It also follows from the presentation that the new rocket will become more profitable for Soyuz in terms of launches. At the moment, the cost of launching Soyuz-2.1b is $ 45 million. At the same time, sending into space a fellow for LNG will cost 40,5 million.
If we compare the carrying capacity of missiles, then here again the leaders are a promising carrier. The apparatus with a methane engine will be able to put 9 tons into low Earth orbit, and 2,2 tons into geo-transitional orbit. At Soyuz-2.1b, these indicators are 8,2 and 2 tons, respectively.
Recall that the plans for the development of a new rocket with a methane engine, which will be able to remove cargo up to 9 tons and will replace the "Union", Rogozin said back in May this year. At the same time, he repeatedly emphasized that the use of methane as a fuel will make it possible to create reusable devices.
Earlier, in July 2018, NPO Energomash announced the development of a methane engine. The unit was named RD-169 and can be tested after 3-4 years.
