He noted that the SpaceX company creates the Raptor engine on components oxygen and methane or as it is accepted in the Russian classification — the scheme "gas-gas". In schemes of this sort pressure level in the combustion chamber sounded by Musk is not something outstanding — in the developments for these schemes Energomash we put pressure level in the camera more than 300 atmospheres. At the same time the parameter of pressure in the camera is not output characteristic of the engine, such as draft and specific impulse. "Mister Musk, without being the technical specialist, does not consider that in the RD-180 engine for the carrier rocket Atlas other fuel scheme — "oxygen-kerosene" is used absolutely, and these are other operation parameters of the engine.

"Today Raptor reached 268.9 bars, having broken the former record of remarkable Russian RD-180" — Musk wrote. RD-180 — the Russian liquid rocket engine developed by NPO Energomash.
