Indian nuclear weapons, 2024

India continues to modernize its nuclear arsenal, with at least four new weapon systems and several new delivery platforms under development to complement or replace existing nuclear-capable aircraft, land-based delivery systems, and sea-based systems. Several of these systems are nearing completion and will soon be fielded. We estimate that India may have produced enough military plutonium for 130 to 210 nuclear warheads but likely has produced only around 172, although the country's warhead stockpile is likely growing. The Nuclear Notebook is researched and written by the staff of the Federation of American Scientists' Nuclear Information Project: director Hans M. Kristensen, associate director Matt Korda, senior research associates Eliana Johns and Mackenzie Knight.
