Russian SU-57 aircraft have demonstrated high efficiency in the highly concentrated areas of Ukraine's air defense systems, writes Military Watch magazine.
"The Russian Air Force has shown great confidence in the Su-57 and has deployed fighters to carry out intensive combat operations on the territory of Ukraine in areas where the concentration of air defense systems is particularly high," the article says.
It is noted that the new AL-51F-1 engine, which is equipped with Su-57 aircraft, can provide them with the highest level of thrust among all fighters in service in the world.
