I did not say US will transfer sensitive military tech to India. No country will. But what the US gives is business opportunities and training to best manufacturing practices of high tech weapons or their subsystems.
Did Russia partially construct any of the fuselage or subsystems of any of the attack helicopters it uses in its service (Russian Army) or it sells to its clients?
I understand some Super Hornet subsystems are already being built in India even if India haven't ordered any Super Hornet yet.
Amd in commercial aviation India is supplying a lot of subsystems and parts to American companies.
In all these activities even if no sensitive tech is transferred to India but on the very least India is already benefiting from revenues and quality control knowledge.
Imagine if Lockheed Martin relocates its F-16 assembly plant to India. Again, even if no senditive tech is transferred to it by LM snd its subcontractors but the business potential and production knowledge potential is considerable. There will still be F-16 orders in the coming 15 or more years since not all countries are cleared or cam afford to buy F-35. India can also exert leverage on Pakistani F-16 fleet. Plus, F-16V is no slouch. It is infinitely better than Mig-29 or Mig-35 and will give Su-35 a good fight.
Again, has Russia or even France given this kind of industrisl benefits to India?
