I am in no way near to being a WW2 submarine expert, I’m just here enjoying the fun. Now I was just recently reading a book on German subs and in it was a vintage torpedo room picture showing the crewman sitting on and around a torpedo, one of them had a special wench and looked like he was turning something on the torpedo. The picture’s caption said “German adjusting torpedo’s gages”
Now did they have to do this every time the target changed and then shove the fish into the tube,? How did the info from these "Whiz Wheels" get to the torpedos, before they went into the tubes or after, if after, how?
