Engine maker Pratt & Whitney delivered the first PW4062 jet engines for the first KC-46 test aircraft during an event at Boeing’s Everett, Washington, facility this week.
The Boeing KC-46 is a military aerial refueling and strategic transport aircraft developed by Boeing from its 767 commercial jet airliner. In February 2011, the tanker was selected by the United States Air Force(USAF) as the winner in the KC-X tanker competition to replace older KC-135 Stratotankers.
Two Pratt & Whitney PW4062 jet engines, each with a 94-inch fan blade diameter, will power each U.S. Air Force KC-46A aerial tankers. The program’s scope, if fully exercised, calls for as many as 368 PW4062 engines to be delivered between 2013 and 2027. Actual production engine procurement quantities will be determined over the life of the program as established by future purchase orders.
Pratt & Whitney has delivered more than 2,500 PW4000-94” engines that have collectively logged more than 120 million flight hours on commercial aircrafts around the world.
The PW4062 is the highest thrust model in Pratt & Whitney’s PW4000-94” commercial engine family and is offered for both commercial freighter and military applications. The two PW4062 engines that will power the KC-46A each deliver 62,000 pounds of thrust.
The PW4000 engine family has an outstanding safety record, high reliability, excellent performance and low maintenance costs. The PW4000-94” family meets emissions and noise regulations, and offers superior fuel economy and maintainability. The PW4000-94” engine operates commercially on the Boeing 767, MD-11 and earlier Boeing 747 models.
