The RD-0236 (GRAU Index 15D114) is a liquid rocket vernier engine, burning N₂O₄ and UDMH in the gas generator cycle.^[3]^[1] It is used along the RD-0235 main engine on the UTTKh second stage, which was featured in the UR-100N ICBM as well as the Strela and Rokot launch vehicles derived from it. Its function is to supply thrust vector control by gimbaling each of its four nozzles in a plane.^[2] While the engine is out of production, the ICBM as well as Strela remain operational as of 2015.^[4] The Rokot launch vehicle conducted its final launch before retirement in December 2019.^[5]
