This would have provided Pyongyang its first truly intercontinental ballistic missile, capable of reaching new York.


Eventually, the Hwasong-15 to be tested, peaking at an approximated altitude the 4,500km - 10 times greater than the International an are Station.


If fired ~ above a more conventional "flatter" trajectory, the missile might have a maximum range of some 13,000km, putting every one of the continental us in range.


It has actually not yet been named or tested. Like the Hwasong-15, it is a two-stage liquid sustained missile, but with a higher length and also diameter. It can possibly enable for multiple warheads.
