Su30 with AESA jamming pod (already developed) is essential otherwise J-20 and KAAN's geometrical stealth will outclass su30 anyday.
Maybe throw in some CATS warriors flying few km ahead.
Turkey gonna use kizilelma for combat teaming
i am more interested in india sticking to tried and tested aircraft under production within India like su30 and Tejas for example while developing the amca and Tejas mk2 for now as in the immediate future(next 10 years) the issue is numbers, not quality. also, we can induct the su30s and tejas with our own intermediate updates and new tech to at least make them competitive. the only issue is the potential high
NOs of Chinese fighters on our borders not the pakistanis who are mostly a spent force (it will be hard to maintain any good force nos of aircraft or any complex systems with the economy and demographic issues in the near,medium and longterm in pakistan).
We should also populate our border areas with cheaper and more readily manufacturable(as in available for manufacture by our own indigenous capability ) long range air defence systems in the s400 and buk styles. also rely on asymmetric solutions for the immediate term. while building and developing system as soon as possible like amca to mass produce in the future.
This is the most realistic option we have. of course the ideal would be amca and tejas mk2 getting rolled out soon and getting good orders by 2030.
