USNS Sgt. Jack J. Pendleton (T-AKV-5 /T-AK-276) was a Lt. James E. Robinson-class cargo ship constructed during World War II as a Victory ship and named the SS Mandan Victory. The Mandan Victory was placed into service by the War Shipping Administration's Emergency Shipbuilding program under cognizance of the U.S. Maritime Commission. In 1973, while sailing in the Paracel Islands, Sgt Jack J. Pendleton struck a reef off Triton Island. Attempts to remove her from the reef failed, and she was abandoned.
