Indian nuclear weapons, 2022

ABSTRACT The Nuclear Notebook is researched and written by Hans M. Kristensen, director of the Nuclear Information Project with the Federation of American Scientists, and Matt Korda, a senior research associate with the project. The Nuclear Notebook column has been published in the Bulletin of the Atomic Scientists since 1987. This issue examines the status of India’s nuclear arsenal, which includes a stockpile of approximately 160 warheads. India continues to modernize its nuclear arsenal, with at least four new weapon systems now 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 combat-ready. India is estimated to have produced enough military plutonium for 140 to 210 nuclear warheads but has likely produced only 160. Nonetheless, additional plutonium will be required to produce warheads for missiles now under development, and India is reportedly building several new plutonium production facilities. India’s nuclear strategy, which has traditionally focused on Pakistan, now appears to place increased emphasis on China, and Beijing is now in range of Indian missiles.
