Army can't do much without air superiority. IAF at present is fine to deal with pakis but not so much with China.India may have to focus massively on its Army. I think very large very expensive fighter purchases may not happen as desired by many enthusiasts. Ultimately Army will be critical in large scale war; far more than Air Force.
Shortcuts are necessary. India is negotiating for 21 Mig-29 with Russia. IAF should look for other deals where price is within budget.
Sometimes second hand equipment is good too. And weapons matter as much as the firing platform as proved on Feb 27. My feeling is that even an old F-15 is better than Su-30 despite its large RCS; due to better offensive capability.
Su 30 MKI might have been a good aircraft for the past , but not so much in the present. Outdated radar , massive radar cross section , lack of countermeasures. India needs the super sukhoi upgrade at all costs, and believe me Russia is gonna make India bleed money for it.
