Rocketdyne
The Rocketdyne Division was founded by North American Aviation (NAA) in 1955, and was later part of Rockwell International (1967-1996) and Boeing (1996-2005). In 2005, the Rocketdyne Division was sold to United Technologies Corporation, becoming Pratt & Whitney Rocketdyne as part of Pratt & Whitney. In 2013, Pratt & Whitney Rocketdyne was sold to GenCorp, which merged it with Aerojet to form Aerojet Rocketdyne.
Teledyne Turbine Engines
After the 1999 sale of Teledyne Ryan Aeronautical to Northrop Grumman, and the subsequent spin-off of Teledyne Technologies Inc. by Allegheny Teledyne in November that year, Teledyne CAE was renamed Teledyne Turbine Engines. In the next decade, it was placed under Teledyne Continental Motors as its TCM Turbine Engines division.
