I know different types of torpedoes were used in WW2 (contact, proximity (?)), and the answer to my questions might differ depending on type. What happens to the torpedo if it misses its target? It must sink eventually, but is there a timer mechanism to render it "safe" if it runs out of fuel or does not detonate within a certain amount of time? If this is not the case, there must be armed torpedoes on the sea bottom? Thx
Check out the torpedo pates here: Naval Weapons of the World - NavWeaps In most casers torpedoes that missed just sank after their fuel ran out. Lots of torpedoes, mines, and shells on the bottom of the sea. The seas a big place though.
AFAIK, all American torpedoes detonated at the end of their runs. This is mentioned in several books written concerning submarines experiences and in their ear patrol reports. I believe that this was done to ensure the destruction of the Mark 6 exploder. Some other navies had their torpedoes flood and sink at the end of it's run. The Japanese Long Lance was only found out about in 1943, when one ran up on a beach and was captured by the Americans.
