Port Orchard Washington sits across the inlet from Bremerton and the Puget Sound Naval Shipyard — one of the most significant naval industrial facilities in the US, responsible for maintaining nuclear-powered aircraft carriers and submarines. Kitsap County hosts more nuclear warheads than any other location in the western hemisphere through Naval Base Kitsap-Bangor. The community sits on Kitsap Peninsula and is vulnerable to Cascadia Subduction Zone earthquakes and the associated tsunamis that would affect Puget Sound.
