MORANE-SAULNIER TYPE AN (MoS 31 TO MoS 34) France

   Designed to use a 450 hp Bugatti 16-cylinder water-cooled engine, the Type AN two-seat fighter completed in the summer of 1918 was a large, two-bay equi-span staggered biplane with a monocoque fuselage. Officially tested at Villacoublay on 27 October 1918, the Type AN produced disappointing results and alternatives to the unorthodox Bugatti engine were investigated. The 400 hp Liberty 12 was installed in the Type ANL and the 450 hp Renault 12Kb in the Type ANR, both being tested in 1919. The armament of the AN series aircraft consisted of a forward-firing 7,7-mm Vickers gun and twin 7,7-mm Lewis guns on a flexible mount in the rear cockpit. The final variant of the basic design, the Type ANS, was fitted with a 530 hp Salmson 18Z 18-cylinder water-cooled two-row radial. Development continued through 1919, the Type ANL becoming the MoS 32, the ANR becoming the MoS 33 and the ANS becoming the MoS 34, but, although some promising results were obtained, further development was discontinued. The following data relate to the Bugatti-engined prototype.
