India’s nuclear posture has entered a new phase with the Stockholm International Peace Research Institute’s latest yearbook noting that twelve of its estimated 190 warheads are now operationally deployed.
This means they are positioned with active military forces, mated with delivery systems, and ready for use. It marks the first time India’s arsenal has been classified in this way, reflecting a shift towards greater readiness.
The report highlights India’s increasing reliance on cannisterised Agni-series missiles. These systems allow warheads to be stored in sealed launch tubes, enhancing survivability and reducing launch preparation times. Such developments suggest India is moving closer to a model of deterrence that places emphasis on rapid response and secure second-strike capability.
Although the deployment of twelve warheads sounds alarming, analysts caution that the alarm may not be warranted. India has not crossed a strategic threshold nor abandoned its long-standing ‘no first use’ policy. This doctrine remains central to India’s nuclear strategy, committing the country to use nuclear weapons only in retaliation against a nuclear attack.
India’s nuclear arsenal continues to mature into a triad of land-based missiles, aircraft, and sea-based systems. The operational deployment of a small number of warheads reflects an incremental evolution rather than a radical transformation. It is designed to strengthen deterrence credibility without signalling aggressive intent.
The SIPRI yearbook also places India’s developments in a global context. Nine nuclear-armed states collectively hold over 12,000 warheads, with the United States and Russia accounting for the vast majority. China’s arsenal has also grown, with several warheads now classified as deployed. India’s entry into the category of states with operationally deployed warheads underscores the broader trend of nuclear powers enhancing readiness.
Regionally, Pakistan maintains a stockpile of around 170 warheads and continues to develop new delivery systems. India’s modest deployment is therefore seen as part of a balancing act within South Asia, ensuring survivability and credibility of deterrence while avoiding destabilising escalation.
The operational deployment of twelve warheads is symbolic as much as it is strategic. It signals India’s confidence in its evolving nuclear infrastructure, particularly the reliability of cannisterised missiles and sea-based deterrence patrols. Yet it also demonstrates restraint, with only a small fraction of its arsenal placed on active duty.
India’s nuclear policy remains rooted in deterrence rather than warfighting. The deployment of operational warheads is intended to reinforce the credibility of its posture, ensuring adversaries cannot dismiss its retaliatory capability. At the same time, India continues to project itself as a responsible nuclear power adhering to its declared doctrine.
