1951. During this time she spent a month at Taiwan fueling the ships on duty in the Formosa Straits, and made three voyages to Korean waters from Sasebo. During 1952, overhaul and training on the west coast preceded her third Korean war deployment from 9 April to 5 January 1953, when her duty was similar to that of her second. Her fourth tour of duty in the Far East was completed between 11 April and 27 November 1953. Cimarron sailed to the Far East again between 14 June 1954 and 8 February 1955, during which she served as flagship of the United Nations support group for Operation Passage to Freedom, the evacuation of refugees from Communist North Vietnam. Her pattern of operations from that time into 1963 included highly effective support of the guardian U.S. 7th Fleet in its Far Eastern operations through deployments in 1955, 1956-1957, 1957-1958, 1958-1959, 1959, and 1960. As of 1963, she had the longest continuous commissioned service of any active ship in the United States Navy, belying her age as she continued to provide her essential support with outstanding skill and efficiency. Vietnam War Cimarron continued her service into the Vietnam War between 1965 and 1967 and received the Armed Forces Expeditionary Medal and Vietnam Service Medal for its participation in the Vietnam Advisory Campaign, Vietnam Defense, and Vietnamese Counteroffensive Phases I through III.

The bell from the ship was installed at Cimarron High School in Cimarron, New Mexico, where it was donated because of its proximity to Cimarron River Basin's headwaters and in recognition of this ship's dedicated crew members.
