Launch Vehicle Propulsion

L3Harris propulsion systems are featured on the launch vehicles that carry the nation’s most important payloads into space, from missile warning satellites to classified intelligence payloads to constellations of small satellites for national security. We supply upper-stage engines for ULA’s Vulcan Centaur and Atlas V launch vehicles, as well as main and upper stage engines for NASA’s Space Launch System. We are also developing a new family of engines, Bantam, to lower the cost of space access by maximizing the use of 3D printing and reducing complexity while maintaining reusability and reliability.
