That depends if you lost hull integrity or not. I've seen two kinds of close end ash cans. One tends to cause some damage to the bulkhead and cause some flooding for a time, but leaves the hull integrity alone.
Thats fine in my book. Adds some realism i think. I like the idea of incurring repairs and flooding while under attack. Im technical game terms, it damaged the bulkhead equipment item and leaks started.
The other causes hull integrity loss. Those are the fatal ones, and ive seen those in testing too.. Generally speaking a depth charge in real world terms has to be very close to crack a hole in the "people tank."
As an aside you may find these
damage reports interesting.
