The RD-0237 (Russian: Ракетный Двигатель-0237, romanized: Raketnyy Dvigatel-0237, lit. 'Rocket Engine 0237', GRAU index: 15D114) is a vernier thruster engine used on liquid-fueled rockets burning a hypergolic mixture of unsymmetrical dimethylhydrazine (UDMH) fuel with dinitrogen tetroxide (N2O4) oxidizer, pressure-fed to the engine. It is used on the UR-100UTTKh MIRV vehicle to supply thrust vector control by gimbaling of its nozzle. While the engine is out of production, the ICBM and Strela remain operational as of 2015.
