Role: Fighter
Manufacturer: Focke-Wulf
Status: Unfinished project

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. The design began as Focke-Wulf Project V which had a central fuselage and two booms carrying the rear control surfaces. This was at about the same time that the de Havilland Vampire was under development. When the Vampire was first seen in the Focke-Wulf Projects Office in 1945, there was considerable amazement at the marked similarity of the two aircraft. However, this similarity was due to nothing more than two independent development teams coming up with the same solution to a common problem. Project V had the air inlets still positioned on either side of the nose, just below the cockpit.

The estimated horizontal speed was not satisfactory and, in the next development, Project VII the jet intakes were situated in the wing roots, like the Vampire. (It is possible that two forms of intake were considered, one triangular and the other rectangular.) Further improvements over Project V 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).
