Pyongyang, September 13 (KCNA) -- The Academy of Defence Science of the DPRK successfully test-fired new type long-range cruise missiles on September 11 and 12.

Pak Jong Chon, member of the Presidium of the Political Bureau and secretary of the Central Committee of the Workers' Party of Korea, watched the test-launches with Kim Jong Sik and Jon Il Ho, vice department directors of the Party Central Committee.

Leading officials and scientists in the field of the national defence science took part in the test-launches.

The development of the long-range cruise missile, a strategic weapon of great significance in meeting the key target of the five-year plan for the development of the defence science and the weapon system set forth at the 8th Congress of the Party, has been pushed forward according to the scientific and reliable weapon system development process for the past two years and, in this course, detailed tests of missile parts, scores of engine ground thrust tests, various flight tests, control and guidance tests, warhead power tests, etc. were conducted with success.

The development of this weapon system that has been powerfully pushed forward as a crucial work under the special concern of the Party Central Committee holds strategic significance of possessing another effective deterrence means for more reliably guaranteeing the security of our state and strongly containing the military maneuvers of the hostile forces against the DPRK.

The test flights were successfully held.

The launched long-range cruise missiles traveled for 7 580 seconds along an oval and pattern-8 flight orbits in the air above the territorial land and waters of the DPRK and hit targets 1 500 km away.

The test launches showed that the technical indices such as the thrust power of the newly developed turbine-blast engine, the missiles' navigation control and the end guided hit accuracy by the combined guided mode met the requirements of designs.

In all, the efficiency and practicality of the weapon system operation was confirmed to be excellent.
