The OKB-1 150 was a jet bomber designed and produced in the Soviet Union from 1948. Development At the end of World War II, many German engineers were 'seconded' by the Soviet government to continue their advanced research under direct supervision of the USSR. One of the most significant German teams was OKB-1 (opytno-konstruktorskoye byuro – experimental design bureau) set up in GOZ-1 (Gosudarstvenny opytnyy zavod – state experimental plant) at Dubna near Moscow. OKB-1, with Dr. Brunolf Baade as chief designer, continued work on German-built aircraft such as the EF-131 and '140', which used many components of the two EF-131's, as well as design work on the stillborn EF 132 long-range bomber. By early 1948 Semyon Alekseyev had been appointed supervisor/chief warden/supervisor of OKB-1, with Dr. Brunolf Baade remaining as chief designer. This has caused confusion in the past with '150' being ascribed to Alekseyev and not OKB-1 (OKB-1 was not named after Baade for propaganda reasons). In 1948 OKB-1 started design work on a new jet bomber, designated RB-2 (Reaktiivnyy Bombardirovshchik – jet bomber), to a specification drawn up by ADD (Aviahtsiya Dahl'nevo Deystviya - long range aviation). This design evolved until the use of a new designation seemed prudent and thus '150' was born.

P.S. the author condemns nazism, fascism and another shit.
