Correction: It seems instead of shtil barak 8 is prefered choice for mlu of delhi class by navy.Navy intends to standardize barak 8 accross all its capital ships that can work together with CEC capability.So barak 8 will go on board both carriers(already on vicky),plus all kolkata,vizag,p17a shops.Shivalik and delhi class also to get it, subject to problems with integration and cost.22 ships in total planned.
Talwars will remain with shtil and are meant for workhorse duty and affordable number increment to the fleet.Expected indian navy fleet by 2030-
2 carriers
10 destroyers(3 Delhi upg..3 kolkata..4 vizag..with next gen destroyer finishing construction)
23 Frigates(10 talwars,3 brahmaputra upg,3 shivalik, 7 p17a)
20 ASW corvettes(4 kamorta..16 shallow water asw craft)
7 multi role corvete(ngc)
10 missile corvettes( 6 ngmv + 4 kora)
Plus OPV, amphibious ships, support vessels.
We can expect 4-6 SSBN s however.2 akula ssn with indian model beginning construction.
However number of ssks to dip badly even with 6 scorpenes,maybe half a dozen upgraded kilos will be operational, shishumar 209 class retired.Maybe 3-4 of the p75I would be operational.Cant see more than 15-16 ssk which is a danger for us.
Which is why we should add 3 scorpenes or make an off the shelf purchase of upgraded 636 kilos which are cheap and effective.
