According to a report by the Stockholm International Peace Research Institute (SIPRI), India has potentially shifted its nuclear strategy by deploying 12 nuclear warheads on delivery systems, including possibly one nuclear submarine. This marks a notable change from India's previous practice of keeping warheads and delivery systems separate. The report states that India's nuclear arsenal has grown to 190 warheads, increasing from 180. Despite this shift, India continues to adhere to its no-first-use policy regarding nuclear weapons. The assessment indicates that India may be mating some warheads with their launchers during peacetime, reflecting advancements in its nuclear triad, which comprises aircraft, land-based missiles, and nuclear-powered submarines. The report also notes that while India's nuclear capabilities are expanding, Pakistan's stockpile remains unchanged at around 170 warheads. Both nations are reportedly developing new delivery systems, with India recently testing an intermediate-range missile featuring multiple independently targetable re-entry vehicle (MIRV) technology.
