The Junkers EF 009 Hubjäger (German: "lift-fighter") was an unrealized design for an unorthodox jet fighter dating from the late 1930s.

Design & development

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 un-powered on a central skid mounted on the front of the plane. To cope with g-forces during takeoff, the pilot would lay 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.

  The Maximum Takeoff Weight or Maximum Takeoff Mass of an aircraft is the maximum weight at which the pilot of the aircraft is allowed to attempt to take off, due to structural or other limits. The analogous term for rockets is Gross Lift-Off Mass, or GLOW...

The Bachem Ba 349 Natter was a World War II German point-defence rocket powered interceptor, which was to be used in a very similar way to a manned surface-to-air missile. After vertical take-off, which eliminated the need for airfields, the majority of the flight to the Allied bombers was to be...
