P&W Successfully Completes CDR on J-2X Rocket Engine

(Canoga Park, Calif., November 19, 2008) -- Pratt & Whitney Rocketdyne has taken a major step toward powering the nation's next-generation space launch vehicle with the completion of the J-2X engine Critical Design Review (CDR). Pratt & Whitney Rocketdyne is a United Technologies Corp. (NYSE: UTX) company.

Starting in 2014, the J-2X rocket engine will power the Ares I rocket into space, helping deliver the Orion crew exploration vehicle, its crew of astronauts and small payloads to the International Space Station. The J-2X will also power launch vehicles to the moon and beyond in coming decades. The heart of the J-2X is proven heritage technology that propelled the Apollo-era Saturn V rockets into space.

"The successful completion of the Critical Design Review is a major milestone in the development of the J-2X -- one of the safest, most affordable and highest performing rocket engines ever to be built," said John Vilja, J-2X program manager, Pratt & Whitney Rocketdyne. "It demonstrates our engineering design and development are on sound footing, and takes us another step closer to delivering the nation's next mode of space transportation."
