an indigenous SSBN designed to carry a greater number of <\/span><b>long-range nuclear-tipped missiles<\/b><span style=\"font-weight: 400;\"> compared to its predecessors\u2014INS Arihant (commissioned in 2016) and INS Arighaat (2024).\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">This advancement strengthens India\u2019s ability to maintain a credible deterrent.<\/span><\/li>\n<\/ul>\n<h3><b>Strengthening India\u2019s Nuclear Triad<\/b><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The induction further consolidates India\u2019s <\/span><b>nuclear triad<\/b><span style=\"font-weight: 400;\">, which refers to the capability to launch nuclear weapons from land, air, and sea.\u00a0<\/span>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"2\"><span style=\"font-weight: 400;\">Land-based systems: Agni series missiles\u00a0<\/span><\/li>\n<li

style=\"font-weight: 400;\">India joins a select group of countries\u2014the US, Russia, China, and France\u2014that possess such capability.<\/span><\/li>\n<\/ul>\n<h3><b>Second-Strike Capability and Deterrence<\/b><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">India follows a \u201c<\/span><b>No First Use\u201d<\/b><span style=\"font-weight: 400;\"> nuclear doctrine, meaning nuclear weapons are intended only for deterrence and retaliation.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">In this context, SSBNs play a critical role by ensuring a second-strike capability.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Even if an adversary targets India\u2019s land and air bases in a first strike, SSBNs operating stealthily at sea can launch a retaliatory nuclear attack, thereby maintaining credible deterrence.<\/span><\/li>\n<\/ul>\n<h2><b>Features of INS Aridhaman<\/b><\/h2>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">INS Aridhaman is a 7,000-tonne nuclear-powered submarine equipped with eight vertical launch tubes, nearly double that of its predecessors.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">This allows it to carry a larger number of nuclear-capable missiles.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">It is powered by upgraded <\/span><b>nuclear reactors<\/b><span style=\"font-weight: 400;\">, enabling it to remain submerged for months without surfacing, significantly improving stealth and survivability.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The submarine can deploy:<\/span>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"2\"><span style=\"font-weight: 400;\">K-15 SLBMs with a range of over 700 km\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"2\"><span style=\"font-weight: 400;\">K-4 SLBMs with a range of around 3,500 km\u00a0<\/span><\/li>\n<\/ul>\n<\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">This combination enhances India\u2019s ability to strike targets at varying distances.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">India is also building a <\/span><b>fourth SSBN<\/b><span style=\"font-weight: 400;\">, expected to be larger and capable of carrying more K-4 missiles, further strengthening the country\u2019s sea-based nuclear deterrent.<\/span><\/li>\n<\/ul>\n<h2><b>Origins of India\u2019s Nuclear Submarine Programme<\/b><\/h2>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">India\u2019s nuclear-powered submarine project began over three decades ago, involving collaboration between the DRDO, private industry, and technical assistance from Russia.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The aim was to build an indigenous sea-based nuclear deterrent.<\/span><\/li>\n<\/ul>\n<h3><b>INS Arihant: The First Milestone<\/b><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">INS Arihant, launched in 2009 and commissioned in 2016, became India\u2019s first nuclear-powered submarine, giving the country a maritime nuclear strike capability for the first time.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">In 2018, Arihant completed its first deterrence patrol, marking the operationalisation of India\u2019s nuclear triad.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Later, in October 2022, it successfully launched a submarine-launched ballistic missile (SLBM) in the Bay of Bengal with high accuracy.<\/span><\/li>\n<\/ul>\n<h3><b>INS Arighaat: Technological Advancement<\/b><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The induction of the 6,000-tonne INS Arighaat in 2024 further strengthened India\u2019s nuclear strike capability.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">It is considered more technologically advanced than Arihant, incorporating improved design, engineering, and manufacturing techniques.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Its construction involved advanced R&amp;D, specialised materials, complex engineering processes, and skilled workmanship, reflecting India\u2019s growing expertise in submarine technology.<\/span><\/li>\n<\/ul>\n<h3><b>Nuclear Propulsion and Stealth Capability<\/b><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Both INS Arihant and INS Arighaat are powered by 83 MW pressurised light-water nuclear reactors, enabling them to remain submerged for long durations and operate with greater stealth compared to conventional diesel-electric submarines.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Together, these submarines form the backbone of India\u2019s <\/span><b>sea-based nuclear deterrent<\/b><span style=\"font-weight: 400;\">, enhancing survivability, stealth, and second-strike capability as part of the country\u2019s broader nuclear strategy.<\/span><\/li>\n<\/ul>\n<h2><b>Future Submarine Plans of India<\/b><\/h2>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">India is expanding its underwater capabilities through multiple initiatives.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">It is pursuing a nuclear-powered attack submarine (SSN) programme, under which two SSNs will be built indigenously, while one submarine will be leased from Russia, expected by 2027\u201328, to bridge immediate capability gaps.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Additionally, India is close to finalising the Project-75I submarine deal with Germany, where ThyssenKrupp Marine Systems will collaborate with Mazagon Dock Shipbuilders Ltd to build six advanced conventional submarines with Air Independent Propulsion (AIP) technology in India.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">However, there is still uncertainty regarding the acquisition of three additional Scorpene-class submarines.<\/span><\/li>\n<\/ul>\n<h2><b>India\u2019s Submarine Strength and Operational Capacity<\/b><\/h2>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">India currently operates 16 conventional submarines, in addition to its SSBN fleet.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">These include six Kalvari-class submarines built with France\u2019s Naval Group, four Shishumar-class, and seven Kilo (Sindhughosh)-class submarines.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">While the Navy is authorised to maintain a fleet of 18 submarines, about 30% are typically under refit at any given time, reducing the number of operational submarines available.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">In comparison, the United States operates 14 Ohio-class SSBNs and 53 attack submarines, while China has around 12 nuclear submarines, including six nuclear-powered attack submarines, highlighting the capability gap India aims to bridge.<\/span><\/li>\n<\/ul>\n<p><b>Source:<\/b><strong> <a href=\"https:\/\/indianexpress.com\/article\/explained\/ins-aridaman-the-significance-of-indias-third-nuclear-submarine-10617950\/\"
