US Army Field Station Berlin

The US Army Field Station Berlin was established in the early 1950s as a critical signals intelligence (SIGINT) facility during the Cold War. Manned primarily by personnel from the Army Security Agency, the unit operated atop Teufelsberg, a man-made hill in West Berlin, using its distinctive radomes to intercept and analyze Warsaw Pact communications. Throughout its existence, the Field Station played a pivotal role in gathering intelligence on Soviet and East German military activities, contributing to NATO’s situational awareness. The unit remained active until German reunification, with operations ceasing in 1992 as the Cold War came to an end.
