This fighter would be powered by a Heinkel HeS 011 turbojet and armed with four MK 108 cannons, reaching a speed of 1000 km/h at an altitude of 7000 m. The production in series was projected to start around mid-1945.


As part of the Emergency Fighter Program (German: Jägernotprogramm), at the beginning of 1945 a programme was launched by the OKL in order to replace the He 162 Spatz,[2] the winner of the earlier Volksjäger "people's fighter" design competition. The new aircraft was intended to have superior performance in order to deal with high altitude threats such as the B-29 Superfortress. To meet this requirement, power was to be a single Heinkel HeS 011 turbojet. The designs of the official winner of the competition, the Junkers EF 128, were submitted in February 1945. The plane designs brought forward by other German aircraft makers were the Messerschmitt P.1110,[3] Heinkel P.1078, Focke-Wulf Ta 183 and Blohm & Voss P 212.[4]

This more advanced fighter attracted more interest than the austere Miniaturjäger among German aircraft manufacturers, but at the time of the Surrender of Nazi Germany in World War II only models had been built.[5] It had swept wings which included wood in their construction. There was a projected variant of a two-seater all-weather/night fighter with a lengthened fuselage.[6]
