Following a much-needed overhaul, Cahaba sailed from San Pedro, California, to the kamikaze-ridden waters off Okinawa, delivering oil to the station tanker at Kerama Retto late in June 1945.

Clearing Ulithi on 3 September, the oiler paused at Okinawa, then sailed on to Shanghai to aid in the reoccupation by Chinese Nationalists of areas held by the Japanese during the war.

Occupation duty at Okinawa, Formosa, Hong Kong, and Amoy continued until 16 March 1946, when she cleared for the Panama Canal and New York City, arriving on 28 April.

Reacquired in March 1948 and transferred to the Military Sea Transportation Service on 31 July 1950, Cahaba served in a noncommissioned status until 20 January 1958 when she was returned to the Maritime Administration.

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