Rocket Engine, Liquid Fuel, H-1
This is the H-1 liquid-fuel rocket engine built by the Rocketdyne Division of Rockwell International, the first stage powerplant for the Saturn 1 and Saturn 1B launch vehicles that were precursors to the Saturn V that took men to the Moon in the Apollo program. Saturn 1 and Saturn 1B were each fitted with eight H-1 engines in their first stages.
The engine used RP-1 (kerosene) and liquid oxygen. The model shown here may be the second variation that produced 188,000 pounds of thrust. Saturn 1 first flew in 1961 while the last Saturn 1B was flown in 1975 for the low-Earth orbit Apollo-Soyuz Test Project. This engine was donated to the Smithsonian in 1970 by the NASA Marshall Space Flight Center.
