I am very worried about this part. No fighter in the world meets its design specifications and design weight is always exceeded 90% of projects. So without the appropriate engine there will be performance deficiencies.
There is a better option - the GE F110 that starts at 125 kN and goes up to 144 kN.
It is also license assembled by South Korea and Turkey, so assembling at Koraput wont be a challenge.
The best part? Its offered as a part of the US F-21 proposal to India. Though I would gladly take the engine and leave the close to obsolete plane
First we need ascertain if the said thing is accurate or not. I dont think it is, as of now.
Second, please don't just look at the Thrust value. If it was possible to make 5th Gen Fighter using F110, the Americans would have happily used that one itself instead of spending tens of billions of USD in development of F119. The Russians would have stopped at Al41F, without having to go for I-30. F110 is longer, much larger in diameter, and heavier than F414. Though its comparable in these parameter with F119, but what this means is the airframe needed to accomodate these two large engines could not be mere 12T empty weight. It would have to be much larger. And then F110 would be grossly inadequate for that large airframe. That airframe would never supercruise even in its dreams. It would be one hell of a short legged aircraft due to excessive fuel comsuption.
Given the IAF requirements, the AMCA is expected to replace the Su-30MKI 2030-35 onward. So the design will definitely need to grow beyond 12T empty weight.
The Su-30MKI filled the gap of Canberra that was a light bomber. No 106 that last flew Canberra now flies Su-30MKI.
Supercruise isnt an essential requirement. However, the engine powers the F-15 Eagle and heavier versions of the F-16 with reasonable payload and range. The F110 is derived from F101 whose technology went into CFM engines powering highly economical civil airliners.
