"In the upgraded version of the fighter as part of the Megapolis research and development project, a completely upgraded cockpit with the most advanced avionics will be installed. In addition, the aircraft will be equipped with a second stage power unit. It is planned that mass production of the upgraded Su-57 will start from 2025," the source said.
