I'm all for the realism of not letting surface ships know if a sub's been killed, unless, as has been mentioned earlier, blast the bejeezus out of 'im. >:( I'm a surface driver, myself, and while I do like knowing if I have indeed killed the sub, it would add a lot more of a "cat and mouse" aspect to the whole thing in MP. This would allow subs to escape sometimes because a surface ship would be needed elsewhere and they couldn't stick around to see if they got the kill. On the flip of that, if a surface ship is needed elsewhere and they DO stick around to see if they got the kill, and the sub's been dead for 20 min, that sub is still aiding his country while dead, in a tactical sense. (Although a surface captian that sticks around for one sub that long is an idiot, especially when you realize that, given the probable length of the fight before the sub was suck, the sub ran out of air a while ago...)
All in all, I think realism is the way to go in this case, even if it would be another disadvantage for me.
Subs realistically have everything going for them in the stealth department, and unless stealthy tricks are possible, you're really taking their strength away from them and making them play to the sub hunter's strength.
Oh, and btw, Kadreal, depending on depth, the surface ship would hear the compressed air used to launch your torp. At least, I hope so if I'm the surface ship above you.
