India’s nuclear deterrence capabilities are set to receive a significant boost with the upcoming commissioning of its second nuclear-powered ballistic missile submarine (SSBN), INS Arighat. According to Janes, a leading defense intelligence provider, the commissioning is expected by the end of 2024.

INS Arighat will join its predecessor, INS Arihant, which was commissioned in 2016. This marks a crucial step in India’s development of a credible nuclear triad – the ability to deliver nuclear weapons by land, sea, and air.

The submarine, launched in Visakhapatnam in 2017, is reported to be 111.6 meters long and displace 6,000 tonnes. It is powered by an 82.5 MW pressurized light water reactor (LWR) developed with Russian assistance and boasts a top speed of 24 knots while submerged.

This development comes amidst a backdrop of India’s ongoing construction of a third SSBN, details of which remain undisclosed. The addition of INS Arighat to the Indian Navy’s arsenal will significantly enhance India’s strategic nuclear deterrence capabilities.
