INS Aridhaman, commissioned on April 3, 2026, is India's latest nuclear-powered ballistic missile submarine, enhancing the country's sea-based nuclear deterrence as part of the Arihant-class fleet. Weighing approximately 7,000 tonnes, it features eight vertical launch tubes, allowing it to carry up to 24 K-15 ballistic missiles and eight K-4 missiles with a range of up to 3,500 km. This submarine is equipped with nearly 90 percent indigenous technology, including advanced sonar systems and sound-absorbing tiles, making it difficult to detect. INS Aridhaman plays a vital role in India's nuclear triad, which includes land, air, and sea capabilities, ensuring credible minimum deterrence. Its operational base will be Project Varsha near Visakhapatnam, enhancing its strategic reach. With this new addition, India solidifies its status as a major maritime power in the Indo-Pacific region, joining nations like the United States and Russia in possessing nuclear-powered submarines.
