The Qatari armed forces will take delivery of the first of two C-17 Globemaster III aircraft, which can be used for transporting troops and heavy equipment, next summer.

Doha has also signed an agreement for logistics support with the US Air Force. The deal encompasses spare parts and repairs, supply of support equipment as well as publications and technical data.

The US Air Force and Boeing will also provide flight engineer training, supply communications equipment, provide maintenance and other related logistical support. If all options on the deal are exercised, the estimated cost is $400m.

Qatar is the fourth foreign customer for the C-17 Globemaster III, after the UK, Canada, and Australia.
