5 J-2 Engines
2?
There were eleven main engines on the Saturn V. Five on the first stage, five on the second stage and one on the third stage. This does not count the engine on the lunar lander. How do I know? I worked as an Aerospace Engineer on the first stage of the Saturn V during Apollo. My partner and I were the ONLY two women working on the Saturn V.

Answer The Space Shuttle is a rocket. By definition, a Rocket is a vehicle that burns gas that it carries with it. Where as, a jet airplane burns the oxygen from the air and is not a rocket. The Rocket when it is launched has a liquid fuel rocket engines at the back end of it. It also has two long, solid fuel rocket engines that separate after launch. But the space shuttle is pulled by a rocket.
The two white Solid Rocket boosters fall back into the sea and are re-used. The main engines are on the shuttle itself which of course is used many times.
3 mainly but it can be more or less depending on the rocket
The two main types of rocket engines are Solid fuel rocket engines and Liquid fuel rocket engines.
Because it's moving a smaller mass. The first stage of the rocket has to move the whole vehicle. By the time you're ready to fly on the third-stage engines, you've burned up the fuel in the first two stages and separated from them.
That's a rocket with two stages- when the first stage (or section) runs out of fuel, it separates from the top half (second stage) and falls away, leaving that second stage to fire up, and drive the rocket higher.

There are two main types of rocket engines: Solid fuel and liquid fuel. Liquid fuel rocket engines are usually considered significantly better than solid propulsion units, however, they are also significantly more expensive.

five, three main and two solid rocket boosters
