A Growing Stockpile
The 2020 China Military Power Report assessed that China had approximately 200 nuclear weapons in total and that it had the capability to double that number over the next decade.“The PRC has commenced building at least three solid-fueled ICBM [intercontinental ballistic missles] silo fields, which will cumulatively contain hundreds of new ICBM silos,” the report reads.
The report also states that China’s new nuclear energy efforts could cross-function as a means of developing the extra plutonium needed for the desired nuclear weapons buildup.
Advancing Nuclear Technologies
China isn’t only expanding its nuclear capacity, however. It’s also evolving its capabilities through military modernization, developing disruptive technologies such as hypersonic cruise missiles, according to the report.“The PRC probably intends to develop new nuclear warheads and delivery platforms that at least equal the effectiveness, reliability, and/or survivability of some of the warheads and delivery platforms currently under development by the United States and/or Russia,” the report reads.
“The PRC is developing new intercontinental ballistic missiles (ICBMs) that will significantly improve its nuclear-capable missile forces and will require increased nuclear warhead production, partially due to the incorporation of multiple independently targetable reentry vehicle (MIRV) capabilities,” the report reads.
MIRVs are a type of missile payload consisting of multiple warheads launched from a single missile, each of which can be independently aimed at its own unique target once detached from the rocket that brought it to orbit.
An Evolving Posture
The report outlines that China maintains a “no first use” policy, despite its ongoing buildup of nuclear weapons. The policy states that China will never be the first to use nuclear weapons in a conflict, nor will it use or threaten to use them against non-nuclear states.As such, China’s nuclear policies prioritize the ability of its forces to survive an initial nuclear strike from an adversary.
“The PRC’s nuclear weapons policy currently prioritizes the maintenance of a nuclear force able to survive a first strike and respond with sufficient strength to conduct multiple rounds of counterstrike, deterring an adversary with the threat of unacceptable damage to its military capability, population, and economy,” the report reads.
The report also notes that the PLA is implementing a so-called launch-on-warning posture.
This means that China is placing some of its nuclear units on an alert, so that if they receive a warning that a nuclear weapon has been launched against them, they'll immediately retaliate with their own nuclear forces without waiting to verify that the attack is real by waiting for a detonation.
Nuclear units in the United States and Russia maintain similar postures.
The report also states that PLA planners would likely seek to avoid a protracted series of nuclear exchanges against a superior adversary, although PLA documents from 2012 explored the ramifications of so-called “small-yield” nuclear weapons that could be used in a more precise manner.
“Such discussions provide the doctrinal basis for limited nuclear employment on the battlefield, suggesting PRC nuclear thinkers could be reconsidering their long-standing view that nuclear war is uncontrollable,” the report reads.
