Pinnebog was laid down, 29 December 1944, as a Maritime Commission type (T1-MT-M1) tanker hull, under a Maritime Commission contract, at Cargill, Inc., Savage, Minnesota. She was launched on 12 May 1945 and commissioned Pinnebog (AOG-58), 20 October 1945.
After serving with the U.S. Navy for 3½ years as a gasoline tanker, Pinnebog was placed out of commission in reserve 2 May 1949 in the Texas Group, Atlantic Reserve Fleet.
Reactivated, she was assigned to MSTS in March 1952 and operated under contract with a civilian crew until July 1954, when she was again placed in reserve, berthed in Florida. She was transferred to the Maritime Administration 20 April 1956 and to MSTS 23 April 1956.
She was then operated by an MSTS civil service crew until September 1957, when she was loaned to the U.S. Air Force.
Pinnebog was struck from the Naval Register (date unknown) and custody was transferred to the Maritime Commission, 15 December 1987. She was scrapped on 18 April 1988.
