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]
