Naval Facility San Nicolas Island (NAVFAC SNI), located on San Nicolas Island off the coast of California, was established in 1958 as part of the U.S. Navy’s Sound Surveillance System (SOSUS) network. Its primary mission was to detect and track Soviet submarines during the Cold War using undersea listening technology. The facility operated as a key node in the broader anti-submarine warfare (ASW) efforts, contributing valuable intelligence to the defense of the United States. NAVFAC SNI was decommissioned in 1987 as advances in technology and shifting military priorities led to changes in undersea surveillance operations.
