Pratt & Whitney has been awarded a $2.7 billion contract for F-117 engine sustainment support.

Work is expected to be completed by Sept. 30, 2022. This contract involves foreign military sales to the United Kingdom, Canada, United Arab Emirates, Kuwait, Qatar, India, Australia and Strategic Airlift Capability, the US department of defense said in a statement Wednesday.

The current F117 engine—the reduced temperature configuration (RTC)—uses technical and material advancements such as second-generation single-crystal turbine materials, improved cooling management and thermal barrier coatings to lower operating temperatures. These enhancements contribute to the F117’s excellent reliability, durability and long time on-wing, according to Pratt and Whitney.

Pratt & Whitney’s F117 is the exclusive power for the U.S. Air Force’s advanced transport, the C-17 Globemaster III aircraft.
