Pratt & Whitney is set to deliver the final production F117 engine to power the US Air Force's (USAF) Boeing-built C-17 Globemaster III strategic military transport aircraft.
Marking the completion of the programme, the 1,313th engine will be delivered at the company's engine centre in Middletown, Connecticut, US.
Pratt & Whitney Military Engines president Bennett Croswell said: "This is a bittersweet occasion for those of us who have played a part in developing and delivering the F117 engine to our customers over the years.
"The F117 production engine programme might be ending, but we look forward to working with our customers around the world to sustain their engines and to keep the C-17 fleet flying for decades to come."
A member of Pratt & Whitney's PW2000 family of commercial engines, the F117-PW-100 is a dual-spool, high-bypass turbofan aero engine equipped with a dual-channel full authority digital engine control (FADEC) system.
The C-17 Globemaster made its maiden flight in 1991 while The F117 engine first entered service in 1993.
Four F117 engines power the C-17, and each engine is rated at 40,440lb of thrust which enables the aircraft to carry a payload of 164,900lb and fly 2,400nm without refuelling.
Currently, F117 engines power C-17 fleets in Australia, Canada, Qatar, UAE, India, Kuwait and the US, besides the fleet in Nato Airlift Management Programme.
