The Junkers EF 009 Hubjäger (German: "lift-fighter") was an unrealized design for an unorthodox jet fighter dating from the late 1930s.
Design & developmentEdit
The EF 009 was designed as a point defense interceptor, to be positioned around vital locations then launched when they were in trouble. The plane was to be powered by ten jet engines clustered around its nose and was expected to sustain flight for six minutes. It would then land unpowered on a central skid mounted on the front of the plane. To cope with g-forces during takeoff, the pilot would lie in a prone position. Takeoff would most likely be from a specially-designed cart, or vertically like a rocket. Armament was to consist of two MG 151/20 20 mm cannons or two MK 108 30 mm cannon. Aircraft design advances made this project obsolete almost before the plans were even complete.
