Sources confirmed Aridhaman has been inducted, following INS Arihant (2016) and INS Arighaat (2024), taking India’s operational SSBN fleet to three for the first time. This meets the minimum requirement for sustained deterrent patrol cycles, with at least one submarine deployed at all times while others undergo maintenance and training. SSBNs are considered the most dependable second-strike capability given their stealth and survivability, forming the bedrock of India’s nuclear doctrine of credible minimum deterrence and no-first-use. India currently operates a submarine fleet of around 17 boats, including 3 SSBNs and the rest diesel-electric platforms such as the Kalvari-class, Kilo-class and Shishumar-class submarines. The Navy has also revived its long-pending plan for at least six nuclear-powered attack submarines (SSNs) under Project 77, with work on two underway.
