Bolstering deterrence through submarine dominance

What Happened

Defence Minister Rajnath Singh's April 3 social media post suggested India commissioned INS Aridhaman, its third nuclear ballistic missile submarine. Launched in 2009, it follows INS Arihant (2016) and INS Arighat (2024). The 7,000-tonne vessel reportedly carries up to 24 K-15 Sagarika missiles and eight K-4 or K-5 nuclear-tipped missiles, exceeding previous submarine capabilities. Another submarine in the class may commission next year.
