The McDonnell Douglas/Boeing C-17 Globemaster III is a large military transport aircraft that was developed for the United States Air Force from the 1980s to the early 1990s by McDonnell Douglas.
The C-17 carries forward the name of two previous piston engine military cargo aircraft, the Douglas C-74 Globemaster and the Douglas C-124 Globemaster II.
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.
It was designed to replace the Lockheed C-141 Starlifter, and also fulfil some of the duties of the Lockheed C-5 Galaxy.
Boeing, which merged with McDonnell Douglas in 1997, continued to manufacture C-17 aircraft after the merger.
The transport is in service with the USAF along with air arms of India, the United Kingdom, Australia, Canada, Qatar, the United Arab Emirates, Kuwait, and the Europe-based multilateral organization Heavy Airlift Wing.
The final C-17 was completed at the Long Beach, California plant and flown on 29th of November 2015.
Initial military airlifter version.
Unofficial name for C-17As with extended range due to the addition of the centre wing tank.
This upgrade was incorporated in production beginning in 2001 with Block 13 aircraft.
This software/hardware upgrade was a major improvement of the improved Onboard Inert Gas-Generating System, a new weather radar, an improved stabilizer strut system and other avionics.
A proposed tactical airlifter version with double-slotted flaps, an additional main landing gear on the centre fuselage, more powerful engines, and other systems for shorter landing and take-off distances.
