India has commissioned its third nuclear-powered submarine, INS Aridaman, at a ceremony in Visakhapatnam, presided over by Defence Minister Rajnath Singh. As the largest submarine in India's fleet, the Aridaman is equipped with nuclear-tipped missiles, enhancing the country's nuclear triad, which allows for a retaliatory strike by land, sea, or air. This submarine is designed for long-term underwater missions and is capable of launching nuclear weapons in response to attacks on Indian soil. The Aridaman features indigenous systems developed by Indian scientists and industry, marking a significant advancement in the country's naval capabilities. Singh emphasized the importance of a strong navy for national security, particularly in ensuring the safety of commercial shipping in sensitive maritime regions. The commissioning follows the earlier induction of INS Arighaat, India's second ship submersible ballistic nuclear (SSBN) submarine, in August 2024. Additionally, Singh noted that work has begun on the next major project for nuclear attack submarines (SSNs), which will be conventionally armed but nuclear-powered.
