The Junkers EF 126 was an experimental fighter proposed by the German Miniaturjägerprogramm of 1944-1945, for a cheap and simple fighter powered by a pulse jet engine. No examples were built during the war, but the Soviet Union completed a single unpowered prototype, which crashed during testing.The design of the Ju EF 126 was developed into the Junkers EF 127, a rocket-powered version.
