The H-1 liquid-fuel rocket engine was the first stage power plant for the Saturn 1 and Saturn 1B launch vehicles, the precursors to the Saturn V, the rocket that propelled astronauts to the Moon in the Apollo program. The 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 as fuel. The Saturn 1 first flew in 1961 while the last Saturn 1B was flown in 1975 for the Apollo-Soyuz Test Project. The Rocketdyne Division of Rockwell International donated this engineering model to the Smithsonian Institution in 1976.
