Monopropellant Thrusters

Monopropellant ThrustersNorthrop Grumman has developed, qualified and flown nearly 1,000 monopropellant thrusters, gas generators and gas thrusters, ranging from 30 millipounds to 8 lbs. We have also developed and tested 15-pound class and larger monopropellant thrusters. In all cases, Northrop Grumman thrusters have exceeded design goals and outlived the useful spacecraft lives on a wide range of myriad of programs, including Pioneer 10 and 11, DSP, TDRS, FSC, Chandra X-ray Observatory, SOHO, EOS, TOMS, STEP, ROCSAT, KOMPSAT, and HEAO.
