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.
