Mark 37 Electric Torpedo


Mark 37 Electric Torpedo, originally uploaded by cliff1066.

The Mark 37 torpedo is a torpedo with electrical propulsion, developed for the US Navy after World War II. Its engineering development began in 1946 by Westinghouse-ORL. It was based on the active homing system tested on modified Mk-18 torpedoes, with added passive homing and a new torpedo body. Between 1955-56, thirty torpedoes were produced for development testing, with large-scale production commenced shortly later. Due to its electric propulsion, the torpedo swam smoothly out of the launch tube, instead of having to be ejected by pressurized air, therefore significantly reducing its acoustic launch signature
