Overview

Why this aircraft matters

The prototype first flew in 1991 and the aircraft entered US Air Force service in 1993. Production ended in 2015, but the type remains in service with several nations and NATO.

Size and design

Externally blown flaps, a high-lift wing and reversible thrust enable short-field operation and ground manoeuvring that would be unusual for an aircraft of this size.

At 53 metres long and 51.75 metres across, the C-17 Globemaster III occupies a very different physical envelope from an everyday single-aisle airliner. Dimensions alone do not tell the entire story: payload, cabin volume and intended role determine how that space is used.

Operators and current status
