In my opinion, the dangerous part of the Mark 14 and the Mark 18 was the failure to have vane limiters for the rudders. Cost saving... Spend all that money on a weapon, and especially the 18, the vane could lock full-over, especially if shooting with a higher angle.

Quite infuriating to think how many lost their lives and the boats lost due to the torpedo issues...especially circle runs. We know of two for sure (Tang, Tullibee) and appears Grunion was lost to a circle run as well. Likely some of those unexplained losses were due to circle runs. Then all the close calls. One that always sticks out to me is from the book "The Luck of the Draw", USS Pollack in 1943. Night surface attack on a convoy...this was before magnetic features were disabled. They fired MK 14's are convoy, one (unobserved) circled back and exploded directly below Pollack. Knocked her systems offline, she went dead in water. Only thing saved her is torpedo ran deeper than set, so they do not catch the full power of the explosion. However, this explosion alerted a nearby escort, which promptly spotted Pollack and began closing at high speed, while Pollack's engine and maneuvering rooms worked to get things back on line, which they did, barely in time. Two failures, but one actually saved the one (running deep). |

I almost forgot that there was also mention of the material used on the Mark 18 for vane pivots... or maybe the friction bearing? I cannot remember... but due to the environment on a submarine, submerged in the saltwater and humidity of the ocean over time, the pivot points had a tendency to corrode, contributing to the stuck condition of the vanes, in that the gyro could not "pull" the vane back once it went over, so whereas the Mark 14 would run erratically, the Mark 18 just turned into a circle runner...

Hi Bubblehead1980, This is interesting to me! I'm currently trying out KSDIIAce, October 1942, leaving Bordeaux through the Bay of Biscay and now postioned west of the Canary Islands, heading toward South America: Not a single enemy A/C in 1 week! I'm beginning to wonder, if there is something wrong with the airstrike.cfg settings. Don't get me wrong: It's not like that I want to be killed by A/C, but zero airplanes seems a bit "unrealistic" to me. Would you (or anyone else) have any ideas, what could be the issue? Here are my current "Data/Cfg/AirStrike.cfg" settings (no changes made): [AirStrikeSettings] ; AirStrike Creation Parameters ; Airstrike Session: ; 1. Compute airbases in range according to their aircraft maximum ranges ; 2. Compute air coverage factors on allies/axis/neutral on the target zone ; 3. Compute airstrike probability from each base ; 3.1 check number of aircraft that can strike at that range and conditions, and compute a coverage factor based on the range of each aircraft type ; and detection area around submarine ( 10 km radius ) ; 3.2 multiply coverage factor for the target area with : ; - current airstrike probability againt that side ; - nigft factor ( if necessary ) ; - airbase competence ; - close to airbase factor ; 3.3 check probability for airstrike ; 3.4 add more aircraft probabilistically for a large target Maximum Aircraft Range=1500 ;[>0] in kilometers Poor Airbase Modifier=0.7 ;[>0] Modifier for poor airbase (carrier) rating Novice Airbase Modifier=1.3 ;[>0] Modifier for novice airbase (carrier) rating Competent Airbase Modifier=1.7 ;[>0] Modifier for competent airbase (carrier) rating Veteran Airbase Modifier=2.2 ;[>0] Modifier for veteran airbase (carrier) rating Elite Airbase Modifier=2.5 ;[>0] Modifier for elite airbase (carrier) rating Night Modifier=0.15 ;[>0] Modifier on strike probability at night Default Air Strike Probability=30 ;[>0] Default probability to send an airstrike from a airbase (carrier) Enemy Air Strike Probability Increase on Radio Messages Sent=40 ;[>0] Increase over the default probability on a radio message sent Friendly Air Strike Probability Increase on Contact Report Sent=70 ;[>0] Increase over the default probability on a contact message sent Enemy Air Strike Probability Increase on Player Detection=50 ;[>0] Increase over the default probability on player detection Atenuation Factor=10 ;[>0] decrease from an increased probability to default one on each air session Logic Steps Between Air Sessions=40 ;[>0] steps between air fighting sessions, 10*Logic Interval(90sec)

Here are a couple of examples to consider Kapitän:
First, the Stock game: ... and from FotRSUWe set all airplanes and airbases to "Elite" so the planes fly better. We also shortened the range in FotRSU since we were getting small planes way beyond their actual capabilities, and increased the Logic Steps substantially. The math for that is "42 steps times the 90, times 10) which equals 378000 seconds, which comes to about every 10.5 hours, which seems to make sense in most areas, as far as traffic patterns are concerned. A few things to remember about the figures is that ALL the AirBases near where you are respond to your submarine's presence. So if you are detected, you might four or five or more airbases sending everything they have after your submarine. Very unrealistic. That Logic Steps is something to really experiment with. The AirBase Modifiers are multiplication things that increase (>1) or decrease an AirBases (<1) capability to respond, and how strong that response is. So an Elite AirBase in the mod not only sends a strong airplane, but it sends 2.5 times that response, and that figure divides the Logic Steps, since the AirBase is capable of responding faster, so now in FotRSU, that 2.5 modifier would make our 10.5 hour session into less than 2 and a quarter hours - from each base of that CrewRating level that you are within range of, so you might be blanketed in airplanes if detected in the Bay of Biscay. Most of the other "modifiers" for radio and night, etc., are "percentages", which modify the Logic Steps also, such that if you sent a radio message to BdU, you increase the odds of an air attack in your immediate area by 40%. It can be a real bother to attempt to balance those settings, and as mentioned, the number of available airbases (land or carrier based) comes into play. One really strange quirk in the game's airplanes, no matter the mod or how high the airplane's CrewRating (Elite flies the best), but if your submarine is detected and an airbase responds and sends airplanes your way, but there is an intervening land mass higher than 500 meters (the default height planes spawn at), the airplanes will crash into said land mass... they cannot fly over or around the land mass. They will beeline on the shortest route to your submarine... ![]()

Wow, seems to be a real science and YOU are the professor! Many thanks for your answers! Quick clarification questions: - When you say 'Stock Game', you mean Sh4 Pacific Wolves, yes? - What does 'FotRSU' stand for? - When you say, 'We set all airplanes and airbases to "Elite', who is meant with 'We'? - When looking at 'my' (KSDII-Ace) airstrike.cfg settings, is it in your estimation 'normal' that I would not encounter any A/C? - Which settings should I use to increase the probabilty of A/C attacks? Thanks again!

I am still looking into the Dark Waters airplane situation. I used my airstrike.cfg from TMO Update V.20 mod I made. I'm not at home or would just post the file here. Thus far I have had more planes but still too few. I am waiting to see how things perform as war goes on. There may be issues with airbase placement (Propbeanie mentioned the land mass issue) as well as the airbase rosters. If numbers are too few to cover their patrol radius defined in the airstrike.cfg, will not see many, if any planes. I have not had a chance but also possible they are set to competent or worse and not veteran or elite, that can play into things. The factors below are rather low also. Default Air Strike Probability=30>>>I increased it to 90 I believe Enemy Air Strike Probability Increase on Player Detection=50>>>changed this to 95 I believe. |

I loaded up Dark Waters on my laptop while out of town. Ugh I miss the desktop use exclusively for SH 4 at home lol.
Anyways, left port on Feb 3 1941 in a Type IXB (prefer Type VII but figured would give the big boy a try). I am assigned to U-123 and as such decided to change captain to her real Captain's name, Reinhard Hardegen. Patrol took me down to Africa, off Cape Verde Islands. I searched and searched for convoys but nothing. Used the maps that came with Dark Wates, nothing. All found so far was three merchants, armed, making fast runs solo. Two were not even in my assigned grid, the third was. Now April 1941 and turning for home after 60+ days at sea. Wondering if its just me if anyone else found convoys in this time period? Seems the Africa convoys from Freetown would be booming by this point |

To answer your "quick clarification questions" : - When you say 'Stock Game', you mean Sh4 Pacific Wolves, yes?

Fall of the Rising Sun - Ultimate - When you say, 'We set all airplanes and airbases to "Elite', who is meant with 'We'? The "we" in this instance, would be propbeanie, s7rikeback & others who work to update & upgrade FotRS-U, which at last check was in v1.7x (x being whatever # in use after the 7 here... ![]() ![]() As for... the last 2 points, I shall defer to another to answer on them... who is... better equipped to do so... ![]() ![]() Hope this helps... clarify things, for you there...

Anyway, I would probably start with turning down the AirBase Modifiers a bit, and then increase what Bubblehead1980 mentions, but I don't think I would go very much higher than what the mod already has. You are liable to be blanketed with airplanes once you are sighted. I would probably then decrease the Logic Steps down to maybe 35 for an experiment, and see if that does the trick. Early in the war, there are not enough airplanes for the Allies, and not many that could do the long haul of an ocean search. Once Lend/Lease kicks in, then the airplane traffic should increase, and once you get to mid to late 1942, you should find it rather difficult to get across the Bay of Biscay without being spotted at least once, and having to deal with "hiding" for a while by direction and speed changes submerged, causing you to take at least twice as long to get out of the air coverage there. When the H/K CVE groups start to roam about the place, and radar improves, you would expect to be Leigh-lighted a time or two at night, and you never having seen any indication of inbound radar beams... In SH3, the only time I made it past Spring of 1943 was when I started the game then... ![]() ![]()

Are there any alternate interiors for Type IXA/B? The interior used i for Type IXC on, with both scopes in conning tower. From what understand, A/B had attack scope in conning tower and observation scope in control room.

Love this mod, but haven not been killed this much since first played TMO way back lol and that was always by depth charge. Now, none were by depth charge, once was pure luck on enemy's part.
1st career Type VIIB Sep 1939-April 1940 Court Martialed for sinking too many neutral vessels (all in convoys with enemy). I was unaware of this, changed it in DW, no longer happens. So I started another career in a Type VIIB in summer 1940...freak long range lucky shot from corvette while on surface at night after sinking multiple sips in convoy....hit in stern torpedo...of course with the great damage model...hole in pressure hull means flooding. I was then rammed on surface. Started another career in Type VIIC In Fall 1940. Excellent patrol, really cleaned up. 90 KM from Lorient, killed by aircraft , direct bomb hit. My fault for underestimating planes of the mod and time period, staying up to gun it out. Although, he was on fire and did crash just after we went under to the bottom. Spring 1941..Type IXB U-123....ran into convoy in North Atlantic...they zigged throwing their columns all out of whack, I got inside on surface... sunk four ships....three merchants and one 8500 ton tanker...One torpedo each, damaged (unsure if sunk) two more with stern torpedoes...just after last torpedo impact....large freighter came out of nowhere it seems and rammed my boat.Flooding in three aft compartments. Then to top if off, a armed merchant scored a gun hit on my conning tower. Boat sunk quickly. So, now restarted July 1941 in Type IX U-43. Back in North Atlantic Convoy lanes. Love this damage mod, may tweak it a little. Would love to get something like this into current TMO model. |

Hmmm just had a aircraft spotted at 11 KM (Clear Sunny day) in Grid AL 58.
That is 1033 KM south of Iceland and 1391 KM West of Ireland. I easily submerged and do not believe he spotted me, so obviously not running ASV yet. However, should have contacts this far out in July 1941? This is the air gap no? |

I forget how we arrived at our figures in FotRSU - but I do remember is was NOT scientific by any stretch of the imagination... We considerably shortened the "Maximum Aircraft Range" to less than 1000km - Stock is 2000km - made a "world" of difference... sorry for the pun...
