DC announcement ?
If you mean "depth charges in the water " then you will get those even if the DD is dropping them a few hundred yards away

Sure when you are first learning it helps to see what your torps are doing but after that tis a PITA
Every ships sinking\aircraft attacking and DC falling close it appears
Esp bad when you are using snorkel and the window pops up to show an aircraft in attack run
