India Nuclear Arsenal Reaches 190 Warheads
India’s nuclear arsenal has increased to an estimated 190 warheads, widening its lead over Pakistan’s estimated 170 warheads, according to the latest assessment by the Stockholm International Peace Research Institute.
India Nuclear Arsenal Estimate
The SIPRI Yearbook 2026 estimates that India had around 190 nuclear warheads as of January 2026, up from earlier assessments. Pakistan’s stockpile was estimated at about 170 warheads, giving India a lead of around 20 warheads over its western neighbour.
The report said both countries continued to modernise their nuclear forces during 2025, reflecting the continuing security competition in South Asia.
India Pakistan Nuclear Balance
India and Pakistan remain locked in a long-running nuclear rivalry shaped by conventional military tensions, border disputes and repeated crises. While India’s nuclear posture is linked to both Pakistan and China, Pakistan’s programme remains heavily focused on deterring India.
The latest estimates show India moving ahead in warhead count, but nuclear capability also depends on delivery systems, survivability, command structures and doctrine, not just the number of warheads.
SIPRI Warns On Global Nuclear Risks
SIPRI also warned that global nuclear risks are rising as arms-control frameworks weaken and nuclear-armed states continue to upgrade their arsenals. The institute said the world is entering a more dangerous period, with nuclear weapons again becoming central to security planning.
For India, the increase comes alongside efforts to strengthen land, air and sea-based nuclear delivery systems. The focus is on maintaining credible deterrence in a region where both Pakistan and China remain central security concerns.
