The Boeing Company manufactures the aft fuselage section for the U.S. Air Force's 100th F-22 Raptor air dominance fighter at the company's Developmental Center in Seattle. Boeing manufacturing engineers streamlined production in late 2003 when they replaced the facility's massive stationary assembly jigs with much smaller, more flexible tooling on wheels. For this and other industrial design breakthroughs, Boeing's F-22 assembly center has become a model of manufacturing excellence.
