Historical Partnership

WEST PALM BEACH, Fla., Oct. 18 /PRNewswire/ -- Pratt & Whitney Rocketdyne
today helped boost a Lockheed Martin-built meteorological satellite for the
U.S. Air Force into orbit from Vandenberg Air Force Base, Calif. The
satellite was aboard a United Launch Alliance Atlas V rocket powered by Pratt
& Whitney Rocketdyne's RL10 upper-stage engine and the RD AMROSS RD-180
booster engine.

Pratt & Whitney Rocketdyne is a unit of United Technologies Corp. (NYSE:UTX).
RD AMROSS LLC is a joint venture of Pratt & Whitney Rocketdyne and NPO
Energomash.

"Pratt & Whitney Rocketdyne congratulates United Launch Alliance on the
historical milestone of 600 Atlas launches, and we are proud to have been part
of the program since the first launch from Cape Canaveral Air Force Station,
Fla., in 1957," said Jim Maus, director, expendable propulsion programs, Pratt
& Whitney Rocketdyne.

"The AV-017 launch represents the 24th consecutive successful mission for the
RD-180 engine powering an Atlas launch vehicle," said Len Dest, president and
CEO of RD AMROSS.

The Atlas V launched the Defense Meteorological Satellite Program, F18
spacecraft for the U.S. Air Force. Built by Lockheed Martin, this
polar-orbiting weather satellite will be used by the military for strategic
and tactical weather prediction to aid the U.S. military in planning
operations at sea, on land and in the air.

The Atlas V Centaur upper stage is powered by a single RL10A-4-2 engine that
delivers 22,300 pounds of thrust. For more than 46 years, the RL10 has been
one of the United States' most reliable upper-stage engines. The Atlas V
booster stage is powered by the RD-180 engine delivering 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.
