Spirit’s experience and capabilities in designing and building fuselage structures and systems are vast. These are things that we have been doing for decades on some of the most extensive programs for some of the largest, most sophisticated airplanes ever built. In the process, we have simultaneously managed multiple programs with multiple production rates, delivering world-class quality on time and on budget. Spirit offers state-of-the-art design proficiency and production processes that have proven themselves time and again on major integrated systems programs.
