Rocketdyne engines

Rocket engines for aerospace and weapons developed and manufactured by Rocketdyne (1955-2005), Pratt & Whitney Rocketdyne (2005-2013), and Aerojet Rocketdyne (2013-present).

The Rocketdyne Division was part of: North American Aviation (1955-1967); North American Rockwell (1967-1973); Rockwell International (1967-1996); and Boeing (1996-2005); then as Pratt & Whitney Rocketdyne with Pratt & Whitney of United Technologies Corporation (2005-2013); and as Aerojet Rocketdyne of GenCorp (2013-present).
Main rocket engine production was done at the large Rocketdyne facility located in Canoga Park (1955-2013), in the western San Fernando Valley of Los Angeles, Southern California.
The large Santa Susana Field Laboratory (SSFL), was opened in 1947 by North American Aviation in the nearby Simi Hills, to land-test forerunner and Rocketdyne engines. Closed since 2006, it is a major state "Superfund" site for the cleanup of chemicals and radionuclides in soil and water, by Boeing, NASA, and DOE.
