The Air Force on Sept. 27 awarded Boeing [BA] a contract that could be worth nearly $3.5 billion over the next decade for C-17 sustainment under the long-term C-17 Globemaster III Integrated Sustainment Program (GISP).

“This contract will provide support and sustainment services to the government product support manager/product support integrator for the C-17 weapon system,” DoD said in a contract announcement. “Support includes, but is not limited to: program management; sustaining logistics; material and equipment management; sustaining engineering; quality assurance; depot level aircraft maintenance and modifications; F117 propulsion system management; long-term sustainment planning; field services, unique foreign military customer services and Air Logistics Center partnering support for the worldwide fleet of the C-17 aircraft.”

Pratt & Whitney [RTX] builds the F117 engine for the C-17.

“The contract involves Foreign Military Sales (FMS) to the United Kingdom, Australia, Canada, NATO Airlift Management Program Office, India, Kuwait, United Arab Emirates and Qatar,” per the DoD contract announcement on Sept. 27.

The C-17 proved to be a bulwark for the evacuation of U.S. forces and Afghan civilians in the recent withdrawal from Afghanistan.
