Trev - he's using that already. His problem is depth keeping at low speed below 170/180m. I assume you're thinking of this post: http://www.subsim.com/radioroom/show...7&postcount=93

However - even with TDWs mod, you have to do 2-4 kts to maintain depth below 170, and that's too fast for IRAI - they hear anything above about 1 kt, so going deeper than 170 (risking crush) to avoid cans ends up being counter-productive: you make more noise than if you'd stayed at 160 or so, and they hunt you down all the harder.

I've never been able to figure out how historically accurate this effect is. I understand that buoyancy should drop below a certain depth (I think), but I also assume subs would have gone lower than 170 in some circumstances (and survived). Any history buffs have anything to weigh in?

I think in SH4 I can hold depth well below test depth at 1kt - whether that's realistic or not, I couldn't say. At the moment in 5 (with IRAI), there's no point - stay above 160/70 and be quieter, or go below that and be a lot louder. You can't win
