C-17A Globemaster III aircraft

The US Defense Security Cooperation Agency has notified Congress of a potential sale of 20 F-117-PW-100 engines for the UK Royal Air Force’s (RAF) fleet of eight C-17A Globemaster III aircraft as part of the Globemaster III Sustainment Partnership programme (GSP).

Under the estimated $300m foreign military sale (FMS), the air force has also requested engine exchange kits, support equipment, Global Positioning Systems (GPS), communications equipment, spare and repair parts, training and logistical support services.

The potential sale will ensure the UK effectively maintains its current force projection capability to enhance interoperability with US forces and will also provide the UK and other Nato forces with rapid global strategic mobility to deploy to austere locations.

Boeing will be the prime contractor.

The F117-PW-100 is a dual spool, axial air flow, annular combustion, high by-pass, turbo fan, dual channel FADEC computer controlled turbine engine developed from Pratt & Whitney’s PW2037 commercial engine which powers Boeing’s 757 jet airliner.

Around 239 C-17s featuring F117 engines have been delivered to the air forces of 25 international customers worldwide, including the US, UK, Qatar, Canada, Australia, UAE and the 12-member Strategic Airlift Capability initiative of Nato and Partnership for Peace nations.

The Boeing C-17 Globemaster III is a large military transport aircraft designed to conduct rapid strategic airlift of troops and palleted cargo to main operating bases or forward operating bases throughout the world.

The C-17 airlifter can be configured to perform tactical airlifts, medical evacuation and airdrop missions. The C-17 can also be deployed to help with humanitarian and disaster relief efforts.

The US Air Force’s (USAF) GSP programme is aimed at providing total aircraft sustainment support under a single contract order to improve mission readiness, while reducing operating and support costs.
