    Notes
    JWST's integrated propulsion subsystem comprises four SCAT bipropellant thrusters for major orbit correction and station keeping plus eight hydrazine-only MRE-1 thrusters for attitude control and reaction-wheel momentum unloading. This relationship records one whole-subsystem installation; the component thruster count remains in notes.
