The Japanese Aero Engines Corporation is a consortium of large Japanese companies (Kawasaki Heavy Industries, Ishikawajima-Harima Heavy Industries, Mitsubishi Heavy Industries) that was established in 1981.
In the late 1970s, they had partnered with Rolls-Royce, originally to help develop the 20000 lbf RJ500 civil turbofan. (Needs citation)
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.
