The Japanese Aero Engines Corporation is a consortium of large Japanese companies (Kawasaki Heavy Industries, Ishikawajima-Harima Heavy Industries, Mitsubishi Heavy Industries) formed, in the late 1970s, as a partner to Rolls-Royce, originally to help develop the 20000 lbf RJ500 civil turbofan.

Although two prototype engines were built and ground tested, the RJ500 project was cancelled when Boeing rejected the engine, in favour of the CFM56-3, for the 737-300.

Around 1982, attention focused on developing a more advanced engine in the 25000lbf thrust class for the 150 seater market. Pratt & Whitney, MTU and FiatAvio joined the consortium, by then named International Aero Engines, shortly afterwards. The V in V2500 denotes the five original partners, whilst 2500 symbolizes the original thrust level of 25000 lbf. FiatAvio later withdrew from the V2500 consortium.
