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: • DZ-88B firing command truck (4 men): 1; • MF-4 rocket launch truck (3 men): 6~9; • QY-88 transport and loading truck (3 men): 6~9; • High-altitude meteorological radar (3 men): 1; • Rockets per launch truck: 40~60; The Syrian
M-302 (also known as the
Khaibar-1) is based on the WS-1 rocket.
WS-1B SCAIC continued the WS-1 development in the 1990s and introduced the improved WS-1B in the late 1990s. The WS-1B mainly targeted foreign customers and was actively marketed by Beijing-based China National Precision Machinery Corporation (CPMIEC). Compared to the WS-1, the WS-1B features an increased range of 180 km. A WS-1B rocket battalion is equipped with: • DZ-4B firing command truck (5 men): 1; • HF-4B rocket launch truck (3 men): 6~9; • QY-4B transport and loading truck (3 men): 6~9; • Type 702 high-altitude meteorological radar (3 men): 1; • Rockets per launch truck: 40~60;
WS-1E The WS-1E is the 122 mm multiple rocket system developed by SCAIC as a successor to the PLA's current Type 81 122 mm rocket system. It is similar to the Type 90 122 mm rocket system and did not enter production. A WS-1E rocket battalion is equipped with: • DZ-88B firing command truck (5 men): 1; • MF-40 rocket launch truck (3 men): 6; • Rockets per launch truck: 120~160;
WS-1F Little is known except that range reaches . is based on Chinese WS-1B (Wei Shi; Guardian), with some modifications on the design with launcher very similar to the WS-1B's launcher. In Turkish land forces service, the 302 mm T-300 Kasirga MBRL system provides long range fire support. The T-300 Kasirga MBRLS consists of two key parts: The launcher system (T-300) and the rocket, TR-300. The T-300 MBRL is based on the German MAN (6×6) 26.372 10t cross-country truck chassis. Combat weight, complete with four rockets, is 23t. This MAN (6×6) also serves as
T-122 launch platform for Turkish land forces command. F-302T, the launcher vehicle's cabin windows are provided with shutters which are lowered before the rockets are launched. • TR300S:Unguided, range: 36–65 km • TR300E:Unguided, range: 65–100 km • TR300K:Guided, range: 30–120 km == WS-2 ==
