Universal Rocket Module (URM) is the modular liquid fuelled first stage of the Angara expendable launch system. Depending on configuration, the first stage can consist of 1, 3, 5 or 7 URMs. Each URM uses Russian-made RD-191 engine burning RP-1 fuel with liquid oxygen producing a thrust of 1.92 MN. [1]

The Naro-1 launch vehicle is based on the Universal Rocket Module with the de-rated RD-151 engine, combined with a solid-fueled second stage built by South Korea.
