On the heels of Kim Jong-un suggesting that the country is very close to testing another ICBM, I've discovered three sites that could be used as dedicated mobile-missile-launcher pads.
These sites were constructed in 2016 and have the same general design.
The first and largest is near Kaesong, and lies less than 10 miles (16 km) from the Demilitarized Zone with South Korea.
Located adjacent to the Pyongyang-Kaesong Highway, by the village of Haeson-ri, this site was under construction in March and had been completed by October 2016.
The second site is in Pyongsong, South Pyongan Province, which is 21 miles (34 km) north-northeast of the center of Pyongyang.
Lastly, the third site is similar in its size and the fact it's right off a highway, but its design is different. The primary difference is a lack of a central berm. This site is located near Sukchon, also on South Pyongan.
If these are indeed dedicated pads for launching missiles, it would be inline with North Korea's continued modernization and expansion of their offensive capabilities.
I'd like to make a quick note about the #AccessDPRK Mapping Project. Across North Korea, I have located 9,500 military related places. I have finished the primary mapping process and am now working on incorporating the work of two others into a main and comprehensive single file. After that, the entire body of work will be published.
