Boeing's Everett facility near Seattle stands as the world's largest manufacturing building, occupying 98.3 acres and with a volume of 472 million cubic feet. Key aircraft such as the Boeing 747, 767, 777, and 787 have been assembled here since its establishment in 1967. The main assembly building, revealing Boeing's commitment to innovation and large-scale production, opened its doors on May 1, 1967.
According to the company, “the site mirrors a small city and has more than 30,000 workers on site each day.” Alongside production, the campus features internal amenities like a bank, daycare, and a water treatment plant, with a tunnel system facilitating transportation and utilities.
Boeing repurposes the factory to adapt to shifting industry demands, including the 777X and defense programs. The Everett factory remains critical in Boeing's strategy, contributing to aviation's future as “the largest building in the world has played a pivotal role in aviation history.”
