Seattle played a critical role in the allied war effort during World War II. Situated far from the battlefront, the war nevertheless served as a transformative force, turning urban and rural landscapes into sites of war production. Leaders in government and business sought to use the war as an opportunity to remake the city and the region. The efforts of planners and the demands of the military coalesced to bring war industries to the Pacific Northwest and Seattle. This essay examines the development of Seattle’s major war industries, particularly aircraft manufacture and shipbuilding, and demonstrates how the war reshaped Seattle by generating new networks of capital and commodities and by creating a lasting military-industrial complex in the city.
