The Type 63 multiple rocket launcher is a towed, 12-tube, 107-mm rocket launcher produced by the People's Republic of China in the early 1960s. 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.The launcher's 12 tubes are arranged in three rows of four each. The Type 63 originally fired a 19 kilogram rocket with a 1.3 kilogram warhead. Ammunition for the Type 63 was improved in 1975, although the overall weight of the rocket remained the same.
