The United States Navy held considerable interest in the submarine aircraft carrier concept during the late 1940s. A study performed in 1946 envisioned very large submarines, ranging from to in length, to carry two XA2J Super Savage bombers for the strategic nuclear strike mission, or alternatively four F2H Banshee fighters. Another proposal would have involved the conversion of redundant Second World War-era fleet submarines to enabled to carriage and launch of a seaplane model of the Douglas A-4 Skyhawk attack aircraft, which would have been equipped with hydro-skis for takeoff similar to those of the Sea Dart.
