The Stockholm International Peace Research Institute released its annual global armaments yearbook recently.
The report reveals a striking assessment regarding India's strategic posture for the first time in modern history.
Out of an estimated 190 nuclear warheads, exactly 12 are now classified as operationally deployed.

Deploying 12 operational warheads does not mean India is adopting an offensive nuclear strategy.
Instead, this step shows that India is steadily strengthening its second-strike capability to retaliate after absorbing an attack.
This development fully supports India's long-standing No First Use (NFU) doctrine and its Credible Minimum Deterrence strategy.

India's total nuclear warheads reached 190, showing an increase from 180 in the year 2025.
Out of this total stockpile, exactly 12 warheads are currently in active operational deployment.
The remaining reserve stockpile consists of 178 de-mated warheads kept safely in storage.
India recorded a defence spending of US$92.1 billion in 2025, marking an 8.9% growth.
China maintains a much larger nuclear arsenal containing 620 warheads, with 34 of them deployed.
Pakistan possesses an estimated total of 170 warheads in its active nuclear stockpile.

Following the Pokhran-II nuclear tests (1998), India maintained a de-mated nuclear posture.
This meant storing nuclear warheads separately from delivery missiles to prevent any accidental launches.
Any official decision regarding weapon deployment required strict approval from the civilian-led Nuclear Command Authority (NCA).
The recessed deterrent strategy effectively backed the No First Use (NFU) policy by ensuring survivable retaliation without keeping weapons on constant high alert.

India has inducted nuclear-powered ballistic missile submarines, known as SSBNs, to strengthen its sea-based deterrent.
Submarines offer superior stealth because they are much harder to detect than traditional land-based missile silos.
The military now deploys canisterized missiles like Agni-V and Agni-P stored inside sealed tubes.
Canisterized storage allows faster troop movement, longer shelf life, and rapid launch readiness during emergencies.
By keeping a small number of warheads operationally deployed while storing the rest in reserve, India boosts deterrence without dropping its core defensive policies.

The expiry of the New START Treaty has weakened global arms control and reduced transparency between nuclear superpowers.
With no successor treaty regulating the arsenals of the United States and Russia, global uncertainty and the arms race are accelerating.
India faces a complex two-front security environment involving Pakistan's tactical weapons and China's massive long-range arsenal.
China currently maintains around 620 warheads, while Pakistan holds 170 warheads, forcing India to divide its defence resources carefully.
Emerging technologies like artificial intelligence, cyber warfare, and hypersonic weapons leave very little time for crisis decision-making.
Cyberattacks on control networks or AI errors could accidentally escalate local tensions into full-scale conflict.
Modern anti-submarine warfare relies on advanced satellites and underwater sensors, making it harder for submarines to stay hidden.
India must constantly upgrade facilities like INS Varsha and improve submarine stealth to counter these tracking technologies.

India must ensure that all critical nuclear decisions remain firmly under the civilian-led Nuclear Command Authority (NCA).
The Prime Minister-chaired Political Council should continue holding exclusive power to authorize any nuclear weapon employment.
Expanding longer-range submarine-launched ballistic missiles will allow Indian submarines to operate safely far away from enemy waters.
The government should fast-track the induction of the K-4 SLBM with a range of approximately 3,500 km, alongside future K-5 and K-6 missiles.
Securing command networks requires upgrading cyber security, encrypted communications, and space-based early warning systems.
India should build indigenous satellite tracking networks and foolproof command-and-control links to prevent unauthorized access.
Active participation in global arms-control dialogues will help India promote international risk reduction while maintaining credible minimum deterrence.

The SIPRI report highlighting India's 12 operational warheads proves its nuclear triad is maturing rather than turning aggressive.
By upgrading its second-strike power, India successfully safeguards its No First Use policy, protects national sovereignty, and maintains regional stability.
