That explains a lot. Warships of course have damage control crew (in Real life) so they can be made harder to sink artificially to get a realistic result.

I posted this in my making AAA dangerous to subs thread, and now it makes more sense to me, perhaps it might help in your studies of this:

Hmm. This is very very interesting.

So I dialed the damage down (for 20mm damage mod---made min ~5 to 8 and max ~10). The radius, too. 20mm AP I gave a radius of... 20mm, for example. Others have damage radius 0.02 to 0.4 or so.

Sub is getting hammered for a while. So far so good. I put the skipper below near the chart thinking my spinning death cam might have been "me" on deck getting killed. Below, there are leaks everywhere. Check damage. NOTHING on DC screen. Go back below. More leaks. Lights start blinking. Lights go out. We start taking flooding.
I look at the DC screen. compartments start to flood, stern to bow. flood, systems all go red (water part way up, not total flooding) in that compartment. Next floods, same, then next, then next, all the way to bow, spinnign death cam follows.

I assume what's going on is that the 20mm I made is not actually doing internal damage, but IS taking away hitpoints. At some point, the hitpoints get used up, and the compartment fails totally.

This would actually explain a lot of myster deaths people get. You duke it out with planes, or whatever, and get hit with loads of AAA. No crew are hurt (ever) so there is no reason to avoid autocannon. No damage is ever done---THAT YOU SEE---so you assume all is well. Head towards max depth to avoid ashcans... domino effect.

I'm not sure what yo do. If you make 20mm so it can do any real damage, there is enough of it flying the hitpoints are likely very low. Drop it below the amount that it shows damage to systems without wiping out the whole compartment, and you never know you are damaged until the hull fails catastrophically.
