WS-2 WeiShi [Guardian]

The WS-2 GMLRS is featured in the long range, high firing precision, powerful salvo firing force, quick battle reaction, easy operation, convenient maintenance and high security, etc. The rockets can be equipped with different warheads, used in striking large-scale surface targets.

Targets include: military base; airport; port; assembly fleet; important transport hinge; military industrial base; political and economical center; armor troops; artillery and rocket launch position; ground radar station and command control center; and other important military surface targets. Controlling system to adopt the strapdown inertial guidance system composed by low-cost inertial components, controlling the tripath attitude stability of the rocket body and increasing the controlling precision through combining the lateral and normal guidance.

After receiving the campaign mission, the troop should make ready preparation and get together in the battlefield through railway or highway. The WS-2 rockets should be firstly sent out from the battlefield warfare, and hoisted to the transport & loading truck (or directly hoisted to the launch truck), and then be sent to the waiting-position (or directly be sent to the launch position) based on the superior's command. After arriving in the launch position, the GMLRS should be unfolded immediately and conduct rocket launching after prompt preparation. After finishing the mission, the launch truck should retreat to the battlefield or waiting-position. The transport & loading truck should hoist new rockets promptly and prepare for the next round of battle.

The WS-2 GMLRS belongs to the conventional artillery tactical weapon. The GMLRS troop can be provided in the artillery brigade /division as a battalion; can be also provided in the heavy-division as a battalion/battery, directly subjecting to the group army or heavy-division. In the meanwhile, the launch rocket can do battle independently.

Long-range artillery includes the type-96 320mm MRLS, that can reach up to 200km with WS-2 rockets. Reports indicate that ongoing MRLS extensive development includes the Wei Shi series. The 400 mm WS-2 (Wei Shi 2) series has been developed by the Sichuan aerospace industry Corporation (SCaiC). The WS series is being developed to bridge the gap between conventional towed and self-propelled artillery systems and tactical missile systems.

The Sichuan Aerospace Industry Corporation (SCAIC) developed the 400 mm WS-2 (Wei Shi 2) Guided Multiple Rocket Weapon System (GMRWS) carried on the rear of an 8 × 8 cross-country truck chassis, with the powered launcher with two layers each of three launch tubes mounted at the rear. To provide a more stable firing platform, stabilisers are lowered to the ground by remote control. The rockets can be launched from the cab or away from it with the aid of a remote-control system. Some sources have indicated that the overall system was developed for the China National Precision Machinery Import and Export Corporation (CPMIEC). CPMIEC is the overall contractor, with SCAIC responsible for the actual rockets. CEP is quoted as 600 meters, with a maximum flight speed of Mach 5.6 and a range of 200 km.

The rockets can be fitted with the following types of warhead to meet different user requirements:

  • Submunition carrying 540 bomblets with a High-Explosive Anti-Tank (HEAT) warhead that is also highly effective against troops. The HEAT warhead will penetrate up to 85 mm of conventional steel armour and has a lethal radius of 7 meters.
  • Comprehensive effect cluster warhead carrying 61 sub-munitions with each sub-munition warhead containing approximately 200 preformed fragments and a shaped charge. It is claimed that the shaped charge will penetrate 180 mm of conventional steel armour. In addition the warhead also has a incendiary area effect of about 50 meters sq (4 m radius)
  • Fuel air explosive (FAE) called 'Cloud blasting warhead' by the company. This contains 120 kg of FAE and produces a high blast overpressure upon functioning (both duration and peak pressure). The over pressure is quoted as 0.1 MPa (29 psi) at 25 meters and 0.02 MPa (2.9 psi) at 50 meters. No data on pulse duration is provided.
  • High-explosive fragmentation incendiary which is called 'Blast burning warhead' by the company. This contains an undisclosed quantity of high explosive and incendiary pellets in addition to approximately 40,000 spherical steel preformed fragments. The lethal radius is claimed to be 85 meters.
  • High-explosive fragmentation called 'Lethal blasting warhead' by the company. It contains about 38,000 spherical pre-formed fragments and is claimed to have a lethal radius of 85 meters.

China's latest model "Guardian-2D" rocket launcher has a range of up to 400 kilometers. The "Guardian" series multiple rocket launcher system jointly developed by China Precision Machinery Import and Export Corporation and Sichuan Aerospace Industry Corporation previously mainly had three models of "Guardian"-1/1B and "Guardian"-2, and the latest improved model is The world's longest range "Guardian"-2D multiple rocket launcher system.

The "Guardian"-2D rocket launcher system consists of a launch vehicle, a transport loading vehicle, a command vehicle, and a communication vehicle. A combat unit includes a shooting command vehicle, 6-9 rocket launchers, and 6-9 transport loading vehicles. Compared with the early models of the "Guard"-2, the main performance indicators of the "Guard"-2D have been significantly improved.

The first is to increase the range. The range of a rocket launcher is related to the caliber of the rocket. The "Guardian"-2 rocket is 7,150 mm long and has a diameter of 400 mm. The "Guardian"-2D rocket is 8,100 mm long and has a projectile diameter of 425 mm. In terms of range, the "Guardian"-2 has a maximum range of 200 kilometers, while the "Guardian"-2D has a maximum range of 400 kilometers. In terms of its caliber and range, the "Guardian"-2D can be called China's largest caliber rocket launcher system with the longest range in the world.

The second is accuracy improvement. In order to ensure the necessary shooting accuracy, compared with the early models of the “Guardian”-2, the “Guardian”-2D adopts simple guidance and ballistic correction measures, thereby effectively improving the shooting accuracy. It is said that the "Guardian"-2D uses a strapdown inertial navigation system composed of low-cost inertial devices to improve control accuracy. At the end, advanced technologies such as global satellite positioning or laser trajectory correction can even be used. When the range is 400 kilometers , The shooting accuracy reaches the level of less than 600 meters.

Multiple types of warheads are another highlight of the "Guardian"-2D rocket launcher. In addition to traditional high-explosive bombs, more than six different types of warheads can be used according to different strategic and tactical requirements. Among them , the accuracy of the two-way terminal-sensitive submunition and the homing bomb attack vehicle is very high, and it is said that it can directly hit the target. There is even a kind of drone that can carry three small drones in the rocket. This is a drone that drops suicide ammunition after the rocket reaches the target and can search for radar signals on the ground to perform suicide attacks.

In addition, the "Guardian"-2D abandoned the previous cylindrical launch box and adopted an integrated six-pack launch/storage box. This is also the most mainstream design style of the world's rocket launcher box because the rockets are loaded in a sealed box. , Storage and launch are very convenient. Moreover, the equipped ammunition carrier is equipped with an automatic loading system, which can be quickly reloaded after a salvo is completed. Its launch vehicle uses a new 8x8 high-mobility wheeled off-road vehicle as the carrier chassis, which has good maneuverability.

For rocket launchers, improving the range, strike accuracy, and damage power has become a major development trend. The "Guardian"-2D rocket launcher system has a series of advantages such as long range, powerful salvo, fast combat response, simple use and maintenance, etc., to a certain extent, it can almost replace expensive short-range missiles to attack enemy military bases and cluster armors. Targets such as troops, airports, and ports.
