Disadvantages of the Russian Su-57 fighter

An air force expert from the Royal United Nations Institute for Defense Studies (London) named the shortcomings

Russian Su-57 fighter. He believes that there are a lot of unresolved problems with the plane.

The expert's opinion is published by Voennoye Obozreniye. He writes that the development program for the Russian Su-57 involved the creation of a comparable F-22 fighter. As a result, the aircraft turned out to be "a highly modified derivative of the Flanker airframe (approx. Su-27), the shape of which minimizes the frontal X-range (approx. Radar cross section), while maintaining super-maneuverability."

However, the expert doubts the stealth of the Su-57.He believes that due to some elements the plane can be detected. The reason for their appearance could be budgetary restrictions and Russia's relative inexperience in designing stealth aircraft.

Also, according to experts, financial restrictions could also affect the Su-57 sensors.

The expert came to the conclusion that the Russian military toBy the end of the 2020s, significantly less than 100 Su-57s will be in operation, and the likelihood that the aircraft's sensors, avionics and engines will be mature is low.
