CVA 58 United States
CVA-58 美國號(United States) 航空母艦
原文 :
After several years of planning, on 29 July 1948 President Truman approved construction of a "supercarrier", for which funds had been provided in the Naval Appropriations Act 1949. This first postwar carrier was laid down in April 1949. The flush-deck 65,000-ton CVA 58 United States was designed to launch and recover the large aircraft of 100,000 pounds required to carry early nuclear weapons, which weighed as much as five tons. The ship was to be over 1000 feet long, without an island, and of a radical new design. The construction cost of the new ship was estimated at $190 million, with the additional thirty-nine ships required to complete the accompanying task force estimated to cost $1.265 billion. The United States was also intended to provide tactical air support for air and amphibious forces and to conduct sea control operations. But the general perception was that the United States was primarily intended as a platform for long-range nuclear bombardment.
The Air Force viewed the United States as the embodiment of the Navy's nuclear aspirations as an attempt to challenge what had been an effective Air Force monopoly on strategic nuclear weapons delivery. A majority of the JCS maintained that the super carrier旧 main function would be a duplication of the primary role of the Air Force. In the face of limited budgetary resources, and responding to opposition from the Army and Air Force, Defense Secretary Louis Johnson announced on 23 April 1949 the cancellation of construction of the United States. This prompted the immediate resignation of Navy Secretary John Sullivan. |
