About SU-57.

Well, it looks like the Izdelie-30 (a new engine for Su-57) IS in serial production and this year batch and all 22 Su-57s for the next year will be equipped with this brand new engine. But this is not what struck me--it was clear that the new engine was ready for some time--what struck me, and it doesn't seem to be a rumor, Su-57 starting from the next year will be equipped with Radiophotonics (Radio-optical--ROFAR) radar. This changes everything because ROFAR allows to detect, identify and track any targets at a range of 500+ kilometers. Make your own conclusions on that. Russia (KRET) did create first fully functional ROFAR already in 2020.
