India's nuclear warhead stock rises to 190, overtaking Pakistan

The Stockholm International Peace Research Institute (SIPRI) yearbook for 2026 estimates that India now possesses about 190 nuclear warheads, up from roughly 180 a year earlier. Pakistan’s stock is estimated at around 170 warheads, placing India ahead in the regional arms tally.

India is also moving toward multiple independently targetable reentry vehicle (MIRV) capability and has begun limited deployment of nuclear warheads on its sea‑based ballistic missile submarines (SSBNs) during peacetime – a departure from its previous practice of separating warheads from launch platforms. The adjustments are framed as responses to evolving security challenges, particularly from China and Pakistan, and aim to strengthen India’s second‑strike deterrence.

These developments signal a shift in South Asian nuclear posture, with both nations continuing to expand delivery systems while managing the risk of escalation.
