How The V-2 Rocket Launched America's Space Race
It's well known that after World War II the rocket scientists involved with the V-2 were recruited to the the US under Project Paperclip, but the exact evolution of the Model 39 rocket engine used on the V-2 into the engines used by US rockets is less well known.
The engine was far from perfect and US engineers tore them apart and designed improvements, ultimately the majority of US launch vehicles had engines with some heritage from the V-2.
A lot of relevant information comes from the Engine History Website
