Roscosmos and its subsidiary RSC Progress signed a state contract to create a draft project of a space rocket complex with Amur LPG-powered medium-class carrier rocket at the Vostochny Cosmodrome.
This space rocket complex is to be designed for the commercial market employing an LPG-liquid oxygen powered engines. The new rocket will have reusable first stage and liquid reusable engines that have been under development since 2016 by Chemical Automatics Design Bureau (KB Khimavtomatika, part of Roscosmos).
Maximal commercial orientation of the project suggests Russian space industry designs the first ever carrier rocket to stay within the preset launch service cost.
Amur medium class carrier rocket will have a number of technical features fully meeting world tendencies and developer requirements. For example, the rocket design will include an opportunity to use state-of-the-art technical solutions and materials: 2nd stage deep choke, larger payload fairing, composite fuel tanks, using new alloys, etc.
According to the preliminary calculations, the complex might start testing as early as in 2026. It is meant to gradually substitute the current Soyuz-2 carrier rocket family.
