Field station Berlin

Field Station Berlin was a United States Army intelligence facility located atop Teufelsberg in West Berlin during the Cold War. Established in the 1950s, it played a crucial role in signals intelligence (SIGINT), intercepting and analyzing Warsaw Pact communications. Operated by the U.S. Army Security Agency (ASA), National Security Agency (NSA), and allied forces, the station provided vital intelligence and early warning information. With the end of the Cold War and German reunification, Field Station Berlin ceased operations in 1992, marking the end of its strategic mission.
