Since its inaugural run in 1991, the AE3007 has achieved remarkable success with over 3,400 units produced. Its versatility spans from powering the high-performance Cessna Citation X to enabling cutting-edge unmanned aerial vehicles like the Boeing MQ-25 Stingray and Northrop Grumman’s advanced drones.
History and Development of the AE3007
The AE3007’s story began in 1988 through a strategic partnership between the Allison Engine Company and Rolls-Royce plc. Initially conceived as the RB580, a 33 kN (7,400 lbf) engine for the Short Brothers FJX regional jet, the project combined the robust T406 core with Rolls-Royce’s advanced low-pressure spool technology.
Despite Rolls-Royce’s withdrawal in late 1989, Allison persevered, refining the design until its successful debut in 1991. This determination marked the beginning of a new chapter in turbofan technology.
