On 18 July the Soviet administration created the Institute Rabe to develop Soviet rocket technology on the basis of the substantially more sophisticated V-2 rockets. In May 1946 the Institute was subsumed into the new Institute Nordhausen, under an expanded programme of research across the Soviet occupation zone, including a new Institute Berlin. On 22 October 1946, under Operation Osoaviakhim, 10–15,000 German scientists, engineers and their families were deported to the Soviet Union, including around 300 from Nordhausen. Transplanted along with their equipment, many of the scientists and their families lived there until the early 1950s.
