China’s People’s Liberation Army (PLA) is likely to make a public display of the latest variant of its DF-31 long-range, road-mobile, solid-fuel rocket intercontinental ballistic missile (ICBM) at the high-profile military parade next month to celebrate the 70th anniversary of the end of World War II in Asia, Duowei News, a U.S.-based Chinese political news outlet, reported.


According to the report, the DF-31 is one of the several strategic missiles of the PLA's Second Artillery Corps recently reported by state media along with the DF-5 three-stage ICBM and the latest DF-41 nuclear solid-fueled road-mobile ICBM.

The DF-31 is China's first solid-fuel ICBM and its predecessor, the liquid-fuel DF-22, ceased production in 1985, as the PLA decided to develop a solid-fuel missile to follow what other world powers such as Russia and the U.S. have made.

The original DF-31, which reportedly took 14 years to develop, has a range of 8,000 kilometers. It was also capable of carrying a 700-kg nuclear warhead. The missile was first tested on Aug. 2, 1999, and less than two months later, it was featured in the finale of the Beijing military parade celebrating the 50th anniversary of the founding of the People's Republic of China.

The report said that the DF-31, however, has only a range of 8,000 km, and would only cover the U.S. west coast, barely crossing China's limit for ICBMs.

China's missile program was placed in limbo in the 1990s, when Wo Weihan, a Taiwanese scientist and entrepreneu-- and later, found to be a spy--stole top secret information about the DF-31 from missile expert Guo Wanjun. The information was then passed on to Taiwanese authorities then handed over to the U.S. The two were found guilty of spying and were executed in 2008.

After the incident, China was forced to develop the DF-31A, which made its maiden test flight on Nov. 22, 2002. It officially entered service at the end of 2006. As the primary weapon of the Second Artillery Corps, the DF-31A's range was increased to 11,500 kms, and after the newer DF-41 and JL-2 strategic missiles enter into service.

Twelve DF-31As also appeared in the 2009 National Day military parade in Beijing, the article said.

Aside from China, Russia is the only other country in the world that has developed road-mobile intercontinental missiles, which is equipped with the RT-2PM2 Topol-M and the superior RS-24 Yars. To catch up to Russia, the country began developing a new variant, the DF-31B, which made its maiden test flight on Sept. 25, 2014.

Experts believe that the DF-31B will likely make an appearance at the military parade in Tiananmen Square on Sept. 3.

What's the difference between the DF-31B and DF-41?


Evidence emerges of possible DF-31 ICBM variant
Richard D Fisher Jr, Washington, DC - IHS Jane's Defence Weekly
03 March 2015

Recent testimony by the commander of US Strategic Forces Command and recent images of a Chinese transporter erector launcher (TEL) point to a potential new variant of the solid-fuel DF-31 intercontinental ballistic missile (ICBM).

In testimony given before the US House of Representatives' Armed Services Committee on 26 February, Admiral Cecil D Haney said China is "enhancing existing silo-based ICBMs, conducting flight tests of a new mobile missile and developing a follow-on mobile system capable of carrying multiple warheads".

Previous US statements or reports have mentioned the liquid-fuelled silo-based DF-5A and the solid-fuelled, mobile and multiple independently targetable reentry vehicle (MIRV)-equipped DF-41. Haney's mention of "a follow-on mobile system capable of carrying multiple warheads" may be an indirect reference to the DF-31B.

The Washington Free Beacon reported on 2 October 2014 that a DF-31B was tested on 25 September 2014 but provided no other details.

On 19 February Chinese military web pages showed a new 16-wheel off-road-capable TEL with a four-door cab similar to previous ICBM TELs produced by the Tai'an Company. Partial views of the same TEL appeared on Chinese web pages in mid-2013.

Tai'an has produced tractor-trailer truck-based TELs for the 8,000 km-range DF-31 and 11,200 km-range DF-31A ICBM and a larger 16 wheel off-road TEL for the 11,000-12,000 km-range DF-41.

All of these ICBMs are made by the China Aerospace Science and Technology Corporation (CASC).

The latest TEL differs from that of the DF-41 in that cab rests entirely before the missile tube, whereas the DF-41 missile tube straddles the top of its TEL's cab. Chinese sources suggest this TEL is for the DF-31B.

Whereas the DF-31 and DF-31A have a single pair of aft-mounted mechanisms for elevating the missile to launch position, the newer TEL appears to feature elevating mechanisms both fore and aft the missile tube. This could indicate that the DF-31B has heavier second and third stages.

hopefully we can replace those old DF-5 which can only carry single a 5 MT metropolis eraser warhead, that's crude and inefficient,a single MIRVed DF-41 carry 10 300KT warheads can wipe out 3 metropolis.
It is long rumour DF-5 already carries MIRV but the liquid fill fuel and fixed firing position makes it vulnerable.

Where did you get info that DF-41 carries 10 warheads and each one has yield of 300kt? As far I know Chinese government hasn't made any claims about it.

It's believed so, I just used the 10 300kt warheads configuration to show that a single MIRVed ICBM with much smaller yield is much more efficient than those old MT yield DF-5
