Pratt & Whitney Rocketdyne
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. History

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. The sale was completed in June 2013, when the company was merged with Aerojet to form Aerojet Rocketdyne. Products
