These trucks behave essentially like conventional transporter erector launchers and as such, are used primarily to offer Beijing second strike nuclear capabilities; bolstering China's ballistic missile capabilities.

This increased size allows the HY4330 to tow the much larger DF-31A road-mobile intercontinental ballistic missile.

[3][4] Due to this, the Hanyang Special Purpose Vehicle Institute developed this truck specifically for this role.

The HY4330 became operational in 2007 and is implemented specifically to the Second Artillery Corps of the People's Liberation Army Rocket Force.

As the HY4330 and the smaller HY4260 is powered by the Deutz BF12L513C turbocharged diesel engine, the HY4330 could carry a maximum payload of 60 tons whilst maintaining a higher speed with a maximum travel range of 1000km, vastly improving its mobility and complicating detection.
