Rocketdyne is a former American aerospace company that was a subsidiary of North American Aviation and later Rockwell International. Founded in 1955, Rocketdyne was instrumental in the development of liquid-propellant rocket engines for various United States space programs. Its most famous engine is the F-1, which powered the first stage of the Saturn V rocket used in the Apollo missions to the Moon. Other notable engines include the J-2, used on the Saturn V's second and third stages, and the RS-25, originally developed for the Space Shuttle.

Throughout its history, Rocketdyne developed a wide range of rocket engines for military, scientific, and commercial applications. The company's engines were used in numerous rockets, including the Atlas, Thor, and Delta families. Rocketdyne also played a significant role in missile programs, developing engines for intercontinental ballistic missiles. In 2005, the company was acquired by Pratt & Whitney Rocketdyne, which was later purchased by Aerojet and became Aerojet Rocketdyne. The legacy of Rocketdyne continues through its groundbreaking engine designs that have propelled humanity's exploration of space.
