The new North-Korean missile was shown in Pyongyang during celebrations for the centennial of the birth of late North Korean founder Kim Il Sung on April 15,  2012. The TEL LRBM, made of three stages, was unveil at the military parade.
It is estimated that the missile is about 18 meters long. First and second stage have a diameter of about 2 m. Then the third stage has 1.5 m diameter.
The 8-axle TEL is a  Chinese special-made WS51200. The NATO code name of the missile is KN-08.

These images indicates, it is a liquid fuel missile

Other analysts estimate that - at least for the first stage of the rocket - a technology of the Soviet R-27 SLBM is used (the main engine is placed inside of the fuel tank).

An application of the R-27 technology would be not a possibility because about 250 kN thrust of a R-27 engine is not enough for this monster. Two engines to combine is technically in this case impossible.

An acceptable thrust of about 500 kN has the engine of  a Russian R-29 SLBM (RSM-40 Vysota)  with similar technology.
 

Attention analysts, the missile is certainly not yet complete, but not fake!
I think that the KN-08 is not a fake, and North Korea working on developing an LRBM. The technology is based on a proven (!!) template. North Korea does not have the know-how and financial resources to develop such a complicated missile with new liquid rocket engines.

With high probability is the technology not Chinese. China has never developed a "submerged engine" technology, or used. Furthermore, it is against China's doctrine such significant potential of rocket technology to export. China only supplies to Pakistan missile technology (Shaheen).
The delivery of the large TELs to North Korea must based on a "misjudgment".

The noted differences between the rockets - missing retro-rockets, different length of cable ducts and different positions of covers - are optical illusions or evidence for the incompleteness of the rocket. A slightly shifted retaining band on one rocket (No. 218) is not relevant for the analysis.

But a puzzle for my proposal is the interrupted cable duct between first and second stage. Why is this interruption on No.18 so short? The interruption of the cable duct is probably temporary, to place the retaining band. It is impossible to find an interstage section.
Furthermore, a separation plane between the first and second stage is also never visible.
 

Want they to confuse us, or is it a mock-up. Is it really a mock-up, then has but this missile a serious technological background.

Analysts argue that the use of UDMH/N2O4 as fuel for the road-mobile missile KN-08 is no option because the risk is not acceptable. But the refueling would be possible before the launch in the erected position !

A number of inconsistencies in the upper part of the rocket, which is obviously a mock-up
