Kim Jong Un learned about the tactical and technological specifications of the newly developed ballistic missile and watched its test-fire.

As soon as he issued an order to begin the test-fire, a combat alarm was sounded inside the strategic submarine and it submerged up to a depth for firing the ballistic missile.

After a while, the ballistic missile soared into the sky from underwater.

The test-fire proved and confirmed that the ballistic missile fired from the submarine fully met the requirements of the latest military science and technology.

He highly praised the officials, scientists and technicians in the field of defence science and a munitions factory for having successfully perfected the technology of firing ballistic missile from the strategic submarine underwater in line with the strategic intention of the Central Committee of the WPK.

He said that the successful test-fire of ballistic missile from Korean-style attack submarine is an eye-opening success as signal as satellite launch.

A wonderful gift was presented to the 70th anniversary of the founding of the WPK thanks to the painstaking efforts of the officials, scientists, technicians and workers in the field of defence science and a munitions factory, he noted, extending his thanks to them on behalf of the C.C., the WPK.

He stressed that the acquisition of the technology of firing ballistic missile from a strategic submarine underwater made it possible for the KPA to possess a world-level strategic weapon capable of striking and wiping out in any waters the hostile forces infringing upon the sovereignty and dignity of Songun Korea and conduct any underwater operation.
