MRE-4 Monopropellant Thruster (TRW)
For more than 25 years, TRW monopropellant thrusters have provided continuous 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.
