The GEM 63XL, developed by Northrop Grumman, is an extended version of the GEM 63, about 73 inches (190 cm) longer than its predecessor. [7] The weight is approximately 117,000 pounds (53 metric tons) each. [8] First fired in 2020, it is used on the Vulcan launch vehicle beginning with the first launch on January 8, 2024.
The Northrop Grumman XRQ-73 SHEPARD (Series Hybrid Electric Propulsion AiRcraft Demonstration) is an hybrid-electric Group 3 unmanned aerial vehicle (weighting about 1,250 lb (570 kg)) developed by Northrop Grumman.
Northrop Grumman is now manufacturing the booster separation motors for the Space Launch System Boosters, part of the NASA Space Launch System (SLS) for the Artemis program. [ 5 ] For Ariane 5 and Ariane 6 , a Norwegian-Finnish company Nammo manufactures similar but different booster separation motors.

[13] [14] On 5 June 2020, NASA awarded Northrop Grumman Innovation Systems a $187 million contract to complete the preliminary design of HALO. [15] NASA signed a separate contract with Northrop for the fabrication of the HALO, and for integration with the Power and Propulsion Element (PPE), being built by Maxar, for US$935 million.

All launch vehicle propulsion systems employed to date have been chemical rockets falling into one of three main categories: Solid-propellant rockets or solid-fuel rockets have a motor that uses solid propellants , typically a mix of powdered fuel and oxidizer held together by a polymer binder and molded into the shape of a hollow cylinder.
