USS United States

USS United States (CVA-58) was to be the lead ship of a new design of aircraft carrier. On 29 July 1948, President Harry Truman approved construction of five flush deck "supercarriers", for which funds had been provided in the Naval Appropriations Act of 1949. The keel of the first of the five planned postwar carriers was laid down on 18 April 1949 at Newport News Drydock and Shipbuilding. The program was canceled in 1949, United States was not completed, and the other four planned carriers were never built.
