The Short Mark 7 torpedo was a variant of the Bliss-Leavitt Mark 7 torpedo developed by the Washington Navy Yard in order to fit certain submarine torpedo tubes in 1917. The Short Mark 7, also designated Torpedo Type D,[2] had an air flask that was shortened and a reduced warhead weight. The fuel and water tanks were relocated to obtain more air flask capacity; the fuel tank was mounted in the aft air flask bulkhead, while the water tanks were mounted in the after-body. The overall weight of the warshot torpedo was 590 pounds lighter and 58 inches shorter than the Mark 7. The air, fuel and water capacities were approximately one-third of the capacities found on the full-size Mark 7. This torpedo was never produced in quantity.[1]
