Training and Testing in the Northwest

The Navy’s mission in the Northwest directly supports the national security mission.

Sustaining our mission, including executing today's operations and developing the capabilities and capacity for tomorrow's force depends on our responsible stewardship of the land, waterways and resources with which we are entrusted.

In addition to keeping the sea lanes open to travel and trade, the Navy needs to be ready to respond to a wide range of situations such as large-scale conflict, homeland defense, anti-piracy operations, and humanitarian assistance and disaster relief. This level of readiness and capability is achieved through comprehensive, realistic training and testing. Proper training and testing enables Sailors to successfully accomplish the national defense mission, save lives, and preserve our way of life.

Training and testing ranges in the Northwest are vital to preparing Navy personnel for deployment and homeland defense by providing these realistic training and testing environments.


Balancing Training & Testing Needs with Environmental Stewardship


Environmental Planning & NEPA Compliance

The Navy evaluates the potential environmental effects from proposed military readiness training and testing activities in the Northwest Region. Visit the link above to view Navy Environmental Assessments (EAs) and Environmental Impact Statements (EISs) for proposed actions in the Navy’s Northwest Region, which includes Washington, Alaska, Idaho, Iowa, Minnesota, Montana, Nebraska, North Dakota, Oregon, South Dakota and Wyoming.  These documents are prepared in accordance with the National Environmental Policy Act (NEPA), which requires all federal agencies to consider potential environmental consequences from a wide array of proposed major Federal actions before decisions are made and actions are taken.
