The F-1 engine, producing 1.5 million pounds of thrust, was the powerplant for the first stage of the giant 363-foot long Saturn V launch vehicle that took a dozen astronauts to the Moon in six lunar anding missions between 1969 and 1972 in the Project Apollo program. The first stage was fitted with five F-1's for 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 turbopump for the engine pumped in the propellants at 42,500 gallons per minute. The F-1 was developed and built by Rocketdyne, Division of the Rocketwell International Corp. The engine was transferred to the Smithsonian from the NASA Marshall Space Flight Center in 1975.
