China has had a nuclear missile capable of reaching the United States since the early 1980s, the Dongfeng-5, but it has issues that have recently limited its effectiveness as a deterrent. Its liquid fuel propellant means that it must undergo a lengthy fueling process before it can be launched, and its lack of mobility renders its silos vulnerable to strikes by increasingly accurate munitions. Those threats to its survivability reduce its value as a minimum credible deterrence. China needed to upgrade to a more survivable missile inventory given its historically smaller nuclear arsenal and no-first-use doctrine. Development of the Dongfeng-41 — a solid-fuel nuclear-capable road-mobile system — is thought to have begun in the late 1980s, but the program was subject to multiple delays and pauses along the way. Other updates to China's strategic arsenal were introduced in the meantime.
