What’s Going On With North Korea’s Nuclear Programme
North Korea’s growing missile prowess and nuclear capability are starting to pose a serious threat not just to the South, but most of the world

The weapon in question is an intercontinental ballistic missile (ICBM), a super-fast, long-range missile designed to carry nuclear bombs and detonate them over a specific target. ICBMs, which are launched from land, are closely related to intercontinental-range submarine-launched ballistic missiles (SLBM), which are also nuclear capable.
These nuclear-tipped missiles are incredibly difficult to make, and only seven countries are known to have managed the feat: the United States, Russia, China, India, France, the United Kingdom, and Israel. Despite sanctions from international bodies, isolated North Korea also hopes to make a missile powerful enough to launch a nuclear attack.

Last year, North Korea successfully tested two ICBMs, Hwasong-14 and Hwasong-15, the latter of which is believed to be capable of reaching the US mainland. However, the country has yet to prove it can produce a nuclear warhead compact enough for the missiles to deliver. One significant hurdle is making a sufficiently lightweight shroud, the cover that protects the warhead from melting in the heat of re-entry, as the missile would hit the ground at over 25,000 km/h. In response, other countries – particularly the US – are looking into making reliable missile defence systems that can shoot down an ICBM, but during tests, few have managed to hit targets as fast as an ICBM.
