General G. O. Squier-class transport

The General G. O. Squier class of transport ships was built for the U.S. Navy during World War II. The class was based upon the Maritime Commission's Type C4 ship. The class was named for United States Army Major General George Owen Squier.[1][2]

The first ship was launched in November 1942, while the last was launched in April 1945. Over that period the United States produced 30 General G. O. Squier-class transports. All of the ships were initially designated with hull classification symbol "AP" and numbered from 130 through 159. All but the four ships of the class (130, 131, 132, and 136) were transferred to the U.S. Army Transportation Service in 1946 and served as United States Army Transports (USAT), several of them being refitted to a larger gross tonnage. The 24 (numbers 134, 135, 137–151, and 153–159) still in service in 1950 were transferred back to the Navy as part of the Military Sea Transportation Service (MSTS). All but two were transferred on 1 March 1950,[3] and all were reinstated on the Naval Vessel Register as United States Naval Ships (USNS), and redesignated with hull classification symbol "T-AP".[4]

Most of the General G. O. Squier class were deactivated in 1958 for two reasons: the introduction of jet airliners, and a decision to use berthing space on U.S.-flagged passenger ships.[5] Two ships, however, General LeRoy Eltinge and General R. M. Blatchford, assisted in United Nations efforts in the Congo Republic in the early 1960s, and both were pressed into service transporting troops to Vietnam in the mid 1960s.[6]

Two other ships of the General G. O. Squier class, General Harry Taylor and General R. E. Callan were transferred to the U.S. Air Force as missile tracking ships as part of the Missile Test Project, and renamed USAFS General Hoyt S. Vandenberg and USAFS General H. H. Arnold, respectively. They were later transferred back to MSTS under their new names and redesignated with hull classification symbol "T-AGM".[7]

The last General G. O. Squier-class ship afloat, the ex-General Hoyt S. Vandenberg, was sunk as an artificial reef off of the Florida Keys on 27 May 2009.[8][9] [10]
