Aerojet, a GenCorp (NYSE:GY) company, congratulates the United Launch Alliance and all of its industry partners on the 50th anniversary of the Delta rocket’s inaugural launch.

The Delta rocket was originally designed as an interim launch vehicle with only a dozen launches planned. With close to 350 launches since May 13, 1960, this month marks the 50th anniversary of this powerhouse Delta vehicle. The Delta family of expendable launch vehicles is known as one of the most successful flight vehicles of any rocket currently in use.

The United Launch Alliance manages the Delta II program today. Aerojet, under contract to the United Launch Alliance, provides the Delta II rocket’s second stage liquid engine. The company’s engines have supported several hundred Delta missions to include critical NASA missions such as the Mars rovers Spirit and Opportunity, 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 and several missions for the National Reconnaissance Office.

“Aerojet is proud to have provided its second stage engine for Delta missions throughout the last 50 years,” says Richard Yanick, Aerojet’s director of Delta II and Space Tank Production Programs.
