Serial production of MS-21 passenger airplanes will not start in 2024, as previously expected, Rostec CEO Sergey Chemezov said. According to him, the production will most likely be postponed to 2025 or maybe even 2026. In late 2023, at a meeting with Russian President Vladimir Putin, the head of Rostec said that 18 MS-21 airplanes were in various stages of readiness. He then predicted that the manufacturer would mass produce and deliver six airplanes to Aeroflot in 2024.
