“As a result of analyzing the material of Unha-3 (North Korea’s rocket), we judged North Korea had secured a range of more than 10,000 km in case the warhead is 500-600 kg,” a South Korean Defense Ministry official told a news briefing.
North Korea’s previous missile tests ended in failure.
North Korea, which denounces the United States as the mother of all warmongers on an almost daily basis, has spent decades and scarce resources to try to develop technology capable of striking targets as far away as the United States and it is also working to build a nuclear arsenal.
But experts believe the North is still years away from mastering the technology needed to miniaturize a nuclear bomb to mount on a missile.
South Korean defense officials also said there was no confirmation whether the North had the re-entry technology needed for a payload to survive the heat and vibration without disintegrating.
