How Many Nuclear Weapons Does China Have? The Pentagon’s Count
How many nuclear weapons does China have? The Pentagon says the low 600s, on track for over 1,000 by 2030. How the count grew.
How many nuclear weapons does China have? The most authoritative public answer comes from the Pentagon. Its annual report to Congress on China’s military, released on Dec. 23, 2025, says China’s stockpile of nuclear warheads “remained in the low 600s through 2024,” and that the People’s Liberation Army (PLA) “remains on track to have over 1,000 warheads by 2030.” This explainer sets out what the U.S. government has published, how the estimate has changed, and what is driving the growth.
The official U.S. estimate
The 2025 China Military Power Report, issued by the department now called the Department of War, describes the 2024 total as “reflecting a slower rate of production when compared to previous years.” It adds that, despite the slowdown, “the PLA has continued its massive nuclear expansion.”
China does not publish its warhead count. Beijing reaffirms a “No First Use” policy, the report says, and the Pentagon assesses that China “has not demonstrated a willingness” to advance nuclear risk-reduction talks. It notes that China unilaterally suspended a bilateral arms control consultation with the United States in April 2024.
How the estimate has changed
| Report or assessment | Warhead figure | Source |
|---|---|---|
| 2020 Pentagon report | Low 200s, expected to double within a decade | As recounted in the 2025 report |
| 2022 Pentagon report (last time included) | About 1,500 by 2035 if the pace continued | Federation of American Scientists |
| 2025 Pentagon report, stockpile through 2024 | Low 600s | 2025 report |
| 2025 Pentagon report, projection | Over 1,000 by 2030 | 2025 report |

Read together, the figures show a stockpile that roughly tripled from the low 200s in 2020 to the low 600s by the end of 2024, by the Pentagon’s own numbers. Even at 1,000 warheads, China would still hold “several thousand warheads fewer than either the United States or Russia,” according to Matt Korda of the Federation of American Scientists (FAS).
Missiles, silos and launch tests
Warheads need delivery systems, and that is where most of the visible growth has been. The Congressional Research Service (CRS In Focus IF11719, updated July 22, 2026) lists a ground-based missile force with 2,750 short- to intermediate-range ballistic missiles, 400 intercontinental ballistic missiles (ICBMs) and 300 ground-launched cruise missiles. Those are missile counts, not warheads, and many of the shorter-range systems are conventional.
The 2025 Pentagon report says the PLA has “likely loaded more than 100 solid-propellant ICBM missile silos” at its three silo fields with DF-31 class missiles. FAS, which helped reveal those fields in 2021, says they can host up to 320 launchers, and that its own satellite monitoring has not yet found enough evidence to confirm the Pentagon’s loading figure.
Testing has also changed. In September 2024, the PLA Rocket Force launched an unarmed DF-31B ICBM from Hainan Island into the Pacific, its first such launch since 1980, according to the Pentagon. The missile flew about 11,000 kilometers before landing near French Polynesia. China notified the United States and several other countries in advance, but not Japan or the Philippines, the report says.
Doctrine: early warning and low yields
The Pentagon assesses that China is working toward an “early warning counterstrike” posture, which it compares to launch on warning: firing back after detecting an incoming attack but before it lands. The report says China’s early warning satellites can reportedly detect an incoming ICBM within 90 seconds of launch.
The same report says the PLA is “probably pursuing nuclear weapons with yields below 10 kilotons,” and names the DF-26 intermediate-range missile and the H-6N bomber’s air-launched ballistic missile as well suited to carry them. FAS notes this is the first time the report has given a yield figure.
Why it matters
Analysis: Peter’s World interpretation based on the sources cited above.
The headline number, the low 600s, is smaller than many projections had implied, and the Pentagon itself describes slower production. But the slowdown sits inside a much larger build-out: loaded silos, a full-range ICBM test, faster warning and a push for low-yield options. Those are signs of a force designed to be ready, not just to be counted.
That combination changes the arithmetic of deterrence in Asia. A China that can absorb a first strike and respond quickly, and that has smaller weapons for limited use, gives Beijing more options below the level of all-out nuclear war. The Pentagon’s own concern, stated in the report, is that using nuclear forces to deter conventional intervention, while maintaining No First Use, complicates communication during a Taiwan crisis and raises “the risks of unintended escalation.”
The limits matter too. The stockpile estimate is an intelligence judgment, FAS has not independently confirmed the silo loading, and plutonium supply depends on fast breeder reactors the Pentagon says are behind schedule. The 2030 projection is a trend line, not a certainty. With no arms control talks under way, the annual Pentagon report remains the main public yardstick, which is why the next edition will be closely read.
