"Juche" is a key word used in the country's communications, though it is concept more than reality.According to the source, North Korea recently completed upgrading the previous model of its 240-millimeter rocket launchers, and named them 'Juche 100 Guns,' after the North's primary ideology of self-reliance.
Some military experts do not believe the reports of doubled range on any new rockets in North Korea:
http://koreatimes.co.kr/www/news/nation ... 05833.htmlsenior rocket expert at the Defense Acquisition and Program Administration (DAPA) said the media reports were baseless unless the North has successfully developed a propulsion system that is a quantum leap ahead of advanced countries, including the United States and Russia.
“I’m highly skeptical that the North has technology that even the United States has yet to develop and the world has yet to witness,” he said.
“The range of the South’s 227-millimeter multiple launch rocket system is limited to 45 to 46 kilometers, despite the fact that it has employed the advanced technology of the United States.”
