I was just doing some testing on my attempt at activating that, and first shot "The torpedo is a dud, sir." Nothing... lol - no splash, so I either did something wrong (highly likely), or I'm missing something still (also highly likely), or the game needs something else (possible). Anyway, shots 2-6 did NOT DUD!!! what the? A 90 degree shot in FotRSU with duds enabled should render you a 99% chance of a dud in early 1942... sigh.
