that is fairly common. ussually it happens in a crowded area, when a destroyer has to slow down to avoid a collision.
there was a mod that replaced the nuclear depth charges with ones that didnt blow up everything in a 3 mile radious. not sure what it was, but it reduced the unbleievable reach of depth charge blast.
and that one also stopped the destroyers popping like baloons too.
as it stands depth charges cause damage over something daft like 100 feet. meaning that if your at periscope depth, the destroyer will kill itself unless its moving when it drops the charges.
because it doesnt drop them deep enough to avoid theyre reach so to speak.
the damage they do is fine, but its the crazy reach of the things. ive had them go of two sub lenghts behind me and a sub lenght to the side. and died before
