The F-1, one of the most powerful rocket engines ever built, was used in the first stage of the Saturn V launch vehicle that took astronauts to the Moon in the Project Apollo program. The first stage of the Saturn V was fitted with five F-1's, which provided a total lift-off thrust of 7.5 million pounds. The fully-fueled Saturn V weighed 6.1 million pounds. The F-1 used RP-1, a type of kerosene, and liquid oxygen as the propellants. The engine shown here was transferred to the NASM in 1976 by its manufacturer, Rocketdyne.
