The C-17 Globemaster is a 4-turbofan engine tactical heavy transport aircraft, developed by the American company Boeing IDS. The C-17 can support troops on the frontline by its capacity to land and takeoff from forward opoerating bases and unpaved runways. It was specially developed for the United States Air Force.
The Globemaster was developed by the more need of heavy transport and the new vehicles in the US Forces which became more heavier. It's the most advanced transport aircraft in the USAF and is very useful for peacekeeping operations and humanitary missions. The C-17's are in service with the Air Mobility Command from Charleston AFB, S.C. and operate by 437th Airlift Wing and the 315th Airlift Wing. The last wing is part of the US National Reserve.
