The Sud-Est SE.200 Amphitrite (named after Amphitrite) was a flying boat airliner built in France in the late 1930s,[1] originally developed as the Lioré et Olivier LeO H-49 before the nationalisation of the French aircraft industry. It was a large, six-engine design with a high-set cantilever monoplane wing, and twin tails. It was developed in response to a French air ministry specification of 1936 for a transatlantic airliner for Air France with a range of 6,000 km (3,700 mi) and a capacity for 20 passengers and 500 kg of cargo.[2] Designs were submitted by Latécoère, Lioré et Olivier and by Potez-CAMS as the Laté 631, LeO H.49 and the Potez-CAMS 161 respectively, and examples of all designs were approved for construction. A large mock-up, resting on simulated water, was displayed at the 1938 Salon de l'Aéronautique.[3]

Four SE.200s were under construction at Marignane at the outbreak of the Second World War, and work on them continued after the fall of France, along with a fifth aircraft now started. The first aircraft, christened Rochambeau flew on 11 December 1942.[4] Following testing, it was seized by the German occupation and taken to the Bodensee, where it was destroyed in an air raid by RAF Mosquitos on 17 April 1944.[5] A USAAF raid on Marignane on 16 September destroyed the second SE.200 and badly damaged the other airframes.[5]

Enough work on the third SE.200 had been carried out to make salvage worthwhile after the war. This aircraft eventually flew on 2 April 1946 but was damaged in a hard landing in October 1949 and was not repaired.[6] Plans existed to also complete the fourth airframe, but this did not happen and it and the fifth airframe were scrapped. The remains of the first SE.200 were raised by Dornier in 1966.[6]
