British-American scientific intelligence collaboration during the occupation of Germany

Both the Cold War and the arms race began during the Occupation of Germany (1945-55). Acquiring information on the Soviet Union's post-war armaments build-up became the top priority of the intelligence agencies of Britain and the United States and the main sources of this information lay in Germany. That they were fellow-Occupiers of Germany was therefore central to the development of British-American scientific intelligence collaboration during this period. Their intelligence agencies had to collaborate to do their job properly and in partnership they achieved in Germany the first significant penetration of the USSR's military-industrial complex.
