Fourth nuclear submarine with advanced arms launched in India

• India’s fourth nuclear-powered ballistic missile submarine, S4*, was launched into water at the Ship Building Centre in Visakhapatnam.

• The submarine is larger and more capable than the first, INS Arihant (S2).

• The S4* has significant indigenous content, with Indian industry heavily involved.

• India currently has two operational SSBNs: INS Arihant (S2), INS Arighaat (S3), and SSBN Aridhman (S4).

• The S4* carries the advanced 3,500 km range SLBM K-4, which will be the mainstay of India’s undersea nuclear deterrence
