1) MRCA2.0 is never going to happen, and option of 36 rafales is also now over.
2) Induction 26 F18's for navy available within few years will help in having some technological edge in some or the way through various weaponaries and configurations it will carry.
3) 50 sukhois should be considered, and I dont know why 21 Mig 29's have been put on backburner despite them proving to be capable design and thrust wise in high latitude conditions. Sukhois dont give us any edge technology wise, but in future after embedding our on technologies, we can gain some edge back and then some modifications like dedicated for long range strike, dedicated bomb trucks, ew configurations can also be used.
4) Continuous and very rapid upgradation of Indian fighters like Mig 29 and Su30mki's by India with Indian systems in a dedicated manner, we are doing it in some manner.
