Rocketdyne

Rocketdyne was an American rocket engine design and production company headquartered at Canoga Park, in the San Fernando Valley of Los Angeles. North American Aviation made it a separate division in 1955, building on its work on the Navaho missile engine and the V-2 derived A series engines used on the Redstone. It passed to Rockwell International in 1967, to Boeing in 1996 and to Pratt & Whitney in 2005, and in 2013 it was merged with Aerojet to form Aerojet Rocketdyne. Its engines include the Atlas and Thor engines, the H-1, the F-1 and J-2 of the Saturn V, and the RS-25 Space Shuttle Main Engine. By 1965 it built the vast majority of United States rocket engines, apart from those of the Titan.
