The\u00a0Nuclear Triad<\/strong>\u00a0of India is a three-sided military-force structure consisting of\u00a0ICBMs (land-based nuclear missiles)<\/strong>,\u00a0SSBNs\u00a0<\/strong>(nuclear-missile-armed submarines)<\/strong>, and\u00a0Strategic Bombers<\/strong>\u00a0(strategic aircraft with nuclear bombs and missiles)<\/strong>. The theory underlying the triad is that spreading the country\u2019s extensive nuclear arsenals across various weapons platforms and dimensions would provide a\u00a0Credible Minimum Deterrence (CMD)<\/strong>. In 2018, with the deployment of\u00a0INS Arihant (an SSBN)<\/strong>,a Strategic Strike Nuclear Submarine,\u00a0<\/strong>India got its fully operational Nuclear Triad.<\/p>\r\n

Components of India\u2019s Nuclear Triad<\/h2>\r\n

India\u2019s Nuclear Triad, as with other nations, comprises three components, each having the capability of a nuclear strike - Land, Air, and Naval (Sea).<\/p>\r\n

Land-based Components<\/h3>\r\n

It mainly includes missiles that can be launched from land-based platforms such as\u00a0ICBMs\u00a0<\/strong>(Inter-continental Ballistic Missiles), SRBMs\u00a0<\/strong>(Short Range Ballistic Missiles), etc.\u00a0<\/strong>The ICBMsare quite\u00a0responsive\u00a0<\/strong>and\u00a0lethal<\/strong>.<\/p>\r\n

    \r\n\t
  • ICBMs are deployed in hundreds of silos and can be launched and reach targets within minutes, creating a nearly insurmountable targeting problem for adversaries.\r\n\r\n
      \r\n\t
    • For example, the\u00a0Agni-V missile\u00a0<\/strong>can go up to a range of 5500 Km with nuclear warheads.<\/li>\r\n<\/ul>\r\n<\/li>\r\n\t
    • Other land-based missiles that can support the triad are\u00a0Prithvi, Akash, Trishul<\/strong>, etc.<\/li>\r\n<\/ul>\r\n

      Sea-based Component<\/h3>\r\n

      This component majorly includes the Ship Submersible Ballistic Nuclear Submarines\u00a0(SSBNs).<\/strong><\/p>\r\n

        \r\n\t
      • The SSBNs are considered survivable<\/strong>\u00a0because a portion of the SSBN fleet is always on patrol, making it very difficult for potential adversaries to track all of them, contributing to their survivability.\r\n\r\n
          \r\n\t
        • For example,\u00a0INS Arihant\u00a0<\/strong>with\u00a0K-15 Sagarika missiles\u00a0<\/strong>(700 Kms range) and\u00a0K-4<\/strong>\u00a0(3500 Kms range) missiles.<\/li>\r\n<\/ul>\r\n<\/li>\r\n\t
        • Also, the trials are going on with\u00a0INS Arighat\u00a0<\/strong>which has a possibility of getting inducted by\u00a02024<\/strong>.\r\n\r\n
            \r\n\t
          • It is more suitable to carry more K-4 missiles than INS Arihant.<\/li>\r\n<\/ul>\r\n<\/li>\r\n\t
          • The SSBNs play a crucial role in the Second Strike against any nuclear attack complementing the Nuclear Doctrine as their location is unknown.<\/li>\r\n<\/ul>\r\n

            Air-based Component<\/h3>\r\n

            It majorly includes the\u00a0Bombers which are considered as flexible for attacking.\u00a0<\/strong>The bomber aircraft are flexible and can resolve during a crisis and provide a variety of deployment and yield options when placed on alert.<\/p>\r\n

              \r\n\t
            • The aircraft that would work as bombers include the\u00a0Sukhoi Su-30MKI<\/strong>,\u00a0Mirage 2000H<\/strong>,\u00a0SEPECAT Jaguar,<\/strong>\u00a0and most importantly\u00a0Rafale.<\/strong><\/li>\r\n\t
            • The Land and air strike capabilities are controlled by\u00a0Strategic Forces Command<\/strong>, a part of the\u00a0Nuclear Command Authority<\/strong>.\r\n\r\n
                \r\n\t
              • NCA was created in\u00a02003\u00a0<\/strong>and is responsible for the\u00a0management\u00a0<\/strong>and\u00a0administration\u00a0<\/strong>of the country's tactical and strategic\u00a0nuclear weapons\u00a0<\/strong>stockpile.\r\n\r\n
                  \r\n\t
                • NCA is the\u00a0authority\u00a0<\/strong>responsible for command, control, and operational decisions regarding\u00a0India's nuclear weapons programme<\/strong>.<\/li>\r\n<\/ul>\r\n<\/li>\r\n<\/ul>\r\n<\/li>\r\n<\/ul>\r\n

                  Significance of India\u2019s Nuclear Triad<\/h2>\r\n

                  India is among very few countries (United States, Russia, China, India, and Pakistan<\/strong>) which have achieved the capability of nuclear triad. The Nuclear Triad has its own significance in providing security to a nation.<\/p>\r\n

                    \r\n\t
                  • Capability of Second Strike:<\/strong>\u00a0The Nuclear Triad helps the country to counter-attack a nation after being attacked by nuclear warheads.\r\n\r\n
                      \r\n\t
                    • This triad ensures that even after being hit by a nuclear warhead, one can counter the attacking nation.<\/li>\r\n<\/ul>\r\n<\/li>\r\n\t
                    • Balance of Power:<\/strong>\u00a0For India, this triad is very crucial, since it shares its borders with its\u00a0nuclear-empowered<\/strong>\u00a0adversaries such as\u00a0Pakistan\u00a0<\/strong>and\u00a0China<\/strong>.\r\n\r\n
                        \r\n\t
                      • Both countries have sophisticated arsenals and believe they have the assets to credibly harm India.<\/li>\r\n\t
                      • Having a nuclear triad, India is now aiming to counterbalance China\u2019s assertiveness in South Asia.<\/li>\r\n<\/ul>\r\n<\/li>\r\n\t
                      • Credible Minimum Deterrence:\u00a0<\/strong>It is one of the objectives of\u00a0India\u2019s Nuclear Doctrine<\/strong>\u00a0which is complemented by possessing a fully operational nuclear triad.\r\n\r\n
                          \r\n\t
                        • It provides sufficient deterrence from any attacking nation by creating a\u00a0fear of the consequences<\/strong>\u00a0(Second strike).<\/li>\r\n<\/ul>\r\n<\/li>\r\n\t
                        • Massive Retaliation:<\/strong>\u00a0As per the Nuclear Doctrine, India\u2019s second strike would be massive and the Triad supplements it.\r\n\r\n
                            \r\n\t
                          • Hence, the Triad provides\u00a0resilience\u00a0<\/strong>and\u00a0feasibility\u00a0<\/strong>to counter.<\/li>\r\n<\/ul>\r\n<\/li>\r\n<\/ul>\r\n

                            Limitations of India\u2019s Nuclear Triad<\/h2>\r\n

                            The deterrence of a nuclear triad depends on the vehicles (platforms) and the capabilities of missiles. The Nuclear Triad of India, though complete, still faces a few shortcomings.<\/p>\r\n

                              \r\n\t
                            • Regarding sea-based components:<\/strong>\r\n
                                \r\n\t
                              • There is a need for\u00a0more than one SSBN<\/strong>\u00a0(nuclear-powered ballistic missile submarine) to ensure continuous deployment at sea.<\/li>\r\n\t
                              • The K-15 missiles\u2019 utility is\u00a0limited by its 750 km range<\/strong>, which means that to counter China, submarines need to be present in the South China Sea to make the K-15 effective.<\/li>\r\n\t
                              • The INS Arihant has the capacity to carry a\u00a0lesser number<\/strong>\u00a0of long-range\u00a0K-4<\/strong>\u00a0missiles (still in development).<\/li>\r\n<\/ul>\r\n<\/li>\r\n\t
                              • Regarding Strategic Bombers:<\/strong>\r\n
                                  \r\n\t
                                • The air component of the triad includes nuclear warheaded\u00a0Strategic Bombers\u00a0<\/strong>for which India depends on other countries like Russia (Sukhoi<\/strong>), France (Rafale<\/strong>), etc.<\/li>\r\n\t
                                • This increases the\u00a0import burden<\/strong>\u00a0on the country as well. Thus, indigenisation of the platforms and missiles is the need of the hour.<\/li>\r\n<\/ul>\r\n<\/li>\r\n\t
                                • Regarding land-based components:<\/strong>\r\n
                                    \r\n\t
                                  • India has ICBMs as part of the triad but these can be tracked by Ballistic Missile Defence technology in the early phase of flight.<\/li>\r\n\t
                                  • Other advanced technologies such as\u00a0Fractional Orbital Bombardment Systems (FOBS)<\/strong>,\u00a0Hypersonic Glide Vehicles<\/strong>,\u00a0Hypersonic Cruise Missiles<\/strong>, etc. need to be developed, and these are in the development stage in India.<\/li>\r\n<\/ul>\r\n<\/li>\r\n<\/ul>","protected":false},"excerpt":{"rendered":"
