Commercial Solid Rocket Motors
Defining possible for national security, science and commercial launch missions.
Northrop Grumman’s commercial solid rocket motor products build upon flight-proven heritage and leverage commonalities to continuously improve and expand motor families at a low-cost and with high reliability and repeatable performance.
Graphite Epoxy Motors (GEM)
Northrop Grumman began developing the Graphite Epoxy Motor (GEM) in the early 1980s with the GEM 40 to increase launch capability for the Delta II launch vehicle, followed by the GEM 46, used on the Delta III and Delta II Heavy, and GEM 60 for the Delta IV Medium-Plus vehicle. The fourth-generation GEM 63 booster flew its inaugural flight on the Atlas V in November 2020, and the company began testing the extended-length GEM 63XL variant, the longest monolithic rocket motor produced to date, in August 2020 to serve the Vulcan Centaur vehicle.
Northrop Grumman continues to incorporate updated technologies and its unique filament winding process to leverage heritage, flight-proven designs for high quality, low-cost and reliable strap-on booster variations.
