The upgraded engine is already recognized as the most powerful in the world: with a mass of 10 tons, its thrust exceeds 800 tons.
At the same time, fire tests of the RD-191 rocket engine developed and produced by NPO Energomash for the Russian Angara launch vehicle have been successfully and fully carried out.
