Rocketdyne was an American rocket engine design and production company headquartered in Canoga Park, in the western San Fernando Valley of suburban Los Angeles, in southern California.
Rocketdyne was founded as a division of North American Aviation in 1955 and was later part of Rockwell International from 1967 until 1996 and Boeing from 1996 to 2005. In 2005, Boeing sold the Rocketdyne division to United Technologies Corporation, becoming Pratt & Whitney Rocketdyne as part of Pratt & Whitney. In 2013, Rocketdyne was sold to GenCorp, Inc., which merged it with Aerojet to form Aerojet Rocketdyne. The space portion of Aerojet Rocketdyne will be spun off as a new company named "Rocketdyne" in the second half of 2026, following an acquisition from L3Harris by AE Industrial Partners.
