Russian Defence Ministry planned to conclude a second contract for 13 more aircraft in 2020. However, on 15 May 2019, Russian President Vladimir Putin announced that 76 aircraft will be purchased and delivered to the Air Force by 2028. This came after the price of the Su-57 and equipment was reduced by 20%. The contract for the 76 aircraft was formally signed on 27 June 2019 at the International Military-Technical Forum «ARMY-2019». The same month, General Director of Tactical Missiles Corporation (KRTV) Boris Obnosov reported, a contract for serial production of ammunition for Su-57 fighters was signed, and is being inducted.
