This object is on display in the Apollo to the Moon exhibition at the National Air and Space Museum in Washington, DC.

Collection Item Summary:

The F-1 engine, with 1.5 million pounds of thrust, was the powerplant for the first stage of the 363-foot long Saturn V launch vehicle that took the first astronauts to the Moon for six successful landing missions between 1969 and 1972 in the Project Apollo program. 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. This engine was constructed in 1963 by the Rocketdyne Division of Rockwell International and underwent four start tests, totaling 192.6 seconds. The engine was donated to the Smithsonian in 1970 by the NASA Marshall Space Flight Center.
