China’s Expanding Nuclear Arsenal: Current Status and Strategic Shift
As of early 2026, China has expanded its nuclear warhead stockpile to an estimated 620 units, according to a report from the Stockholm International Peace Research Institute (SIPRI). This increase from 600 warheads the previous year highlights a broader trend of modernization, with Beijing potentially moving toward a more active deployment posture for its nuclear forces.
The Scale of China’s Nuclear Growth
The latest SIPRI yearbook data indicates that China added 20 warheads to its arsenal over the last year. Experts anticipate this growth will continue throughout the coming decade. Beyond the raw numbers, the composition of China’s forces is undergoing a significant transformation. The report identifies approximately 775 land-based missile silos as of January 2026. This infrastructure development suggests that China’s intercontinental ballistic missile (ICBM) inventory could reach parity with those of the United States and Russia by the end of the decade.
Operational Changes in Deployment
A critical shift noted by SIPRI is the potential change in how these weapons are handled during peacetime. Traditionally, China has kept the vast majority of its warheads in storage, separated from their delivery systems. However, the report suggests that Beijing may now be deploying warheads on missiles within a few mobile battalions during military exercises.
SIPRI estimates that the number of nuclear warheads deployed with operational forces rose to approximately 34 in January 2026, up from 24 in 2025. Furthermore, citing US government sources, the report suggests that warheads may have been loaded into missiles housed at three newly constructed silo fields and potentially aboard nuclear-powered ballistic missile submarines currently conducting near-continuous deterrence patrols.
Disarmament Commitments Under Pressure
The SIPRI report warns that major nuclear powers are increasingly distancing themselves from established disarmament commitments. This trend is framed against a backdrop of global modernization efforts, where China’s rapid expansion is a focal point. While the US and Russia have long maintained the world’s largest arsenals, China’s current trajectory represents a departure from its historical policy of maintaining a “minimum” deterrent.

Frequently Asked Questions
Are China’s warheads always ready to launch?
According to SIPRI, the vast majority remain in storage. However, evidence suggests a shift toward integrating warheads with mobile launchers during exercises and potentially within new silo fields.
How does China’s arsenal compare to the US and Russia?
While China currently holds fewer warheads than the United States or Russia, its rapid development of ICBM silos suggests a strategic intent to match the inventory levels of these two nations by the end of the decade.
What is the primary driver of this growth?
The SIPRI report characterizes these developments as a significant modernization and expansion effort, signaling that China is moving away from previous limitations on its nuclear stockpile size and operational readiness.
