The main application for such an engine, the GP7100, was originally for the Boeing 747-500/600X projects, before these were cancelled due to lack of demand from airlines.

Instead, the GP7000 has been re-optimized for use on the Airbus A380 superjumbo. In that market it is competing with the Rolls-Royce Trent 900, the launch engine for the aircraft. The two EA variants are the GP7270 and the GP7277.

On September 30, 2017, an Engine Alliance GP7270 engine suffered from an uncontained failure during a passenger flight.[3] [4]
