Airco DH.11 Oxford

The Airco DH.11 Oxford was a British twin-engined biplane bomber, designed by Geoffrey de Havilland for the Aircraft Manufacturing Company as a day bomber to replace the DH.10 Amiens. It was designed, as the specification required, around the ABC Dragonfly radial engine, which promised excellent performance and had been ordered in large numbers to power most of the new types on order for the Royal Air Force. The DH.11 was a three-bay wooden biplane with a clean, deep fuselage that filled the whole wing gap and gave the gunners a good field of fire. The first prototype flew in January 1919 with two 320 hp Dragonfly engines, but the engine proved unsuccessful. Two further prototypes were cancelled in 1919, no aircraft was bought to replace the DH.10, and the design was abandoned after the single prototype was built.
