India’s nuclear arsenal is estimated at about 190 warheads, according to a report by the US nonprofit policy think tank Federation of American Scientists (FAS). The FAS assessment is based on an analysis of open-source material, state-originating information, and commercial satellite imagery. The report also says India continues to modernise its nuclear delivery capabilities, with additional weapon systems and missile-related warheads expected to come online.

The FAS estimate suggests India has more than 160 warheads for operational launchers, alongside further warheads associated with new missiles under production. It links the estimate to plutonium production calculations, saying India may have produced about 730 kg (plus or minus 170 kg) of weapon-grade plutonium by the beginning of 2026, which could theoretically support between 140 and 225 warheads depending on assumptions. The report emphasizes uncertainties, including possible reserve holdings and unknowns around warhead design and how much plutonium has been converted.

Indian outlets summarise the figure and highlight ongoing modernisation and missile development, while the underlying FAS report stresses methodology and caveats regarding the relationship between plutonium stocks, warhead designs, and the number of delivery systems capable of using them.
