Let TEDBF happen first. And if it's better than Gripen, Mig-35, F16, F18, Su35, F15 on offer, then allow it in the competition or eliminate/disregard it with the others.
It's practically impossible. TEDBF requirements have not even been finalized yet whereas the IAF will want a "proven" airframe at the minimum by 2027 or so for evaluations, given a 2025 tender start. And by the time ORCA makes first flight, we could very well have signed MRFA.
Anyhow, TEDBF is being designed for 2035+, and it will achieve maturity only around 2040, which will then meet IAF's MRFA standards for evaluations, ie, a proven airframe. So ORCA is definitely not in contention with MRFA.
But why buy ORCA when we can buy AMCA?
I am not aware of any such policy. Do guide me where can I read upon this policy.
The fact that there isn't a white paper is proof enough. The govt has written white papers, but none have been formalized, never mind released to the public. Instead the forces themselves publicly provide their strategies and doctrines unilaterally.
Everybody knows what we want for now, maintaining territorial integrity and becoming the net security provider in the IOR. And our military is already focused on that, as publicly revealed by them. But what is private is what we are going to do beyond that. If there's a requirement to establish capabilities that will help us invade the ME or SEA, why the frig are they going to tell you that?
In simple terms, our objectives are offensive capabilities against Pakistan, offensive-defense capabilities against China and net security provider for the IOR. There, that's your white paper.
Once we start creating expeditionary capabilities via a marine corps, supercarriers, LHDs, strategic bombers etc, we will have to make our intentions clear. So until then a formal white paper isn't necessary.
