The OKB-1 EF 140 was a prototype aircraft developed in the Soviet Union by captured German engineers from the Junkers factory, originally conceived as a bomber, but later considered as a reconnaissance machine. The aircraft was a follow-on from the Junkers Ju 287 bomber prototype, but while it used the same basic layout and engineering concepts, it was an entirely new design by Brunolf Baade .
Only one EF 140 was actually built, and began flight tests on March 15 1949, using Rolls-Royce Nene engines as the intended Mikulin units were not yet ready. The project was cancelled before the second prototype was complete.
