Caney sailed from San Pedro, California, on 12 May 1945 for Ulithi, the base from which she operated while fueling ships serving on radar picket and patrol duties at Okinawa.

From 3 July through the end of the war, she steamed with the logistic group supporting task force TF 38 in its bombardments and air strikes pounding the Japanese home islands.

The oiler remained off Okinawa serving ships engaged in occupation duty until 16 November, when she got underway for San Francisco, California, and Galveston, Texas.

Reacquired by the Navy in February 1948, she was transferred to the Military Sea Transportation Service on 18 July 1950, where she served as USNS Caney (T-AO-95) in a noncommissioned status with a civilian crew.

Caney was acquired by the United States Army in 1966 and converted at Bender Shipbuilding and Repair Co., Mobile, Alabama, into a floating power station for Vietnam service.
