U. S. Naval Field Station, Sinop, Turkey

The U.S. Naval Field Station, Sinop, Turkey, was established in 1957 as a critical signals intelligence (SIGINT) facility during the Cold War. Operated primarily by the U.S. Navy and National Security Agency (NSA), its strategic location on the Black Sea allowed for effective monitoring of Soviet military communications and missile activities. The station played a key role in intelligence gathering until diplomatic changes and advancements in technology led to its closure in 1992. Throughout its operation, Sinop significantly contributed to U.S. and NATO intelligence capabilities in the region.
