Analysis


The Pukguksong-2 (GLBM and SLBM) is significantly different from der small Pukguksong-1. The diameter of the missile is about 40 cm increased. The whole missile, including the cold-start system, also seems to be of new quality. It is quite a puzzle what the origin is from this so suddenly emerging complex system, which functions after only two failures. It could be that all this motors for the PS-1 and PS-2 are based on a almost unknown Soviet RT-15M SLBM as template. In any case, the truck is an changed old Soviet caterpillar, used for the RT-15 missiles.
