Glushko had built the RD-109, intended for the second stage of a Lox/UDMH version of the R-7. Glushko expected to improve engine specific impulse by 8 to 10 seconds over that of the Lox/Kerosene R-7 engines. The project was abandoned because of Korolev's refusal to use such a toxic fuel. Based on RD-109. However Glushko was able to have the engine adopted for the second stage of the Kosmos space launcher.
