During the remainder of the war she operated as a merchant ship under charter to Olympic Steamship Company, and she continued merchant service under bareboat charters from the Maritime Commission and the Maritime Administration until 1958 when she entered the National Defense Reserve Fleet at Olympia, Washington.
After conversion to a special projects ship by Triple "A" Machine Shop, Inc., San Francisco, California, Huntsville began duty as a range tracking ship in 1961.
Crewed by civilians, Huntsville operated out of Port Hueneme, California, and Honolulu, Hawaii, while assigned to special duties in the Pacific Ocean. During the next 4 years she made intermittent "on station" patrols in the Central Pacific, extending from the coast of Mexico to Wake Island and the Marshall Islands. She continued these patrols, which contributed mightily on America's space programs, until the spring of 1965; then she entered Avondale Shipyards, Inc., Westwego, Louisiana, 2 June 1965 for conversion, completed 30 October 1966.
In June 1967 Huntsville returned to the Pacific, where she operated with Watertown (T-AGM-6). As an improved sea-based tracking station, she provided an important link in communications during the scheduled "Apollo" moon shots, which were designed to send American astronauts to the moon and back.
Final Mission and Inactivation
One of the last missions for the Huntsville was in support of US surveillance of nuclear testing in the South Pacific. Huntsville spent approximately 90 days between June and September 1974 on that mission, most of it in the vicinity of Mururoa Atoll.
The following paragraph appeared in the Stanford Research Institute Alumni Newsletter in 2010 in an article by Walter Jaye entitled Adventures at Sea in the South Pacific.
"The Conclusion of the Missions:
In 1974, the third and final year of these operations, the ship used was the USNS Huntsville (see photo). The use of helicopters was dropped, and instead remotely piloted vehicles were launched from the Huntsville."
Huntsville was placed out of service on an unknown date, and was struck from the Navy List on 8 November 1974. She was placed in the National Defense Reserve Fleet and eventually sold by MARAD on 17 July 1995. Her subsequent fate is not known.
