maintaining depth at stop

so think about it, if you were the skipper and you life depended on stealth, would you rather have negative boyancy so your sub sinks at all stop or positive boyancy so your ship will rise at all stop and get your head blown off.

positive or negative boyancy is not designed in, it is a setting chosen by the captain. plus if you want to dive faster like all subs do, then positive boyancy is going to be fighting you as you try to dive.

IMO all subs made sure they were at some level of negative boyancy any time they werent surfaced

I completely see your point, but on the other hand, if something goes badly wrong, I wouldn't want to sink to crush depth either.
