Spirit AeroSystems

Spirit AeroSystems designs and manufactures large, complex aerostructures for commercial aircraft, defense platforms, business jets and regional aircraft. Its work covers fuselages, wings, engine pylons, nacelles, struts, fairings and other structural components, built using both composite and metallic materials. The company maintains integrated manufacturing and engineering operations spanning aerostructures design, composite and metallic materials manufacturing, and fuselage, propulsion and wing systems.

Operations are organised into three business segments - Fuselage Systems, Propulsion Systems and Wing Systems - across four geographic regions: North America, Europe, Asia and North Africa. Boeing programs supported include the 737, 747-8, 777X, 787, P-8A and KC-46A; Airbus programs include the A220, A320, A350 and A380.

Founded in 2005, Spirit AeroSystems operated as an independent business for two decades, growing through acquisitions and the addition of new production facilities. On December 8th 2025 it became a wholly owned subsidiary of The Boeing Company.
