The test was overseen by Pak Jong Chon, vice-chairman of the Central Military Commission of the Workers' Party of Korea (WPK) and secretary of the WPK Central Committee, and Kim Jong Sik, first vice department director of the WPK Central Committee.

The test was carried out by use of the first-stage engine of an intermediate-range solid-fuel ballistic missile within a 170~200 km radius, which is favourable for ensuring maximum safety and measuring the flight characteristics of individual mobile warheads.

The separated mobile warheads were guided correctly to the three coordinate targets.

The effectiveness of a decoy separated from the missile was also verified by anti-air radar.

The test is aimed at securing the MIRV capability.

The test is part of the normal activities of the administration and its affiliated defence science institutes for the rapid technical development of weapon systems.

According to the administration, it is of great significance in bolstering up the DPRK's missile forces and developing the missile technologies that such technological test has entered a full-scale stage.

The senior officials, who watched the test, said that to enhance the MIRV capability is a very important defence technological task and a top priority of the WPK Central Committee, stressing the need to take proper scientific and technological steps to further improve the effectiveness of decoys.
