Thanks for the reply
Most would agree standard operating procedures are to "ahead flank" and full rudder when splashes are heard.
I always thought the charges were masking our subs, but your telling me its their own prop wash masking our escape??
"As I understand it, in SH3 the passive hydrophone stays operational all the time and it works perfectly even after a depth charge run destroyed the usable audio conditions completely for several minutes."
If i'm understanding correctly you're saying after a depth charge run (passive)phones are still working/running/operating but fruitlessly? kind of like a refigerator with its door left open?
Thanks again,
