Defence Minister Rajnath Singh hinted at the launch of India’s third indigenously built nuclear-powered submarine, INS Aridhaman, in a post on X. He described it as “not a word, it’s power, ‘Aridhaman’.” Notably, INS Aridhaman has completed its final sea tests and will soon become part of the Strategic Forces Command. This submarine comes after INS Arihant, which joined in 2016, and INS Arighaat, commissioned in August 2024.
The submarine displaces around 7,000 tonnes, slightly larger than its predecessors, and features a more streamlined hull for improved stealth and acoustic performance. It is powered by an upgraded 83 MW pressurised water reactor developed by the Bhabha Atomic Research Centre.
Aridhaman carries eight vertical launch tubes double the capacity of INS Arihant allowing it to deploy either eight K-4 long-range missiles with a 3,500 km range or up to 24 K-15 missiles with a 750 km range. This capability ensures continuous at-sea deterrence, keeping at least one nuclear-armed submarine on patrol at all times.
