Types of C-40 Aircraft
The U.S. Navy uses a version of the 737-700 known as the C-40A. This modified version of the aircraft is used primarily for logistical support. Capable of housing three cargo pallets and 70 passengers aboard the flight deck, it also is fitted with a number of unique features specifically used by the Navy. It uses the Reduced Vehicle Separation Minimum, a technology that allows for closer air support than civilian models. The C-40A also has GPS, collision avoidance systems, warning systems and tactical navigation abilities.
The U.S. Air Force uses the C-40B as its primary sky office for senior commanders and various government leaders. It is capable of secure communications and data management to anywhere in the world. The C-40B is fitted with the Internet, television, fax machines and copiers.
Designed to replace its C-22 fleet, the C-40C is used by the Air National Guard primarily as a transport vehicle. Capable of carrying up to 121 passengers, the aircraft is essentially a personnel mobilizer.
Judging from the length of time the military uses its vehicles, the Clipper will most likely be part of the Navy, Air Force and Air National Guard's respective fleets for many years.
