Design of the Rolls-Royce Avon began in the late 1940s with the first production model being delivered in 1950. The Avon was Rolls-Royce's first axial-flow jet and was developed to replace the Nene.
Initially designated the AJ.65 (axial jet, 6,500 lb thrust), the Avon went through several designations and is currently marketed as a stationary power source.
