The Dornier Do H Falke was a German single-seat fighter designed by Claudius Dornier and built by Dornier Flugzeugwerke. Although an advanced design for its time, being evaluated by the United States Navy as the Wright WP-1, it did not go into production.[1]

Development[edit | edit source]

The company started to design a prototype fighter in the early 1920s based on earlier wartime designs like the Zeppelin-Lindau D.I. It was an all-metal high-wing cantilever monoplane, with the wing above the fuselage on four small struts. It had a conventional cantilever tail unit and a fixed tailskid landing gear. The pilot had an open cockpit just behind the trailing edge of the wing. The aircraft was powered by a Hispano-Suiza piston engine located in the nose. Two aircraft were built by the Swiss subsidiary of Dornier and three by S.D.C.M.P. in Italy,[1] to avoid restrictions on military aircraft production in Germany.[2] It first flew on 1 November 1922, but failed to go into production. One of the Falkes was converted to a floatplane in 1923, powered by a 261 kW (350 hp) BMW IVa V-12 engine, as the Dornier Seefalke.

One Seefalke was shipped to the United States of America by the Wright Aeronautical Company who fitted it with a licence-built Wright-Hisso H-3 engine. It was evaluated by the United States Navy with the designation Wright WP-1.[2] It performed well, but the Navy considered the monoplane fighter too advanced for its needs.[1]
