The USS Cimarron (AO-177) was a fleet oiler in the United States Navy, primarily tasked with refueling ships at sea. This capability allowed naval vessels to remain operational for extended periods without returning to port, enhancing the effectiveness of naval operations. During its service, the Cimarron supported various military missions, including those during the Vietnam War and Operation Desert Shield. Its role was crucial in maintaining the readiness of the fleet, ensuring that ships could conduct sustained operations while receiving fuel, supplies, and other logistical support directly from the oiler.
