Boeing rolled out the 5000th Next-Generation 737 in July 2014. The airplane is a Boeing C-40A Clipper, a modified 737-700C, that will serve as a transport aircraft for the U.S. Navy. Utilizing the 737 commercial platform takes advantage of the proven efficiencies, manufacturing processes and performance of the existing Next-Generation 737 production system. Boeing's P-8 maritime patrol aircraft, Airborne Early Warning and Control (AEW&C) and the C-40 are among the 737 military derivatives.
