The Fregat-MT, outfitted with an S5.95 engine, provided up to 4,460 pounds-force (about 20 kilonewtons) of vacuum thrust over multiple firings to deliver the EKS-2 satellite to its drop-off spot. EKS-2, which has its own propulsion system, will fine-tune its orbit over the coming days to place itself in its desired Tundra orbit.
