This is the F-1 rocket engine used in the first stage of the Saturn V launch vehicle that took astronauts to the Moon in the Project Apollo program. Each F-1 produced 1.5 million pounds of thrust. The first stage of the Saturn V had 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 F-1's 2,500 pound turbopump pumped in the propellants at 42,500 gallons per minute. The engine was made by Rocketdyne, a Division of North American Rockwell Corp. Rocketdyne also made the J-2 engines used in the Saturn V's second and third stages. Donated to the Smithsonian by Rocketdyne in 1975.
