Naval Facality Cape Hatteras

Naval Facility Cape Hatteras was a United States Navy Sound Surveillance System (SOSUS) shore terminal located on Cape Hatteras, North Carolina. Commissioned in January 1956, it served as a critical node in the early-warning network designed to detect and track Soviet submarines during the Cold War. The facility processed underwater acoustic data collected by an array of underwater listening devices (hydrophones) positioned offshore. After decades of service contributing to U.S. undersea surveillance, Naval Facility Cape Hatteras was decommissioned in June 1982 as technological advancements rendered some SOSUS stations redundant.
