The experimental phased array radar was first installed on the island, and then it was dismantled in the reconstruction of 1978- 1992. The ship was built by Newport Shipyard, started on February 4th, 1958, was launched on September 24th,1year, and entered service on October 25th. Oil was supplied at 1965; 1969 65438+1October 14, an accidental fire and explosion occurred in Hawaii, and the tail was basically damaged. The explosion caused by the fire blasted five holes in the flight deck. The second oil supply is in 1969- 197 1 year. On June 30th, Kloc-0/975, it was redesigned and refitted into a multi-purpose aircraft carrier, and then refitted to operate an anti-submarine aircraft. From 1979 to 1982, fuel supply and modernization were carried out at Bremerton Naval Shipyard. The island superstructure was rearranged and the sea sparrow ship-to-air missile was installed. From June 1990 to1October 12 to September 23, 1994, it was overhauled and refueled at Nur Bonus Shipyard. It is planned to serve until 20 13, and will be replaced by CVN78 in the future. American nuclear-powered aircraft carrier enterprise is the first nuclear-powered aircraft carrier in the world. 1964, Enterprise made an unprecedented voyage around the world, which lasted 64 days without refueling and replenishment, and the total voyage exceeded 30,000 nautical miles, fully demonstrating the great endurance of nuclear power. Its design and construction have an important influence on the Nimitz class of the second generation nuclear-powered aircraft carrier in the United States. 1970, replacing nuclear fuel for the second time after sailing for 300,000 nautical miles. 1979—— 1982, the "enterprise" changed its nuclear fuel for the third time during its 38-month modernization modification. In the 1990s, the Enterprise was modernized and its nuclear fuel was replaced for the fourth time. After more than three years of engineering, 1995 was put into use again. The budgeted cost of Enterprise in the fiscal year of 1958 is 450 million US dollars, and it needs 64 million US dollars to fill the nuclear fuel for the first time and 20 million US dollars to replace the nuclear fuel. According to 1990 fiscal year, the latest modification project is allocated1400 million USD. The Enterprise was deployed in the Pacific Fleet during its service. During the Vietnam War, the aircraft on the Enterprise participated in the bombing of Vietnamese targets, which was the first time in history that a nuclear-powered aircraft carrier participated in the war.

Kennedy and was nicknamed "Big John" by the military. During the Cold War, Kennedy's first overseas mission was to go to the Mediterranean region to contain the expansion of Soviet forces. 1989, the United States is hostile to Libya. F- 14 fighter planes taking off from Kennedy shot down two Libyan MiG -23 fighters. The most important overseas military operations it participated in were "Desert Shield" and "Desert Storm" in 1990s. At that time, he led an aircraft carrier battle group from the Mediterranean to the Red Sea and became the flagship of the commander of the US "Red Sea Combat Force". The aircraft carrier Kennedy was originally designed and built as a Nimitz-class nuclear-powered aircraft carrier, but due to the appearance of anti-ship missiles at that time, large ships were vulnerable to anti-ship missiles. Under the pressure of the US Congress, the Kennedy had to be changed into a conventional power carrier with smaller tonnage and lower cost. It was not until the Vietnam War that the United States approved the construction of a larger Nimitz class. The influence "Kennedy" is the last aircraft carrier of "Kitty Hawk" class, with the ship number CV67. According to the plan, "Kennedy" will go to Norfolk Naval Base in Virginia for the second phase of maintenance in 2005, and then will continue to serve until 20 18.
