In 2025, rocket engines manufactured by the Samara-based enterprise "ODK-Kuznetsov" (part of the United Engine Corporation of the Rostec State Corporation) were used in 13 launches of Soyuz-2 family launch vehicles. The launches were carried out from three Russian cosmodromes: Baikonur, Vostochny, and Plesetsk.
Of the total number of launches, 12 were of the Soyuz-2.1a and Soyuz-2.1b modifications, equipped with RD-107A and RD-108A engines on the first and second stages, respectively. Another launch was carried out using the NK-33A engine on the first stage of the light Soyuz-2.1v rocket. All missions were completed successfully: satellites of various purposes were put into orbit, and cargo and crews were delivered to the International Space Station (ISS).
In particular, ODK engines played a key rolein sending members of the 73rd and 74th long-term expeditions to the ISS, as well as three cargo ships that ensure the station's life support.
The launch on August 20 from the Baikonur Cosmodrome attracted particular attention: the Soyuz-2.1b rocketplaced the Bion-M No. 2 scientific apparatus into polar orbit. Its mission is aimed at studying the influence of conditions close to deep space on living organisms.
The final event of the year was the launch on December 28 from the Vostochny Cosmodrome, during whicha group of 52 satellites was launched into orbit - both Russian and foreign, including CubeSat format devices. This launch was the twentieth for the Amur cosmodrome.
It is worth recalling that RD-107A and RD-108A engines manufactured by ODK-Kuznetsov are traditionally installed on the first and second stages of all Soyuz family carriers. The thrust of the RD-107A at the Earth's surface is 85.6 tons-force, the specific impulse in vacuum is 320.2 seconds. For the RD-108A, these parameters are 80.8 tf and 320.6 s, respectively.
