It looks like the intel guys have found their missing missile:

North Korea has finished preparatory work at a missile launch pad in Tongchangri, North Pyongan Province, where a long-range missile has been transported, a South Korean government source said Monday. “But the launch is not imminent because no radar has been set up and no missile has been installed at the launch pad,” the source added.

But the launch structure connecting electric power and fuel to the missile and allowing personnel to check the missile has been erected. That means North Korea is speeding up preparations to launch a long-range missile there.

Expert analysis of satellite photos shows the launch structure is about 50 m high, much higher than the 30 m it had previously been believed to be. A launch pad of this height is capable of firing an intercontinental ballistic missile measuring 40 m or longer.

The old launch pad at the Musudanri launch site in North Hamgyong Province is a mere 32m high. The whole Tongchangri launch site actually seems to be three times as large.  [Chosun Ilbo]
