I just had an experience that makes me think the ballast tank theory is correct. After a desperate surface battle with some destroyers (which I won), I realized I couldn't turn any more, even though there was no damage to the rudder in the DC screen. With the external view, I saw the rudder was missing, presumably blown off.
Now, that damage was there, visible in the outside, but not in the damage control screen. I managed to reach an advanced base (exploiting a save-load bug to turn), and refit, but the rudder was still missing, even though other destroyed items were fixed.
I suspect now that damage to certain exterior items of the sub is modelled correctly, maybe including the ballast tanks, but that damage a) is not displayed anywhere (except in the physical model, and how would you tell a damaged tank apart?) and b) is not repairable. Sounds like a bug to me...
