Analysis:
  It is not to overview that the new missile is based on the small Pukguksong-1 SLBM. It is quasi a single-stage PS-1 (without adding a segment like the "PS GLBM-2").  Details here.
The launch takes place from a 8-axles tracked vehicle with two parallel mounted box-shaped containers without bottom. These are lifted hydraulically at a specific angle before launching. The "PS GLBM-1" is about 7.2m long and 1.1m in diameter. It has nothing to do with the small ATACMS.
