USNS Private Leonard C. Brostrom (T-AK–255) was a cargo ship for the United States Navy that was converted into a heavy lift cargo ship in the early 1950s. She was built in 1943 for the United States Maritime Commission as SS Marine Eagle, a Type C4-S-B1 tank carrier, by Sun Shipbuilding during World War II. In 1948, she was transferred to the United States Army as USAT Private Leonard C. Brostrom after Leonard C. Brostrom, a recipient of the Medal of Honor. 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, she entered the National Defense Reserve Fleet in October 1980 and was sold for scrapping in June 1982.
