The OKB-1 '140', (sometimes known as '001') was a jet bomber produced in the USSR from 1947.
Development
The '140' was a reconnaissance/bomber aircraft, derived from the OKB-1 EF 131 with Soviet turbojet engines. The initial version, a tactical jet bomber with a secondary reconnaissance role, was initiated as the EF-140 by Dr. Brunolf Baade, at OKB-1, in 1947. The six Jumo 004 engines of the EF-131 were replaced by two Mikulin AM-TKRD-01 axial flow turbojets, rated at 32.372 kN (7,280 lb) thrust, in large nacelles attached to the underside of the wing at the same position.
