The WS21200 is a large transporter erector launcher built and developed in the People's Republic of China.

The size of the WS21200 allows it to carry ICBMs, however, the technological limitations of Pakistan has forced the WS21200 to mount medium-range ballistic missiles such as the Shaheen-III.

[2][3] The Wanshan WS21200 is a Chinese/Pakistani 16x16 road-mobile TEL with a payload capacity of 80 tons thanks to the Cummins KTTA19-C700 turbocharged diesel engine.

[1] Similar to its North Korean sister counterpart, the WS51200, the WS21200 is used primarily by the Pakistani Air Force Strategic Command, which aims at improving Islamabad's nuclear first and second strike capabilities.

[4] Although it could theoretically mount an ICBM, Pakistan's limited resources in nuclear and ballistic missile technology and capability, means that the full potential for the WS21200 is regulated in carrying the Shaheen-III and Shaheen-II MRBMs.
