Aerojet’s liquid second-stage engine helped power the United Launch Alliance Delta II launch vehicle and its satellite payload in a launch today from Vandenberg Air Force Base, Calif. The Delta II vehicle, known as the workhorse of the launch industry in its payload class, carried a classified payload for the U.S. National Reconnaissance Office.

Aerojet’s Delta II second stage engines are among the world’s most reliable and were called upon once again to complete a mission important to national security. This launch marks the 254th successful Delta launch to date using Aerojet’s second-stage engines. Aerojet, a GenCorp Inc. (NYSE: GY – News) company, has provided second stage engines for the Delta II since 1982.

Aerojet’s second stage liquid rocket engine has a record of unblemished success and owes its longevity to a robust design and the use of proven components that have evolved over the engine’s lifetime to enhance performance and meet customer requirements. Aerojet’s second-stage engine support of the Delta II will continue through at least 2010.

Aerojet is a world-recognized aerospace and defense leader principally serving the missile and space propulsion, and armaments markets. GenCorp is a leading technology-based manufacturer of aerospace and defense products and systems with a real estate business segment that includes activities related to the entitlement, sale, and leasing of the Company’s excess real estate assets.
