During 1944, the Miniaturjäger programme for the simplest, cheapest fighter possible was launched by the 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).

[2] Junker's design, the EF 126, was of similar layout to the V-1, with the single Argus 109-044, rated at 4.9 kilonewtons (1,100 lbf), mounted above the aft fuselage and fin.

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.
