I never get why the Navy is so infatuation with CBGs,
A Carrier Battle group is useless unless it matches the fire power of the American CBG
If all you intend to do is set fire to Gwader and Karachi, then Vikramaditya and Vikrant along with their complement of Mig29Ks are enough
However for anything else like a confrontation with China, you need a much better CBG
A single 65000 Ton carrier along with its complement of 36 Fixed wing aircrafts and 8-10 Helis will cost 15 Billion USD
If the air wing comprises of Rafale M or F35C
It could be much cheaper if F/A18 is chosen
This money is better utilized in purchasing 12 Brand new Minesweepers, 100 NMRH, 6 additional Scorpenes and another 30 Mig29K for the navy
