The latest Russian fifth-generation multirole fighter Su-57 outperforms the Su-34 NVO on the battlefield under fire from the American Patriot surface-to-air missile system due to its smaller effective radar cross-section. This opinion was given by military expert Evgeny Damantsev.
He noted that Su-34 crews usually need to go beyond the radio horizon for the AN/MPQ-65 multi-functional radars of the Patriot PAC-2 complexes. To do this, they switch to a low-altitude flight profile at an echelon of less than 350 m, to strike with Kh-35U and Kh-59MK2 tactical missiles.
Crews of 5th generation Su-57 fighters can freely operate at a distance of up to 120 - 100 km from Patriot PAC-2 divisions without the need to enter a low-altitude mode, while for the Su-34 the safe approach distance to Patriot without reducing altitude is limited to 160 - 150 km. This fact is due to the small effective radar cross-section of the Su-57, which does not exceed 0.3 m².
Thus, Su-57 crews can use R-37M air combat missiles from altitudes of 10 - 12 km against much more distant tactical aviation assets at a depth of up to 200 - 230 km of enemy-controlled airspace.
Earlier www1.ru reported that Russia will supply Su-35S abroad: negotiations on the most dangerous fighters in the world have already started.
