Kim Jong Un Guides Ballistic Rocket's Reentry Environmental Simulation

Pyongyang, March 15 (KCNA) -- 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, supreme leader of the Democratic People's Republic of Korea, 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. 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. 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. -0-
