Delivering for Defense

Spirit AeroSystems’ experience, design-build leadership and cost efficiencies appeal to defense prime contractors working to produce innovative military aircraft. As a reliable and trusted partner, Spirit helps reduce the risk in new development programs while delivering superior performance and reliability for warfighters.

Program Innovation

From commercial derivatives to redesigned platforms and new manufacturing technologies, Spirit is leading the way. Spirit AeroSystems designs, engineers and manufactures structural components for military programs, including Boeing’s P-8, C-40 and KC-46 tanker, all of which are commercial aircraft modified for military use. Spirit is also involved in the development of the Sikorsky CH-53K, Bell Helicopter V-280 Valor tiltrotor and the Northrop Grumman B-21.

Aerial Refueling Tanker Aircraft

A military derivative of the Boeing 767, Spirit has manufactured the tanker’s forward fuselage (Section 41), strut and nacelle components, and the fixed leading edge since 2013. Spirit assisted in the design of the next-generation tanker, which will replace the aging KC-135 Stratotanker fleet.
