U.S.S. Cimarron (AO-177) was the lead ship of the Cimarron-class of fleet oilers of the United States Navy. Cimarron was built at the Avondale Shipyards in New Orleans, Louisiana (USA) starting in 1978 and was commissioned in 1981 for service in the Pacific Fleet. Total cost for the ship was $136.7 million. Between 1989 and 1991 Cimarron was "jumboized", meaning that, after cutting the ship into two sections after about a third from the bow, a 35.7 m long section was added to increase the fuel load. Cimarron was decommissioned in 1998. She was struck from the Naval Vessel Register the following year and her title was transferred to the Maritime Administration. On 26 January 1999 she departed Pearl Harbor under tow and was placed in Susuin Bay, California, with the National Defense Reserve
