History
The Mark 14 torpedo was introduced into the navy in 1929. The warhead contained 507 pounds of TNT with a contact exploder.

During next 60 years this class underwent 6 modifications. The warheads were upgraded with 668 pounds of TPX and 600 pounds of TPS respectively and maintained the contact exploder.

It was taken out of service in 1959 and reinstated in 1969. In the late 1970’s it was withdrawn from service.

During World War II, the U.S. Navy submarines sank more shipping tonnage with the MK 14 Torpedo than all other sources combined.
