The planes are modified 737-700 aircraft and are used for movement of personnel and cargo. They are replacing the U.S. Navy Reserves' C-9B Skytrains, which are based on DC-9s.
"The C-40A offers superior performance and range, 21st-century avionics and quiet, fuel-efficient engines and is increasing the Navy's capability for rapid response," said Andy Reheis, Boeing Global Transport and Executive Systems program manager. "Boeing looks forward to continuing our support of the Navy and meeting the service's airlift needs."
The aircraft ordered will be the 13th and 14th Clippers operated by the Navy under its Unique Fleet Essential Airlift Replacement Aircraft Program.
Boeing said the aircraft will be built in Renton, Wash., and sent to the company's facility in San Antonio for modifications and certification.
