The report did not mention specifics about the AIP’s performance, but did say it is unique in generating hydrogen onboard instead of storing it aboard in liquid form. The report cites a DRDO statement that says senior officials of DRDO New Materials Research Laboratory (NMRL) and Naval Group signed the agreement to extend cooperation for the detailed design phase of integrating India’s indigenous AIP into the INS Kalvari, with Naval Group certifying the integration. ![]() This month, Indian Express reported that Naval Group France and India’s Defense Research and Development Organization (DRDO) had signed an agreement to develop fuel cell AIP to be retrofitted on the first-of-class INS Kalvari, a derivative of the French Scorpene-class submarine. The SSBNs also impart India with a second-strike capability, sharpening India’s nuclear deterrent vis-à-vis China and Pakistan.France and India have signed an agreement to cooperate on air-independent propulsion (AIP) technology to upgrade the latter’s Kalvari-class submarines, deepening the growing strategic relationship between the two countries.ĪIP technology allows conventional submarines to stay submerged for weeks at a time, approaching the underwater endurance of nuclear submarines. India’s rapidly mutating submarine fleet is key to expanding the country’s maritime footprint in the Indo-Pacific region. India’s 5,000-kilometre K5 is an advanced stage of development, further beefing up India’s nuclear deterrent. With a range of 3,500 kilometres, they are part of providing an effective nuclear deterrent against both China and Pakistan. The Arihant is equipped to carry K4 nuclear missiles. On the contrary, the Arihant class SSBNs will not only be powered by an atomic engine, they will also board Submarine Launched Ballistic Missiles (SLBMS). While the SSN subs will be powered by a long -endurance nuclear engine, they will not board atomic weapons. With all the Kalvari class subs boarding AIP technology, the Indian navy will have state-of the art submarine fleet, which would be spearheaded by SSN and SSBNs. The agreement also imparts a major boost to ‘Aatmanirbhar Bharat’, doctrine announced earlier by Prime Minister Narendra Modi, to spur Indian manufacturing for the world. The government has reportedly also decided not to close the Kalvari class production line at the Mumbai based Mazagon Docks Ltd., opening the gates for the production induction of many more subs of this type, equipped with AIP technology. The Indian Navy has already inducted five Kalvari class subs, while the sixth platform, Vashgeer is expected to enter Indian pens later this year. The development also showcases India-France strategic partnership, as DRDO’s Naval Materials Research Laboratory (NMRL) has signed an agreement with the Naval Group France, which will certify AIP design for integration in the submarines.Īfter Kalvari-the first in the series-the rest of the 5 Kalvari class subs, will also be equipped with AIP systems, boosting the collective power of India’s submarine fleet manifold. Once it is modernised, the Kalvari, a variant of the French Scorpeen sub, will no longer have to frequently surface for refuelling-a time when the platforms can be picked and attacked. India’s effort to modernise its submarine force is set to take a giant leap with the fitment of the home-grown Air Independent Propulsion (AIP) system, developed by the Defence Research Development Organisation (DRDO), in INS Kalvari.Įquipped with AIP technology, the Kalvari will be able to stay underwater for a long time, significantly adding to its lethality. ![]()
