USS ESSEX CV-9 began the first of three tours in Far Eastern waters during the Korean War. She served as flagship for Carrier Division 1 (CarDiv 1) and Task Force 77. She was the first carrier to launch F2H Banshees on combat missions; on 16 September 1951, one of these planes, damaged in combat, crashed into aircraft parked on the forward flight deck causing an explosion and fire which killed seven. After repairs at Yokosuka, she returned to frontline action on 3 October to launch strikes up to the Yalu River and provide close air support for U.N. troops. Her two deployments in the Korean War were from August 1951-March 1952 and July 1952-January 1953. On 1 December 1953, she started her final tour of the war, sailing in the East China Sea with what official U.S. Navy records describe as the "Peace Patrol". From November 1954-June 1955, she engaged in training exercises, operated for three months with the United States Seventh Fleet, assisted in the Tachen Islands evacuation, and engaged in air operations and fleet maneuvers off Okinawa.
