The Russian Air Force has present received six serially produced Su-57 5th procreation combatant jets, the archetypal of which was delivered successful December 2020, with accumulation lines astatine the Komsomolsk-on-Amur craft works successful the country’s Far East continuing to expand to accommodate a larger capacity. Despite the fleet’s tiny size, the combatant has been deployed for combat successful the past including prototypes launching cruise missiles astatine Islamist insurgent positions successful Syria, and much precocious serial accumulation models deploying a scope of standoff missiles for strike and air defence suppression missions successful Ukraine. Although this has made it the first fighter of its procreation to usage specified standoff weapons successful combat, the Su-57 programme nevertheless remains acold down schedule. Its introduction into work was initially scheduled for 2015, portion a fleet size of 50 fighters was antecedently expected to beryllium reached successful 2020 alongside further accumulation for export. The fleet was past scheduled to scope 200 craft by 2025.
The opposition betwixt anterior plans for the Su-57's induction and those of contiguous are significant, with the fleet scheduled to scope 22 fighters by the extremity of 2024 and 76 fighters by the extremity of 2027 indicating it volition person an mean of 18 fighters per twelvemonth from 2024-2027. This would correspond a higher complaint of accumulation than immoderate existing Russian fighter, though it could beryllium partially fulfilled by craft produced earlier which whitethorn instrumentality longer to beryllium made acceptable for service. Such a accumulation complaint could facilitate deliveries to the Air Force of 14-18 fighters per twelvemonth aft 2027 depending connected export demand, with exports successful the 2030s expected to beryllium considerable. At existent estimates the Russian Air Force’s Su-57 fleet volition scope 50 fighters lone sometime successful 2026. Such delays would beryllium acold from unprecedented for a 5th procreation program, with the American F-22 and F-35 suffering from akin delays periods. It volition nevertheless opposition to the Chinese J-20 program which was made acceptable somewhat earlier than expected and archetypal delivered to the Air Force successful 2016. It besides falls acold abbreviated of expectations for the Soviet Air Force which was expected to tract astir 50 MiG 1.42 5th procreation fighters by 2005 if not earlier.
A superior contented stemming from delays to the Su-57 programme is that by the clip it is fielded successful meaningful numbers, China and the United States are expected to already person begun fielding sixth procreation fighters that are expected to go operational astir 2030. A secondary contented is that overmuch of the Russian combatant fleet inherited from the Soviet Union comprised of MiG-29s and Su-27s, has already been replaced by Su-35, Su-30SM/SM2 and Su-30M2 fighters - each of them enhanced Su-27 derivatives - leaving overmuch little country successful the fleet for caller Su-57 units. Serving arsenic a nonstop successor to the Soviet Su-27 4th procreation heavyweight aerial superiority combatant which archetypal entered work successful 1985, the Su-57 and its derivatives are expected to spot a likewise agelong accumulation tally and to integrate a wide scope of sixth procreation technologies to stay applicable arsenic caller American and Chinese programs pb the field.
