S-IB

The S-IB stage was the first stage of the Saturn IB launch vehicle, which was used for Earth orbital missions. It was composed of nine propellant containers, eight fins, a thrust structure assembly, eight H-1 rocket engines, and many other components. The propellant containers consisted of eight Redstone tanks (four holding LOX and four holding RP-1) clustered around a Jupiter rocket tank containing LOX. The four outboard engines gimballed, meaning they could be steered to guide the rocket. This required a few more engine components.

H-1 engine

The H-1 engine is a thrust LOX/RP-1 engine, used alone in the first stages of some Delta rockets and the Jupiter rocket. It is derived from the Navaho missile, and was simplified and improved for S-IB use. It is used in clusters on all S-IB rocket stages. Later it would be uprated to of thrust. The H-1 preceded the F-1 engine, which was used on the Saturn V rocket.
