The new type of tactical ballistic missile can carry a "4.5 ton-class super-large warhead," according to a KCNA report, Xinhua news agency reported.

Using a simulated heavy warhead-equipped missile, the test-fire was designed to verify its flight stability and strike accuracy at a maximum range of 500 km and a minimum range of 90 km, the report said.

The DPRK Missile Administration will test the new type of tactical ballistic missile this month to verify its flight characteristics, hitting accuracy and blast power of the super-large warhead at a medium range of 250 km, the report said.
