North Korea has developed a new long-range mobile intercontinental ballistic missile that the Pentagon says moves the country’s leader Kim Jong Un closer to the goal of building missiles capable of striking the U.S. mainland with nuclear warheads.
The new missile is called the KN-14 by the Pentagon and is a longer-range variant of the KN-08 road-mobile ICBM first made public in 2012.
Both the KN-08 and the new KN-14 have not been flight tested. But defense officials familiar with reports on the weapons said both systems have been tested in all other aspects of their development.
North Korea is believed to have between 10 and 20 nuclear warheads, but its long-range missile capabilities remain uncertain.
