U-Boats carried two different types of torpedoes.

  1. G7a:  powered by compressed air, which left the trail of bubbles, a popular scene in movies.
  2. G7e:  electrically powered torpedoes, which didn’t leave a trail of bubbles.

Improved versions of these torpedoes were issued to the U-Boat fleet in mid-1942. Subsequently torpedoes which homed in on the sounds made by a ship’s propellers was introduced. The Allies quickly came up with counter measures.
