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 Technologies
After some reorganization, ATI operated with three segments: Aerospace and Electronics, Specialty Metals, and Consumer Products. The former Teledyne high-technology companies were mainly in the A&E Segment, led by Robert Mehrabian. ATI eventually decided to spin off the segments into independent entities, and on November 29, 1999, Teledyne Technologies Incorporated, Allegheny Technologies Incorporated, and Water Pik Technologies, Inc., were formed.
