MRE-4 Monopropellant Thruster
For more than 25 years, TRW monopropellant thrusters have provided continous
on-orbit delta velocity and attitude control service for a variety of
spacecraft. All thrusters share the unique TRW head design, utilize
Shell 405 catalyst, and incorporate bed loadings consistent with long life.
