The US Department of Defense (DOD) as awarded a contract worth up to $11.7 billion to Boeing for support and maintenance of its C-17 aircraft to the US military and global allies. The award comes less than a week after the Chicago-based company won a contract modification worth up to half a billion for similar services.

Boeing will have the opportunity to bid on task orders issued from DOD under the C-17 Globemaster II Integrated Sustainment Program, which was established as a way to roll support and maintenance for the global fleet of C-17 aircraft — including those acquired by international allies — under a single contract. About 10 per cent of this contract will support foreign military sales to United Kingdom, Australia, Canada, United Arab Emirates, Qatar and an alliance of NATO members known as the NATO strategic airlift capability. DOD noted that at this time, no dollars have been obligated.

On September 28, DOD announced a $469 million contract modification to Boeing, to provide similar support services for its C-17 aircraft to the Indian Air Force.
