JRTC VISMOD: Type 63 Chinese 107mm Multiple Rocket Launcher (MRL)

The Type 63 multiple rocket launcher is a towed, 12-tube, 107mm rocket launcher produced by the People's Republic of China in the early 1960s and later exported and manufactured globally. Although no longer serving with active infantry units, the Type 63 is still in People's Liberation Army service with specialized formations such as mountain infantry units and special forces detachments. The Type 63 was widely used in the PLA until the late 1980s. It was adopted as the successor of the Type 50-5, 102mm. China has also developed a Type 63 multiple rocket launcher, 130mm. The RPU-14 is a Soviet 140mm MRL of similar design to the Type 63. The launcher's 12 tubes are arranged in three removable rows of four each, mounted on a single-axle carriage with rubber tires. The Type 63 originally fired an 18.8 kilogram rocket (Type 63-2) with a 1.3 kilogram warhead. Ammunition for the Type 63 was later improved (Type 75 and Type 81 series), although the overall weight of the rocket remained the same. A fixed amount of propellant is contained in the rocket motor. The steel-cased rocket is stabilized with spin imparted by six angled nozzles in its base. Type 63 rockets may be launched without the launcher; improvised firing can employ tubing, rails or even dirt berms. The Type 63 was distributed on the basis of six per infantry regiment, or 18 per infantry division. For airborne and mountain units the lighter Type 63-I was developed. Both the Type 63 and its copies can be mounted on different kinds of armored and unarmored vehicles, for example the MT-LB, the Safir, the Mamba, the RG-32 Scout, the GAZ-66 and the M113.
