India Shifts Nuclear Posture With First Peacetime Warhead Deployment

The SIPRI Yearbook 2026 highlights this departure from India’s traditional "de-mated" doctrine, which historically required warheads to be assembled with delivery systems only during moments of severe crisis. Experts suggest that the adoption of canister-based missile systems and the expansion of sea-based deterrence patrols have facilitated this shift toward maintaining a portion of the arsenal in a state of immediate readiness.

While India’s stockpile has grown from 180 to 190 units, it remains dwarfed by China’s 620 warheads. The modernization of the Indian arsenal is increasingly focused on longer-range capabilities designed to reach targets deep within Chinese territory. This recalibration serves as a dual-deterrent strategy, balancing the regional rivalry with Pakistan—which holds 170 warheads—against the broader strategic competition with Beijing. Globally, Russia and the United States continue to dominate the landscape, holding a combined inventory of over 10,000 weapons, maintaining a scale of destruction that far exceeds the regional power dynamics seen in South Asia.
