The design of the Ju EF 126 was developed into the Junkers EF 127, a rocket-powered version.
During 1944, the German: Miniaturjäger programme for the simplest, cheapest fighter possible was launched by the German: [[Reichsluftfahrtministerium]] (RLM), the German Ministry of Aviation. In order to minimise cost and complexity, it was to be powered by a pulse jet, as used by the V-1 flying bomb and its manned version, the Fieseler Fi 103R (Reichenberg). Designs were produced by Heinkel, with a pulse jet powered version of their Heinkel He 162, Blohm & Voss (the P213) and Junkers.
Junker's design, the EF 126, was of similar layout to the V-1, with the single Argus 109-044, rated at 1100lbf, mounted above the aft fuselage and fin. The fuselage was of metal construction while the wings were wooden. A retractable nosewheel undercarriage was to be fitted. As the pulse-jet's power would reduce at altitude, the aircraft was intended for low-altitude use, and had a secondary ground attack role. Armament consisted of two 20 mm MG 151/20 cannon while up to 400kg (900lb) of bombs could be carried under the wings.
