Export restricted (ITAR), sale only to US Citizens and Organizations. Scarce R-6C attitude control bipropellant satellite engine manufactured by Kaiser Marquardt. The small thruster measures 6″ x 12″, with a 2″ diameter nozzle, and the opposing Marquardt Co. valves etched with nearly identical part numbers, “Valve Sol. Op., P/N T239650,” with serial numbers “003” and “004.” Designed for Earth-orbiting satellite applications, the R-6C qualified in 1981 for the Insat 1, ArabSat 1, and Olympus and HS-393-type satellites. In fine condition. An appealing satellite engine that, given its size and impressive engineering, is primed for display.
Originates from the personal collection of a former facility maintenance manager at Marquardt Corporation in Van Nuys, California.
