These were lengthening of C-141As into C-141Bs, ordering more C-5s, continued purchases of KC-10s, and expansion of the Civil Reserve Air Fleet. This would allow it to perform the work done by the C-141, and to fulfill some of the duties of the Lockheed C-5 Galaxy, freeing the C-5 fleet for outsize cargo.Īlternative proposals were pursued to fill airlift needs after the C-X contest. Compared to the YC-15, the new aircraft differed in having swept wings, increased size, and more powerful engines. On 28 August 1981, McDonnell Douglas was chosen to build its proposed aircraft, then designated C-17. Lockheed submitted two designs, a C-5-based design and an enlarged C-141 design. Boeing bid an enlarged three-engine version of its AMST YC-14. McDonnell Douglas elected to develop a new aircraft based on the YC-15. The USAF set mission requirements and released a request for proposals (RFP) for C-X in October 1980. Compounding matters, USAF needed increased strategic airlift capabilities to fulfill its rapid-deployment airlift requirements. The McDonnell Douglas YC-15 design was used as the basis for the C-17.īy 1980, the USAF found itself with a large fleet of aging C-141 Starlifter cargo aircraft. The Air Force started the C-X program in November 1979 to develop a larger AMST with longer range to augment its strategic airlift. Though both entrants exceeded specified requirements, the AMST competition was canceled before a winner was selected. The Advanced Medium STOL Transport (AMST) competition was held, with Boeing proposing the YC-14, and McDonnell Douglas proposing the YC-15. Air Force began looking for a replacement for its Lockheed C-130 Hercules tactical cargo aircraft. 3.5 Strategic Airlift Capability program.The final C-17 was completed at the Long Beach, California plant and flown on 29 November 2015. ![]() Aside from the United States, the C-17 is in service with the air forces of India, United Kingdom, Australia, Canada, Qatar, United Arab Emirates, NATO Heavy Airlift Wing and Kuwait. It was designed to replace the Lockheed C-141 Starlifter, and also fulfill some of the duties of the Lockheed C-5 Galaxy, freeing the C-5 fleet for outsize cargo.īoeing, which merged with McDonnell Douglas in 1997, continued to manufacture C-17s for export customers following the end of deliveries to the U.S. The C-17 commonly performs tactical and strategic airlift missions, transporting troops and cargo throughout the world additional roles include medical evacuation and airdrop duties. ![]() The C-17 carries forward the name of two previous piston-engined military cargo aircraft, the Douglas C-74 Globemaster and the Douglas C-124 Globemaster II. It was developed for the United States Air Force (USAF) from the 1980s to the early 1990s by McDonnell Douglas. ![]()
