for sure but am confident that had been in a more modern boat that could submerged faster, go deeper, was more maneuverable under water, probably could have survived, not been hit by the hedgehogs but NAUTILUS was essentially a sitting duck. |

USS BARB SS-220 8 January-14 February 1944 in Area 8
TMO Update V2.0
100 difficulty cams off, map contacts on (for this patrol) With the loss of NAUTILUS due to friendly fire after 14 patrols. Decided wanted to get back into the thick of things and test out some stuff in a 1944 career. So got a GATO and randomly assigned USS BARB SS-220 which I was happy with. BARB is the subject of many "historic contacts" , traffic I added to campaign, based on real ships, which can be located and sunk at or near the actual dates and times of sinking by a particular sub. Since started in Jan 1944, which is before the skipper would who make her famous (Fluckey) took over, I started the career under her previous skippers name and took the objectives assigned. I plan to change the name etc when appropriate time period comes about. BARB was assigned to Area 8 for this patrol, a prime area especially in 1944. This was one of the new patrol objectives I added to campaign. ________________________________________________ WAR PATROL REPORT USS BARB SS-220 WAR PATROL SIX 8 JANUARY-14 February 1944 AREA 8 LCDR J.R. WATERMAN, USN. PROLOGUE Overhaul completed at San Francisco Navy Yard, departed 23 December 1943, arrived Pearl Harbor 1 January 1944.

Course 271 degrees Speed 14 knots Curiously, no aircraft contacts as transited North of Wake and Marcus Islands last few days. Can only surmise recent carrier air strikes have neutralized the increasingly isolated islands as air bases. However, we remain alert for contacts. 0940 Dive 1001 Surfaced 20 January ____________ En route to patrol area. Course 271 degrees Speed 14 knots 0945 Dive 1005 Surfaced 1233 Spotted vessel bearing 333 16202 yards (SJ range) off Sofu Gan. Possible picket or weather vessel. Spotted Sofu Gan. (Ship Contact No.1) 1234 Dive 1236 Depth 150 ft. Speed 6 kts closed target on course 245. 1239 GENERAL QUARTERS-TORPEDO 1348 Periscope depth. Course 198 Speed 2.5 kts Observed a weather tug/picket anchored 5200 yards SE Sofu Gan. Continued approach for torpedo attack. 1357 Periscope depth 64 ft. As scope was raising, three large explosions to port rocked BARB. Spotted BETTY speeding along at 300 ft, climbing. Apparently BARB spotted during approach. Ordered 200 feet. No damage reported. Vessel fired at our periscope as went down. (Aircraft Contact No.1) 1402 While at 200 ft, aircraft depth charged BARB again. Charges exploded above. Ordered 300 ft. Tug heard underway on sound. 1450- Attempted to rise to periscope depth several times for attack on tug. 1700 However, aircraft remained in area preventing this. Tug was underway and maneuvered out of range. 1705 Secured GQ. 2234 Surfaced 21 January ____________ Course 265 degrees Speed 10.5 knots until dawn, increased to 14.5 knots until night fall. 0936 SD contact 18228 yds. Night flyer closing, fast! (Aircraft Contact No.2) 0939 Series of large explosions heard, astern. Given still dark and not likely BARB was sighted, likely that aircraft equipped with radar. 1113 Just after dawn, came to periscope depth. 1130 Surfaced 1539 SD contact 19950 yds closing, fast! Dive (Aircraft Contact No.3) 1542 Depth 150 ft. 1544 Explosions of depth charges/bombs audible through hull, not close. BARB really stirred the hornets nest as believed radar equipped aircraft dispatched to search by day and night for submarine contact off Sofu Gan. This is slowly our transit and it is regrettable we were contacted before entering patrol area. 1600 Turned to course 180, 4 kts submerged until dark. Course change meant to confuse enemy searches. 2146 Periscope Depth. SD mast extended. 2230 Surfaced 22 January _____________ En route assigned area. Course 220 Speed 10 kts 0000 Entered Area CORRIDOR I adjacent to our assigned area. 0300 Increased speed to 15.5 kts. 0500 Turned to Course 260 10 kts 0901 Spotted surfaced submarine bearing 096 at 6500 yds. Appeared to be GATO Class, Likely TRIGGER as transiting her assigned area. Unable to exchange recognition signals, turned to course 180 at flank speed to put her astern. (Ship Contact No.2) 1103 Dive 1133 Surfaced 1135 Course 261 Speed 14 kts. 23 January _____________ TORPEDO ATTACK NO.1 0000 Entered Area 8, began North-South patrol line along suspected shipping route. 0010 Seas picked up. Strong chop but not heavy. Clear skies, low moonlight, Winds at 17.50 kts direction 114 degrees. 0100 SJ contacts bearing 355 28500 yds. Multiple pips, appeared to be convoy.

Convoy appeared to be six merchants in loose formation with one escort forward, one astern. 0136 Forward escort identified as MIKURA Type B Escort Vessel Rear escort appears to be DE type. 0149 Near firing point, convoy made what appeared to be routine zig to SW. 0151 Flank speed, turned to course 105 to pull away from convoy. Rear escort, began high speed sweep along port side of convoy BARB was not spotted, this was believed to be routine escort maneuver as convoy showed no sign of alert. 0153 Rear escort bearing 175 4000 yards. Identified as Otori Class Torpedo Boat/Escort. 0155 Paralleled convoy on course 188 to pull ahead for attack. 0345 Convoy zigged to port course 160. BARB maneuvered to regain position quickly to fire from starboard side of convoy. 0400 Fired Tubes 1,2,3 at Target No.1 :20 0400: Fired tubes 4,5,6 at Target No.2 45 0402 Torpedoes impacted Target No.1 Large fires observed on target. 0403 Torpedoes impacted Target No.2 Large fires observed on target. After torpedo impacts, BARB came under heavy machine gun, deck gun fire, illuminated by strong searchlights aboard Target No.2 (MIIKE MARU) during turn away. Lead MIKURA escort came aboard, fired two star shells above BARB and began closing at high speed. Several rounds of machine gun/auto cannon fire hit BARB's superstructure but caused no serious damage. Several deck gun splashes observed , closed about twenty yards off starboard beam during turn away. 0405 Otori Class Torpedo Boat rear escort observed pouring on the coals speeding BARB's way. The choppy seas made it initially difficult to reach above 19 kts during initial get away but 20 knts was reached. 0412 Otori bearing 180 fired several rounds forward guns Splashes landed well ahead of BARB. One flew low and heard it roar over the periscope shears, splashed into sea about thirty yards off port bow of BAR. However, range continued to open so remained on surface. 0415 Began end around for follow up attack. Observed AK AKAMA MARU 5425 tons sink at 28-32 N 132-38 E. 0416 Depth charge explosions observed/heard 6000 yards astern. Enemy believes BARB submerged. Poor whale/fish taking our punishment. 0421 Observed AK MIIKE MARU 11800 tons sink at 28-32 N 132-38 E. 0426 Tracking large pip believed to be AK making a solo run from area. Bold strategy. BARB closed contact at high speed. 0450 Spotted AK bearing 292 10,170 yards. 0503 Turned about, began to back towards target for stern shot. 0525 Target identified as AK HIYAMA MARU 7145 tons. Course 160 Speed variations of 7-10 knots zigging along course. 0526 Report of enemy pip closing range fast on SJ radar, appears to be escort coming to join the party. 0538 AK HIYAMA MARU changed course 280, possibly to rejoin convoy. Escort closing high speed bearing 130 7000 yards Closing range fast. 0541 HIYAMA MARU suddenly turned hard starboard to course 345, instead of zigging back towards BARB as anticipated HIYAMA MARU increased speed to twenty knots ruining stern shot. Vessel also fired several rounds from her aft deck gun in BARB's direction. BARB turned to pursue, moving to her starboard to avoid oncoming escort now just 5000 yards bearing 335, identified as Otori Class Torpedo Boat. escort (interesting tactics AI pulled here) 0618 Unable to catch HIYAMA MARU, as rejoined other merchant vessels, another AK was on course to cross our stern for perfect setup. Switched targets to AK similar to JOKUJA MARU 7390 tons. 0630 JOKUJA MARU turned North, away from BARB. 0634 As pursuit of JOKUJA MARU was going on. HIYAMA MARU again towards BARB. 0636 Otori spotted bearing 170 5000 yards, closing. 0637 HIYAMA MARU turned away high speed, firing deck guns and machine guns/auto cannons at BARB. Star shell illuminated area. Otori observed heading BARB direction. Ordered flank speed on course 035 0640 Otori was now chasing BARB range 6000 yards bearing 180, closing. 0650 Otori slowed suddenly, then turned back for convoy. BARB secured GQ and ordered forward tubes reloaded. Would end around for follow up attack, before dawn if possible. This would give the convoy a chance to calm down. 0937 Regained SJ contact after end around. Bearing 009 28,350 yards. 0956 Ahead of convoy, waiting for anticipated dawn zig for dawn attack.

While in area for a few days seas did increase with 4-6 foot waves, winds 17-18 knots. Moonlight was on most night almost nonexistent providing ideal conditions for night surface attacks. Some squalls and rough seas were encountered en route to Pearl Harbor from assigned area but nothing unusual. ATTACK DATA Five torpedo attacks were conducted on this patrol, with a total of eighteen torpedoes fired for seven ships sunk.All torpedoes functioned properly to our knowledge. Four of five attacks conducted were on the surface, at night against convoys. Submerged day attack was made on convoy previously attacked during the night. A attempted submerged night time attack was made, but a alert escort detected BARB and prevented attack.

AK HIYAMA MARU* 7145 tons 1944/01/26 0615 27-18N 132-35E Verified by- Observed three torpedoes hit target in stern. Stern blown off of target. Observed target sink visually and disappear from PPI scope. MINES No enemy mines were encountered NAVIGATIONAL AIDES Sofu Gan served as a navigational aid. Otherwise the open sea area provided no aides. THERMAL LAYERS Thermal layers were encountered at 195 feet and 270 ft. SOUND CONDITIONS AND SOUND GEAR Sound conditions were generally favorable in patrol area. Sound gear functioned well, with a marked decline due to damage taken in depth charge attacks. RADAR SJ Newly installed SJ-1 Radar and PPI scope worked well in detecting and tracking convoys. As a policy, SJ sweeps are conducted every quarter hour when on surfaced. Typical detection range was about 25000 yards. SD SD Radar function was adequate, although appears to have difficulty tracking aicraft beyond 10000 yards when at altitudes at altitude of 1000 feet or less. RADIO Radio function was normal throughout patrol. ANTI-SUBMARINE COUNTERMEASURES AND EVASION Countermeasures Overall, enemy ASW measures were standard. Each convoy encountered had two escorts. Lead escort made sweeps to each side of the convoys path forward roughly every fifteen minutes, aft escort did the same, but often conducted sweeps 5000-10000 yards to the rear quarters of the convoys. Rear escort is typically a DE or in our case Otori class torpedo boats, capable of high speeds to conduct this manner of escort and patrol. Enemy aircraft were encountered almost daily in patrol area, with one called in following a series of attacks on 26 January that left four enemy ships sunk, out of six in the convoy (not including two escorts). This aircraft was a night flyer and most likely had radar as it closed in on BARB , forcing a dive. Explosions of bombs were heard above, indicating BARB was detected beyond visual range , at night. Night flyer, possibly equipped with radar were encountered en route to area as well. Following a attempted attack on a weather tug off Sofu Gan, in which a BETTY that was in area spotted BARB at periscope depth during approach and bombed us. For two days and nights aircraft flew in the area along our base course, forcing several dives, and were bombed nearly every time, even at night. Again, the pinpointing of our location beyond visual range, in particular at night, indicates aircraft armed with radar. Open ocean patrols by teams of first line Destroyers were contacted, indicating a strengthened ASW presence, along with aircraft in the vital sea lanes in which BARB was assigned. Enemy depth charge attacks were effective on this patrol. Japanese escorts appear to be equipped with new, more powerful depth charges along with improved sound gear. Team tactics including attacks in rapid succession were used by enemy in both attacks. After some time, one would rejoin convoy while other kept submarine pinned down permitting their charges to open the range for escape. While the ASW vessels were effective, a major flaw is neigh kept their attacks beyond a few hours, departing to rejoin. This is particularly true for the second attack on 28 January, as BARB had serious damage, the early termination of the attack provided much needed relief. Evasion Evasion of enemy aircraft consisted of a dive to 150 feet for 30-90 minutes, followed by a sweep at periscope depth with SD via extended mast. Forces hunting for BARB following encounter off Sofu Gan were evaded by a course change and high speed run further South-East into southern part of area in lieu of maintaining base course. This tactic proved successful as there were no more contacts until reached assigned area. Evasion of depth charges consisted of diving to 300 feet, rigged for silent running, with five to degrees rudder applied to port or starboard at nearly all times, this served to confused enemy as to our exact heading. After first run, BARB descended to 350 ft, then 375 ft. These left typically charges or most exploding above the BARB.However, BARB was forced to 390 feet to get below the enemy's sonar and depth charge patterns. Once at 390 ft, the enemy appeared to have difficulty, overall, tracking BARB. When a enemy would be directly above, a "burst" of speed would by used by ordering 'Ahead Flank' for thirty seconds, reducing to ahead standard and then back to 1/3 after thirty seconds. MAJOR DAMAGE AND DEFECTS Defects No major material defects occurred on this patrol. Damage All damage repaired at sea unless otherwise indicated.

High Pressure Air Lines in all compartments leaked. 23. Light Bulbs and Glass fixtures in all compartments busted. 24. Six inches of water in Aft Torpedo Room-Pump from compartment and bilges. PERSONNEL Crew of the BARB performed well throughout a busy and challenging patrol. Eight men advanced in rating during this patrol Eleven men qualified during this patrol. QM2c John C. Clark was wounded by machine gun fire during night surface attack. Clark was on the bridge as a forward lookout beside the Commanding Officer and Battle Stations OOD when just after torpedo impact, during BARB's turn away, a barrage of machine gun fire hit the forward deck with a few rounds hitting the lower shears and bridge area. Although wounded, Clark remained at his post until relieved and overall had recovered by the time BARB returned from patrol. HEALTHY AND HABITABILITY Crew morale and health on the patrol were excellent. No doubt this was assisted by well prepared meals, generally pleasant weather, and the sinking of seven enemy vessels. MILES STEAMED FUEL-CONSUMED Pearl to Midway 1350 Miles 16550 Gallons Midway to Area 3400 Miles 44865 Gallons In Area 5000 Miles 66,288 gallons Area to Midway 3500 Miles 64944 gallons Midway to Pearl 1350 Miles 16745 gallons DURATION Days Total 44.5 Pearl to Midway 3.5 Midway to Area 14 In Area 9 Area to Midway 14 Midway to Pearl 4 FACTORS IN ENDURANCE Torpedoes 6 Fuel 30,144 Gallons Provisions 34 days Crew Indefinite Factor in Termination of patrol-Damage Both periscopes damaged beyond repair. REMARKS A highly successful patrol, BARB's best to date with seven ships sunk. Area 8 proved to contain vital North/South sea lanes. Three convoys, two Southbound and one Northbound were encountered in the within five days of one another in patrol area. Enemy air and surface patrols, along with escorts protected these convoys well. Enemy frequently uses zigs and course changes to thwart attacks. Finally, the it is regrettable BARB had to depart early for home with six torpedoes left (four forward, two aft) due to irreparable damage to both periscopes, but BARB and her crew remain proud of what were able to accomplish in just nine days on station.

No contacts. Begin day submerged-night surfaced routine since 14.08.1943. Wind and waves changed several times from 12 mps (07.08.1942) to 15mps (16.08.1942) and 11mps (18.08.1942).Visibility excellent to good in general. 19.08.1942 129'40E-28'50N 09:43 - Visual contact with lone japanese large old split freighter, bearing 288 at 9knots.Probably sailling from Okinawa to Japan, apparently armed. Searching a good position for a submerged attack after going to periscope depth. Fired two torpedoes, one hit and other one dude. Sunk for 8198 tons. Returned to transit after visual confirmation of the sinking. 21.08.1942 126'8E-27'27N 04:48 - Operation area reached.

Nearly all were radar equipped. Distress calls for convoys under attack at night brought in radar equipped air support at dawn. APR-1 Radar Warning Receiver installed during refit after last patrol proved a great asset in mitigating effects of these patrols. North of Wake and Marcus Island air patrols equipped with radar harassed BARB daily during transit to and from patrol area. One enemy escort vessel was known to be equipped with radar, which proved useful in providing some idea of BARB's location on surface. A patrol of two DE type vessels encountered on en route from patrol area East of Iwo Jima in area DUNKERS DERP (see contacts) produced radar emissions detected by APR-1. Both vessels appeared to have radar. Both enemy convoys attacked on this patrol had what no appears to be the standard two escorts, one forward, one aft, with each making sweeps. All merchant vessels appear to be armed, some heavily. Depth Charge attack experienced by BARB on this patrol was fairly standard by proved effective in damaging the boat. After sinking two tankers via periscope at night, submerged. Each escort, unaware of BARB's location stopped and listened. BARB was at least 4500 yards from each but their search detected us. Both vessels rushed our location. BARB was at 350 feet, rigged for silent running and depth charge, when first depth charges exploded, well astern of us, apparently the escorts attacked a false contact. However, a few minutes later pinging began and BARB was located. Each escort took turns in rapid succession making depth charge attacks. These escorts are believed to have the improved depth charges encountered on recent patrols. After several tooth shaking patterns, a closer one caused serious damage (see MAJOR DEFECTS AND DAMAGE) to BARB, but all was repaired in due course at sea. However, again a fatal flaw in Japanese ASW escorts, is to give up too soon. After the pattern that damaged, enemy seemed to give up as one was heard rushing away to rejoin convoy. Other went silent, likely to listen for BARB. BARB crept away at 390 feet, with water in control room and forward torpedo room. This flooding plus a damaged trim pump made depth control a challenge at times, requiring some extra speed. A one point BARB descended to 404 feet. Overall, enemy sonar gear, depth charges, and ASW tactics have dramatically improved in recent months. Evasion Evasion for BARB was standard with previous patrols. BARB, if detected by aircraft, upon surfacing would change course and speed to thwart any searches along course steered when detected.APR-1 was found to often detect aircraft, if their radar sets were on, before SD radar detected them. This provided early warning and a dive was made at least once when SD failed to detect what was believed a low flying radar equipped aircraft. Evasion of enemy depth charges was made with utilizing thermal layers, frequent speed bursts, course, and depth changes. Evasion of enemy following night surface attack consisted of turning away slowly during torpedo run and just moments before, ordering flank speed and departing area, at times under fire. MAJOR DAMAGE AND DEFECTS No major material defects. Damage Depth Charge Attack No.1 BARB suffered serious damage during depth charge attack, but all damage was repaired at sea. 1.Flooding in control room and bilges due to numerous busted sea valves. One foot of water in compartment. 2.Flooding in Forward Torpedo Room due to shear dogs on hatch, leaks in damaged torpedo tubes, and busted sea valves. Two foot of water in compartment. 3.

SD SD Radar performance was overall acceptable. Typical detection range was 12000 yards. Enemy Enemy air based surface search radar appears to have a range of at least 30000 yards. Enemy aircraft do not always have the set active, but appear to alternate on and off searching area. Night flying aircraft tend to keep radar on at all times as those encountered in hours of darkness on this patrol previous demonstrated behavior as such. On this patrol APR-1 was able to confirm presence of radar. Enemy escorts equipped with radar did not appear as effective was was on surface and within 5000 yards of enemy escort producing radar emissions and was not detected, until after torpedo impact. Submarines are, as we know difficult targets to detect. Likely a operator on watch noticed BARB's small pip on their scope only after alerted by exploding tanker vessels. RADAR COUNTERMEASURES APR-1 proved a effective tool on this patrol, often providing indication of bearing of a aircraft contact, at times before SD even detected their range. APR-1 detected ship based radar as well and proved vital to the success of this patrol. SOUND CONDITIONS AND GEAR Conditions Sound conditions in area were overall excellent. Hydrophones could track enemy precisely about 5000-7000 yards and distant noises could be heard at great distance. These conditions no doubt assisted enemy in his effect depth charge attack. Sound Gear Sound gear functioned well overall in conjunction with the optimal conditions. Enemy Enemy sound gear appeared improved as were able to hear BARB at 4500+ yards when running at just 95 RPM following Torpedo Attack No.4 and located her with active sonar at 350 ft of depth, rigged for silent running. RADIO Radio function was optimal for most of patrol. Serious damage to radio transmitter during depth charge attack did have lasting effects in spite of our talented radioman's best efforts to repair completely. Function was restored by not satisfactory for remainder of patrol. No enemy radio transmissions or signals were detected on this patrol. THERMAL LAYERS One thermal layer was detected at 209 feet. PERSONNEL Crew performance was once again excellent on this patrol. Eleven men advanced in rating while two officers and eight men earned qualification. HEALTH AND HABITABILITY Health and morale of the crew remained excellent throughout the patrol. Meals were well prepared, certainly helping maintain these conditions along with mostly calm, almost yachting seas and weather. Sinking of four enemy tankers certainly kept morale high as well. Only minor injuries such as bumps, bruises, and scrapes were suffered during depth charge attack. MILES STEAMED-FUEL USED Pearl to Midway 1350 miles 18550 gallons Midway to Area 3350 miles 53865 gallons In Area 7200 miles 99455 gallons Area to Midway 3750 miles 57344 gallons DURATION Days Pearl to Midway 4 Midway to Area 11 In Area 26 Area to Midway 12 Days Submerged 4 Total 57 FACTORS IN ENDURANCE Torpedoes 8 Fuel 26864 gallons Provisions 37 days Reason for termination of patrol: Fuel level. Time on station expired per orders. REMARKS A busy and challenging, but successful patrol, my final in command as will be relieved upon return to port. Depriving the enemy of four large, valuable ,loaded, Northbound tankers and their precious fuel oil cargo was the proverbial "cherry on top" for this patrol. While it is regrettable were not able to expend last eight torpedoes, it is understood the nature of operations as BARB was transiting another's area and accordingly followed orders. BARB is a excellent boat, with a top notch crew that will no doubt have further success. J.R. Waterman (See above for screenshots) Last edited by Bubblehead1980; 03-02-22 at 05:00 PM. |

I've been getting comfortable with SH4 after being a long-time SH3 player, and I've been reading old patrol logs and the background history of the American sub campaign and decided to write a patrol log in the style of the "narrative" reports that were forwarded to command after a patrol was completed.
I left out a few sections which were standard in this style of log, namely miles steamed, days on station and the fire control data for each attack as I forgot to log these initially and didn't want to restart the patrol - I'll remember for next time. There are likely a few minor errors but I hope it's an enjoyable read nonetheless. I'm just playing FOTRS without too many extras at this stage, it's a bit of fun getting creative with the photos and making it look like a typewriter-written report as it would have been in the 1940s. Played at 98% realism, external camera off but left map contacts on while I still learn the ins and outs. I left the images full size for the best resolution, just zoom your browser out to 60-80% if the scrolling takes to long. This career assumes USS Sawfish returned from the boat’s second war patrol earlier than the historical date of June 1943 and places it's return in May of that year, and that the historical skipper of Sawfish at this time, Lt. Cmdr E.T Sands, was transferred - therefore command of Sawfish is taken up by the fictional Lt. Cmdr J.P Salinger by June 1943 for the third war patrol.

DATE: 1 June 1944 Time: 2346-2357 LAT. 47-51N LOG. 151-09E DESCRIPTION: Shimushu Type A Escort vessel, damaged by previous torpedo attack of U.S.S. HERRING (SS-233) sometime on 1 June. Vessel was immobilized, possibly due to loss of prop. Attempted to finish vessel off with torpedo but draft too shallow was vessel was not in ballast. After nightfall, closed to 6000 yards and opened fire with Four Inch Fifty Caliber deck gun. Sixty out of 150 rounds aboard were expended. Sixteen direct hits and eight near misses, left the vessel a flaming wreck, bow to stern. Vessel sunk within one minute of ceasing fire. No survivors were observed. Due to lack of return fire or visible acitiy it is believed all aboard were killed when third hit amidships, set off a massive explosions. Round either struck unarmored fuel reserve or possibly ammo reserve.

Murphy, USN.-Ammo Train GM3c J.H. Petrasanus, USN.-Ammo Train. Casualties: None. (F) NAVIGATIONAL AIDES: Spotted enemy lights and shore batteries on Cape Shiretoko, Karafuto Island. Paramushiru and Taketomi Islands provided for excellent aides to navigation, although no lights were spotted. (F-1) HAZARDS TO NAVIGATION: Several icebergs were spotted throughout the area. 1.47-48N 152-11E 2.53-0N 153-0E 3.51-0N 146-0E 4.51-40N 144-02E (G) MINES: No enemy mines were encountered on this patrol. (H) THERMAL LAYERS: Thermal layers were detected at 90 ft, 91, ft, 100ft, and 200 ft. Majority of area did not feature thermal layers, a concentration of them were found off Karafuto and Parmushiru Islands. (I) ANTI-SUBMARINE COUNTER MEASURES AND EVASION: Enemy ASW in area featured patrols by aircraft across the open ocean. Closer to the islands, namely the harbors warship patrols were encountered. A impressive coordinated response occurred on 17 June in response to the Chidori's reports of being torpedoed by BARB SSW of Paramushiru. Arrival of a DD and DE, along with air support certainly prevented BARB from being able to close in for the coup de grace. Depth charge attack of 19 June was intense, accurate, albeit short lived. Considerable damage was done by two skilled escorts. Impressive, large patterns were laid with variation in depth settings. Each escort took in somewhat rapid succession. One tactic encountered was for one escort to run "up the spine" of BARB, while other crossed our bow, with both laying impressive patterns to trap BARB one large shock wave. This tactic seemed to be used at least twice and BARB suffered damage both times, including flooding. Once again, the Japanese escorts propensity I have read of in numerous reports, to give up the attack early provided welcome relief. Evasion was conducted by rigging for silent running, use of speed bursts at ahead full or flank for 25-30 seconds once escort passes above to drop, frequent course and depth changes. When at 395 feet, a powerful pattern of charges above BARB pushed her to 407 feet. (J) MAJOR DEFECTS AND DAMAGE: No major material defects. Damage BARB suffered serious damage during depth charge attack. All damage was repaired at sea over course of 72 hours unless otherwise noted. Damage: 1. Flooding-Forward torpedo room. Busted valves and lines repaired. 2 ft of water pumped out. 2. Flooding-Control Room. Busted valves and lines repaired. 1 ft water pumped out. 3. WCA Sonar Stack in conning tower jarred lose, rendered inoperable rest of patrol. 4. Forward Batteries 5. Compressor 6. Trim Pump 7. Rudder Transmission 8. No.1 Diesel 9. No.3 Diesel 10. JP Sonar Head-Deck Mounted 11. Radio Transmitter 12. SJ radar antenna. 13. Piping and water lines throughout boat. 14. High Pressure Air Lines in all compartments. 15. Light bulbs-all compartments. 16. Glass fixtures-all compartments. (K) RADAR: SJ SJ performance was overall excellent. Average target detection range was 22,000 yards. SD SD performance was adequate with typical detection ranges at 18000 yards. (L) SOUND CONDITIONS AND SOUND GEAR: Sound conditions in the area were generally poor. Sound gear function was limited to damage in depth charge attack. (M) TIDAL INFORMATION: Tides were typical for the area this time of year. (N) RADIO: Radio function was excellent until damaged in depth charge attack. After repairs, function was hit or miss, so to speak. (O) COORDINATED ATTACK GROUP OPERATIONS: Attempt to coordinate attack proved difficult after initial attack on convoy. One member of group (HERRING) made a attack while BARB was jockeying for position on 31 May, damaging one AK and crippling the convoys lone escort, which BARB later sunk by gunfire. After this attack there was no further communication from HERRING and no communication with GOLET was never established in the assigned area. (Real life note on the wolfpack: HERRING was sunk by shore batteries off Matsuwa in the Kuril Islands on 1 June 1944,vafter sinking the frigate Ishigaki and a merchant of the convoy in question on 31 May. BARB would go on to sink the other two. GOLET disappeared all together without a word, any trace. GOLET's CO, LCDR Clark had told LCDR Fluckey of BARB he would start his patrol off South Eastern Hokkaido. BARB would learn from a rescued Japanese merchant seaman that there were mines laid in that area. BARB attempted to warn GOLET, but never received a reply. GOLET is believed to have struck a mine and sunk. Another source says was sunk by Japanese escorts on June 14 1944 in sea of Okhotsk.) (P) PERSONNEL: Crew performance was excellent on this patrol, as demonstrated by sinking of six enemy merchant vessels, one warship, and severely damaging another warship. As this is BARB's eight patrol, large crew turnover is anticipated during next refit period. Two new officers with no patrol experience, fresh from Submarine School reported aboard at Midway. New "Old Hands" trained them well to takeover on next patrol. One Officer and twelve men qualified on this patrol. Eight men advanced in rating. (Q) HEALTH AND HABITABILITY Health and Habitability were overall excellent on this patrol. Rough Arctic seas and temperatures made for difficulties at times, but crew pulled together and overcame these challenges. Food was well prepared and of high quality. Minor injuries such as scrape, bumps, bruises were suffered as result of depth charge attack. (R) MILES STEAMED-FUEL CONSUMED Midway to Area 2300 miles 37564 gallons In Area 7500 miles 102644 gallons Area to Pearl Harbor 3632 miles 78555 gallons (S) DURATION DAYS Midway to Area 10.5 In area 20 Days Submerged 2 Area to Pearl Harbor 11 Total 41.5 days (T) FACTORS OF ENDURANCE Torpedoes: 0 Fuel: 19244 gallons Provisions 41 days Crew Indefinite Reason for termination of patrol: All torpedoes expended. (U) REMARKS: With six merchant vessels and one warship sunk for estimated 28000 tons, with another warship severely damaged, BARB's EIGHTH patrol, my first in command was a unabashed success. Crew, boat, and torpedo performance were excellent. Commanding Officer does regret was unable to conduct more coordinated attacks with group members. Commanding Officer takes responsibility for the miss of BARB's last four torpedoes due to speed error. For that, a large merchant vessel managed to escape sure destruction. Noted for future patrols on how to avoid such incidents. E.B. Fluckey |

 Patrol area.  Crew morale was listed as "broken" or "shaken" for many after a severe depth charge attack.  Bow of Chidori hit by torpedo. Night surface attack from 3000 yrds. Target slowed in heavy seas, causing torpedo aimed for middle of target to hit the bow. Vessel was badly damage, traveled slow but managed to escape thanks to dawn breaking early in the polar areas, foul weather setting in. Then clearing, arrival of two DE called in to help after dawn, as well as a patrolling aircraft preventing from closing target. (see report) .  Small AK sinking after single torpedo hit (blew up nicely)   DC splashes.  Empty raft after sinking of small merchant. Raft was launched just as vessel capsized. Initially had a lone crew member in it. By time BARB surfaced to close, the raft was empty. Heavy seas so assumed the survivor was washed out.  Lone survivor, soon washed out of raft.  Rendezvous with USS Herring in Sea of Okhotsk 31 May 1944 1000. (Wolfpack operations)  PBY at Midway  Shaken crew (see cursor on morale)   Storms in sea of Okhotsk  Fired a "up the kilts" shot with AOB 180 but unfortunately the drift of the Chidori in heavy seas, torpedo ran down the port side.  Wolfpack message received on convoy. Entire three ship one escort convoy sunk. AI sub (packmate) "Herring" damaged one AK (had a hole in side of it when I located it) and crippled the escort (props and rudders blown off, later located). BARB sunk all three AK and the escort. Escort sunk by gunfire after dark after torpedo run below, showing draft too shallow. |

USS BARB SS-220 Ninth War Patrol screenshots
Few screenshots from 9th patrol. External Cams and contacts were off so not that many shots. Patrol Report to be posted soon. Do not recall if have ever had such a patrol playing without map contacts on. 11 ships with 78622 tons. Luzon Strait in August-September 1944 is certainly target rich environment, but difficult with large well defended convoys.

USS BARB SS-220 NINTH WAR PATROL 4 AUGUST-2 OCTOBER 1944
TMO Update V2.0
100 difficult, external camera and map contacts off. I did my best to keep up with the data on this patrol but the action in the Luzon Straits was busy. Attacks , esp the night surface actions and coordinated attacks required all of my attention, especially operating without map contacts to keep track on things, so my recording of data suffered at times. Having said that, this was my best patrol ever without map contacts on. Six tankers, four merchants, one destroyer. One escort carrier damaged. Fired 48 torpedoes (made a fast run to Saipan for reload after expending torpedoes early in patrol). Wolfpack operations I have added to the upcoming V2.0 of TMO Update were present in this patrol and worked well. AI subs attacked convoys. Some placed in area along convoy routes were scripted attacks. Others set to spawn and patrolled area, responded to contact reports. I have found that they will respond to some degree same way carrier aircraft will respond if a friendly carrier or airbase is nearby when player sends contact report. I am unsure on distance will respond from but guessing at least 20 miles or less. Anyways pretty cool when moving on on a convoy or after attack and see the flash explode from torpedo impact in the night sky. Enemy escorts are occupied making opportunities for attack. US wolfpacks tended to "take turns" , typically three boats in a pack, attack from opposite sides. This tactic can player out pretty well in SH 4TMO now. One coordinated attack I sunk three ships, pack mates sunk three, damaged another, which I later encountered and sunk. Anyways, new level of immersion in the sim, look forward to having it further implemented and refined in next release. U.S.S.

BARB came under heavy deck gun, machine gun fire, with a few close splashesobserved. Star shells and searchlight from a AK illuminated BARB for a timeas opened range into the night at high speed. Lead and returning port escort began to chase BARB but never had a exact fix on her location. 0058 Both lead and port flank escorts observed heading for BARB at high speed. Port escort, tentatively identified as a Type A Etorofu Escort, opened from about 3000 yards, but ceased fire after firing four rounds. 1008 Large AO sunk at 19-42N 119-00E 1011 Observed flash in distance and visible smoke fire. Appears another submarine attacked convoy from starboard side as all three of BARB's torpedoes fire hit her target and MK 18 would have reached end of run by this time. 1012 Escorts gave up search for BARB, rushed toward other side of convoy. As convoy was now technically out of BARB's area and entered Area A2 in command area of COMSUBSOWESPAC, BARB turned North to disengage. (This was not a planned/scripted attack in the campaign files. However, this area has several AI subs roving during this time period, as these waters had so many US subs the folk lore among Japanese sailors was "You can walk from Singapore to Tokyo on the periscopes of American submarines" Convoy stumbled across where a AI was on patrol and/or the contact report sent earlier, drew a nearby sub, which does happen if AI subs are close enough) 1035 Secured GQ. 1040 Unknown AK torpedoed by unknown submarine appeared to sink at 19-42N 119-00E.

Convoy sailing in four columns spaced about 2000 yards apart, with about 1000-1200 yards spacing between ships. Total pips counted in the "main body" were 14-16. A ring of six or more pips on scope, presumed to be escorts surrounded the merchants. Initially attempted to shadow convoy until night fall for coordinated night surface attack. However, after forced to dive to avoid SD contact (convoys air cover), convoy zigged towards BARB while submerged deep. At periscope depth convoy was just six miles to port and closing. With enemy coming to BARB, decided to attack. Submerged, BARB worked inside convoy from the front starboard, avoided a Matsu Class DE (radar equipped) lead escort, and crossed the outer starboard column. Lead AK in first center column was a smaller vessel, ignored it as spotted AO SANRAKU MARU 3000 tons astern. Being northbound, tanker was suspected to be carrying oil to Japan, indicated as well by riding lower in water. Approached tanker and fired three MK 14-3A torpedoes at a range of 1511 yards.

However, a spread was fired to account for being detected given daylight and clear conditions or attack or torpedo malfunction. Convoy attacked was quite large and well protected by Japanese standards. Reports ofa increase in enemy convoy size, composition, and protection, including multiple escorts and air cover have become normal as of late. Formation spacing made attack more than one target at a time difficult. Enemy escorts and air cover were first team and proved a challenge. One exception, is a apparent failure by enemy air cover to report having bombed BARB or miscommunication, that led to convoy zigging toward BARB, setting up convoy for submerged attack. __________________________________________________ _________________________________________________ U.S.S.

With engines on overload, BARB was able to outpace two subchser type escorts, but naturally, the DD, guided by his radar, closed at a high rate of speed estimated 30+ knots and was overtaking BARB. Decided to utilize the wakeless electric fish loaded in stern tubes for "down the throat" shot.. Almost as if the DD's Captain sensed this, she began to zig back and forth along her track, at 25 knots estimated, as she was still closing the range. A quick estimation of the timing garnered a solution with a chance to work. Fired two MK 18-2 torpedoes from tubes 7,8, at a range of 3100 yards. Fired tube MK 18-2 from tube 10 at 2900 yards.

Quite surprised after the first hit, DD continued its pursuit of BARB. There was a 120 second interval before the fatal torpedo was fired from the first two. DD was making his zigg to port and sailed right into the well timed fish. MK 18 fish, with their lack of wake are preferred for placement in stern tubes for just this sort of situation. __________________________________________________ __________________________________________________ _____ U.S.S.

Vessel erupted into the massive fireball characteristic of fully loaded tanker after first hit. As vessel was part ofa southbound convoy, likely carrying refined gasoline to enemy forces abroad.Came under heavy deck gun and machine gun fire vessels in outer column. BARB was briefly illuminated by spotlight and star shell. Gunfire was not accurate but a few close splashes. BARB was illuminated for a time by star shells and searchlights. Escorts (lead and port) chased BARB and fired upon, but never located exact position. __________________________________________________ __________________________________________________ _ U.S.S.

All three torpedoes hit, igniting a massive, devastating, explosion and fireball expected from a fully loaded tanker. Second torpedo hit seemed to set things off. Third torpedo hit aft under stack, set off another massive explosion, likely blowing out her boilers/engines. Tanker took a down angle by stern with fires ranging. With BARB just 1500 yards away and on the surface, the sounds and sights really set in for BARB, especially those topside. BARB came under heavy, but inaccurate gunfire from nearby vessels. __________________________________________________ ___________________________________ U.S.S. BARB (SS220) TORPEDO ATTACK NO.15.

Out of torpedoes, with star shells illuminating area, under machine gun fire from the AK, BARB had to turn away and depart area. Observed the AK was damaged, slowed and the went dead in the water. Obviously propulsion/steering damaged by the torpedo hit to the stern. Rest of convoy moved on, but one AK remained in area. BARB hung out in area to wait out the escort, so could finish off the AK with deck gun if possible. (See Gun Action No.2) Gun Actions USS BARB (SS220) GUN ACTION N0.1. WAR PATROL NO.9.

All torpedoes expended, BARB shadowed convoy, send contact reports. Convoy came under attack by one, possibly two other submarines vectored in by contact report. In order to provide a distraction to escorts, induce further chaors, and hope to damage enemy, BARB opened fire from 5000 yards off port side on the escort carrier. SHIP DAMAGED: TAIYO Class CVE 17830 tons 20-50N 118-4E 0904 1944/09/17 DETERMINED BY: Observed a direct hit on flight deck aft of carrier. A small explosion occurred followed by a fire which burned for some time. A large objective believed to be aircraft parked on stern blowed overboard into the sea.

(G) MINES: No enemy mines were encountered on this patrol. (H) ANTI-SUBMARINE COUNTERMEASURES AND EVASION Enemy ASW activity in the Luzon Straits area was intense and primarily consisted of day and night radar equipped air patrols. Many flew low making timely detected by SD radar difficult. As a result, several were detected at just 5-6 miles and BARB was subseuqently bombed several times. A new tactic by enemy air patrols appears to be to fly low at high speeds, which makes early detection via SD radar difficult as it reduces detection range. Enemy appears to keep radar off at times and turn on as needed based on APR-1 readings. Surface patrols consisting of DD/DE were encountered and avoided. One responded at a attack on a convoy and was inbound to assist a crippled vessel damaged by torpedo and finished off later with gunfire. A midget submarine was encountered in the Balingtang Channel off Babuyan Island. Given their limited range and thus need to operate from nearby base, highly likely this boat was patrolling the channel for our submarines. BARB was submerged when spotted the sub and out of torpedoes, so had to evade. Enemy convoys transiting area often had air cover and one convoy encountered had a escort carrier in the convoy. All enemy convoys encountered had at least four escorts, sometimes as many as seven or eight. These vessels were typically purpose built escort vessels "Kaiboikan", some eve DD and DE type escorts. Typically, at least one escort in convoy was radar equipped. A radar equipped DD (Fubuki Class) detected BARB on surface at about 6000 yards and pursued. BARB sunk this DD with a "down the throat" shot from stern tubes. (Torpedo Attack No. 10). Depth charge attacks were intense and accurate on this patrol. Enemy has expanded his ASW capabilities with improved, powerful depth charges and sound/sonar equipment. BARB, out of torpedoes, but working inside convoy to come up to depth and broadcast radio report, was detected as she ascended from 350 ft and passed 150 feet by a escort some estimated 4000 yards away. With multiple escorts in convoys, usually at least two remain in area to attack, sometimes more, employing apparent team tactics. Often conducted attacks in rapid succession. Evasion of enemy ASW consisted of diving to avoid aircraft. Often times it was found the APR-1 Radar Warning Receiver detected a aircraft's radar emissions prior to SD contact, Several dives were initiated due to APR-1 signals prior to contact. Submerged evasion of attack consisted of silent running, consistent course, and depth changes, combined with "sprred bursts" of 30-45 seconds during and imemdiately after depth chrge explosions. BARB's ideal evasion depth has been found to be 390-395 ft. One strong pattern did push BARB from 385 ft to 412 ft. BARB is a well built boat and the 112 ft past test depth seemed to do her no harm. (I) MAJOR DEFECTS AND DAMAGE: No major material defects occurred on this patrol. *Most damage was repaired at sea. However, serious damage to Hydraulic pumps, **Bow and Stern dive plane transmissions rendered BARB somewhat sluggish for remainder of the patrol, especially when submerged, in spite of repairs. All damage listed was repaired at sea unless otherwise noted. 1. Hydraulic Pumps-Seriously damaged. 2. Bow Dive Plane Transmission** 3. Stern Dive Plane Transmission** 4. Flooding-Aft Engines Room-Sea valves busted. 2 ft water incompartment and flooded bilges. 5. Flooding Aft Torpedo Room-Leaks from aft tubes. 1 ft water in compartment. 6. Trim Pump 7. Forward Batteries 8. Compressor 9. Torpedo Tube No.10 10.Torpedo Tube No.7 11.JP sound gear 12.Various pipes- Leaks in all compartments. Serious leak in conning tower. 13.High Pressure Air lines-Leaks in compartments. 14.Light bulbs-All compartments 15. Glass fixtures-All compartments. (J) RADIO: Radio function, especially key on this patrol due to group operations was excellent. Messages sent and received with little to no trouble. (K) SOUND CONDITIONS AND SOUND GEAR: Sound conditions were overall excellent in the patrol area. Sound gear functioned well until damaged by depth charge attack. JP listening gear was not at optimal performance for remainder of patrol. (L) RADAR: SJ SJ-1 radar performance was excellent on this patrol. Typical detection range was 24,000 yards. PPI scope once again proved itself a major tactical advantage for BARB. SD SJ radar performance was somewhat inadequate on this patrol. A apparently new enemy tactic appears to be to fly low at high speed, which made early detection difficult at times. Typical detection range was 11000 yards or less. APR-1 often detected radar emissions from aircraft prior to SD contact, providing some early warning. Enemy Radar Nearly all enemy aircraft in area were found to be equipped with radar. Based on encounters it is believed enemy air mounted surface search radar has a range of of about 15000-20000 yards. Daytime aircraft tend to make sweeps with radar intermittently and focus on a target at close range, perhaps to counter our radar warning equipment. Night fliers tend to keep their radars active at all times. Enemy ship based surface search radar was encountered on at least once vessel in each convoy. Against a surface submarine the enemy raar appears at times ineffective. However, BARB was detected at least one from 6000 yards by a destroyer, prior to attack. (M) THERMAL LAYERS: Two thermal layers were recorded on this patrol. 1. DATE 1944/08/31 TIME 0044 DEPTH-216 ft LAT.21-4N LOG.119-44E 2. DATE 1944/09/15 TIME 1450 DEPTH 130 ft LAT. 20-47N LOG. 120-05E (N) RADAR COUNTERMEASURES: No known radar countermeasures wer encountered. While it is not believed typical enemy vessels or aircraft encountered can detect radar emissions, BARB exercises caution by keeping SJ radar off for majority of time, with sweeps every 15 minutes during standard patrol. Sweeps may be somewhat longer when in contact with/tracking a enemy. (O) GROUP OPERATIONS: For this patrol, BARB was assigned to Task Group 17.5 (TG 17.5), a coordinated attack group, or "Wolfpack", with QUEENFISH and TUNNY under the command of CAPT E.R. Swinburne, USN., embarked aboard BARB. Group was nicknamed "ED's ERADICATORS" after our Commodore. Assigned to the Luzon Straits area, pack operations proved effective and costly for the Japanese. Another Wolfpack, under CDR T.B. Oakley, CO of GROWLER, "BEN's BUSTERS" operated in area the West . The BUSTERS consisted of GROWLER, PAMPANITO, and SEA LION. Further underway training was conducted en route to Midway from Pearl Harbor. Upon departure from Pearl Harbor, group formed a scouting line fifteen miles apart with BARB in the center, TUNNY to port and QUEENFISH to starboard. This line was maintained the entire journey from Midway until reached the Bashi Channel to enter assigned area in Luzon Straits. Each boat proceeded independently into assigned area throughout the strait on surface at night. BARB, QUEENFISH, and SEA LION each patrolled their own designated sector of the assigned area. After several days of empty seas, contact was made with a convoy on August 30 and coordinated attacks throughout night and early morning of 31 August savaged the convoy. BARB sunk three of her ships, two, possibly three were sunk by her packmates. Follow up attacks on September 1 left more vessels sunk. Contact was lost with TUNNY after 1 September, as she had apparently been seriously damaged by aircraft bombs and departed area. BARB expended last of her initial torpedo load and proceeded to SAIPAN to reload torpedoes. Activity in the straits was somewhat absent during BARB's trip but upon return shifted into overdrive. While en route to join the BUSTER's for a coordinated attack, BARB encountered a large convoy and attacked, sinking a tanker. Night of 11/12 September, convoy was attacked by BARB, GROWLER, SEA LION, QUEENFISH, and later ,PAMAPNITO, at least five ships were sunk and others damaged. Unknown to all at the time, Allied POW's, mainly British and Australians held captive since Fall of Singapore in early 1942, were aboard as were being transported to Japan. PAMPANITO first discovered these poor souls and reported in. BARB and QUEENFISH were directed to the area to assist in the search, locating five men in the water, four Australians and two Brits. On the 16th, BARB was out of torpedoes, but encountered a convoy with tankers and a escort carrier Shadowing the convoy, her contact report brought in QUEENFISH, which attacked and sunk a tanker, confirmed. Although out of torpedoes, BARB opened fire on carrier from 5000 yards with 4 inch deck gun. This was meant as more of a diversionary tactic, and it worked. After scoring a hit, which blew aircraft off her deck and set her afire,enemy escorts backed off depth charging the QUEENFISH and raced towards BARB, with promptly withdrew. Overall, coordinated group attacks worked well, especially in this area, where large, well defended convoys are the normal. Chaos caused among a enemy convoy by coordinated attack served the group well in evasion. Group sunk a total of seventeen ships. BARB (11), QUEENFISH (4), TUNNY (2). BARB also damaged a CVE by gunfire. QUEENFISH damaged at least two other ships, TUNNY damaged at least one. (P) PERSONNEL: Crew performance was excellent throughout this patrol. This is best attested to by eleven ships sunk in total, with one carrier damaged. One Officer and twelve men qualified on this patrol and four advanced in rating. (Q) HEALTH AND HABITABILITY Health of the crew and habitability of the boat were overall excellent on the patrol. Extra crew (two officers, plus survivors rescued from water later in patrol) were accommodated with little to no issue. Food was overall excellent and always well prepared, even with somewhat extended duration of the patrol. A "pit stop" at Saipan half way through patrol of course assisted with these matters. (R) MILES STEAMED-FUEL CONSUMED (These are estimates, I lost my mileage/calculations somehow, did not save. Not doing them again lol) Pearl to Midway Miles 1350 Gallons 16550 Midway to Area Miles 3780 Gallons 58560 In Area (Prior to refit) Miles 3500 Gallons 71,500 Area to Saipan (Refit) Miles 1750 Gallons 26500 In Area (Post Refit) Miles 8500 Gallons 145800 Area to Saipan Miles 1850 27950 Saipan to Majuro Miles 2400 Gallons 39,556 (S) DURATION DAYS Pearl to Midway 5 Midway to Area 15 In Area 6 Area to Saipan 4.5 Saipan to Area 4 In Area 13 Area to Saipan 4 Saipan to Majuro 6 Days Submerged 3 (T) FACTORS IN ENDURANCE: Torpedoes: 0 Fuel: 23566 gallons Provisions: 34 days Crew: Indefinite Reason for termination of patrol: All torpedoes expended, survivors aboard in need of medical care. (U) REMARKS Busy, long, challenging, but ultimately rewarding war patrol. BARB sunk six tankers, four merchants, one destroyer, and damaged a escort carrier by gunfire in fifteen torpedo and three gun attcks. Total estimated tonnage sunk is 78677 tons. Sheer volume of enemy traffic throughout area provided for a pace of operations not typical of other patrol areas. Luzon Strait as one would assume, if a vital choke point for enemy shipping. Multiple large, well defended convoys, pass through a area well patrolled by enemy aircraft and surface vessels. Aside from of sinking enemy vessels, BARB rescued six POW's from the sea, inadvertently put there torpedoes of our subs, when ships they were aboard, bound for Japan, were sunk on 11/12/ September. This was BARB's Ninth War Patrol, and my second in command. E.B. Fluckey |

TMO "Evil Aircraft" sunk the BARB.
USS BARB SS-220, was lost on 18 November 1944 at 32-09N 127-36E in Area 9, in the East China Sea, just south of Tsushima Strait.
BARB, chased a convoy all night, after multiple attempts, was unable to attack on surface due to vigilant, radar equipped escorts. Tried for a dawn approach submerged , but was spotted by a PETE floatplane which spotted BARB at periscope depth, alerting escorts. Escorts located BARB in the waters with 315 max depth waters and after a depth charging lasting from dawn until noon 18 November, BARB had escaped and was cruising at 300 feet, just off the bottom of the sea, when began rise to periscope depth at 1900 for a visual check , after hours of no contact with enemy. As BARB passed 125 feet on way to periscope depth, heard a brief noise(presumed to be the low flying aircraft), and then two depth charge explosions which severely shook the boat. Followed four seconds later by even more intense explosions. Lights went out for five seconds, flooding reported in stern, damage reports rolled in, along with calls for medic. I had external cam on this patrol, so went outside after first explosion. One aerial depth charge had landed to port, could see the explosion bubble dissipating, while the second depth charge landed to starboard and exploded just as I got to external view. So two aerial depth charges bracketed BARB's stern about around the point where stern torpedo room bulkhead to maneuvering room would be on a GATO sub, very close. Perhaps 20 feet, within kill range for depth charges typically. Then I saw the aerial bombs dropped, one of which scored a direct hit on the stern. Yep, the lucky, bomb contacted the stern around the stern torpedo room loading hatch. (I tried to screenshot, hit the keys but apparently not fast enough as this happened quite fast) BARB's stern had taken two close depth charges, and a few seconds later, a DIRECT bomb hit seconds later from a EMILY flying boat, which likely detected BARB with MAD (TMO planes have a sensor simulating MAD in late war). and was lined up for attack as we , not aware of the plane, began rising to periscope depth. Stern was destroyed, wrecked. Large hole blow in it, with port prop shaft and stern torpedo bulkhead destroyed, nearly all equipment smashed and sadly, all but one crewman killed in the stern torpedo room, with one severely injured (health was 20/100. Flooding also in engine rooms , bulkhead 90 percent damaged with all suffering severe injuries in compartment. Hull damage was at 80 percent. Boat lingered a few moments, stern torpedo and engine rooms rapidly flooded, BARB took a down angle by stern and paused at 88 feet, stopping her ascent, began rapidly going down in spite of ahead flank speed.. Blew ballast tanks to get to surface to save the crew but did not rise in time as flooded out compartments stern dragged her down . Boat, in 300 ft waters with angle caught its self and bow was about to break the surface while what was left aft touched bottom. Just then, EMILY made another attack at BARB was at 94 ft, dropping a depth charge above, but not terribly close, yet close enough to shake the boat. Bow slid beneath surface, stern crashed into bottom. Hull collapsed, went to 100 percent. All was lost. Oddly enough, the boats external model then just disappeared lol but could stay inside, no controls worked, but game did not end. I had to exit. Side effects of altering the damage model is sometimes SH 4 does not play out the "fade to black" sequence . Can also have to do with the bottom. I've been depth charged, pounded into the sea floor before, where sub disappears lol and external model is gone and im dead, but dont get the death fade to black sequence. Definitely a lucky hit for the plane. This was first time I've been sunk or even severely damaged by aircraft in years lol. Disappointing. really had a great campaign going with the BARB and this patrol was a exciting and successful one already with just eight torpedoes left aft (All but three fired forward, all bow tubes disabled in November 15 depth charge, could not repair at sea) Survived these depth charge attacks, being fired at, and chased on surfaced, but taken out by a flying boat. Ahhh. Reminded me of how TMO aircraft earned their reputation for being "evil".  BARB, during her 10th patrol, which she was on at time of loss, sunk the following vessels: AO CHIYODA MARU 5004 tons 8 November AK JOKUJA MARU 7200 tons 8 November Aikoku Maru Class Auxiliary Cruiser 14500 tons 10 November CVE Akitsu Escort Carrier 11800 tons. 15 November Ah, well to start a new campaign. Screen shots:  Akitsu Class Escort Carrier (Akitsu Maru Aircraft Transport operated by Japanese Army)  AKITSU exploding a few minutes after taking 3 MK 18 torpedo hits.  Akitsu listing to port  First view of Akitsu through observation periscope.  Akitsu  Akitsu burning  Akitsu on fire listing. Took about 15 minutes to sink.  Akitsu listing  First MK 18 torpedo impact  Second MK 18 torpedo impact  DC pattern on 15 November following sinkng of Akitsu. From a Type C escort. Believe this was pattern which damage forward torpedo compartment. Caused some flooding , disabled forward dive planes transmission and tubes 1-6. All six bow tubes could not be repaired at sea.  EMILY which sunk the BARB, flying away after initial drop that scored the fatal hits.  Last DC explosion, following follow up drop by the EMILY H8k flying boat. Unfortunately, the halo effect did not show up on this one as it does usually.  Sunrise 18 November 1944, escort hunting for BARB as she approached convoy,
