The company developed this new side-mounted rocket motor to add power to the United Launch Alliance (ULA) Atlas V launch vehicle. <\/p>\n<p>The maximum thrust of the GEM 63 is 373,000 pounds or roughly the equivalent of five B-2 Spirit bombers. Up to five GEM 63 motors can support a single Atlas V launch. <\/p>\n<p>The GEM 63 team developed the motor under a cooperative development program with ULA. Northrop Grumman has been supplying solid propulsion motors for a variety of launch vehicles since 1964 and is ULA&#8217;s largest legacy supplier of solid propulsion. Northrop Grumman&#8217;s expertise in solid rocket boosters combined with ULA&#8217;s history of reliability results in a strong partnership that guarantees assured access to space for national security. <\/p>\n<p>The first ground test, conducted in September 2018, qualified the motor for use as a strap-on booster for the Atlas V. This second test satisfies additional requirements for certification by the U.S. Air Force. The first launch using GEM 63 motors will take place in 2020. <\/p>\n<p>In addition to the GEM 63 motor, Northrop Grumman is also developing a GEM 63XL motor for ULA&#8217;s Vulcan Centaur rocket. Both versions of the GEM 63 family use common materials and processes to maintain a high-reliability, low-cost product. The first GEM 63XL case, which is the longest non-segmented, monolithic case ever manufactured, has already been wound at a new facility in Clearfield, Utah, and is currently in the structural qualification process. <\/p>\n<p>Video Credit: Northrop Grumman<\/p>\n<p class=\"MsoNormal\" style=\"margin: 5px;\">&nbsp;<\/p>\n<p class=\"MsoNormal\" style=\"margin: 5px;\">&nbsp;<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Northrop Grumman Corporation conducted its second ground test of a 63-inch diameter Graphite Epoxy Motor (GEM 63) in Promontory, Utah.
