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.

All of these designs, like the V-2 that spawned them, burned ethanol, but other fuels had also been experimented with, including kerosene, diesel oil, paint thinner, JP-4, and JP-5 jet fuel. In January 1953 Rockedyne started their "REAP" program to convert these engines to a specific and well engineered kerosene fuel specifically for rocket engines, which became RP-1, officially specified in Military Specification MIL-R-25576 in 1954.
