USS Ajax (AR-6) was a Vulcan-class repair ship commissioned by the United States Navy in October 1943. During World War II, she provided vital repair and maintenance services to the Pacific Fleet, supporting operations in locations such as Eniwetok, Ulithi, and Okinawa. Ajax continued her service through the Korean War and the Vietnam War, ensuring fleet readiness by repairing and refitting ships close to combat zones. After decades of service, she was decommissioned in 1986, marking the end of a distinguished career supporting U.S. naval operations across three major conflicts.
