About this Unit
NAVFAC Nantucket, officially known as Naval Facility Nantucket, was a United States Navy installation located on Nantucket Island, Massachusetts. Commissioned in 1955, it was part of the Sound Surveillance System (SOSUS), a network of underwater listening posts designed during the Cold War to detect and track Soviet submarines. The facility operated for nearly three decades, contributing significantly to undersea surveillance and anti-submarine warfare efforts in the Atlantic. NAVFAC Nantucket was decommissioned in 1976, following advancements in surveillance technology and changing strategic needs.
