Victory ships were a class of cargo ship produced in large numbers by American shipyards during World War II to replace losses caused by German submarines. They were slightly larger, more modern design when compared to the earlier Liberty ships, with a more powerful steam turbine engine allowing them to join high speed convoys and to make a more difficult target for German U-boats.
A mobile tracking platform for recording data on missiles and satellites that are out of range of established land stations, Range Tracker was homeported at Port Hueneme, California, on the Pacific Missile Range from June 1961 to 1969.
USNS Range Tracker's inertial navigation system monitored astronautGordon Cooper's 22-orbit space flight during July 1963.
Out of service
In 1969, when the Air Force Systems Command no longer needed Range Tracker, she was placed out of service at Port Hueneme 27 September 1969; transferred to the U.S. Maritime Administration 12 November 1969; and laid up at Suisun Bay. On 10 July 1970, she was sold to American Ship Dismantlers, Inc., for scrapping.
