In another display of its commitment to national security, Pratt & Whitney Rocketdyne today successfully helped boost a satellite for the U.S. government from Cape Canaveral Air Force station, Fla. The satellite was onboard a United Launch Alliance Delta IV rocket, powered by Pratt & Whitney Rocketdyne’s RS-68 booster engine and an RL10B-2 upper-stage engine. Pratt & Whitney Rocketdyne is a United Technologies Corp. (NYSE:UTX) company.

“This is a proud moment for Pratt & Whitney Rocketdyne, knowing our engines are providing the heavy-lift capabilities needed to place this government asset into space,” said Dan Adamski, RS-68 program manager, Pratt & Whitney Rocketdyne. “We congratulate our United Launch Alliance customer on another successful launch, and look forward to working together in the future.”

Christine Cooley, RL10 program manager, Pratt & Whitney Rocketdyne, said, “The successful placement of the satellite into orbit by the RL10B-2 upper-stage engine would not be possible without the unwavering commitment of the RL10 team and its dedication to 100 percent mission success. I want to personally thank the team for their dedication and attention to detail.”

The RS-68 is a hydrogen-fueled engine designed for heavy-lift with 758,000 pounds of vacuum thrust and 663,000 pounds of sea-level thrust. The RL10B-2 is a cryogenic upper-stage engine that provides 465 seconds of specific impulse and 24,750 pounds of thrust.
