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 Navy C-40A variant is named "Clipper", whereas the USAF C-40B/C variants are officially unnamed.

Design and development[edit]

C-40A[edit]

The C-40A Clipper provides critical logistics support to the United States Navy. Its flight deck features a flight management computer system with an integrated GPS, and is compatible with future GATM/FANS operating environment (RNP-1).[citation needed] It is outfitted with the Traffic Alert and Collision Avoidance System II, and is RVSM-capable. It also has an enhanced ground proximity warning system, predictive wind shear, head-up display and TACAN/UHF/IFF[clarification needed] functions.[citation needed]

The U.S. Navy Reserve was the first customer for the newest member of the Boeing 737-700C Next-Generation family.[1][2] The Clipper was ordered by the U.S. Navy to replace its fleet of aging C-9B Skytrain IIs. The C-40A is the first new logistics aircraft in 17 years to join the U.S. Navy Reserve. The Navy Reserve provides all of the Navy's medium and heavy airlift capabilities.[citation needed]

The Clipper meets or exceeds international noise and environmental requirements, which the fleet of Naval Reserve C-9s did not. It is also more fuel-efficient and offers increased range and payload capabilities. The Clipper is certified to operate in an all-passenger (121 passengers), all-cargo or combination ("combi") configuration that can accommodate up to three cargo pallets and 70 passengers on the main deck.[3]

The Navy purchased the airplanes using standard commercial practices, ordering six of the 737-700C models[when?]. The first two of four aircraft were delivered on 21 April 2001 to Fleet Logistics Support Squadron Five Nine (VR-59) at the Naval Air Station/Joint Reserve Base Fort Worth, Texas, with two more aircraft following before the end of the year. The fifth and sixth aircraft were delivered in August 2002 to VR-58 at the Naval Air Station Jacksonville, Florida. Further aircraft have been delivered to VR-57 at the Naval Air Station North Island, California. The C-40A provides superior fuel efficiency, range and payload.[4]

C-40B[edit]

The United States Air Force selected the C-40B, a military version of the 737-700 Boeing Business Jet, to replace the aging fleet of C-137 aircraft for U.S. combatant commanders. 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 its C-40B for U.S. Air Forces in Europe in December 2004.[5]

The cabin area is equipped with a crew rest area, distinguished visitor compartment with sleep accommodations, two galleys and business class seating with worktables.[5]

The C-40B is designed to be an "office in the sky" for senior military and government leaders. The aircraft features two-way broadband data communications, including secure voice and data communication; elements include internet and network access, telephones, satellites, facsimile and copy machines. The C-40B also has a computer-based passenger data system.[5]

C-40C[edit]

The C-40C is not equipped with the advanced communications capability of the C-40B. Unique to the C-40C is the capability to change its configuration to accommodate from 42 to 111 passengers.[5] The C-40C replaced three C-22s (a militarized Boeing 727) operated by the Air National Guard and National Guard Bureau to airlift personnel. The C-40C was the first military aircraft to be acquired in this manner. The 201st Airlift Squadron, District of Columbia Air National Guard acquired two C-40C aircraft in October 2002. The Air Force Reserve 932d Airlift Wing, Scott AFB, Illinois acquired three C-40C aircraft in 2007.[5]
