Weishi rockets

The Weishi (WS; Chinese: 卫士; lit. 'Guardian') family of multiple rocket launcher systems were mainly developed by Sichuan Academy of Aerospace Technology (SAAT, also known as Base 062) in the central province of Sichuan, China at Chengdu city. The systems include the 302 mm (11.9 in) WS-1 (100 km (62 mi; 54 nmi)), the improved 302 mm (11.9 in) WS-1B (180 km (110 mi; 97 nmi)), the 122 mm (4.8 in) WS-1E (40 km (25 mi; 22 nmi)), the 400 mm (16 in) WS-2 (200 km (120 mi; 110 nmi)), as well as many other models. The Weishi series rocket system did not enter PLA service, but was exported to several countries.

In the 1980s, the People's Liberation Army Ground Force planned to procure long-range multiple rocket launchers and explored options from several Chinese military corporations. Four companies bid in the competition:

In the end, the AR-1 multiple rocket launcher system was chosen by the People's Liberation Army Ground Force, which received designation PHL-03. After the competition, these companies started to export their products. The China Aerospace Science and Industry Corporation (CASIC) did not participate in the bidding process due to time constraints, but CASIC revealed its first MLRS design, SY-400, in the Zhuhai Airshow 2008.

Unlike AR-1 and A-100, the WS-1 and WM-80 are not guided rockets, resulting in their poor accuracy at their maximum range. The accuracy problem was one of the reasons behind WS-1's failure in securing the bid. After receiving feedback, the Sichuan 7th Academy began to improve the WS-1 rockets, resulting in WS-1B and other Weishi rockets with guided ammo. Weishi rockets are one of the most exported Chinese rocket systems due to their affordability.

Turkey was the first customer of the WS-1 rocket, buying WS-1B in 1996. Turkey soon reverse-engineered the WS-1B and made a copy called TR-300.

SCAIC began to develop an unguided large-calibre multiple launch rocket system for the PLA ground forces in the late 1980s. The resulting Weishi-1 (WS-1) 302 mm, 4-tube multiple rocket system was first tested in 1990. However, the weapon system failed to impress the PLA, and no production order was received. The ground equipment of the WS-1 comprises: a rocket launch truck, a transport and loading truck and a firing command truck.

A WS-1 rocket battalion is equipped with:

The Syrian M-302 (also known as the Khaibar-1) is based on the WS-1 rocket.
