Final extrapolation of the V-2 rocket engine in Russia. Designer at OKB-456 was V A Vitkin. Glushko states 'thus ended the German page' of German engine technology in the USSR (this ignores the fact that the German ED-140 design provided the basis for the entire next generation of Soviet rocket engines). The engine introduced automatic thrust regulation in flight, a feature first advocated by Groettrup's German team for the G-1 engine.
