The test was aimed to examine the structural safety of the rocket engine newly designed and manufactured by the Korean style and its thrust and estimate the working specifications of heat separation system and other system.

Before the test, he touched the engine smoothly and said with confidence that the test would prove successful as it was manufactured by defence scientists and technicians of the DPRK, a product of self-reliance and self-development.

He gave an instruction to start the test.

The engine spewed out huge flames with deafening boom.

The results of the test proved that the values of estimation conformed to those of measurement to an amazing extent and they are in full line with all scientific and technological indexes.

He expressed great pleasure and satisfaction, clapping his hands and congratulating them on their success.

He noted with great pleasure that the successful test provided a firm guarantee for attaining the high goals of national defence science and technology without fail this year when the Seventh Congress of the WPK would be held and helped boost the power of ballistic rockets capable of mercilessly striking hostile forces.

The successful test of the jet and cascade separation of the above-said rocket engine which is of historical and strategic importance by dint of self-reliance and self-development makes it possible to remarkably bolster the military capability of the invincible revolutionary Paektusan army, he noted, stressing that the feats the national defence scientists and technicians of the DPRK performed by working hard to increase the national defence capability would always go down in the history of the country. He had a photo session with them.

He expressed expectation and belief that the scientists and technicians in the field of national defence science would achieve successes one after another to instill conviction and optimism into the service personnel and people of the DPRK and, at the same time, strike great horror and terror into the hearts of the enemies, bearing in mind the heavy yet honorable duties they have assumed before the times, the revolution, the country and its people.
