WS 35: 150 km long

The Weishi (WS; Chinese: 卫士; literally: "Guardian") family of the multiple rocket launcher systems were mainly developed by Sichuan Aerospace Industry Corporation (SCAIC, also known as Base 062) in Chengdu, Sichuan Province. The Weishi series rocket systems include the 302mm WS-1 (100 km range), the improved 302mm WS-1B (180 km range), the 122mm WS-1E (40 km), the 400mm WS-2 (200 km range), as well as many other models. The WS-1 series weapon system did not enter PLA service and has order from Thailand. The WS-2 may finally see PLA service in the future. It's worth noticing that although sharing the same name, there are other developers for different models of Weishi series multiple rocket launchers (MRL) other than the primary developer SCAIC.
