Pentagon spokesperson Cynthia Smith said China completed a test of the DF-31B on Sept. 25 and that the new missile system is probably a multi-warhead version of the DF-31 missile. It is designed specifically for travel on rugged terrain or other difficult road conditions, a Chinese military website stated. The state-run Russian newspaper said that China is currently the only nation except Russia to develop a land-based ICBM.
The United States devoted most of its resources to the development of submarine-launched ballistic missiles after the decommissioning of the LGM-118 Peacekeeper in 2005. The Russian-language newspaper said the Soviet Union developed various road-mobile ICBMs including the SS-20, the SS-24 and the Topol. With a range of 5,500 kilometers, the SS-20 was an extremely dangerous threat to the United States and its Western allies.
With such mobility, it will be very difficult for US satellites to locate the Topol missiles on the ground. China has decided to develop road-mobile launchers as well because it has similar terrain to Russia. The newspaper said the DF-31B is China’s Topol. The attacking range of the Topol is 10,000 kilometers, while the details of the DF-31B are still unknown. The state-run Global Times however, stated that the attacking range of the DF-41 is estimated to be around 14,000 km.
