Naval Facility Point Sur, Cold War naval surveillance facility in Big Sur, California.
Naval Facility Point Sur was a military installation on California's coast south of Point Sur, consisting of administration buildings, operations facilities, and support structures spread across the coastal terrain. The site functioned as part of a broader network designed to monitor underwater activity in the Pacific.
Built in 1958, the facility used SOSUS technology to detect Soviet submarines during the Cold War as part of underwater surveillance operations. It closed in 1984 after computerized systems made the facility's onsite operations less necessary.
The facility maintained a cover story of conducting oceanographic research while operating as part of a classified network of submarine detection stations.
The site is located in a remote section of California's coast, and access may be limited due to its protected location. Check local conditions and any restrictions before planning a visit to this area.
In 1968 the facility helped locate Soviet submarine K-129, leading to a secret salvage operation that remained classified for decades. This achievement was one of the most significant intelligence successes of the Cold War era.
