High-resolution photographs of the aiframe for North Koreas Pukguksong submarine-launched ballistic missile have a surprise. The airframe appears be wound-filament, not the simple metal airframes weve seen on North Koreas space launchers. That opens up a lot of possibilities for North Korea and ticks off an important requirement North Korea to build a solid-fueled ICBM in the future.

They have to be taken out before it is too late.
