I am hoping for a combination of shtil-1 and Barak-2. If what they say about the range of barak-2 (70-80) km is true, then it would provide a decent air defence. Of course adding a few S-300 would be even better but might be wistful thinking.

If you have Barak 2 installed, adding Shtil 1 is just a waste of space and weight as the former missile would be superior to the latter in terms of range and – probably – guidance. Besides, I expect Barak 2 to be more compact and lighter than Shtil 1. Putting S-300 on this carrier makes no sense as this would take up even more space and weight, not just for the missile launchers but also for the Tombstone radar director(s). Instead of the Russian approach, which has carriers armed like a cruiser, India follows the ‘western pattern’ of carrier armament: light and purely for self-defense, much like a frigate. Medium and long range SAMs are then placed on escorting dedicated air defense destroyers/frigates
