About this Unit
Naval Security Group Activity (NSGA) Edzell, located in northeast Scotland, was established in 1960 as a U.S. Navy signals intelligence (SIGINT) and communications site during the Cold War. Its mission focused on intercepting and analyzing Soviet naval and military communications in the North Atlantic, supporting both U.S. and NATO operations. The base housed American military personnel and their families, fostering close ties with the local Scottish community. After decades of service, NSGA Edzell was closed in 1997 as part of broader post-Cold War realignments and advances in global communications technology.
