Irkut MS-21 (“Trunk Airplane of the XXI Century”) is a Russian project for the near-medium-medium mid-body [to clarify] a passenger airplane. The solemn ceremony of rolling out the new MS-21 aircraft was held at the Irkutsk Aviation Plant on June 8, 2016 [8]. The first flight took place on May 28, 2017 [2]. The start of series production is scheduled for 2017 [9]. It is assumed that the main competition for the Irkut MS-21 aircraft is the Chinese COMAC C919 aircraft, but at the same time, the MS-21 aspires to the same commercial niche as the Boeing-737 MAX and the Airbus A320neo
