North Korea’s Missiles and the US-NK Summit

, co-director and senior scientist

In April 2018, shortly before last June’s summit with President Trump, North Korea announced it was discontinuing its flight testing of ballistic missiles. For over a year now, it has not conducted any missile tests.

This represents a big change. In the five years 2013 to 2017, North Korea launched more than 80 flight tests of 10 different missiles, or an average of 16 flight tests per year. In 2017 alone, it launched 20 tests of seven types of missiles, including the successful launch of two different long-range missiles. Read more >

Reentry of North Korea’s Hwasong-15 Missile

, co-director and senior scientist

Photos of the Hwasong-15 missile North Korea launched on its November 29 test suggest it is considerably more capable than the long-range missiles it tested in July. This missile’s length and diameter appear to be larger by about 10 percent than July’s Hwasong-14. It has a significantly larger second stage and a new engine in the first stage that appears to be much more powerful.

While we are still working through the details, this strongly implies that North Korea could use this missile to carry a nuclear warhead to cities throughout the United States. A final possible barrier people are discussing is whether Pyongyang has been able to develop a reentry vehicle that can successfully carry a warhead through the atmosphere to its target, while protecting the warhead from the very high stresses and heat of reentry.

Did Pilots See North Korea’s Missile Fail during Reentry?

, co-director and senior scientist

News reports say that a Cathay Airlines flight crew on November 29 reported seeing North Korea’s missile “blow up and fall apart” during its recent flight test. Since reports also refer to this as happening during “reentry,” they have suggested problems with North Korea’s reentry technology.

But the details suggest the crew instead saw the missile early in flight, and probably did not see an explosion. Read more >
