The modernization of China’s nuclear arsenal has both accelerated and expanded in recent years. In this issue of the Nuclear Notebook, we estimate that China now possesses approximately 600 nuclear warheads, with more in production to arm future delivery systems. China is believed to have the fastest-growing nuclear arsenal among the nine nuclear-armed states; it is the only Party to the Treaty on the Non-Proliferation of Nuclear Weapons that is significantly increasing its nuclear arsenal.

As of January 2025, we estimate that the US Department of Defense maintained an estimated stockpile of approximately 3,700 nuclear warheads for delivery by ballistic missiles and aircraft. Most of the warheads in the stockpile are not deployed but rather stored for potential upload onto missiles and aircraft as necessary.
