He, together with General Kim Rak Gyom, commander of the Strategic Force, and other commanding officers, went round the firing sites to learn about the preparations for ballistic rocket firing. After hearing about its plan, he ordered to kick off the drill.

The drill was conducted by limiting the firing range under the simulated conditions of making preemptive strikes at ports and airfields in the operational theater in south Korea where the U.S. imperialists nuclear war hardware is to be hurled. And it once again examined the operational features of the detonating devices of nuclear warheads mounted on the ballistic rockets at the designated altitude over the target area.

It fully demonstrated the combat capability of the Hwasong artillery units.

Kim Jong Un expressed great satisfaction over the successful drill, highly praising the artillerymen for keeping themselves fully ready to carry out any order issued all of a sudden and for being always exact and elaborate both in maneuverability and striking force.

He assigned the leading officials of the WPK Central Committee, scientists and technicians in the field of research into nuclear weapons and commanding officers of the KPA Strategic Force accompanying him to the tasks of fully ensuring speed and security of the operation of nuclear attack system, rounding off the Juche-based firepower striking methods and developing diverse type ballistic rockets.

He was accompanied by Ri Man Gon, Ri Pyong Chol, Hong Sung Mu, Kim Jong Sik and other leading officials of the WPK Central Committee and scientists and technicians in the field of research into nuclear weapons.
