About the EIS/OEIS Study Area

Northwest Training and Testing EIS/OEIS Study Area

USS Cleveland (LPD 7) transits through Puget Sound during Seattle Seafair The land, air, and sea areas of the Pacific Northwest are important to members of the Navy and their families who call the Pacific Northwest their home. The Navy and the U.S. Coast Guard conduct military readiness activities in designated areas of the northeastern Pacific Ocean, including ocean areas offshore of Washington, Oregon, and Northern California, and in the Western Behm Canal in southeastern Alaska. The Navy also trains and conducts tests in certain areas within the Strait of Juan de Fuca and Puget Sound, and at Navy pierside locations.

Puget Sound Naval Shipyard and Downtown Bremerton waterfrontAreas in the Pacific Northwest have historically been used by the Navy for training and testing activities, with some activities dating back to 1914. Navy training and testing areas within the Study Area have provided a safe and realistic environment for training Sailors and testing systems. The proximity of these areas to naval homeports allows for:

  • Greater efficiencies during training and testing
  • Shorter transit times
  • Reduced fuel use, cost, and emissions
  • Reduced wear and tear on vessels, submarines, and aircraft
  • Maximizing Sailors’ training time and reducing time away from their families
