What does the Indian navy plan to protect that carrier with?
5.56mm
They have a number of 1980s era frigates and destroyers, but have been building new frigates and destroyers as escorts. They also have a number of Russian Kilo and German Type 209 subs, but those diesel electrics cannot keep up with carriers.
They have jut leased a newer Russian attack sub, and are building a second for purchase with options to buy the first one too. They are also involved in building their own first nuclear subs.
Firat ready this year, second early next, third 2014
(They already have 8 older DDGs, these will be the first with phased array radars.)
