However the sloppy quality of North Korea provided still photographs and the poor quality Youtube makes ignition only a possibility. The inherent dangers of being near a missile test puts in doubt Kim Jong-un's actual presence so close to the test.
- the newly observed (1,500 ton) Sinpo class. My estimate is that the Sinpo owe's much to the (2,000 ton) Zulu V class design
- or less likely, due to varying tonnages the 1,500 ton Sinpo may be an original or new build of the (3,000 ton) Golf II class design.
Whether the North Korean test missile was more based on a Russian SS-N-5 or SS-N-6 is also contentious.
