SIPRI: India Surpasses Pakistan in Nuclear Arsenal, Advances in Missile Technology
Canisterized missile systems give India a strategic edge as regional and global nuclear tensions escalate
The latest report from the Stockholm International Peace Research Institute (SIPRI) reveals that India now possesses more nuclear weapons than Pakistan, underscoring a significant shift in the regional nuclear balance. According to SIPRI’s 2025 data, India’s nuclear arsenal has grown from 172 warheads in 2024 to 180, surpassing Pakistan’s count and reflecting New Delhi’s broader investments in missile modernization.
Strategic Gains in Missile Technology
One of the most notable developments cited in the report is India’s progress in ‘canisterized’ nuclear-capable missile systems.
- These missiles are pre-loaded with nuclear warheads, making them operational even during peacetime.
- The canister design enhances safety, storage, and mobility, while ensuring quick launch capability during crises.
- In the future, these systems may be able to carry Multiple Independently Targetable Reentry Vehicles (MIRVs) — multiple nuclear warheads on a single missile, aimed at different targets.
Such advancements significantly improve India’s second-strike capability, a cornerstone of credible nuclear deterrence.
Regional Dynamics and Growing Tensions
SIPRI’s report warns that the nuclear rivalry between India and Pakistan remains a cause for concern, particularly amid persistent regional tensions.
- India’s expanding arsenal and technological superiority could alter strategic calculations in South Asia.
- The report also highlights China’s rapidly growing nuclear stockpile, suggesting that the wider Asia-Pacific may be entering a new era of nuclear competition.
Global Implications
SIPRI cautions that the simultaneous modernization of nuclear forces by India, Pakistan, and China could contribute to a global resurgence in the nuclear arms race.
- Such developments raise alarms over strategic stability, particularly in regions where conflict thresholds are already low.
- The growing role of advanced delivery systems, such as canisterized and MIRV-equipped missiles, further complicates efforts at arms control and confidence-building.
As India continues to enhance its nuclear posture, its evolving strategy will play a critical role in shaping not just regional deterrence architectures, but also global non-proliferation dialogues in the years ahead.
