Of greatest interest here isengine. It is a combination of a ramjet engine, a hypersonic ramjet engine (scramjet) and a rocket engine. As the rocket accelerates, the engine switches from one mode to another.

Such an engine has a number of advantages, the main one beingwhich is that it doesn't need to carry as much pressurized oxygen as a clean rocket. It can collect oxygen from the air like a normal jet engine. This ultimately allows you to carry more fuel or a larger payload. In addition, Feitian-1 can run on kerosene-based aviation fuel.

It is claimed that the engine is capable of accelerating the rocket to a speed of over Mach 5.
