As per some estimates, the IN should have three CBGs to dominate the Indian Ocean Rim. Therefore, how many subs and how many freewheeling with SLBMs off China?
the 30 yr sub building plan called for construction of 25 subs, 20 conventional and 5 nuclear.
the split between SSBN and SSNs was not specified.
although, IMHO it is time to increase the share of nuke subs, a total of 30 in total with
5 SSBNs, 10 SSNs and 15 SSKs seems better for the task.
the three AC envisaged 2 active at most times, that would mean 2X2 =4 SSN screens at any point of time. the rest can be away ideally tailing enemy SSBNs.
also, at some point of time we will definitely have the LPD class ships as mini CBGs mainly for defensive purposes or for shore based landings.
our backwaters (BoB and portions of IOR and Arabian Sea) can be sanitised with a combo of SSKs and MPAs.
