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 diligent 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 orders of conducting a test for estimating the heat stability of rocket warhead tip, designed and manufactured with domestic efforts and technology, and the erosion of heat-resistant coating material. And he guided an environmental simulation for reentry by the warhead tip on the spot.

The simulation was conducted in such way of verifying the thermodynamic structural stability of newly-developed heat-resisting materials through measurement of the erosion degree and internal temperature of the tip under the high pressure and thermal flow caused by aerodynamic heating when a ballistic rocket reenters the atmosphere. The test results met the needs for 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, technicians and workers in the munitions industry 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 as military powers, by dint of self-reliance and self-development, thus making a great progress in the ballistic rocket technology that helps strengthen 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 military 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 more on the highest level diverse and Korean-style military strike means and shells 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 kinds of ballistic rockets able to carry nuclear warheads will be conducted in a short time to further enhance the reliance of nuclear attack capability, he instructed the relevant section to make prearrangement for them to the last detail.

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.
