Unlike China's older silo-based strategic missiles, which would have been relatively easy to destroy before launch, the DF-31 can be concealed on the back of a lorry.
To increase survivability and reduce launch preparation time, the solid propellant DF-31 and DF-31A road-mobile ICBMs have been developed and are being fielded.
It is the only test facility to be outfitted with a DF-5 series silo for trials launches, and has been cited in the open press as the launch site for DF-31 and DF-31A trials.
Research of Effective Neutron Multiplication Factor and Neutron Flux Distribution for Accelerator Driven Sub-Critical System on DF-3 Facility;
Launch sites located near Xixia, once thought to serve the 813th Brigade at Nanyang, may support a separate DF-31 or DF-31A unit.
China also developed an improved model DF-31A with extended range of 10,000km, improved accuracy and multiple independently-targeted re-entry vehicle (MIRV) capability.
