It has been widely reported that the Germans unanimously decided to surrender to the Western Allies. This is not the case. Some of the scientists were more impressed by the Soviet system than they were by American capitalism, and Helmut Gröttrup was the most conspicuous of these. Gröttrup was an electronics engineer who no longer wished to 'understudy' Von Braun as he had done in the development of the V-2 rocket. Gröttrup decided to approach the Soviets and was offered a senior position in Russian rocket development. Between 9 September 1945 and 22 October 1946 Gröttrup with his loyal team of researchers worked for the USSR in the Soviet Occupied Zone of Germany (later to become the German Democratic Republic). His director of research was Sergei Korolev, Russia's leading rocket scientist. In the autumn of 1946, the entire team was moved to Russia. Gröttrup had cooperated with Russia in bringing 20 of the V-2 rockets to the newly established rocket research institute at Kapustin Yar, between Volgograd and the deserts of Astrakhan. The base is known today as Znamensk and it had opened on 13 May 1946 specifically to offer facilities to German experts. In charge was General Vasily Voznyuk and on 18 October 1947 they launched the first of the V-2 rockets brought in from Germany.
Gröttrup worked under Korolev to develop the Russian R-1 project; these were in reality V-2 rockets built using Russian manufacturing and materials with the German designs. The People's Commissar of Armaments, Dmitry Ustinov, requested that Gröttrup and his team of technicians design new missile systems, culminating in the projected R-14 rocket which was similar to the design of long-range missiles that Von Braun was developing during the war. The site at Znamensk developed into a top-secret cosmodrome and the small town itself was expanded to provide a pleasurable and civilized lifestyle for the families of the research teams working on the rockets. It was no longer included on Russian maps, and there were strict rules against disclosure of what was going on.
The value of the German expertise to the Russians proved to be limited and, in due course, the authorities allowed the research workers to return to their homes in Germany. The design of rocket motors in Russia by Aleksei Mikhailovich Isaev was already superior to the German concepts used in the V-2 rockets, and their lightweight copper motors gave rise to the first intercontinental ballistic missile, the R-7. It was this design advantage that gave the Russians technical superiority in rocketry and led to their launching the world's first satellite Sputnik 1, and subsequently to the launch of Yuri Gagarin as the first man into space.
The same technology gave the Russians the capacity to launch the first lunar probe, and later the spacecraft sent out towards the planets. Indeed, this design of rocket is still in use today. Once it was recognized that there was little point in keeping the German rocket specialists in Russia, on 22 November 1955 Gröttrup was given leave to return to his native Germany. In cooperation with Jürgen Dethloff he went on to design and patent the chip card which was to become so important in modern banking systems, and so his post-war genius is with us today.
