A devoted corps of North Korea watchers analyzes information coming out of North Korea on its missile and nuclear tests. I sometimes chime in, but missiles are not my thing. Much of the conversation takes place on Twitter, so you can see people figuring things out in real time.
First, a summary of this latest test. It seems to have been a successful test of an intermediate-range ballistic missile that North Korea is calling the Hwasong-12. This article summarizes the early information and analysis and links to many of the people who participate in those discussions.
The test appears to have been a success. Kim Jong Un looks overjoyed in all his photos. The missile can reach further than previous North Korean missiles. It is one of the new missiles and missile containers displayed in North Korea’s annual weapons parade last month. The test seems to have been from a platform rather than a mobile launcher, which may indicate that they don’t have a lot of mobile launchers available. It’s a liquid-fueled missile, which means that it must be fueled just before launch, and the propellants are difficult to handle.
