Kung Feng 4

In the 1960s, Taiwan began to develop the "Workerbee"-4 multiple rocket launcher. The directional tube of the "Workerbee"-4 multiple rocket launcher has a caliber of 126 mm (inner diameter) and a maximum range of 10.5 kilometers. Its chassis is based on the United States. Produce M-113A1 or LVPT-5 armored vehicle chassis. After the "Workerbee"-4 multiple rocket launcher was successfully developed, Taiwan's "Chinese Academy of Sciences" began to consider the development of a longer range multiple rocket launcher. The Kung Feng 4 is a self-developed multi-barrel rocket launcher developed by Taiwan’s "Zhongshan Academy of Sciences". It was developed in the early 1970s and was equipped with troops in 1976. It is Taiwan’s first self-built rocket launcher. This gun is divided into two types, the towed "worker bee" 3 and the self-propelled "worker bee" 4. The towed "worker bee" 3 is mounted on a two-wheeled trailer and is towed by a 2.5-ton truck and is mainly equipped with army units. The self-propelled "worker bee" 4 can be installed on the Marine Corps amphibious landing armored vehicle LVT-P5, on the Army’s armored transport vehicle M113, or on a truck. At present, the equipment is only found in the artillery directly under the Taiwan Army Corps. The advantage of the Worker Bee-3 is that it is compact and can be used in a variety of different vehicles. It can even be carried by a jeep and has very good maneuverability. It has a high rate of fire, and all 40 rockets can be launched within 16 seconds, with fierce firepower; The operation is convenient, and it can quickly change from the marching state to the combat state. The disadvantages are the short range, wide spread of bullets, and low density; manual loading and long reloading time; few types of warheads, only high-explosive bombs and yellow phosphorus incendiary bombs; heavy weight, not suitable for human backs and horses. Its weight is almost three times that of the 63 Type 107 rocket on the other side.
