The MK-14 torpedo was developed in the 1930's on a very meager budget. These torpedoes were successfully deployed during World War II, destroying more than four million tons of Japanese shipping.

Early in the war the MK-14 proved to be very inaccurate and often failed to explode on impact. By mid-1943 frantic research and testing had corrected the depth control and the exploder unit design, making the MK-14 submarine torpedo a very reliable weapon.
