The 2024 DOD China Military Power Report
The Department of Defense has finally released the 2024 version of the China Military Power Report. We will provide additional analysis of the Chinese arsenal in early 2025 but offer these observations for now:
The report estimates that China, as of mid-2024, had more than 600 nuclear warheads in its stockpile, an increase of roughly 100 warheads compared with the estimate for 2023 and about 400 warheads since 2019. As we have stated for several years, this increase is unprecedented for China and contradicts China’s obligations under the Nuclear Nonproliferation Treaty. DOD assesses that the Chinese nuclear buildup “almost certainly is due to the PRC’s broader and longer-term perceptions of progressively increased U.S.-PRC strategic competition.”
The breakdown of the DOD estimate comes with considerable uncertainty. It appears to assume that sufficient warheads have been produced to arm many – perhaps up to one third – of the silos in the three new ICBM silo fields in northern China. Different assumptions about how those silos will be armed greatly influence warhead projections:
Matching the warhead estimate with the known force structure also depends on how many of the new liquid-fuel silos under construction in the mountains of central/southeastern China are operational, and how many of missiles carry multiple warheads. Other variables are how many warheads are assigned to the DF-26 IRBM launchers (probably not all of them), how many of the six SSBNs have been upgraded to the JL-3 SLBM and whether it is assigned multiple warheads, and how many DF-41 ICBM launchers are operational and how many warheads each missile is assigned.
As in previously years, the DOD report misleadingly describes the Chinese warheads as “operational.” This gives the false impression that they’re all deployed like Russia and U.S. nuclear warheads on their operational forces and has already created confusion in the public debate by causing some to compare all Chinese warheads with the portion of US warheads that are deployed. What DOD calls China’s “operational” warheads is equivalent to DOD’s entire nuclear warhead stockpile, whether deployed, operational, or reserve.
Except for perhaps a small number, the vast majority of Chinese warheads are thought to be in storage and not deployed on the launchers. This situation may be changing with a higher readiness level and emerging launch-on-warning capability.
The report repeats earlier projections that China might have over 1,000 warheads by 2030 but does not mention previous projections of 1,500 warheads by 2035. But this expansion requires additional plutonium production. The report confirms that China “has not produced large quantities of plutonium for its weapons program since the early 1990s” and anticipates that it “probably will need to begin producing new plutonium this decade to meet the needs of its expanding nuclear stockpile.”
ICBMs
The report lists 550 ICBM (Intercontinental-Range Ballistic Missile) launchers with 400 ICBMs, an increase of 50 launcher and 50 missiles compared with last year’s report. That is more ICBM launchers than the United States has, although far from all the Chinese silos are armed.
It is unclear what operational status a missile must have to be included in the count or whether 400 is simply the total number of missile available for the launchers. If it means operational (which I don’t think is the case), then 400 ICBMs would imply a significant number of the new silos loaded.
The report includes a map that appears to match previous FAS analysis of the three silo fields:
The report states that the three ICBM fields were probably completed in 2022 and that PLARF has loaded “at least some” ICBMs into the silos. The report says China “probably continues to arm” the silo fields.
For now, the new silo fields appear intended for the solid-fuel DF-31A. The DOD report identifies a new version of the DF-31 (CSS-10 Mod 3), which is probably the version intended for the silos.
The ICBM estimate appears to come with several caveats. One is that the number of ICBM launchers is not the same as the number of operational ICBMs. A silo launcher appears to be counted when construction is completed, whether it is operational with missile or not. To get to 550 launchers, it is necessary to count everything, including all the 320 silos in the three new northern silo fields as well as all the silos under construction in the southeastern mountains.
The report says the silo construction in the central/southeastern part of China will probably result in about 50 silos there, matching estimates made by FAS and others. The report confirms that those new silos are intended for DF-5 liquid-fuel missiles and appears to suggest that at least two brigades with the new silos are intended for the new multi-megaton DF-5C that it says China is now fielding.
The report does not say how many of the new DF-5 silos – if any – have been loaded with missiles.
The new DF-41 ICBM is not said to be deployed in silos but so far only as a road-mobile system in a few brigades. But the DOD report says China might pursue silo and rail deployments for the missile in the future.
The new DF-27 is described as dual-capable and while capable of shorter ICBM ranges mainly be intended for conventional IRBM missions.
IRBMs and MRBMs
The report lists 250 IRBM (Intermediate-Range Ballistic Missile) launchers with 500 missiles, the same as in 2023. This force apparently consists entirely of the DF-26, of which the report identifies three versions. Previously an anti-ship version was identified in addition to the basic version, so it is unclear if the first two versions are used to differentiate between the conventional and nuclear versions. Regardless, the DF-26 is replacing the DF-21 MRBM (Medium-Range Ballistic Missile) and the report says there are no longer any brigades with “dual nuclear-conventional capable DF-21Cs” (which is odd because the C was the conventional and the A was the nuclear).
The DF-17 MRBM maneuverable glide vehicle is described as conventional.
SSBNs
The report says that China continues to operate six Jin-class Type 094 SSBNs (nuclear powered ballistic missiles submarines) equipped with either the JL-2 or the 10,000-km range JL-3 SLBM (Sea-Launched Ballistic Missile). Despite the longer range of the JL-3 SLBM, it is not capable of targeting the Continental United States from the South China Sea. A submarine would have to deploy up into the shallow Bohai Sea to be able to target part of CONUS.
The DOD report says the six SSBNs “are conducting at sea deterrent patrols.” In the U.S. Navy, that means the missiles are armed with nuclear warheads, but the DOD report does not explicitly say this is the case for China.
The report says the SSBNs are “representing the PRC’s first viable sea-based nuclear deterrent,” and says China “has the capacity to maintain a constant at sea deterrent presence.” More Jin-class SSBNs apparently are under construction.
The next-generation Type 096 apparently is not yet under construction. It is said it will get a new longer-range missile, although it is unclear if that is older language that used to refer to the JL-3. The report says the Type 096 SSBN “probably is intended to field MIRVed SLBMs,” indicating that the SLBMs on the current Jin-class are not.
Bombers
The report repeats previous statements that China is fielding a nuclear version of the H-6 medium-range bomber. The nuclear version H-6N is capable of carrying a large air-launched ballistic missile that “may be” nuclear capable. Although China is often said to have a Triad, the air-leg is nascent and still only includes one brigade that is developing tactics and procedures for the PLAAF nuclear mission.
As mentioned above, we will provide additional analysis of the DOD report and Chinese nuclear forces early in the new year. More information: The Nuclear Information Project
The Federation of American Scientists’ work on nuclear transparency would not be possible without generous support from the Carnegie Corporation of New York, Longview Philanthropy, the Jubitz Foundation, the New-Land Foundation, Ploughshares, the Prospect Hill Foundation, and individual donors.
The Department of Defense has finally released the 2024 version of the China Military Power Report.
With tensions and aggressive rhetoric on the rise, the next administration needs to prioritize and reaffirm the necessity of regular communication with China on military and nuclear weapons issues to reduce the risk of misunderstandings.
Congress should ensure that no amendments dictating the size of the ICBM force are included in future NDAAs.
In early November 2024, the United States released a report describing the fourth revision to its nuclear employment strategy since the end of the Cold War and the third since 2013.
