• India’s nuclear arsenal is estimated at around 190 warheads in 2026, with 12 reportedly placed into operational deployment for the first time in official strategic assessments
• Operational deployment means nuclear warheads are directly integrated with delivery systems and kept in immediate readiness with active military units for potential use
• The information is based on the Stockholm International Peace Research Institute 2026 Yearbook, which tracks global armaments and international security developments
• India follows a declared no first use nuclear doctrine, under which nuclear weapons are used only in response to a confirmed nuclear attack
• The doctrine is supported by credible minimum deterrence and strict civilian control over nuclear forces through centralized command structures
• Sea-based deterrence relies on Arihant class nuclear ballistic missile submarines that provide survivable second strike capability through underwater stealth deployment
• Agni-series missiles use canisterisation technology, storing missiles in sealed launch tubes to improve mobility, safety, and rapid launch readiness
• The Nuclear Command Authority of India manages nuclear forces through a Political Council and an Executive Council responsible for command and operational decisions
