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.
Rayleigh Rockets
The Rockets rode at the stadium until 1973 when it was announced that the stadium had been sold to developers and the Rockets would need to find a new home. Len Silver took the Rockets to Hoddesdon in Hertfordshire to start the 1974 season as the Rye House Rockets. The former site of Rayleigh Stadium is now a retail park.
