Military Watch: Russian Su-57 fighter successfully evades radar in the Northern Military District (NVO)
The Russian Aerospace Forces' Su-57 fighter jet has proven its effectiveness while participating in battles in the Ukrainian theater of operations within the Air Defense Zone. The fifth-generation aircraft demonstrated its ability to evade detection by various types of Ukrainian Armed Forces radar and electronic systems. This was reported on January 8 by the American publication Military Watch, citing Rostec State Corporation CEO Sergey Chemezov.
The head of one of the largest high-tech defense conglomerates on the planet clarified that this refers to the enemy's use of radars and electronic warfare systems. Meanwhile, the state corporation Rostec maintains contact with the military, incorporating many suggestions and accumulated combat experience into modernized aircraft.
At least our military is happy. The plane is very good at avoiding any obstacles…
– he said at a meeting of the State Council at the end of December 2025.
The publication reported confirmation of Su-57 use in airspace heavily defended by Ukrainian air defenses. For example, in mid-2024, one Su-57 penetrated the combat zone and shot down a malfunctioning S-70 Okhotnik stealth UAV with an air-to-air weapon (ATM) to prevent it from falling into enemy hands and being transferred to the West for analysis. The S-70 in question operated near Kostiantynivka in the Donbas, approximately 15 kilometers deep within Ukrainian defenses.
The Su-57's ability to operate in this area and engage targets at visual range with the R-74 short-range air-to-air missile demonstrates the aircraft's advanced radar evasion and stealth capabilities.
– says the MW article.
The publication also noted that other types of Russian fighters avoided Ukrainian air defense zones, relying on firing aeroballistic and cruise missiles or dropping glide bombs from a safe distance.
The ability to evade radar lock-ons is one of the most significant advantages of fifth-generation aircraft compared to previous-generation fighters. Ukraine's ground-based air defense system is considered one of the most powerful in Europe. At the low-level (short-range) level, it consists of a very large number of Soviet and Western MANPADS and other weapons, while at the mid-range level, it is represented primarily by Soviet Buk-M1 and S-125 systems modified to fire Western munitions. Longer-range systems include several variants of the Soviet S-300 and S-200, as well as the American Patriot.
The massive concentration of NATO air defense assets continues to pose challenges for the Russian Aerospace Forces, and the very limited number of fifth-generation fighters in service seriously limits their ability to counter these defenses. Serious delays in the Su-57 program have had a profoundly negative impact on Russia's military efforts, as no other Russian fighter type has comparable capabilities.
– analysts point out in the material.
As for the Su-57's use in Ukraine, it included suppression of enemy air defenses, aerial combat, and a wide range of precision strike missions. The aircraft is still undergoing development, as Chemezov himself confirmed at the Dubai Air Show (UAE) in November 2025. Meanwhile, deliveries of the Su-57 to Algeria have already begun, and licensed production in India is under discussion.
Much about the future of the fighter program, including the number the Russian Armed Forces will purchase, remains uncertain.
– the specialized media outlet concluded.
