Morane-Saulnier P (MoS 21)


During the summer of 1916, Morane-Saulnier produced two different single-seat fighter versions of the Type P reconnaissance two-seat parasol monoplane. Both were powered by the 110 hp Le Rhóne 9J nine-cylinder rotary, but whereas the first single-seater was a simple conversion retaining the forward cockpit of the two-seater and carrying a single synchronised 7,7-mm Vickers gun, the second version featured a lower-mounted wing, an armament of twin synchronised 7,7-mm guns and an aft-positioned cockpit. Allegedly the first Allied twin-gun fighter, the latter was 183 lb (83 kg) heavier than the former in loaded condition and 56 mph (9 km/h) slower at sea level, recorded performance figures proving inferior to those of the two-seat Type P. Two prototypes of the initial version and at least one prototype of the two-gun version were evaluated by the Aviation Militaire, but neither was adopted for series production and the single-seat Type P was officially abandoned in December 1916.
