India Expands Nuclear Arsenal to 190 Warheads, Focuses on China Deterrent

India has expanded its nuclear arsenal to approximately 190 warheads, up from previous estimates, according to the Stockholm International Peace Research Institute (SIPRI) Yearbook 2026. The report highlights that global nuclear risks are escalating as the world's nuclear-armed states expand and modernize their arsenals. While India continues to build its deterrent, its nuclear modernization programme is increasingly focused on developing longer-range weapons capable of reaching strategic targets across China.

The expansion comes amid a broader international trend where nuclear-armed nations are walking away from long-standing disarmament commitments. Rising geopolitical friction, particularly between India and China, as well as the ongoing border tensions, have compelled New Delhi to enhance its second-strike capability and bolster its nuclear triad. SIPRI's findings indicate that both India and Pakistan continued to develop new types of nuclear delivery systems, but India's recent developments are strategically oriented toward a deterrent capability against China's deep-territory military installations.

This development is set to intensify regional security dynamics in South Asia, leading to heightened surveillance and defense preparedness by neighboring states. India is expected to proceed with testing and inducting its longer-range ballistic missiles, such as the Agni series, and deploying more nuclear-powered ballistic missile submarines (SSBNs) to solidify its maritime deterrence. Strategically, this places India in a stronger position to negotiate in multilateral forums, although it may trigger a corresponding build-up or modernization effort by Pakistan and China.
