Why not throw in some death star laser, tractor beams and Gundam also while you're loading it?Now in 2017 IN can logically go for Cruisers , at least 4 , with conventional diesel - electric propulsion ( for low installation & maintenance cost ). Equip them with S400 , Barrack 8 , Spyder & Akash QR SAM , CIWS , guttling guns , 32 BrahMos , 32 BrahMos II , 32 hypersonic Zircon anti-ship , Agni II , III & IV 8 each , 48 P - 700 Granit anti ship missile ( we are in MTCR NOW), 64 Dhanush( for land attack ) & space for Nirvoy Installation.For ASW RBU 6000 Smrech 2 & RBU 1000 Smerch 3 rocket pods .With them 4 main gun of 155 calibre & 16 nos of 76mm gun.
If we choose it to be close to 20000 ton then 8 F 35B & 6-8 ASW helicopter & 4 utility helicopter can be on board. Like 2 carrier battle group we can form to 2 cruiser battle group adding 3-4 submarine ,1 destroyer, 2-3 stealth frigate , 2 stealth corvettes , 1 amphibius assult ship & replanishment ships. The other 2 can be used to put an umbrella over carriers in combat situations.
Cruisers of given specs can bring hell upon any enemy. With the given fire power a single cruiser will be able to exterminate the entire PAK navy along with Karachi & Gwadar ports. For PLAN we would have 2 carrier battle group & 1 cruiser battle group free.
