List of aircraft carrier classes of the United States Navy

On November 14, 1910, pilot Eugene Burton Ely took off in a Curtiss plane from the bow of Birmingham and later landed a Curtiss Model D on Pennsylvania on 18 January 1911. In fiscal year (FY) 1920, Congress approved a conversion of collier Jupiter into a ship designed for launching and recovering of airplanes at sea—the first aircraft carrier of the United States Navy. More aircraft carriers were approved and built, including the Ranger, the first class of aircraft carriers in the United States Navy designed and built as aircraft carriers from the keel.

The United States declared war on Japan following the attack of 7 December 1941 on Pearl Harbor. The two nations revolutionized naval warfare in the course of the next four years; several of the most important sea battles were fought without either fleet coming within sight of the other. Most of the fleet carriers were built according to prewar designs, but the demand for air protection was so intense that two new classes were developed: light carriers (designated CVL), built on modified cruiser hulls, and escort carriers (CVE), whose main function was to protect Atlantic convoys from German U-boats.

During the postwar period, carrier technology made many advances. The angled flight deck was adopted in 1955. The first "supercarrier" was commissioned in 1955 (although an earlier plan had been canceled by the Secretary of Defense), and the first nuclear-powered carrier in 1961, all during the Cold War. Also, a record for crossing the Pacific Ocean was set by a U.S. Navy carrier during the Korean War. Carriers recovered spacecraft after splashdown, including the Mercury-Redstone 3 and Apollo 11 missions.
