A Legacy of Defense
Spirit AeroSystems’ headquarters in Wichita, Kansas, sits at the epicenter of America’s WWII-era defense aircraft production. It was on this site that some of the most important aircraft in U.S. Defense and Boeing history were built, including the B-29 Superfortress, the B-47 Stratojet and the B-52 Stratofortress. At Spirit AeroSystems, military aircraft manufacturing is truly part of the very ground we build on.
Global Defense Connections
Spirit’s defense legacy credentials stretch from the 1930s to the 1990s and from the American Midwest to the Scottish Ayrshire countryside. Spirit’s Prestwick, Scotland location was where Scottish Aviation Ltd. was founded in 1935. This facility was an essential producer of aircraft during WWII. In the latter half of the 20th century, Spirit’s Oklahoma locations were Rockwell International sites, producing components for the International Space Station, the Joint Strike Fighter and the Nimrod MRA4.
B-29 Superfortress Assembly in Wichita, Kansas
The first B-29s rolled off the Boeing-Wichita lines in September 1943. By the end of WWII, Boeing-Wichita was producing 4.2 Superfortresses per working day for an average of 100 per month, and had reduced the man hours needed to produce each aircraft from 157,000 to less than 20,000. Of the 3,888 B-29s built, 1,644 were Wichita-made.
