Martin MO

The Martin MO was an American observation monoplane built by the Glenn L. Martin Company of Cleveland, Ohio for the United States Navy. In the early 1920s the Navy became interested in the thick airfoil and cantilever wing of a Dutch Fokker observation aircraft, and its Bureau of Aeronautics designed a three-seat monoplane around a similar wing. Production of the MO-1 was contracted to Martin with an order for 36 aircraft. It was a shoulder-wing cantilever monoplane with a slab-sided fuselage, fixed tailwheel landing gear, an all-metal structure with fabric covering and a Curtiss D-12 engine, and in 1924 one aircraft was fitted with floats for evaluation.
