There is not much one can do with a third and fourth generation aircraft even if one detects a missile flying towards you with Mach 14 speed loaded with several precise guidance systems.It's no point in getting into an arms race with India, they can clearly outspend us in that department. Only solution is to develop something better locally. Which I don't know if we are capable of or have the budget for development.
Basically there isn't much we can do, other than train our pilots in better SAM detection and avoidance.
S-400 shall severely undermine our air power and shall shift the balance of power to India. S-400 is a global threat for America and NATO as well and I am sure they must have thought of some antidote for it. America and Israel have successfully evaded S-300s in Syria so the only practical option left for us would be to take assistance from US and NATO countries. On the other hand , acquiring a stealth fifth generation fighter should be our preference.
