North Korea was able to construct a makeshift assembly facility for intercontinental ballistic missiles (ICBMs) near Pyongyang in less than a month, Voice of America reported earlier this week, citing commercial satellite imagery.
The US government-funded news agency says the building is situated in Pyongsong, South Pyongan Province.
Chosun Ilbo, in picking up the story, says that satellite images shot by commercial provider DigitalGlobe on November 21 showed an oblong building about 35 m tall and by 15-18 m across in the center of the plant.
North Korea launched a Hwasong-15 ICBM from Pyongsong on November 29, about a week after the images were shot.
But an image of the same area shot on October 24 of last year shows only a jumble of what appears to be building materials. This indicates to analysts that the facility took less than a month to complete.
