Pratt & Whitney F117 engines surpass 10 million flight hours on C-17 fleet

Pratt & Whitney’s F117 engine, the exclusive power for the Boeing C-17 Globemaster III airlifter, recently exceeded 10 million engine flight hours. At the same time, the C-17 exceeded 2.5 million flight hours while supporting military and humanitarian mission in support of U.S. and allied troops around the globe. Since 2006, Pratt & Whitney’s F117 engines have accumulated more than six million flight hours in support of worldwide air mobility missions. To put this in perspective, it took 13 years of operational service for the engine to reach its first four million flight-hour milestone. This statistic reflects the C-17’s increased workload over the past several years.
