The air force, seeking to canalise the budget to new fighter squadrons, has argued that the aircraft carrier is an outdated concept, and that land-based fighters, with their ranges extended by mid-air refuelling, can strike targets far out to sea, without the risk that aircraft carriers run of being sunk by anti-ship missiles, torpedoes, or “carrier killer” ballistic missiles like China’s Dong Feng–21D, which China claims can destroy enemy carriers 1,500 kilometres away.
Like predictions about the death of the battle tank, the hobbyhorse that aircraft carriers are anachronous has been conclusively rebutted, not least by the US Navy, which continues basing its power projection on the “carrier battle group”. To be sure, aerial refuelling allows shore-based fighters to strike targets at greater ranges. The plan to station fighters on island bases — like that “unsinkable aircraft carrier”, the Andaman and Nicobar Islands — adds weight to the air force’s argument. But shore-based fighters must return to base after striking a far-away target or risk running out of fuel. They have no “persistence” over areas hundreds of kilometres from their shore bases. In contrast, an aircraft carrier, escorted by a flotilla of multi-role destroyers and frigates, anti-submarine warfare corvettes, a submarine or two and a range of airborne assets, can project power and dominate areas thousands of kilometres out to sea, where shore based fighters cannot reach even with refuelling.
INS Vishal will be India’s first real “power projection” aircraft carrier. None of the navy’s earlier carriers — the original 16,000 tonne INS Vikrant and the 24,000 tonne INS Virat, both decommissioned now, or even the 45,000 tonne INS Vikramaditya, which is currently in service, or the new 40,000 tonne INS Vikrant — can embark more than about 30 aircraft. That is insufficient for the dual task of protecting the “battle group” and also dominating the seas around.
In contrast, INS Vishal, a 65,000 tonne giant, will embark 54 aircraft, including fighters, electronic warfare aircraft, airborne command posts and anti-submarine helicopters. While less versatile than the US Navy’s 100,000 tonne supercarriers, the Vishal, along with another ten-odd helicopters based on its accompanying warships, can both protect and dominate.
Senior defence officers have described to Business Standard the economics of an indigenous, conventionally powered IAC-2 — since nuclear propulsion was ruled out after Bhabha Atomic Research Centre (BARC) said it would take 15-20 years to develop a nuclear reactor large enough for a carrier. The cost of building such a carrier at Cochin Shipyard is estimated at Rs 400 billion.
Another Rs 40-500 billion would be needed for a carrier aviation wing — the aircraft it will embark. While the navy will operate three carriers once INS Vishal joins Vikramaditya and Vikrant, senior naval planners say two “air wings” will suffice since the need to refit one of the carriers, turn by turn, would leave two operational at any time. Two air wings, therefore, would rotate between three aircraft carriers.
Since India already has 45 Russian MiG-29K/KUB fighters, mostly based on the Vikramaditya, the navy has initiated the purchase of anther 57 “multi-role carrier-borne fighters (MRCBF) for its second air wing. In this procurement, which began in January 2017, Boeing’s F/A-18E/F will compete with Dassault’s Rafale-Marine, Saab’s Sea Gripen and the MiG-29K.
