From missiles that protect the homeland to rocket motors that provide access to space, power exploration and promote discovery, we are providing advanced propulsion systems our customers need now.\u201d<\/p>\n<p>Northrop Grumman is investing in technology and scaling its facilities to deliver critical propulsion capabilities. The company is nearing completion on several new solid rocket motor manufacturing facilities that will support production of multiple propulsion products, including the GEM boosters. The newly constructed buildings will support nearly every phase of SRM manufacturing including propellant mixing and casting, composite case manufacturing, final assembly and integration of subcomponents, material storage and motor shipping. The expansion of the company&#8217;s manufacturing facilities will augment existing capabilities and support increased production rates for several programs and customers including GEM boosters for ULA.<\/p>\n<p>Northrop Grumman has supplied rocket propulsion to ULA and its heritage companies for various launch vehicles since 1964. The GEM family of strap-on motors started in the early 1980s with the GEM 40, which supported 132 Delta II launches with over a thousand motors. To date, 32 GEM 63 boosters have supported nine Atlas V launches and two GEM 63XL boosters supported the inaugural flight of ULA\u2019s Vulcan Centaur rocket.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Five Northrop Grumman Corporation 63-inch-diameter Graphite Epoxy Motor (GEM 63) solid rocket boosters helped successfully launch the U.S. Space Force (USSF)-51 mission for the USSF Space Systems Command aboard a United Launch Alliance (ULA) Atlas V rocket.
