India's Nuclear Arsenal Reaches Estimated 190 Warheads Amid Ongoing Modernization

India's nuclear weapons stockpile has expanded to an estimated 190 warheads, according to a comprehensive new assessment released by the Federation of American Scientists (FAS). Authored by Hans Kristensen, director of the FAS Nuclear Information Project, the report titled "India's Nuclear Weapons 2026" provides a detailed breakdown of the nation's evolving strategic capabilities, combining open-source government data, commercial satellite imagery, and proliferation tracking.
Composition and Modernization of India's Strategic Arsenal
The latest evaluation indicates that India's nuclear inventory includes more than 160 warheads deployed for operational launchers, alongside roughly 30 additional warheads currently under development to equip upcoming missile systems. As part of its broader defense modernization strategy, New Delhi has actively deployed several advanced weapon systems in recent years while concurrently testing and developing platforms designed to replace or complement existing nuclear-capable aircraft, ground-based launchers, and sea-based delivery assets. Analysts note that the nation's warhead stockpile is poised for further growth as new delivery systems transition from development to operational deployment.
Plutonium Stockpiles and Warhead Manufacturing Estimates
According to data compiled by the International Panel on Fissile Materials, India is estimated to have produced approximately 730 kilograms of weapons-grade plutonium, with a margin of about 170 kilograms. Calculating on the basis of roughly four kilograms of plutonium per warhead, this fissile reserve is theoretically sufficient to manufacture between 140 and 225 nuclear warheads. However, experts emphasize that these figures involve analytical precautions, given that technical progress on advanced boosted fission and thermonuclear warhead designs remains subject to uncertainty since the 1998 Pokhran-II underground nuclear tests. Furthermore, defense researchers highlight that India is unlikely to have utilized its entire plutonium inventory for warheads, keeping portions in strategic reserve while sizing its active arsenal according to the operational capacity of available launchers.
Adherence to Credible Minimum Deterrence and No-First-Use Policy
Despite ongoing technological upgrades and the steady expansion of its delivery architecture, India remains steadfastly committed to its foundational strategic doctrines. Formally adopted following the Pokhran-II nuclear tests in 1998, the nation continues to strictly adhere to its 'no-first-use' (NFU) policy and the maintenance of a credible minimum deterrent. Government officials recently reaffirmed to Parliament that India's nuclear posture remains defensive, aimed at ensuring national security through reliable retaliatory deterrence rather than aggressive regional expansionism.
