India Deploys Nuclear Warheads Operationally for the First Time: Insights from SIPRI Yearbook 2026

India has taken a measured step in enhancing its nuclear readiness by operationally deploying approximately 12 nuclear warheads for the first time, according to the Stockholm International Peace Research Institute’s (SIPRI) Yearbook 2026. This development reflects the country’s ongoing efforts to strengthen its strategic deterrence capabilities in response to the evolving security landscape in the region.

The report estimates India’s total nuclear arsenal at around 190 warheads as of January 2026, marking a modest increase from 180 the previous year. Of these, 12 are now assessed as deployed with operational forces, while the remainder are held in storage. This shift is primarily associated with the maturation of India’s sea-based nuclear deterrent, particularly through its nuclear-powered ballistic missile submarines (SSBNs).

India’s Nuclear Posture and Doctrine

India’s nuclear strategy has long been guided by the principles of credible minimum deterrence and a No First Use policy. Under this framework, nuclear weapons serve as a tool of last resort, intended solely for retaliation against a nuclear attack. Historically, the country maintained a de-mated posture, with warheads kept separate from delivery systems in peacetime to ensure tight political control.

The limited deployment of warheads does not signal a departure from these core principles. Instead, it represents a gradual enhancement in operational readiness, driven by technological advancements in the nuclear triad — encompassing air, land, and sea-based platforms. This includes progress with the INS Arihant-class submarines and associated missile systems, which improve survivability and second-strike reliability.

Regional Security Dynamics

The modernisation of India’s nuclear forces is shaped by the broader strategic environment, particularly the rapid advancements by neighbouring powers. China continues to expand its nuclear capabilities at a notable pace, with SIPRI estimating its arsenal at 620 warheads, including 34 deployed. This growth has prompted India to focus on longer-range delivery systems capable of addressing threats across greater distances.

Tensions with Pakistan also remain a factor, with both nations advancing their missile technologies and delivery platforms. Pakistan’s arsenal is estimated at around 170 warheads. These regional dynamics underscore the importance of maintaining a robust and credible deterrent to safeguard national security and regional stability.

The Global Nuclear Context

SIPRI’s findings highlight a concerning global trend. The nine nuclear-armed states collectively possess an estimated 12,187 warheads, with about 9,745 in military stockpiles and roughly 4,012 deployed. Major powers like Russia and the United States account for the bulk of these, but nearly all countries are engaged in modernisation programmes amid weakening arms control frameworks.

The report warns of heightened risks stemming from increased reliance on nuclear weapons, geopolitical rivalries, and reduced transparency. In this environment, India’s approach remains restrained, with its arsenal significantly smaller than those of the leading nuclear powers, consistent with its policy of minimum deterrence.

The MGMM Outlook 

India’s reported operational deployment of a limited number of nuclear warheads reflects the gradual evolution of its strategic capabilities rather than any shift in its long-standing nuclear doctrine. The development highlights the strengthening of the country’s nuclear triad, particularly its sea-based deterrent, which enhances survivability and reinforces the credibility of India’s second-strike capability. Maintaining operational readiness while adhering to the principles of credible minimum deterrence and No First Use demonstrates a balanced approach to national security.

The changing regional and global security environment has made strategic modernisation increasingly important. With neighbouring countries expanding their capabilities and major powers continuing nuclear upgrades, India’s measured steps appear aimed at preserving stability and ensuring effective deterrence. The relatively modest size of India’s arsenal, combined with its emphasis on restraint and responsible stewardship, underscores its commitment to safeguarding national interests while contributing to broader regional security.
