NAVFAC Grand Turk

NAVFAC Grand Turk was a United States Navy Sound Surveillance System (SOSUS) facility established on Grand Turk Island in the Turks and Caicos Islands during the early years of the Cold War. Commissioned in 1954, its primary mission was to detect and track Soviet submarines in the Atlantic Ocean using underwater listening technology. The facility played a significant role in anti-submarine warfare and intelligence gathering throughout the Cold War era. NAVFAC Grand Turk was decommissioned in 1980 as advances in technology and changing strategic needs led to the consolidation of SOSUS operations.
