Scientists and technicians in the defence industry of the DPRK succeeded in the development and local production of heat-resisting materials for rocket with their own efforts and technology after having made painstaking researches of years under the direct guidance of supreme leader Kim Jong Un.
Kim Jong Un, first secretary of the Workers' Party of Korea (WPK), first chairman of the DPRK National Defence Commission and supreme commander of the Korean People's Army, gave an order to conduct a test for estimating the heat stability of ballistic rocket warhead tip, designed and manufactured with indigenous efforts and technology, and the corrosion of heat-resistant coating material. And he guided an environmental simulation for reentry of the rocket warhead tip on the spot.
The simulation was conducted in such a way as to verify the thermodynamic structural stability of newly-developed heat-resisting materials through measurement of corrosion and temperature on the tip under high pressure and thermal flow caused by aerodynamic heating when a ballistic rocket reenters the atmosphere. The test results met the requirements of all the technical parameters.
The test proved that the tip's thermodynamic structural stability is ensured under the pressure equivalent to actual environmental condition and heat flow about five times stronger than the condition caused at the time of ballistic rocket reentry and, after all, it provided a sure guarantee for the reliability of the inter-continental ballistic rocket warhead reentry.
Very satisfied over the test results, Kim Jong Un said with high appreciation that the trustworthy scientists and technicians in the defense research field and workers in the munitions industry field true to the WPK's revolutionary line of simultaneously developing the two fronts have made long strides in the rocket industry and nuclear technology this year when the Seventh Congress of the WPK is to be held.
We have proudly acquired the reentry technology, possessed by a few countries styling themselves military powers, by dint of self-reliance and self-development, thus making great progress in the ballistic rocket technology that helps increase the independence of the country's defence capability and munitions industry and remarkably enhance the invincible might of the powerful revolutionary Paektusan army, he added.
The level of our advanced strike means, irrefutable in terms of science and technology, just shows the strength and dignity of our country, he said, stressing the need for the munitions industry to rapidly develop the defence science and technology and raise higher the level of putting the defence industry on a Juche-based, modern and scientific basis and thus develop and produce on the highest level more diverse and Korean-style military strike means and Juche-based rockets for realizing the Party Central Committee's idea on the military strategy and tactics.
Declaring that a nuclear warhead explosion test and a test-fire of several types of ballistic rockets capable of carrying nuclear warheads will be conducted in a short time to further increase the reliability of nuclear attack capability, he instructed the relevant field to make thorough prearrangement for them. He was accompanied by First Vice Department Director Ri Pyong Chol and Vice Department Director Kim Jong Sik of the WPK Central Committee and General Kim Rak Gyom, commander of the KPA Strategic Force.
