![]() French aerospace company Safran in cooperation with India’s DRDO plans to co-produce jet engines for India’s 5 th generation fighter. When the hydrogen is mixed with oxygen, it generates electricity to charge the submarine’s batteries and produces water used in the cracking process.Īsia Times has reported on France’s assistance to India’s 5 th generation fighter and conventional submarine programs. India’s new AIP system is most likely derived from Naval Group’s Fuel Cell Second Generation (FC2G) model, which cracks diesel fuel in a reformer to extract hydrogen, using liquid oxygen and nitrogen as oxidizers. 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. Most PROBABLE and HIGHLY recommended topics "you should never miss" to prepare to crack UPSC Prelims Examination.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. The success of INS Arihant gives a fitting response to those who indulge in nuclear blackmail “In an era such as this, a credible nuclear deterrence is the need of the hour. Calling it a major achievement for the country, Prime Minister said that INS Arihant will help in protecting the country from external threats and contribute to the atmosphere of peace in the region.On August 10, 2013, Arihant’s 83 MW nuclear reactor got “critical”.First 6,000-tonne ATV, named INS Arihant, launched into the water at ship-building centre in Visakhapatnam in 2009.However, the actual construction of 3 SSBNs began in the 1990s under secret Advanced Technology Vessel (ATV) project. The hunt for a nuclear submarine in India began in the 1970s.Though the missiles on INS Arihant, with a range of 750km and 3,500km, pale in comparison to missiles on Chinese, the US and Russian submarines, which have ranges of well over 5,000 km, yet the nuclear-triad has been a critical addition to India’s arsenal.At the third sport are the European powers, France and the UK, with 10 to 12 nuclear submarines each. The US, with 70+ nuclear submarines, leads the race with Russia at the second spot with approximately 30 nuclear submarines.The construction of the second one, INS Aridhaman, is also almost complete now, with its delivery slated for 2018. INS Arihant is the first of three such SSBNs constructed under the secretive ATV (advanced technology vessel) programme launched decades ago. ![]() INS Arihant has undergone a host of surface and “dived” sorties during its trials to prove its sea-worthiness. ![]()
