The Boeing C-40 Clipper is a military version of the Boeing 737-700C airline transport. It is used by both the United States Navy and the United States Air Force.

The Air Force awarded the medium lift contract in August 2000. The 89th Airlift Wing acquired its first C-40B aircraft in December 2002. Both units are based at Andrews Air Force Base, Maryland. The 15th Airlift Wing, Hickam AFB, Hawaii, acquired its C-40B for U.S. Pacific Command in February 2003. The 86th Airlift Wing, Ramstein AB, Germany, acquired it's C-40B for U.S. Air Forces in Europe in December 2004.
The cabin area is equipped with a crew rest area, distinguished visitor compartment with sleep accommodations, two galleys and business class seating with worktables.
The C-40B is designed to be an "office in the sky" for senior military and government leaders. Communications are paramount aboard the C-40B which provides broadband data/video transmit and receive capability as well as clear and secure voice and data communication. It gives combatant commanders the ability to conduct business anywhere around the world using on-board Internet and local area network connections, improved telephones, satellites, television monitors, and facsimile and copy machines. The C-40B also has a computer-based passenger data system.
