С 2*рд-58 доразгона и орбитального маневрирования
The Buran spacecraft used two of an evolution of the RD-58M, called 17D12, as its main orbital correction engines. Instead of RG-1, it burned Syntin, and could be ignited 15 times.[11][12] It is assumed that it was the base for the RD-58S, which had practically the same specifications and powered the Blok DM-2M.[13] But the manufacturer states that the engine is compatible with both propellants.[1]
