I've been playing submarine sims since the days of Silent Service.
You have to be pretty dumb to attack a task force on purpose.
Dive deep, go quiet and head in the opposite direction preferably into deeper water with your fingers crossed that you haven't been spotted..
I never attack more than two and only if they are heading for me in a straight line,whilst I'm at scope depth, rigged for silent running.
