Das R-4D ist ein kleines Lageregelungstriebwerk, welches für die Apollo-Mondlandefähre (Lunar Module) und das Apollo-Servicemodul von der Marquardt Corporation entwickelt wurde. Es verwendet als hypergolen Treibstoff Stickstofftetroxid und Hydrazin und erzeugt einen Schub von 490 N, der spezifische Impuls beträgt 312 s. (de) The R-4D is a small hypergolic rocket engine, originally designed by Marquardt Corporation for use as a reaction control system thruster on vehicles of the Apollo crewed Moon landing program. Today, Aerojet Rocketdyne manufactures and markets modern versions of the R-4D. (en) R-4D thruster adalah mesin roket hypergolic kecil yang dirancang oleh Kasier Marquardt awalnya untuk program bulan Apollo. Hari ini, Aerojet Rocketdyne memproduksi dan memasarkan versi modern dari R-4D. Dikembangkan sebagai kontrol sikap thruster untuk Apollo Service and Lunar Modules tahun 1960-an. Setiap unit untuk modul mempekerjakan empat cluster quadruple (polong). Ini pertama kali diterbangkan pada Apollo 201 pada bulan Februari 1966. Sekitar 800 diproduksi selama program Apollo.
