India Commissions Fourth Nuclear-Missile Submarine

Amid tensions with Canada, India quietly launched its fourth SSBN submarine at Visakhapatnam’s Ship Building Center to bolster nuclear deterrence. With 75% indigenous content, the S4* submarine is armed with 3,500 km-range K-4 missiles. India plans to commission INS Aridhaman next year, while nuclear-powered attack submarines are being developed to strengthen Indo-Pacific security.
