Pratt & Whitney has received a $2.7 billion firm-fixed-price contract for F-117 engine sustainment support, the US Department of Defense announced on 4 October.

Certified at 40,400lbs of thrust, Pratt & Whitney’s F117 engine powers the C-17 Globemaster III aircraft.

In addition to supporting engines on the US Air Force’s C-17 fleet, this contract also covers foreign military sales operators including the UK, Canada, UAE, Kuwait, Qatar, India and Australia.

With four F117 engines powering each C-17, the aircraft can carry a payload of 160,600lbs, take off from a 7,600ft airfield, and fly 2,400 nautical miles unrefueled. The F117 engine is equipped with a directed-flow thrust reverser capable of being deployed in flight. On the ground, the thrust reverser can back a fully-loaded aircraft up a two-degree slope. The engine uses technical and material advancements such as second-generation single-crystal turbine materials, improved cooling management and thermal barrier coatings to lower operating temperatures.

The contract will run through to the end of September 2022.
