Ju EF 128  3 view     This Junkers design was submitted for the Emergency Fighter Competition in Febuary 1945. The fighter had air intakes at the fuselage sides to divert the boundry-layer air flow to a vent outlet aft of the cockpit fairing. The wings were of wooden construction, swept back 45 degrees and had two small vertical fins and rudders on the wing trailing edges. 540 liters (143 gallons) of fuel were contained in the wings, and a further 1025 liters (271 gallons) were contained in a fuselage tank located just behind the cockpit. A pressurized cockpit was provided with an ejector seat and armor (protection from 12.7 mm rounds from the front, and 20 mm rounds from the rear). Power was supplied by a Heinkel-Hirth HeS 011 jet engine, and two MK 108 30 mm cannon were installed in the sides of the fuselage nose with 100 rounds each, with a provision for two more. Good results were obtained with a completed wind tunnel model, and a mock-up fuselage with an HeS 011 jet was built for tests in which it was to be mounted above a Ju 88. An additional night fighter/all-weather fighter with a lengthened fuselage and room for a second crew member was also in the design phase, but neither project was completed due to the war's end.
