Northrop Grumman has a heritage of propulsion system flight successes with more than 90 liquid propulsion systems meeting or exceeding mission goals since 1958. Northrop Grumman's flight-proven heritage ranges from the TDRSS Flight 1 hydrazine system that raised this satellite to operational altitude using 1 lbf thrusters after an upper stage failure, to the system for NASA's Chandra X-ray Observatory
, that features over-wrapped, thin-wall propellant tanks and the highest performing dual-mode liquid apogee engines ever flown.
Northrop Grumman also has developed propulsion systems for kinetic kill vehicles, missiles and ejection seats. Our gel propulsion system provides smart flight for tactical missile systems.
