Naval Undersea Museum explores undersea technology and naval history in Keyport. Exhibits connect submarines, diving and ocean-related engineering with the people who developed and used these systems.
Check current opening days and holiday closures before arrival. Admission and parking are free, and the museum’s public location does not require access to the neighboring naval base. The photograph shows the museum building and surrounding grounds rather than a particular current exhibit or permission to enter operational military facilities.
Visitor details reviewed October 18, 2026. Check official visitor information for current access, admission, and operating arrangements. View on OpenStreetMap.
