Silverdale is the primary community adjacent to Naval Base Kitsap Bangor — the West Coast homeport of the Ohio-class ballistic missile submarine fleet, each boat carrying up to 20 Trident II D5 missiles with multiple nuclear warheads. Bangor houses the largest single concentration of deployed nuclear weapons in the United States. The Cascadia Subduction Zone creates a major earthquake and tsunami threat for the entire Puget Sound region. As US-Iran tensions escalate and broader nuclear posture becomes relevant, understanding the communities surrounding America's sea-based nuclear deterrent becomes essential for preparedness planning.
