Weren't the first IN frigates to get SSMs the Talwar and Trishul, lifted from old Osas? Wasn't the Nilgiri the first indigenous warship to have Air-con too?
Looking at the good admiral's article,he has made his observations from the current cost factor,given the naval/defence budget as of now.I would enlarge upon his observations,as given currnt trends,the defence budget must be raised if we are to meet current and future challenges,especially the huge Chinese threat looming on the horizon in the IOR and its aggro on our borders.Pak being pumped up with "steroids" thanks to the asinine US remains the irritant factor to be added to the Chinese gameplan.
Therefore,for the air defence role,escorting three carrier task forces/groups (Viraat,Gorshkov and IAC-1),a number which will most probably remain with a larger 60,000t carrier acquired to replace the Viraat,plus a few-ideally 3 LHPDs with flat tops like the Mistral or Juan Carlos for the amphibious role,the IN requires large multi-role destroyers/cruisers of at least 12000t,which can carry an assortment of LR SAMs for air defence/BMD ( a small number of ships would be of little use and unless stationed along both coastlines defeating their main purpose protecting the carriers and land based missiles could be larger,swifter and more lethal),a QR anti-missile SAM ,a large main gun ,a gun/missile CIWS,a large number of Brahmos or other LR SSMs,plus anti-sub weapons/missiles/TTs and two large ASW/MR helos and at least one compact UAV.A minimum of 3 such vessels will be required.add to this about 12-18 DDGs of the Delhi (A,B,C) and Brahmos equipped Rajput class (which will also require replacement by 2020),24+ FFGHs of Shivalik (10+),Talwar (9),B/G class (6),18-20 corvettes of P-28 and Kukhri/Kora class and around 16-20 AOPVs,the size and capability of the surface fleet will be quite substantial apart from minor combatants like the missile craft,etc.The 16+ AOPVs should be capable of quick and easy add-on weaponry in a crisis,just as our current OPVs are Dhanush capable.
He is spot on reg. the need for more subs to sanitise choke points and used for sea denial,but for power projection,there is nothing like a carrier and a nuclear powered one better still for the job.Showing the flag around the region and beyond ,especiailly in a future era of extensive PLAN operations outside its traditional waters,is an absolute neccessity.As a good friend (starred landlubber) recently told me,the IN is the "force for the future".
