Korean War

Kearsarge recommissioned on 15 February 1952 with Captain Louis B. French in command. Following shakedown, the carrier cleared San Diego on 11 August for intensive flight training in the Hawaiian Islands. Her readiness complete, she sailed for the Far East to engage in combat missions in the Korean War. Arriving at Yokosuka on 8 September, Kearsarge joined the fast carrier Task Force 77 (TF 77) off the east coast of Korea six days later. For the next five months, the carrier's planes flew nearly 6,000 sorties against Communist forces in North Korea, unleashing considerable damage on enemy positions. She completed her tour in late February 1953, returning to her home port of San Diego on 17 March. While serving in Korea her classification was changed to CVA-33.

After returning to San Diego, Kearsarge was used in the filming of the 1954 movie The Caine Mutiny to depict the abortive visit to Admiral William F. Halsey Jr. aboard his unnamed flagship.

Far East

Kearsarge sailed again for the Far East on 1 July 1953 and operated with the 7th Fleet fast carrier force during the uneasy truce in Korea. The "Mighty Kay" (after three collisions with other ships in a short period of time, including the ocean liner SS Oriana, Kearsarge was also nicknamed by some "Rammin Rankin's Krashbarge" and "The Mighty Kay-RUNCH") also kept watch over the Formosa Straits to prevent the Communists from attacking the Chinese Nationalists on Taiwan. Kearsarge returned to San Diego on 18 January 1954 to resume training operations off California. Clearing San Diego on 7 October, she steamed toward her third deployment to the Far East. While operating with the 7th Fleet, the carrier stood by to assist the Nationalist Chinese in the evacuation of the Tachen Islands. From 6–13 February 1955, Kearsarge supported units of the fleet in the successful evacuation of 18,000 civilians and 20,000 military personnel from the islands. Her cruise ended at San Diego on 12 May and for the next three years operated on the annual deployment schedule to the Far East and training operations off California.

In 1956–57, Kearsarge received the SCB-125 modernization, mainly incorporating a hurricane bow and an angled deck.

During the summer of 1958, Kearsarge was fitted out as a(n) (antisubmarine warfare) support carrier and reclassified CVS-33. Following intensive training in her new role, the carrier sailed on 5 September 1959 for 7th Fleet operations in the Far East. Early in her tour, Japan was hit with a violent typhoon, and Kearsarge played an important role in providing relief to the victims. Her planes landed parties of medical and supply units, while her crew and air group donated clothing and money to the distressed people. After participating in SEATO exercises and 7th Fleet operations, she cleared Yokosuka on 3 March 1960 for her homeward voyage. Three days later in stormy waters 1,200 miles (1,930 kilometers) off Wake Island, four Russians were rescued after drifting 49 days in disabled landing craft. They were flown back to their country after Kearsarge arrived in Alameda, California, on 15 March; and the carrier received thanks from the Soviet Union for this gesture.^{[2][3] [4][5]}

A year of training operations preceded her next deployment from San Diego which began on 3 March 1961. The antisubmarine carrier steamed to Southeast Asian waters as the Communists intensified their effort to overthrow the government in Laos. The demonstrations of the 7th Fleet were observed by the enemy and the crisis abated. After six months in the Far East, Kearsarge arrived Puget Sound on 1 November for the second phase of her modernizations.

Project Mercury

Upon completion of repairs and training, Kearsarge departed Long Beach, California, on 1 August 1962 to station herself in the Western Range as a recovery ship in the Project Mercury orbital space flight of astronaut Walter Schirra after splashdown. On 3 October, after a flawless flight, the carrier played her role in the Space Age by retrieving Schirra and his space capsule, Sigma 7, and returning him to Honolulu for flight back to the mainland.

Kearsarge resumed training exercises, continuing these for six months before arriving Pearl Harbor on 29 April 1963 to once again take part in the space program. The carrier repeated her earlier splashdown recovery by plucking astronaut Gordon Cooper on 16 May 1963 after he orbited the Earth 22 times in his capsule Faith 7.

Vietnam

She returned the space hero to Pearl Harbor, then departed on 4 June on her eighth cruise to the Far East. Operations with the 7th Fleet included keeping watch on the unsettled problems in Southeast Asia. Kearsarge returned to Long Beach on 3 December for training exercises off California.

On 19 June 1964, the antisubmarine carrier was deployed on her ninth Far Eastern cruise. Arriving Yokosuka on 30 July, Kearsarge was dispatched to the South China Sea, following the Gulf of Tonkin Incident, the North Vietnamese patrol boat attack on U.S. destroyers in the Gulf of Tonkin in early August 1964. While U.S. Navy planes destroyed North Vietnam oil and supply depots, Kearsarge provided antisubmarine protection for the 7th Fleet. Kearsarge returned to Long Beach on 16 December.

After overhaul during the first half of 1965, Kearsarge operated off the West Coast and appeared in a 1965 episode of Bob Hope Presents the Chrysler Theatre entitled "The Admiral," with a number of Douglas A-1 Skyraiders painted in Korean War-period colors on her deck for the production. She departed for the Far East on 9 June 1966. Steaming via Hawaii and Japan, she reached "Yankee Station" on 8 August and operated off Vietnam through 24 October. The next day she headed for the Kuala Lumpur area and anchored in the Strait of Malacca on the 30th. She returned via Subic Bay to "Yankee Station" on 5 November and operated there through the 23rd. The next day, the carrier started home via Hong Kong and Japan, arriving in San Diego on 20 December. She operated on the West Coast until departing San Diego on 18 August and reached Pearl Harbor 10 days later to prepare for future action.

Made redundant by the general fleet drawdown of the late 1960s and early 1970s, Kearsarge was decommissioned on 13 February 1970. Following three years in the Reserve Fleet, she was stricken from the Naval Vessel Register in May 1973 and sold for scrap in February 1974.
