About USNS Marine Adder

USNS Marine Adder (T-AP–193) was a troop ship for the United States Navy in the 1950s. She was built in 1945 for the United States Maritime Commission as SS Marine Adder, a Type C4-S-A3 troop ship, by the Kaiser Company during World War II. In 1950, the ship was transferred to the Military Sea Transport Service of the U.S. Navy as a United States Naval Ship staffed by a civilian crew. After ending her naval service in 1957, she entered the National Defense Reserve Fleet, but was sold for commercial use in 1967. She was used in part to carry supplies to support the Vietnam War efforts. During the Summer of 1972 while in Da Nang Port, South Vietnam, a limpet mine was attached to the vessel by a swimmer, blowing a hole in the hull upon detonation. In order to save the ship, the Skipper ran it aground in the Da Nang harbor.
