​Spirit's developmental engineering capabilities are demonstrated in the unusual level of delegated design authority granted by Spirit customers. The Boeing 777 flies with an all-new propulsion system, designed completely by Spirit engineers. This talent translates well to defense platforms where, rather than simply tweak existing designs, the Spirit team builds innovation into the system from the start.

​One of the ways Spirit AeroSystems is unique among tier-one suppliers is its breadth and depth of manufacturing work, providing complete program support for all customers.

​ High-quality engineering and repair solutions start here. Spirit AeroSystems' Global Maintenance, Repair and Overhaul (MRO) Solutions support a wide range of commercial aircraft-both composite and metallic structures-including Airbus, Boeing, GE, Rolls-Royce and more. Spirit also specializes in on-wing repair services and goes beyond MRO to deliver expert engineering services and on-location support for existing aircraft.

​With more than over a century designing and building aircraft, Spirit AeroSystems is leading the way in applying commercial best practices to the defense industry. From yesterday's successes in commercial derivatives to tomorrow's all-new, next-generation designs, Spirit's defense diversification is bringing commercial efficiencies and innovations to the military market, helping to modernize military aircraft more quickly and cost-effectively while maintaining superior quality.

​Built to Win. Spirit AeroSystems is home to some of the world's leading aerostructures engineers and manufacturing minds, with a legacy of aerostructure work stretching back to the world's first aircraft production run, of Wright Brothers aircraft, in 1909 and defense work in World War I.

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.

​ High-volume, high-quality parts start at Spirit AeroSystems. A growing demand for parts production, coupled with Spirit's long-standing machining capabilities and some of the most experienced aerospace workers in the world, make the company's fabrication expansion a clear win for customers and supply-chain partners.

Spirit AeroSystems is applying the best of commercial aerospace manufacturing technology to help modernize the defense industry, leveraging decades of aero structures experience to provide added scalability, efficiency, and affordability. At Spirit AeroSystems, we're proud to help usher in a new generation of military innovation.​

​Spirit AeroSystems' maintenance, repair and overhaul capabilities include solutions for a wide range of commercial aircraft for both composite and metal structures. Spirit's certified repair station services most Boeing commercial platforms in addition to Airbus, GE and Rolls-Royce.

​Spirit AeroSystems' chemical-processing capabilities accommodate a comprehensive range of hard and soft metals with one of the largest automated lines in the industry. Capable of processing parts up to 48 feet in length, Spirit can manufacture a wide range of finished products - from machined fittings to large fuselage skin panels.

Spirit's defense legacy credentials stretch from the 1910s 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.
