NAVFAC Ramey AFB, PR

NAVFAC Ramey AFB, Puerto Rico, was a United States Navy facility established in 1957 as part of the Sound Surveillance System (SOSUS) network during the Cold War. Its primary mission was to monitor and track Soviet submarine activity in the Atlantic Ocean using undersea listening technology. Operated by Navy personnel, the facility worked in close coordination with the nearby Ramey Air Force Base, enhancing U.S. anti-submarine warfare capabilities in the Caribbean region. NAVFAC Ramey remained operational until its decommissioning in 1976, after which its functions were consolidated with other SOSUS sites.
