Aerojet's Engine Powers Delta II Second Stage for DigitalGlobe's WorldView-2
Satellite Mission Launch

SACRAMENTO, Calif., Oct. 8 /PRNewswire-FirstCall/ -- Aerojet, a GenCorp (NYSE:
GY) company, announced that its engine helped propel today's Delta II launch
vehicle from Vandenberg Air Force Base (VAFB) in California, putting the Ball
Aerospace-built WorldView-2 imaging satellite into orbit. The satellite will
collect and record high resolution commercial Earth imagery from space.

Under contract to the United Launch Alliance, Aerojet provides the Delta II
rocket's liquid second stage engine. The United Launch Alliance supplies the
Delta II launch vehicle and other mission services to Boeing Launch Services,
under contract with satellite imagery company, DigitalGlobe (NYSE: DGI).

This same engine has supported launches of critical NASA missions such as
MESSENGER, Phoenix Mars Lander, GLAST, THEMIS, STEREO, Deep Impact and the
Mars Exploration Rovers (MER) spacecraft as well as the USAF Global
Positioning System (GPS) Block IIR fleet. This particular engine's launch
history began in 1958 when Aerojet provided second stage propulsion for the
Vanguard-1 mission.

"It is a privilege to be part of such a great team that provides a high
reliability vehicle to both government and commercial users," said Richard
Yanick, director of Delta II and Space Tank Production Programs. "This is an
important mission for DigitalGlobe and we are glad to have played an important
role in their venture."
