Being the third nuclear-powered ballistic missile submarine (SSBN) in the country, INS Aridhaman contributes greatly to the second-strike capability of India and makes it one of the select few countries with a developed nuclear deterrence system. This milestone was developed under India&#8217;s Indigenous Nuclear Submarine Program, highlighting the country&#8217;s increasing technological proficiency and investment in national security. Additionally, the maritime component of the Indian Nuclear Triad has been enhanced.<\/span><\/p>\n<h2><span style=\"font-weight: 400\">Key Features &amp; Strategic Importance of INS Aridhaman<\/span><\/h2>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">The third nuclear-powered ballistic missile submarine is INS Aridhaman, which enhances the country&#8217;s defence capabilities in terms of underwater defence and long-term strategic preparedness.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">It enhances the maritime component of the Nuclear Triad, which guarantees a believable and survivable nuclear retaliation.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">The submarine increases the second-strike capability of India, which will enable it to respond safely to any attack by the United States of America, even after a nuclear attack.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">It is developed with high-level stealth capabilities and would have a low acoustic signature, which would be very difficult to detect by enemy sonar systems.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">It has a nuclear reactor, which allows it to stay submerged for long periods of time, thus enabling long-range and continuous patrol missions.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">It is also fitted with submarine-launched ballistic missiles (SLBMs), which have greatly increased the strategic strike capability of India.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">It is the result of developing under the domestic Advanced Technology Vessel (ATV) programme in India, which indicates an increase in self-reliance in defence production.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">The submarine is very flexible in its operations, as it can deploy to large areas of the ocean, such as the Indo-Pacific.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">It improves the general strength and deterrence power of the Indian Navy during contemporary naval war.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">It increases the geopolitical status of India by placing it among the few countries having advanced nuclear submarines.<\/span><\/li>\n<\/ul>\n<h2><span style=\"font-weight: 400\">MCQs on Indian
