Short Mark 7 torpedo
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, 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.
