Exclusive Power for the C-17 Globemaster III Transport
Pratt & Whitney’s F117-PW-100 engine is a member of the PW2000 family of commercial engines. Certified at 40,440 pounds of
thrust, the F117 was selected by the U.S. Air Force as the exclusive powerplant for the C-17 Globemaster III, an advanced
four-engine transport. The F117 engines are 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. It is also noteworthy that the F117-powered
C-17 set 22 world records during qualification testing before initial operating capability (IOC).
RELIABILITY DEPENDABILITY
Pratt & Whitney’s F117 engines have accumulated more than Four F117 engines power each C-17 Globemaster III, and has
18 million flight hours in support of military and humanitarian consistently proven itself as a world-class, dependable engine in
missions around the globe. The world’s ever-changing geopolitical military service. Pratt & Whitney’s ongoing investment in product
landscape requires military flexibility. Whether it’s an airlift mission, improvements has enabled the engine to continuously surpass
