Capable of hitting alaska and even the west coast of the United States according to some experts. Each missile north korea tested before this was back in may. That had a range of maybe about 300 miles. So this is considerably longer. I think the kind of things theyre doing will allow them to continue to increase the range. North korea believes that possessing Nuclear Weapons capable of hitting the u. S. , is the only way to be taken seriously. The regime is devil offing its weapons more rapidly than most experts thought possible. It claims that tuesdays test improved the accuracy of its icbm and that it can carry a large sized heavy Nuclear Warhead. But one test does not mean that north korea now has reliable Intercontinental Ballistic Missile system. We dont know if theyre able to put a Nuclear Warhead on it as they claim.
