Roscosmos launches production of the most powerful rocket engines  

NPO Energomash (Roskosmos subsidiary) starts production of the world’s most powerful liquid-propellant rocket engines – RD-171MV. They are designed for the first stage of the new Soyuz-5 rocket and the superheavy Yenisei rocket.

It is planned to spend about 19.5 million rubles on production. Fire tests of the engine will have to be carried out by the end of the year, and in 2021 the first engine for flight tests as part of the Soyuz-5 rocket will be delivered. It is expected that the first launch will take place in November 2022.

Development of the Soyuz-5 spacecraft

In 2016, development of a new Russian medium-class spacecraft Soyuz-5 (“Irtysh”) was started to replace the “Zenit” manufactured in Ukraine. It is planned to use on the first stage of the Soyuz-5 rocket the RD-171MV – an upgraded engine from the first stage of the Zenit rocket, and on the second stage two RD-0124MS – upgraded engines from the third stage of the Soyuz-2.1b instead of the RD-120 engines manufactured in Ukraine.

In July 2018, Roskosmos signed a state contract with RSC Energia (the leading developer of the Soyuz-5 rocket) for 61.2 billion rubles for construction and test of Soyuz-5. As part of the flight tests in 2022-2025, it is planned to perform four Soyuz-5 launches from Baikonur. In the first launch in 2022, the Soyuz-5 rocket will be launched with a DM launching unit and a spacecraft model. In 2023, it is planned to launch in unmanned mode a new-generation manned transport spacecraft “Federation”, and in 2024, in manned mode. The Soyuz-5 rocket will be manufactured at the “Progress” Rocket and Space Centre.
