I was going to ask if anyone knew at what depth point a Type VII would start to feel the limits of buoyancy. Is it 100m? 300m? 1000m? Maybe modern subs have sealed main ballast tanks but the WWII variety had permanently open bottoms like an upside down drinking glass so the volume of air contracts as the ambient sea pressure increases.

I hear now with SH5 we have a scripting system so depending on how powerful that is we can run a very sophisticated arrangement of depthkeeping. Perhaps we can even get to the point that we can tell our engineer how conservative to make his trim and torpedoes upset the balance when fired.
