Design and development
First flown in 1931 the Loening SL was lightweight flying-boat designed to be folded up and stored on a submarine within an 8-foot space. It was a single-seat, mid-wing monoplane powered by a 110 hp (82 kW) Warner Scarab radial engine mounted above the wing driving a pusher propeller. Originally designated the XSL-1 by the Navy it was re-designated XSL-2 in 1932 when it was re-engined with a 160 hp (119 kW) Menasco B-6 engine. Only the prototype was built and it was not ordered into production.
