Arms Control Wonk
Nice try of North Korea.
But I think these images are so damning. The welding is sub par, the design of the fuel tank is soo wrong. What strikes me,is that two flexible pipes are still attached to the tank. Two others have disrupted the tank. Which leads me to question tank stability.
The internal supports, visible on the image, are soo poorly arranged to the bolts. (which are used to fix the fuel/oxidizer tank to the lower section)
All in all, I would like to compare this to merely upscaled German V2 technology, nothing new (apart from the teflon cabling, that is)
