The fifth-generation Su-57 fighters, along with the Su-35S, underwent rigorous testing, including a full cycle of factory evaluations and operational tests conducted by pilots from the Russian Ministry of Defense. After successfully passing these assessments, the aircraft were transferred to their designated base.

Vladimir Artyakov, First Deputy Director General of Rostec State Corporation, highlighted the exceptional performance of the newly delivered aircraft: "The aircraft handed over to the troops are distinguished by their superior flight and technical capabilities, which have been well received by our pilots. Additional Su-57 units are currently at various stages of production, with Su-35S models also nearing completion."

As part of UAC's ongoing modernization efforts, the production facilities where these fighters are manufactured are being upgraded. Recent construction and installation work has been completed at the flight test station, and expansion of the serial production of the Su-57 is underway. A new facility dedicated to testing systems for these fifth-generation aircraft is also under construction.

The Su-57 is a fifth-generation multirole fighter developed by the Russian manufacturer Sukhoi. Its first flight took place in January 2010, and it officially entered service on December 25, 2020. With a unit cost of $50 million, this stealth fighter is notable for its ability to perform a wide range of missions, including air strikes, air superiority, and reconnaissance missions. Around twenty units have been built, including four prototypes. The Su-57 is powered by two AL-41F1 engines, which will eventually be replaced by more powerful Izdeliye 30 engines, expected to generate a thrust of 170 kN, though currently rated at 158 kN.

The Su-57 is an impressive aircraft in terms of its size: it has a length of 19.70 meters, a wingspan of 14 meters, and a height of 4.80 meters, with an empty weight of 18,500 kg and a maximum weight of 37,000 kg. Its performance matches its ambitions. The aircraft can reach a maximum speed of 2,600 km/h (Mach 2.45) and climb to an altitude of 20,000 meters. It has an autonomy of 5.3 hours, with a combat radius of 1,800 km, giving it significant strategic reach. The Su-57 can carry a variety of armaments, including an internal 30mm cannon and internal bays capable of carrying multiple air-to-air or air-to-ground missiles. Its six external pylons under the wings also provide it with nuclear capabilities. The avionics suite of the Su-57 includes the latest-generation Sh121 AESA radar, enhancing its detection and engagement capabilities.

The Su-35S, also built by Sukhoi, is a modernized and improved version of the Su-27. Designed as a multirole fighter, it has been in service with the Russian Air Force since 2012. This fighter made its first flight in February 2008. Around 135 units have been built, with some losses over the years. The Su-35S is powered by two NPO Saturn 117S engines, which are twin-turbofan engines with afterburners and thrust vectoring, each capable of delivering 130 kN of thrust.

The Su-35S is a larger aircraft than the Su-57, with a wingspan of 15.3 meters, a length of 21.9 meters, and a height of 6.4 meters. Its empty weight is 17,000 kg, and it can reach a maximum weight of 35,800 kg. In terms of performance, this aircraft can reach a speed of 2,500 km/h (Mach 2.35) at high altitude and climb to a ceiling of 19,000 meters. With a combat radius of 3,600 km at altitude, the Su-35S has a much greater range than the Su-57, although it is slightly slower. This aircraft is designed to excel in air superiority missions and precision strikes, and it is renowned for its exceptional maneuverability thanks to its thrust-vectoring engines.

UAC CEO Yuri Slyusar emphasized the growing importance of these fighters: "The number of fifth-generation fighters in the Russian Aerospace Forces is steadily increasing each year. The Su-57 is currently the most advanced frontline combat aircraft in Russia, representing the pinnacle of modern military aviation."
