Pratt & Whitney Rocketdyne (PWR) was an American company that designed and produced rocket engines that use liquid propellants. It was a division of Pratt & Whitney, a fully owned subsidiary of United Technologies Corporation. It was headquartered in Canoga Park, Los Angeles, California. In 2013, the company was sold to GenCorp, becoming part of Aerojet Rocketdyne.


Pratt & Whitney Rocketdyne was formed in 2005 when Pratt & Whitney Space Propulsion and Boeing Rocketdyne Propulsion & Power were merged, following the latter's acquisition from Boeing by United Technologies Corporation. Boeing retained the 2,800 acre Rocketdyne Santa Susana Field Laboratory property above Canoga Park while a majority of the engineering and design continued to be carried out at the Pratt & Whitney Space Propulsion facility located on Beeline Highway outside West Palm Beach, Florida.

In July 2012, United Technologies Corporation agreed to sell Pratt & Whitney Rocketdyne to GenCorp, which also owns rocket engine producer Aerojet.[1][2][3] The sale was completed in June 2013, when the company was merged with Aerojet to form Aerojet Rocketdyne.[4]
