About this Unit
The Naval Supply Depot - Seattle was established during World War II to serve as a vital logistics and supply hub for the United States Navy in the Pacific Northwest. Activated in 1944, the depot rapidly expanded its operations to support wartime demands, handling a wide range of materials including food, fuel, and equipment destined for Pacific Theater operations. After the war, the facility continued to play a significant role in supporting naval activities during the Cold War era. The depot’s operations were eventually consolidated and phased out as military logistics modernized and regional needs shifted.
