ATK (Alliant Techsystems) said Alliant Aerospace Propulsion Company, Magna, Utah, successfully completed the second of three static test firings to qualify a new solid rocket motor for The Boeing Company’s Delta IV Medium-plus family of launch vehicles. The Delta IV vehicles are the latest derivative of the Delta family of rockets that has been lifting satellites into orbit since 1960. The new graphite epoxy motor, known as GEM-60, is designed to provide a lift capacity ranging between 12,890 and 14,475 pounds to geosynchronous transfer orbit (GTO) for the Delta IV Medium-plus family of vehicles. Jeff Foote, president, Alliant Aerospace Propulsion Company, said the new GEM-60 motor performed flawlessly during the second static firing. “The results achieved in the first two test firings indicate that we are squarely on track to qualify this important new solid rocket booster,” said Foote. “The GEM-60 development program has proceeded smoothly and on schedule from the very beginning, thanks to a strong partnership between Boeing and Alliant Aerospace Propulsion Company. We are looking forward to the final static test firing next month and the culmination of a great team effort.” The GEM-60 motors are manufactured at the group’s Utah Composites Center in Clearfield, Utah, and Utah Propulsion Center in Magna, Utah.
