USS Sphinx
USS Sphinx (ARL-24) was laid down as a United States Navy LST-542-class tank landing ship but converted to one of 39 Achelous-class repair ships that were used for repairing landing craft during World War II. Named for the Sphinx (a mythical monster formed by joining the body of a lion and the head of a human), she was the only US Naval vessel to bear the name.
Originally authorized as LST-963, the ship was redesignated as a landing craft repair ship (ARL) and named Sphinx on 11 September 1944; laid down 20 October 1944, at Hingham, Massachusetts, by the Bethlehem-Hingham Shipyard; and launched on 18 November 1944. She was placed in partial commission for ferrying to her fitting out yard, the Merrill Stevens Drydock, Jacksonville, Florida, 12 December 1944. Decommissioned 8 January 1945, for fitting out, she was recommissioned Sphinx (ARL-24), 10 May 1945.
Sphinx completed fitting out and proceeded to Norfolk, Virginia for sea trials and shakedown in Chesapeake Bay. On 12 June 1945, Sphinx sailed for the west coast; transited the Panama Canal on 23 June; and proceeded via San Diego to San Francisco. She was assigned to the Amphibious Forces, US Pacific Fleet, and ordered to Hawaii. Sphinx arrived in Pearl Harbor, on 31 July, and repaired craft there until 27 August, when she sailed for Adak, Alaska.
Before she reached Adak, her sailing orders were modified, routing her to Japan. She arrived at Mutsu Bay, Honshū, on 14 September, and began repairing and refitting minesweepers. Sphinx moved to Yokosuka, on 20 November, and sailed for Saipan, on 3 December 1945. She operated in the central Pacific islands until entering Pearl Harbor, on 9 January 1947, en route to the west coast for decontamination. The ship had participated in "Operation Crossroads," the atomic bomb tests at Bikini Atoll, in the Marshall Islands, from early April to 29 August 1946.
Sphinx arrived at San Pedro, Los Angeles, on 22 January, where she was decontaminated and prepared for inactivation. She was placed out of commission, in reserve, on 26 May 1947.
The outbreak of hostilities in Korea created a need for Sphinx's repair facilities in the Far East. She was recommissioned on 3 November 1950. After outfitting and holding shakedown training, she stood out of San Diego, on 17 August 1951, and proceeded via Pearl Harbor to Japan. Sphinx arrived at Yokosuka, on 29 September, and operated from Japanese ports until 7 May 1952. During this time, she repaired and serviced fleet units that were being used in Korea. The ship returned to San Diego, on 4 June 1952, and operated along the California coast until redeployed to the Far East from 3 March to 9 December 1954. Sphinx operated along the west coast during 1955, and on 31 January 1956, was again placed out of commission, in reserve, and berthed at San Diego.
In January 1967 orders were issued to reactivate Sphinx for use in Vietnam. She was towed to New Orleans, Louisiana, in February, and on 16 December 1967, placed in commission. The ship sailed for the west coast on 8 January 1968, and arrived at San Diego, on 23 February. On 22 April, Sphinx and Cohoes sailed for the western Pacific. The ships made port calls at Pearl Harbor, Kusaie, Guam, and Subic Bay. Sphinx sailed independently from there on 6 June, and four days later, arrived at Vũng Tàu, South Vietnam. Sphinx moved to Dong Tam Base Camp, on 11 June, and was assigned to the Mobile Riverine Force in the Mekong Delta. Her unit was Task Force (TF) 117 composed of 11 shallow-draft ships and over 150 river assault boats. The repair ship was on a non-rotating basis and, during 1969, had very little time underway. She operated in the Tien Giang and Ham Luong rivers, providing service and support for the river boats as they engaged in operations against the Viet Cong. The ship sailed from Vietnam, on 21 June, for a yard period at Sasebo, and returned on 25 August.
Upon her return to Vietnam, Sphinx operated along the Vam Co River. In addition to her regular duties, the ship served as the tactical operations center of the Can Giuoc Interdiction Unit and also developed helicopter capabilities, handling 50 landings before 31 December 1969. She remained in Vietnam, until 14 December 1970, when she weighed anchor for a yard period at Yokosuka. On the last day of the year, the ship lost power in both main engines and was adrift 340 mi (550 km) from Sasebo. On 2 January 1971, USS Chipola took her under tow for Sasebo where she was repaired.
