US Naval Facility Pacific Beach, WA

The US Naval Facility Pacific Beach, located on the Washington coast, was established in 1951 as part of the Sound Surveillance System (SOSUS) during the Cold War. Its primary mission was to conduct undersea surveillance, using advanced hydrophone arrays to detect and track Soviet submarines operating in the Pacific Ocean. The facility played a crucial role in anti-submarine warfare efforts and contributed significantly to the security of US naval operations in the region. Decommissioned in 1987, the site was later repurposed for other Navy uses, including as a recreation area for military personnel.
