The Focke-Wulf Project VII Flitzer ("streaker" or "dasher", sometimes incorrectly translated as "madcap") was a jet fighter under development in Germany at the end of World War II.

Development[edit]

The design began as Focke-Wulf Project VI which had a central fuselage and two booms carrying the rear control surfaces having great similarity with the de Havilland Vampire.[2] Project V had the air inlets still positioned on either side of the nose, just below the cockpit.[3]

The estimated horizontal speed was not satisfactory and in the next development, Project VII, the jet intakes were situated in the wing roots. Further improvements over Project VI were a narrower fuselage and a changed pilot's canopy. In order to improve the rate of climb, a Walter HWK 109-509 liquid rocket was built-in. In spite of the fact that a complete mock-up was built and all construction and assembly plans finished, the aircraft was not accepted by the RLM (Reich Air Ministry, or Reichsluftfahrtministerium).[4]
