Convair YF2Y-1 Sea Dart 135763 US Navy
The Sea Dart was to be the first combat-type plane equipped with retractable hydroskis, the first delta-winged seaplane, and the first supersonic seaplane in the world. Its first flight was made over San Diego Bay on April 9, 1953, and in August 1954, the plane proved its supersonic capabilities. However by 1956, tactical doctrine had changed and the Navy abandoned the seaplane fighter concept and, with it, the Sea Dart program. | picture Tom Warnock
