RD-0237
The RD-0237 (GRAU Index 15D114) is a pressure-fed liquid rocket vernier engine, burning N2O4 and UDMH.[1] It is used on the UR-100UTTKh MIRV vehicle to supply thrust vector control by gimbaling of its nozzle.[2] While the engine is out of production, the ICBM and Strela remain operational as of 2015.[3]
