On October 31, the DPRK's General Directorate of Missiles tested a cluster warhead for a tactical ballistic missile. The purpose of the launch was to assess the system's strength and applicability in combat conditions, reports KCNA. The experiments tested the warhead's ability to hit targets in a given area. A day earlier, the North Korean military conducted its first public firing of a 600 mm KN-25 multiple launch rocket system.
