The Rocketdyne F-1 Engine (Saturn-V Engines Shown)

The Rocketdyne-Developed F-1 engine is the most powerful Single-Nozzle Liquid-Fueled rocket engine ever flown. The M-1 Rocket Engine was designed to have more thrust, but it was only tested in the component level. The F-1 was a Liquid-Fueled rocket motor, using RP-1 (Kerosene) as a fuel, and using Liquid Oxygen (LOX) as the oxidizer (Kerolox). A turbopump was used to inject the oxygen and fuel into the combustion chamber. (Source: 'Wikipedia')
