It should be noted that Roscosmos presented several variants of the Angara launch vehicle. One of them has a KVKT upper stage (oxygen-hydrogen), just for the launch of the Federation spacecraft. At the same time, the "Angara-A5V" launch vehicle itself is a three-stage one.
The first stage will consist of four lateral blocks URM-1M (universal missile modules), which will use RD-191M liquid engines (developed by NPO Energomash JSC). In the second stage, one RD-191M will be installed. The third stage will have two oxygen-hydrogen engines RD-0150.
It must be recalled that the Russian "Angara" is a whole family of launch vehicles of different classes. "Angara-1.1" and "Angara-1.2" - light, "Angara-A3" - medium, "Angara-A5" and "Angara-A5M" - heavy, and "Angara-A5V" - heavy with increased carrying capacity (up to 8 tons of payload). There is even a Angara-A7 project (up to 35 tons of payload).
The Roskosmos promise that the spacecraft Federation will leave for the first unmanned flight in 2022 on the Soyuz-5 launch vehicle (Irtysh) from the Baikonur cosmodrome (Kazakhstan). Irtysh is a middle-class LV being developed with the ability to launch 17 tons of payload into low Earth orbit.
For 2023, the Federation’s unmanned flight to the International Space Station (ISS) and automatic docking with the station are planned. In 2024, the spacecraft Federation will deliver the first crew to the ISS. As previously reported by the general director of Roskosmos Dmitry Rogozin, the first launch of the Angara-A5V launch vehicle from the Vostochny cosmodrome is due to take place in 2026.
