A familiar approach. Notably, on Friday, North Korea
chose to launch the IRBM out of Sunan--the same site where Kim Jong-un observed a Hwasong-12 launch on August 29
. The August 29
launch was North Korea
's first-ever overflight of Japan with a ballistic missile system. (It had previously flown four satellite launch vehicles over Japanese territory, but those were not designed to delivery any sort of explosive payload.) The choice of Sunan again suggests that North Korea
see this airfield as a major missile basing site, adding to a constellation of such sites across the country.
