Evidence emerges of possible DF-31 ICBM variant

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.

ANALYSIS
Assuming the DF-31B did emerge in mid-2013, it is possible that this ICBM has succeeded the DF-31A on the CASC production line. A missile testing campaign usually precedes deployment to units of the Second Artillery Corp, the main nuclear and non-nuclear missile strike force of China's People's Liberation Army (PLA).
The PLA has shown it can share warhead technologies among multiple missile types, such as the terminally guided warhead that arms the DF-21C MRBM and the DF-15B SRBM. MIRV technology reportedly tested on the DF-41 in December 2014 may now equip a new DF-31 variant.
