Throughout eleven and a half months of 2021, Russian carrier rockets performed 23 space launches (all successful). Twenty-two of these launches employed liquid-propellant rocket engines developed by NPO Energomash (a part of Roscosmos). The only exception was the Soyuz-2.1v light rocket, which does not use engines developed by Energomash.

As usual, the leaders in the number of launches are two modifications of the Soyuz-2 launch vehicle: thirteen launches of 2.1b type and seven launches of 2.1a type, each using four RD-107A liquid rocket engines in the first stage and one RD-108A in the second stage. In addition, two launches of the Proton-M carrier rocket took place powered by six RD-253 family engines in the rocket’s first stage.

The RD-180 liquid-propellant rocket engines provided ensured four launches of the American Atlas 5 rockets and the RD-181 engines provided two launches of the American Antares rockets.

A total of one hundred and twenty engines developed by Energomash worked in 28 launches in 2021 so far: one hundred RD-107/108 family liquid-propellant engines, twelve RD-253 family engines, four of the RD-181, and four of the RD-180.

130 space orbital launches have been conducted so far in 2021, of which 21.5% have been powered by NPO Energomash engines. Since the launch activities in December 2021 will continue, the full results for 2021 can only be summarized at the beginning of the next year.
