Field Station Key West FL

Field Station Key West, located in Key West, Florida, was a United States Army Security Agency (ASA) signals intelligence (SIGINT) facility established during the early years of the Cold War. Activated in the late 1940s, the station played a crucial role in intercepting and analyzing communications from Cuba and the Caribbean, especially during periods of heightened tension such as the Cuban Missile Crisis. Operated primarily by the 313th ASA Battalion and later by various military intelligence units, Field Station Key West provided valuable intelligence to national decision-makers. The facility was eventually closed as advances in technology and shifting strategic priorities rendered its mission obsolete, but its legacy remains an important chapter in U.S. military intelligence history.
