About this Unit
US Naval Facility Brawdy, Wales, was a key American military installation operated by the United States Navy from 1974 to 1995. Situated on the southwestern coast of Wales, the facility played a crucial role in undersea surveillance as part of the Sound Surveillance System (SOSUS), designed to track Soviet submarine activity during the Cold War. Staffed by both US Navy personnel and civilian contractors, NAVFAC Brawdy supported NATO maritime defense operations in the North Atlantic. The facility was closed following the end of the Cold War, with its mission and function transferred or decommissioned as part of broader post-Cold War military reductions.
