| has gloss | eng: The S-IB stage was an eight engine booster 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, which contained LOX. The four outboard engines gimballed, meaning they could be steered to properly guide the rocket. This required a few more engine components. |
