In this thoughtful segment of CTRL ALT DEFENCE, Shiv Aroor and Vishnu Som discuss one of the most sensitive and rarely spoken aspects of India’s defence strategy — its nuclear submarine force. With tensions running high during Operation Sindoor and the real possibility of escalation, the question naturally arises: was India’s sea-based nuclear deterrent quietly standing by? Without revealing any classified details, the conversation explores what we can say about the Arihant-class submarines, their role in deterrence, and why they matter in moments of near-conflict — not just with Pakistan, but in a broader strategic context that includes China.
