North Korea’s Missile Administration tested on Saturday a cluster-bomb warhead for tactical ballistic missiles, assessing the warhead’s combat adaptability and power, according to the Korean Central News Agency (KCNA).

Research institutes under the administration said the Standard Type 2 cluster-bomb warhead is capable of turning into ashes a target area of 12 to 13 hectares with its highest-density power, according to KCNA. South Korea’s Joint Chiefs of Staff said on Sunday that the missile was fired toward the Yellow Sea from an area around the northwestern county of Chongju, and that, under information sharing with the United States, it tracked relevant activities before the launch and maintained a readiness posture.
