China has conducted test flight of new DF-31B intercontinental ballistic missile.
China’s military has conducted the first flight test of a new variant of one of its DF-31 road-mobile intercontinental ballistic missiles. The test of the new DF-31B missile was conducted September 25,2014, from a missile test range in central China.

The DF-31B is an upgraded version of the DF-31A and the launch was at least the second time the PLA's Second Artillery Corps had tested a DF-31 missile in the past three months. In late July, the PLA conducted a flight test of a DF-31A in what was the fourth known flight test of that missile in two years.

The new DF-31B is the latest addition in the Chinese intercontinental ballistic missile arsenal that includes older silo-based missiles and five other road-mobile missiles. They include the long-range DF-31, DF-31A and DF-41 ICBMs, intermediate-range DF-26Cs, and medium-range DF-21s—a missile the Chinese have developed into a dual, nuclear-conventional weapon that includes an anti-ship variant. A DF-21 variant also is believed to be used as China’s anti-satellite missile system.

The DF-31 (CSS-9) is an intercontinental-range, road/rail-mobile, three-stage solid propellant ballistic missile. Development on the missile began in 1970 alongside the missile’s submarine based counterpart, the JL-2.

The DF-31 is believed to have a length of 13.0 m, a diameter of 2.25 m, and a launch weight of 42,000 kg. Conflicting reports have placed the maximum range of this missile between 8,000 and 11,700 km.

China also developed an improved version of the DF-31 called the DF-31A. Production presumably began in the late-to-mid 1990s, or latter stages of the original missile’s development. This version uses a significantly longer third-stage motor to bring the missile to a total length of 18.4m and a maximum range beyond 10,000 km. Some reports place the range of the DF-31A between 10,000 and 14,000 km
