Director General of the state corporation Roscosmos Dmitry Rogozin, according to TASS, shared details about the project of the Russian super-heavy rocket.
We are talking about the Yenisei complex. This carrier is planned to be used as part of future long-term space missions - for example, to explore the Moon, Mars, etc.
According to Mr. Rogozin, the super-heavy missile will be designed on a modular basis. In other words, the carrier stages can have dual or even triple uses.
In particular, the first stage of the super-heavy rocket will consist of five or six blocks, which are the first stage of the Soyuz-5 medium-class rocket. Power unit - RD-171MV.
For the second stage of the Yenisei, it was proposed to use the RD-180 engine. Well, the third stage is planned to be borrowed from the Angara-5V heavy rocket with increased payload.
In addition, Dmitry Rogozin announced the estimated cost of creating a super-heavy rocket. βI can tell you the minimum amount, but this is the amount of the first launch. The cost of all work, including the creation of a super-heavy class launch pad, the creation of a rocket, its preparation for launch, and the launch itself with a mock-up, not even with a ship, is approximately 740 billion rubles, βsaid the head of Roscosmos.
Last year, Russian President Vladimir Putin spoke about the need to develop a super-heavy-class missile system at a meeting with the leadership of Roscosmos. For the carrier, it is planned to form the necessary infrastructure at the Vostochny cosmodrome.
It is assumed that the final version of the technical appearance of the superheavy class carrier and the feasibility study of the project will be developed by November this year.
As for flight tests of the carrier, they will begin no earlier than 2028. Thus, the first targeted launches should be expected only in the 2030s.
