Apparently the Izdeliye-30 still hasn't begun testing on the Su-57 . I read reports it was to happen towards the last Qtr last yr . Add 3-4 yrs of testing & certification after that . That's already 2027. Add negotiations & contract signing to it which'd be 3 yrs & we're in 2030 post which 3 yrs for delivery of the first FA which makes it 2033 .With new engines, this plane is just going to be super awesome. Stealth, supercruise, supermaneuverabilty, AI, MUM-T, ability to defeat both RF and IIR missiles. 360° IR sensors and in future distributed radar sensors too.
Cheek mounted AESA arrays which means it can shoot and crank with impunity while the enemy just will have to break away and run or die.
Dropping out of FGFA was our biggest mistake. IAF just wanted Rafale at that time. Now everyone realizes what a big mistake it was. Even 2-3 squadrons of Su-57M will provide IAF with teeth to seriously hurt PLAAF and J-20.
In any case we'd receive AMCA Mk-1 by 2032-33 & Mk-2 by 2037- 38 give or take a couple of yrs. So what's the point ?
Frankly I don't see it coming when we want it to which was one of the other reasons we dropped out of the project. As it is we're running out of time .
