India has significantly expanded its nuclear weapons inventory, adding an estimated 30 new warheads in recent years, according to a report released by a prominent United States-based policy research organization focused on nuclear security.
The study, which analyzed open-source intelligence and satellite data, places India's current nuclear stockpile at approximately 190 warheads, up from earlier estimates that ranged between 155 and 160. The assessment indicates a steady and deliberate pace of expansion consistent with India's stated nuclear doctrine and its perceived strategic challenges on two fronts.
New Delhi has long maintained that its nuclear program is driven primarily by the threat posed by China, which conducted its first nuclear test in 1964 and has since built a substantially larger arsenal exceeding 500 warheads. Pakistan, India's other regional rival, is estimated to possess over 170 nuclear warheads, creating a complex triangular nuclear dynamic in South Asia.
India officially adopted a No First Use (NFU) policy in 1999, declaring that it would not be the first to use nuclear weapons in any conflict and reserving the right to respond with massive retaliation if attacked with nuclear ordnance. However, defense analysts have noted that New Delhi's modernization efforts include developing delivery systems capable of striking deep into Chinese territory, including submarine-launched ballistic missiles and land-based missiles with extended ranges.
The latest estimate was derived through a combination of fissile material production analysis, satellite imagery of nuclear facilities, and assessments of India's military modernization programs. India operates several plutonium production reactors and has been expanding its enrichment capabilities at facilities in Kota and elsewhere across the country.
China's Ministry of Foreign Affairs responded to concerns about regional nuclear dynamics by emphasizing the need for all nuclear-armed states to commit to no-first-use policies and to reduce their arsenals for global strategic stability.
Pakistani officials have traditionally argued that India's growing stockpile necessitates continued nuclear modernization on their part as well, perpetuating what experts describe as a slow but persistent arms race in the region.
The United States, through various non-proliferation frameworks and bilateral agreements, has monitored India's nuclear developments closely since New Delhi conducted its first underground nuclear test in 1974 and followed up with additional tests in 1998.
