Indeed and that would make a wake less airdropped torpedo a moot point if ever there was one.The only electric airdropped torpedo that I am aware of is the Mk.24 "Fido" and that was a small device (for a torpedo) and had a low top speed and a small warhead.Of course it was used against U-boats that would be in the process of diving or submerged and not be able to out run the "Fido".

The Japanese air torpedoes where kerosene-air powered so they also left a wake.Japanese ship and submarine launched torpedoes kerosene-oxygen powered.
