In March 1943 Focke-Wulf in Bremen initiated a series of design studies for single-seat, jet powered fighters. Entwurf 6, also known as Projekt VI, was approved for mock-up construction in Febuary 1944. The designation was later changed to Projekt VII and was given the code name "Flitzer" (Madcap). The mid-fuselage mounted wings had moderate sweepback (32 degrees), twin booms and a high mounted tailplane. The single He S 011A tubojet was to be supplemented with a Walter HWK 509 A-2 bi-fuel rocket mounted below the jet, although this arrangement was later revised, eliminating the rocket engine. Projected armament consisted of two MK 103 30mm cannon or two MK 108 30mm cannon in the lower nose and two MG 151/20 20mm cannon in the wings. The "Flitzer" was well advanced in development, a full-size mock-up (photos below) and some prototype sub-assemblies being completed. The project was eventually abandoned because, although using only a single turbojet, its performance was no better than the Me 262 which was entering service.
