India's INS Aridaman Submarine Set to Enhance Naval Nuclear Deterrence
Strengthening Maritime Security
India is poised to elevate its maritime security and nuclear deterrent capabilities. On Friday, Defense Minister Rajnath Singh hinted at the imminent induction of the country's third indigenous nuclear-powered submarine, INS Aridaman, through a compelling post on the social media platform 'X'.
Significance of INS Aridaman
He stated: "It's not just a word; it signifies power - 'Aridaman'!"
Equipped with long-range missile capabilities, INS Aridaman is expected to bolster India's sea-based nuclear deterrence. This submarine will enhance both its striking and survivability capabilities, aligning with the nation's nuclear doctrine.
Announcement During Visakhapatnam Visit
This announcement coincided with Singh's visit to Visakhapatnam, where he is set to commission the indigenously built advanced stealth frigate 'Taaragiri' into the navy. Visakhapatnam serves as the home port for India's nuclear submarines and is a key center for their construction.
Successful Trials and Future Plans
INS Aridaman has successfully completed its final phase of sea trials and is now ready to join the Strategic Forces Command. It will follow in the footsteps of its predecessors, INS Arihant (commissioned in 2016) and INS Arighat (set to join in August 2024).
Specifications of INS Aridaman
Weighing approximately 7,000 tons, Aridaman is slightly larger than previous submarines in its class. It features a more streamlined design for enhanced stealth and acoustic performance. The submarine is powered by an advanced 83 MW Pressurized Water Reactor (PWR) developed by the Bhabha Atomic Research Centre (BARC).
Enhanced Missile Capacity
Unlike its predecessors, Aridaman is equipped with eight vertical launch tubes, doubling the capacity of INS Arihant. This allows it to carry eight K-4 long-range missiles with a range of 3,500 km or 24 K-15 missiles with a range of 750 km. Its induction will enable India to maintain a "continuous deterrent capability at sea," ensuring that at least one nuclear-armed submarine is on patrol at all times.
Confirmation from Naval Chief
Earlier this year, Navy Chief Admiral Dinesh K. Tripathi indicated that INS Aridaman would be inducted into the navy between April and May. During the annual 'Pre-Navy Day' event in December 2025, Admiral Tripathi confirmed that this advanced submarine had entered its final testing phase.
