The Noroit was an amphibian flying boat designed for the French Navy, a cantilever gull-wing monoplane with a two-step hull. It had a cantilever horizontal tail surface with three vertical surfaces. It had an enclosed cabin for the seven crew with large cabin in the rear for use in rescue operations. The aircraft had two-engines located one on each wing leading edge. The prototype as a flying boat first flew on 6 January 1949 powered by two 1,200 kW (1,600 hp) Gnome-Rhône 14R radial engines. The second aircraft was fitted with a retractable tailwheel landing gear for amphibious operation which was later retrofitted to the prototype. The next two aircraft first flown in 1949 were designated the Nord 1401 Noroit and were fitted with two 1,300 kW (1,800 hp) Junkers Jumo 213 engines and both were also tested with two Bristol Hercules radial engines. These two aircraft were modified to production standard as the Nord 1402 Noroit and were followed by 21 production aircraft. The last aircraft delivered to the French Navy in 1956.
