The Mark 11 torpedo was the first American torpedo to be designed totally within the United States Navy without collaboration from industry.[1] It was developed by the Washington Navy Yard in Washington, D.C. and the Naval Torpedo Station in Newport, Rhode Island. The Mark 11 torpedo was also the first to feature a three-speed setting capability while tube-loaded: high at 46 knots, medium at 34 knots and low at 27 knots. Due to stability problems it was supplemented by the Mark 12 torpedo within two years, which had a 44-knot high speed setting.
