As I suspected, some of North Korea’s recent “MLRS” tests are more likely tests of the solid-fueled SS-21 Toksa SRBM. The missile in question is an extended-range SS-21, that may eventually be dubbed the KN-10. The Chosun Ilbo reported that North Korea was developing such a missile in October 2013.
Based on the images from the 14 August launch, I’ve geolocated both the launch and impact sites. I’ve embedded the findings. Tell me what you think.
