Sanyang HY4330 Tractor Truck

The Hanyang HY4330 is an 8×8 tractor truck. It tows special semi-trailer with DF-31A (Western designation CSS-10 Mod 2) road-mobile intercontinental ballistic missile. This tractor truck has been developed by Hanyang Special Purpose Vehicle institute for this sole role. It has been produced by Hanyang Special Vehicle Works. It became a successor to an older Hanyang HY4301 8×8 vehicle, that towed a baseline DF-31 intercontinental ballistic missile. The HY4330 alongside with the new missile was adopted in 2007 and is used by Second Artillery Corps, that are de facto strategic missile forces of Chinese army. It seems that only a small number of these specialized tractor trucks have been built.
The HY4330 tows semi-trailer with a missile that weights around 60 000 kg.
Vehicle has a four-door crew cab, that accommodates driver and launch crew of the missile.
Vehicle is powered by a Deutz BF12L513C turbocharged diesel engine, developing 540 hp. It seems that this vehicle has a selectable 8×4 or 8×8 configuration. Even though tractor truck and associated semi-trailer have some degree cross-country mobility, the HY4330 is mainly intended to operate on paved roads.
