In the 1950s, the US Navy considered the internal arrangements of a submarine aircraft carrier that could carry three of these aircraft. Stored in pressure chambers that would not protrude from the hull, they would be raised by a portside elevator just aft the sail and set to take off on their own on a smooth sea but catapulted aft in a higher sea. The program only reached the « writing on a napkin » stage, for two problems were not addressed: the hole for the elevator would have seriously weakened the hull and the load of a laden elevator would also be difficult to transmit to the hull structure.^[6]
