Transport and Cargo Aircraft. The name Globemaster III was officially applied to the C-17 on 5 February 1993 by the head of Air Mobility Command General Ronald R. Fogleman. The first unit to operate the C-17 was the 437th Airlift Wing at Charleston AFB, SC, which received its first aircraft on 14 June 1993. Within months of achieving Initial Operational Capability (IOC) entering service, in mid December 1995 the 437th deployed 12 of its C-17s to Rhein Main, Germany to take part in the huge airlift operation required to establish IFOR peacekeeping forces in Bosnia. The benefits of the C-17 were immediately apparent, as it carried much of the US Army’s heavy equipment into Tuzla Airport, where the C-5A was too heavy to operate safely. The reduced ramp space taken up by the C-17 compared to the C-5 was also appreciated. From the outside, the C-17 reveals little of its high technology design. C-17 Globemaster III (wallpaper 4).

It appears to be a conventional high-wing, four engined T-tailed jet transport. Inside it is a different story. The two-crew cockpit features digital displays and head-up displays. The aircraft is flown using a fighter-style control stick instead of the traditional yoke used on transport aircaft. The flying controls are managed by a quadruply redundant Fly-By-Wire control system with mechanical backup that operates 29 control surfaces – including an all-moving tailplane, two rudders, two ailerons, eight spoilers, four flaps and eight slats. The supercritical aerofoil section wing is swept at 25º and features prominent winglets, which improve aerodynamic efficiency at the wing tips. Hung off the wing on cantilevered pylons are four Pratt & Whitney PW2040 turbofan engines. Based on the engines used on the Boeing 757, they are known by the military designation F117-PW-100. Each engine nacelle includes a thrust reverser, whereby a section of the engine cowling slides backwards to allow engine exhaust to be directed upward and forward. This function gives the C-17 the ability to complete a 180 º turn on a 90 ft (27.86 m) wide runway and to be able to reverse up a 2 per cent slope. C-17 Globemaster III (wallpaper 4).
