Pratt & Whitney Rocketdyne and RD AMROSS successfully propelled a critical U.S. government satellite into orbit on Sept. 13, once again demonstrating the consistency and reliability of their rocket launch propulsion systems.  The spacecraft launched from Vandenberg Air Force Station in California on a United Launch Alliance Atlas V rocket.  The Atlas V is powered by the RD AMROSS RD-180 booster engine, and the upper-stage is powered by the Pratt & Whitney Rocketdyne RL10 engine.

The Atlas V Centaur upper-stage is powered by a single RL10A4-2 engine that delivers 22,300 pounds of thrust.  The Atlas V Common Core booster is powered by the RD-180 engine and delivers nearly 1 million pounds of thrust.  The RD-180 is fueled by a kerosene/liquid oxygen mixture, provides an environmentally-clean operation, and uses an extremely efficient, high-pressured staged combustion cycle.  The high-pressure helium storage tanks on the Atlas V booster and upper stage were manufactured by ARDE, Inc., located in Carlstadt, N.J., a division of Pratt & Whitney Rocketdyne.

Pratt & Whitney Rocketdyne upperstage propulsion successfully orbited the second in a series of Advanced Extremely High-Frequency (AEHF) communications satellites for the U.S. military, once again demonstrating the consistent reliability of its power and propulsion systems. The spacecraft was launched from Cape Canaveral Air Force Station in Florida by a United Launch Alliance Atlas V rocket. The Atlas V is powered by the RD AMROSS RD-180 booster engine, and the upper-stage is powered by the Pratt & Whitney Rocketdyne RL10 engine.

The AEHF is a joint service satellite communications system that will provide global communications for military troops within all services of the U.S. Department of Defense. The spacecraft will be used to relay highly secure and jam-resistant communications for the Armed Forces of the United States, the British Armed Forces, the Canadian Forces and the military of the Netherlands. When fully deployed, the system will consist of four spacecraft that travel in geostationary orbits.

The Atlas V Centaur upper-stage is powered by a single RL10A4-2 engine that delivers 22,300 pounds of thrust. The Atlas V Common Core booster is powered by the RD-180 engine and delivers nearly 1 million pounds of thrust. The RD-180 is the only liquid oxygen/kerosene-fueled engine with an oxygen-rich staged-combustion cycle flying in the United States today.

Pratt & Whitney Rocketdyne once again demonstrated the consistent reliability of its propulsion systems by successfully powering the Centaur upper-stage rocket on its 200th mission and placing the first in a series of Mobile User Objective System (MUOS) communications satellites for the U.S. Navy into orbit. The payload launched from Cape Canaveral Air Force Station in Florida on a United Launch Alliance Atlas V rocket. The Atlas V is powered by the RD AMROSS RD-180 booster engine, and the Centaur is powered by the Pratt & Whitney Rocketdyne RL10 engine.

The Atlas V Centaur upper stage is powered by a single RL10A4-2 engine that delivers 22,300 pounds of thrust. The Atlas V Common Core booster is powered by the RD-180 engine and delivers nearly 1 million pounds of thrust.

Pratt & Whitney Rocketdyne to Power Centaur Rocket Mission

Pratt & Whitney Rocketdyne will power the Centaur upper-stage rocket on its 200th mission and to place the first in a series of Mobile User Objective System (MUOS) communications satellites for the U.S. Navy into orbit on Feb. 16. The launch is scheduled to take off from Cape Canaveral Air Force Station, with a Pratt & Whitney Rocketdyne RL10A4-2 engine providing the upper-stage propulsion.

The payload will launch from Cape Canaveral Air Force Station in Florida on a United Launch Alliance Atlas V rocket. The Atlas V is powered by the RD AMROSS RD-180 booster engine, and the Centaur is powered by the Pratt & Whitney Rocketdyne RL10A4-2 engine, which delivers 22,300 pounds of thrust.

Editor's note: The launch has been rescheduled for Friday, Feb. 24.

Pratt & Whitney Rocketdyne Boosts Latest Mars Rover to the Red Planet

WEST PALM BEACH, Fla., Nov. 26, 2011 – Pratt & Whitney Rocketdyne demonstrated the consistent reliability of its power and propulsion systems by successfully boosting the Mars Science Laboratory rover, which will travel to the red planet to assess its habitability. The mission launched from Cape Canaveral Air Force Station in Florida by a United Launch Alliance Atlas V rocket. The Atlas V is powered by the RD AMROSS RD-180 booster engine, and the Centaur upper stage is powered by the Pratt & Whitney Rocketdyne RL10 engine.

The Atlas V Centaur upper stage is powered by a single RL10A4-2 engine that delivers 22,300 pounds of thrust. The Atlas V Common Core booster is powered by the RD-180 engine and delivers nearly 1 million pounds of thrust. The RD-180 is the only liquid oxygen/kerosene fueled engine with an oxygen-rich staged-combustion cycle flying in the United States today.
