C-40B Special-Mission Aircraft

Overview

C-40B above the runway The C-40B is a special-mission aircraft that provides airlift with an office-in-the- sky environment for U.S. combatant commanders and other senior government officials. Built for the U.S. Air Force, the 737-700 aircraft is equipped with equipment and capabilities that support a rapid response for global missions. C-40Bs are equipped with the Connexion by Boeing system, providing secure in-flight broadband connectivity -- data/video transmit and receive capability -- to enhance communications, productivity and security.

Capabilities and Characteristics

The C-40B is based on the Boeing Business Jet, and includes the following enhancements:

  • Updated avionics
  • 777-type flight deck with common-display system (includes liquid-crystal displays)
  • CFM56-7 engines (built by CFM International)

  • 27,300 pounds of thrust
  • Higher cruise speed (0.78 to 0.82 Mach)
  • Greater range (3,000 nautical miles)
  • Noise-reduction improvements (below Stage 3 levels)
  • Greater fuel-efficiency and lower maintenance costs

Milestones

Boeing was contracted by the Air Force to build four C-40B aircraft.

  • First flight: June 2002
  • Delivery of first aircraft: December 2002
  • Delivery of second aircraft: January 2003
  • Delivery of third aircraft: 2004
  • Delivery of fourth aircraft: expected June 2005

Maintenance

Because the C-40B is based on the commercially successful 737, it shares a readily available supply of parts, the 737 network of comprehensive field services, and the 737 spares-distribution network. Consequently the C-40B will offer reduced maintenance costs. The U.S. Air Force will operate and maintain the aircraft.
