Description	The Dongfeng-31 (DF-31), DF-31A, and DF-31AG are a series of Chinese intercontinental ballistic missiles (ICBMs), representing advancements in China’s nuclear strike capabilities.The DF-31, the initial variant, is a solid-fueled, three-stage ICBM with an estimated range of 8,000-11,000 km, capable of carrying a single nuclear warhead. The DF-31A is an improved version with a longer range, estimated at over 11,000 km, and is believed to be capable of carrying multiple independently targetable reentry vehicles (MIRVs), allowing it to strike multiple targets with a single missile. This significantly enhances its effectiveness and complicates adversary defense strategies. The DF-31AG is the most recent variant, and while details are less publicly available, it is believed to be a further development of the DF-31A. It is speculated to have improved mobility, possibly through road-mobile launcher upgrades, and potentially further refinements to its MIRV capabilities or other technological enhancements. All three are road-mobile, enhancing their survivability by making them harder to locate and target compared to silo-based missiles. The development of these ICBMs underscores China’s commitment to maintaining a credible nuclear deterrent. These missiles are considered a cornerstone of China’s strategic nuclear forces, providing a land-based component to its nuclear triad. The DF-31 series’ mobility and MIRV capability are seen as crucial for ensuring a retaliatory strike capability. These missiles are solid-fueled, enabling quicker launch times compared to liquid-fueled ICBMs.They represent a significant advancement in China’s missile technology. The DF-31 series plays a crucial role in China’s nuclear strategy. Their deployment has implications for global security dynamics. They are a symbol of China’s growing military power. The continuous development of these missiles highlights the ongoing arms race. The DF-31, DF-31A, and DF-31AG are vital components of China’s nuclear arsenal.
