Propulsion Technologies

PT-15025 001 150x89 Northrop Grumman has been advancing propulsion technology since 1958. Our earliest work involved cold gas, heated gas, and liquid bipropellant and monopropellant rockets and boosters; we continue to further these technologies today. For example, Northrop Grumman was selected in May 2001 by NASA to be one of the developers of new propulsion technology for potential use on next-generation launch and space transportation vehicles.

We have been developing electric propulsion since the 1970s and have made recent world-class advances in gel propellant propulsion.

Our fundamental research and development has been applied to a range of flight hardware for a wide range of space missions. Recent flight successes of propulsion systems have included NASA's Chandra X-ray Observatory, the Army's gel-powered FMTI missile, and a SCAT-powered spacecraft.
