Pyongyang, January 7 (KCNA) -- The Missile Administration of the Democratic People's Republic of Korea successfully conducted a test-fire of new-type intermediate-range hypersonic ballistic missile on January 6. General Jang Chang Ha, general director of the Missile Administration of the DPRK, and leading officials of the defence science institute guided the test-fire on the spot. Kim Jong Un, general secretary of the Workers' Party of Korea and president of the State Affairs of the Democratic People's Republic of Korea, oversaw the test-fire of new-type intermediate-range hypersonic ballistic missile through a monitoring system. The test of the new strategic weapon system is part of the plans for the development of the national defence capabilities to raise the durability and effectiveness of strategic deterrent against potential rivals in conformity with the changing regional security environment. The new compound of carbon fiber was used in the manufacture of the engine body of the new-type hypersonic missile and a new comprehensive and effective method based on the already-accumulated technologies introduced in the flight and guidance control system. Expressing great satisfaction over the result of the test-fire, the respected Comrade Kim Jong Un referred to the new weapon system. He said: The current test-fire proved without doubt that we are actively developing such powerful new-type weapon systems as intermediate-range hypersonic ballistic missile to cope with different security threats the hostile forces posed to our state at present. A few countries in the world might possess such weapon system. Just like the intentional purpose of all military powers, the development of new-type hypersonic missile is mainly aimed to steadily put the country's nuclear war deterrent on an advanced basis by making the means of changing the war situation, the weapon system to which no one can respond, the linchpin of strategic deterrence. This is clearly a plan and effort for self-defence, not an offensive plan and action. As shown by the result of today's test-fire, the effectiveness of the missile system fully equipped with the expected militant performance was confirmed. The performance of our latest intermediate-range hypersonic missile system can not be ignored worldwide, and the system can deal a serious military strike to a rival while effectively breaking any dense defensive barrier. Through the current test of the strategic weapon, we fully demonstrated the potentiality and development speed of our inexhaustible self-defensive technical force capable of fully coping with prospective threats and clearly showed the rivals what we are doing and that we are fully ready to use even any means to defend our legitimate interests. The hypersonic missile system will reliably contain any rivals in the Pacific region that can affect the security of our state. We have acquired a technical force which is by no means easy. This is a clear achievement and a special event in strengthening the self-defensive capabilities of which we should be proud. I express thanks to all the researchers and technicians and the workers of munitions industry enterprise, who contributed to the successful development of the new-type strategic weapon system. The hypersonic glide vehicle of the missile fired northeastward at a launching ground in a suburb of Pyongyang reached its first peak at the height of 99.8 kilometers and the second peak at the height of 42.5 kilometers while making 1 500-km-long flight as scheduled at the speed amounting to twelve times of the speed of sound and accurately landed on the waters of simulated target in the open sea. The test-fire had no negative effect on the security of the neighboring countries. The development of the defence capabilities of the DPRK aiming to be a military power will be further accelerated.
