Aridhaman and Carriers

Around a  fortnight from today, the fueled up INS Aridhaman, the second nuclear-powered ballistic missile-firing submarine will be officially commissioned into the Indian Navy. It will be the pleasant duty of the new Defence Minister Nirmala Sitharaman to actually break a coconut — not a champagne bottle — on the hull of the SSBN.

This too is an Arihant-class boat but with more onboard firepower — 8 vertical launch tubes for the 1,500 km range K-15 and 2,500km range K-4 Mk-1 (seaborne Agni-III) missiles  — with the 5,000km range K-5 Mk-II (seaborne Agni-V) missile under development but coming up fast. The weapon mix will of course be determined by the aim of the nuclear counter-strike mission. In comparison, Arihant carries, besides the K-15, also the K-4 — but has available only 4 missile silos aft of the conning tower.

In fact, the Indian Arihant-class SSBN is far larger and more powerful than advertised by the government. Experts are convinced the Arihant displaces some 8,000 tonnes as against its publicized tonnage of 6,000 tonnes. The follow-on sub — Aridhaman and the two other SSBNs in this class are larger still.

Naturally, this sort of tonnage cannot be driven by a puny 90MW miniaturized light water reactor. Matching the displacement with the power plantwould put the latter at anywhere between 120MW-150MW for the Arihant, and nearer to 200MW for the Aridhaman.

The SSBN would not have been possible — it must be gratefully admitted, without seminal help and assistance from Russia, which has been surprisingly catholic in parting with strategic technologies. Those in the Indian military enamoured by Western tech and imports, should sit down and enumerate what tech the three armed services have actually received from the US and France before they begin yapping incessantly about the so-called mil high-tech Western countries supply and are prepared to in the future. If anybody in the GOI/MOD/armed services are even a little honest they will realize that the sole aim of the arms industry is to sell gullible 2nd rate states 2nd rate equipment dressed up with lots of bells and whistles to impress the yokels. Or, to sell technology, such as the electro-magnetic aircraft launch system for carriers their own services are finding hard to absorb, cost-wise.

The EMALS on the USS Gerald Ford nuclear-powered aircraft carrier, for instance, cost the American Navy some $3 billion. General Dynamics wants upwards of $5-$6 billion for each EMALS unit sold to, yea, the sucker — India. This while Washington has made it plain that this will not come with the nuclear reactor (required to generate the enormous power to drive the EMALS) the Indian naval brass desperately desired. EMALS with several GE LM 2500 gas turbine power packs makes little sense.

As it is, aircraft carriers are dead in the water with supersonic cruise missiles such as the Brahmos; with hypersonic weapons soon coming through large ships will become all the more vulnerable. Not that any of this will deter the naval aviation types — not surprisingly graduates of the US Naval War College. Except the US Navy with a ship strength of 370 bottoms deploys as escort flotilla a minimum of 5-7 frigates/missile destroyers and 1-2 submarines pulling picket duty. Translate that into IN terms, and most of the capital ships will be not out there asserting presence, showing flag, doing sea control but protecting the carriers. Should MOD/GOI approve 3 aircraft carriers, it will mean 15-21 surface combatants pulling police duty for the carriers out of a strength of some 50 odd fighting ships. It will be a bit like the hordes of police and NSG protecting our VVIP netas even as there are no police to spare for keeping law and order in the streets. Moreover, carriers are impressive in peace time; in war they are, what, sitting ducks?
