North Korean technicians check the Unha-3 rocket at the Sohae Satellite Launch Station in Tongchang-Ri on April 8, 2012.

WASHINGTON — North Korea is pursuing the "rapid rebuilding" of the long-range rocket site at Sohae Launch Facility, according to new commercial imagery and an analysis from the researchers at Beyond Parallel.

Sohae Satellite Launching Station, North Korea's only operational space launch facility, has been used in the past for satellite launches. These launches use similar technology to what is used for intercontinental ballistic missiles.
