The Irkut company, which includes the Yakovlev OKB, independently began work on it in 2007. Participation in the project and took the Ilyushin Design Bureau, which was engaged in designing the wing and pylons for engines. However, in the 2008, IL left the project. In the same year began full state funding.
For the future liner, engineers created a wing made of composite materials. For this, a special plant would be built in the Russian Federation. At that time, the only aircraft that had such a wing was the American Boeing-787.
In 2012, Irkut signed a contract with Pratt & Whitney for the supply of engines for the future airliner. At the same time, the Russian engine PD-14 was being developed in parallel, tests of which continue today.
