New Delhi: Federation of American Scientists reports that India may have produced enough weapons-grade plutonium to support up to 225 nuclear warheads, although analysts estimate the country’s current arsenal stands at around 190 warheads in 2026. The findings highlight India’s growing strategic deterrence capabilities and ongoing modernization of its nuclear forces.
Details of Federation of American Scientists Report
The Federation of American Scientists (FAS), a US-based non-profit research organization, published its latest assessment of India’s nuclear forces in 2026.

The report estimates that India currently possesses around 190 nuclear warheads, including operational warheads and additional units reserved for future missile systems. Analysts believe India’s stockpile could grow further as new delivery systems and missile platforms enter service.
Federation of American Scientists Report: India’s Estimated Nuclear Arsenal In 2026
According to the FAS study, India’s nuclear force includes air-based, land-based, and sea-based delivery systems. The report estimates:
Air-Based Nuclear Capability
The Indian Air Force maintains aircraft capable of delivering nuclear weapons. These include:
- Mirage 2000H aircraft
- Jaguar IS aircraft
Together, they are estimated to support around 48 nuclear warheads.
Land-Based Missile Force
Land-based ballistic missiles form the backbone of India’s nuclear deterrent. These include:
- Prithvi-II
- Agni-I
- Agni-II
- Agni-III
- Agni-IV
- Agni-V
The report estimates more than 100 warheads are assigned to land-based missile systems.
Sea-Based Nuclear Deterrent
India’s sea-based deterrent is operated through nuclear-capable submarine-launched ballistic missiles. Current systems include:
- K-15 (B-05) missile
- K-4 missile (under development and deployment process)
Sea-based systems are considered crucial because they provide a second-strike capability during a conflict.
Federation of American Scientists Report: How Much Plutonium Does India Have
The report states that India may have produced approximately 730 kilograms of weapons-grade plutonium. Based on standard estimates of plutonium required per warhead, this quantity could theoretically support up to 225 nuclear weapons. However, experts caution that actual warhead numbers depend on weapon design, reserve stock requirements, and operational planning.
Sources Of India’s Weapons-Grade Plutonium
Dhruva Reactor
The Dhruva reactor at the Bhabha Atomic Research Centre (BARC) has long been considered a major source of India’s weapons-grade plutonium production.
CIRUS Reactor Legacy
The CIRUS reactor also contributed to India’s plutonium production before it was permanently shut down.
Prototype Fast Breeder Reactor (PFBR)
The Prototype Fast Breeder Reactor (PFBR) at Kalpakkam achieved first criticality in 2026.
Experts believe the reactor could significantly increase India’s plutonium production capacity in the coming years. If operated efficiently, the PFBR may be capable of producing enough plutonium annually for dozens of additional warheads.
Federation of American Scientists Report: India’s Nuclear Modernization Program
The FAS report notes that India continues to modernize its nuclear arsenal. Several older systems are being upgraded or replaced with more advanced missile technologies.
New Missile Systems Under Development
The report indicates that additional strategic systems are nearing completion and could become operational within the next few years. These developments are expected to improve range, survivability, and deterrence effectiveness.
Expansion Of Strategic Forces
India currently operates a nuclear triad consisting of:
- Aircraft-based delivery systems
- Land-based ballistic missiles
- Sea-based nuclear missiles
The nuclear triad is designed to ensure a credible minimum deterrent under all circumstances.
Why The Estimates Matter
India does not officially publish the size of its nuclear weapons stockpile. As a result, independent organizations rely on:
- Satellite imagery
- Government statements
- Open-source intelligence
- Scientific and technical assessments
Because of these limitations, all published estimates carry a degree of uncertainty.
Global Strategic Implications
India’s growing nuclear capability reflects its focus on maintaining a credible deterrent in a complex regional security environment. Analysts believe future growth in plutonium production and missile development could further strengthen India’s strategic posture.
At the same time, experts emphasize that stockpile estimates should be viewed cautiously because official figures remain undisclosed.
FAQs
The report estimates that India’s available weapons-grade plutonium could theoretically support up to 225 nuclear warheads, depending on weapon design and production choices.
The Federation of American Scientists estimates that India has approximately 190 nuclear warheads in 2026, including operational and reserve warheads.
The PFBR is an advanced nuclear reactor located at Kalpakkam. Experts believe it could significantly increase India’s future plutonium production capacity.
