The Boeing C-17 Globemaster is a large military transport aircraft. It was developed for the United States Air Force (USAF) from the 1980s to the early 1990s by McDonnell Douglas. The C-17 carries the name of two previous piston-engined military cargo aircraft, the Douglas C-74 Globemaster and the Douglas C-124 Globemaster II. The C-17 commonly performs strategic airlift missions, transporting troops and cargo throughout the world; additional roles include tactical airlift, medical evacuation and airdrop duties. Boeing, which merged with McDonnell Douglas in the 1990s, continues to manufacture C-17s for export customers following the end of deliveries to the U.S. Air Force. The C-17 is operated by the U.S. Air Force, the United Kingdom, Australia, Canada, Qatar, United Arab Emirates, NATO Heavy Airlift Wing, and India.
