One important point, however. For whatever the reason, if the deck gun or flak guns get damaged in a depth charge attack, then the crew currently assigned to the gun will also be injured or killed, even though the boat is underwater and the guns aren't manned. I've taken to keeping the gunners in the damage control station until I need them, then manually moving them.
