The capability is also another factor. We're assuming the Tejas is a perfectly competent Mig-21 for the modern era. Those are some big shoes to fill.
Yeah, people forget that mig-21 originally didn't become known as shitcan. It became known for being one of the earliest mach 2 jets, screwing starfighters, thunderchiefs and phantoms, and taking more than a decade for US to truly solve.
Which also conveniently happened to cost nothing.
In this way, modern mig-21, at the very least, will be VLO...
IAF currently refuses to use the Tejas in any (and so far, every) single engagement despite the Tejas in original and Mk1 form are available for IAF use for some time and are allegedly operational.
To be fair, there was only 1, and they were very far from it. Tejas mk.1a are very short ranged and explicitly meant as a local asset, rather than deployable/committable reserve.
This system is partially broken nowadays (India just doesn't have enough light fighter squadrons), but next 1a squadrons will go to the northwestern sector.
Yes, and now they need to go back and do it properly asap. They will never be able to catch up at this rate. Skipping steps doesn't work. And everyone is teaching them improperly on purpose, and laughing. The situation is hilarious. India's desperation for a tech transfer is so obvious, and their position is so weak they cannot secure any actual support. The French are just laughing to the bank.
LCA is "almost there", and it's their best shot. Plus modern fighting environment is complicated enough as to let non-stealth jets remain relevant, provided their equipment and weapons keep up.
The LC problem was of course that Indians severely overestimated themselves (FBW, highly unstable jet), and it took them so long, that a far more modest approach(JF-17) brought more results, earlier, for much less.
Yes, JF-17 didn't really promise independence, but it brought in large, modern air force to a nation that otherwise couldn't afford one, control over aircraft, and a substantial, healthy supplier ecosystem.
