Exclusive: How North Korea Tipped Its Hand

The U.S. recovered the front section of the rocket used in North Korea’s satellite launch in December, which gave away the status of the regime's nuclear arms program.



When North Korean engineers launched a satellite into space on December 12, it seemed like business as usual, with the familiar cycle of condemnations from the west and statements of defiance from the Hermit Kingdom. But that launch also led many U.S. intelligence analysts to assess that Pyongyang possessed the ability to miniaturize the components necessary to yield a nuclear explosion for a crude warhead that would sit atop a ballistic missile.

By successfully firing a rocket that put a satellite in space, North Korea let the far-flung buyers of its missiles know that it is still open for business.

After the North Korean launch, U.S. Navy ships managed to recover the front section of the rocket used in it, according to three U.S. officials who work closely on North Korean proliferation. That part of the rocket in turn provided useful clues about North Korean warhead design, should the next payload be a warhead rather than a satellite.

The same basic engineering and science needed to launch a satellite into space is also used in the multi-stage rockets known as inter-continental ballistic missiles. The front of the satellite rocket, according to three U.S. officials who work closely on North Korean proliferation, gave tangible proof that North Korea was building the missile’s cone at dimensions for a nuclear warhead, durable enough to be placed on a long-range missile that could re-enter the earth’s atmosphere from space.

“Having access to the missile front was a critical insight we had not had before,” one U.S. non-proliferation official told The Daily Beast. “I have seen a lot of drawings, but we had not seen the piece of that missile at that time.” This official continued: “we looked at the wreckage from the launch and we put it together with other kinds of intelligence and came to this judgment that they had figured out the warhead piece.
