The Graphite-Epoxy Motor (GEM) is a family of solid rocket boosters first developed in the late 1980s and used from 1990 to the present day. GEM motors are manufactured with carbon-fibre-reinforced polymer casings and a fuel consisting of HTPB-bound ammonium perchlorate composite propellant. GEM is currently produced by Northrop Grumman Space Systems. GEM boosters were previously used on the Delta II, Delta III, and Delta IV launch vehicles, and are currently used on the Atlas V. A new variant, the GEM 63XL, is slated to fly as part of the Vulcan Centaur launch vehicle as early as 2022.
