Development

The D prototype was offered to the US Army Air Service at the end of 1918. It was a two-bay biplane, constructed of all wood and covered with fabric. It was powered by a 300hp Hispano-Suiza engine. The pilot of the first flight test, Clarence B. Coombs, gave it a positive evaluation: "This aircraft performs better than the Sopwith Camel and Snipe, the Thomas-Morse, the Nieuport and Morane Parasol, the Spad and S.V.A."^[1] The military ordered 50 production aircraft, but put the production order up for bidding. Curtiss Aircraft entered the lowest bid and built the fighter, modifying it slightly with a wider wingspan and redesigned ailerons.^[2] The first Curtiss Orenco D flew on 26 August 1921.^[1]
