Léon and Robert Morane and Raymond Saulnier formed Société Anonyme des Aéroplanes Morane-Saulnier 10 October 1911 at Puteaux (Paris region). Vast output ensued of 140 different types, early designs being primarily braced monoplanes, leading to 2-seat Type G (1912), single-seat Type H and Type L (1913) and shoulder-wing Type N (1914). Various parasol monoplanes (notably Type AI, 1917, 1,210 built) and biplanes followed. Type AR parasol-wing trainer (1915) continued post-war as M.S.35 (400+ built), Type P reconnaissance aircraft (565) being similar. From 1920 MS concentrated on radial-engined parasol-wing fighters and trainers, several reaching 3-figure total and M.S.230 trainer (1929) exceeding 1,100 and M.S.315 trainer (1932) 346. M.S.405 fighter (8 August 1935) was low-wing monoplane with retractable landing gear, but outdated structure and only 860 hp, so production M.S.406 was no match for Bf 109E (1,081 delivered by June 1940 Armistice). M.S.470 Vanneau advanced trainer (22 December 1944) led to 500 of 3 versions. Single- and twin-engined light aircraft followed, ending with 165 M.S.760 Paris twin-jet 4-seaters (29 July 1954) and M.S.880 Rallye light 3-seater (10 June 1959). Company take-over by Potez 1963 as Soc. d’Exploitation Etablissements Morane-Saulnier was followed by reorganization May 1965 as subsidiary of Sud-Aviation, losing identity as part of SOCATA.
