The Chinese defense manufacturer, Norinco has developed guided rockets for its SR5 Universal Artillery Rocket Launcher (UARL).
Previously, the SR5 UARL was only capable of firing unguided 122 mm and 220 mm surface-to-surface rockets, with a maximum range of 50 km and 70 km respectively.
The current upgrade, which requires a fire control system modification, will enable the SR5 to utilize Fire Dragon (BRE7) 40 122 mm and King Dragon 60 (GR1) 220 mm guided rockets.
Both guided rockets are equipped with inertial navigation system (INS) and global positioning system (GPS). The 122mm rocket has a minimum range of 20 km and a maximum range of 40 km. The steel ball high-explosive (HE) warhead fitted with a radio proximity fuze, which has a lethal effect of around 60 meters weighs 18kg.
The 220mm rocket has a minimum range of 25 km and a maximum range of 70 km, and can be fitted with various types of warheads including HE and penetration. Unlike the 122mm, the 220mm rocket can be laser guided.
Both rockets have a circular error probability (CEP) of 25 m, with the CEP decreasing to just 3 m in case of laser guidance.
