Tried a blind attack last night and what a rush! Heavy fog, 2nd or 3rd hit on a convoy so I knew speed and course and that they were Nips. Sunk down to 349' and waiting using only the hydrophones until they sounded close. Popped up to 90' just as they were arriving (350' to 90' takes 3:00 in the Gato) and unleashed a spread of 6 torps on a single target.
I picked the loudest sound contact and only used 3 pings for range to confirm it wasn't 200 miles away (2,000 yrds and 20,000 yrds sound so similar on the phones).
Immediately dived back down to 350' after launching and listened. 2 hits, 1 dud, and 3 misses. Sank a 7400 ton merchant without ever seeing it! Probably wouldn't anyway in the heavy fog. The escorts had exactly 0 idea what was going on. No pings or DCs at all.
I'm hooked on this method for poor weather shooting. Saves tons of time on the evading end of things plus avoids you getting run over in the fog. Lots of times in heavy fog I can just barely make out the outline of a ship before I get inside minimum range anyway. I may even start doing it for fair weather shots. I'm going to have to look up the torpedo spread info in the .pdf manual again. 6 sounds like too many unless it's a tanker.
And it's historical
