"North Korea's last round of tests, conducted in May 2009, appear to have included a "super-EMP" weapon, capable of emitting enough gamma rays to disable the electric power grid across most of the lower 48 states, says Dr. Peter Vincent Pry, a former CIA nuclear weapons analyst and president of EMPact America, a citizens lobbying group.
Samore, who handles arms control and non-proliferation issues, warned that "additional strong sanctions will be imposed on the North with the support of Russia and China."
North Korea's nuclear tests have been dismissed as failures by some analysts because of their low explosive yield. But Dr. Pry believes they bore the "signature" of the Russian-designed "super-EMP" weapon, capable of emitting more gamma radiation than a 25-megaton nuclear weapon.
Pry believes the U.S. intelligence community was expecting North Korea to test a first generation implosion device with an explosive yield of 10 to 20 kilotons, similar to the bomb the U.S. exploded over Nagasaki in 1945. He said, "So when they saw one that put off just three kilotons, they said it failed. That is so implausible."
The technology for producing a first generation implosion weapon has been around since 1945, and is thoroughly described in open source literature.
South Korean defense minister, Kim Kwan-jin, told his country's parliament on Monday that North Korea had succeeded in miniaturizing its nuclear weapons design, allowing them to place a nuclear warhead on a ballistic missile."
Both North Korean nuclear tests look suspiciously like a Super-EMP weapon. A Super-EMP warhead would have a low yield, like the North Korean device, because it is not designed to create a big explosion, but to convert its energy into gamma rays, that generate the EMP effect. Reportedly South Korean military intelligence concluded, independent of the EMP Commission, that Russian scientists are in North Korea helping develop a Super-EMP warhead. In 2012, a military commentator for the People’s Republic of China stated that North Korea has Super-EMP nuclear warheads.
A Super-EMP warhead would not weigh much, and could probably be delivered by North Korea’s ICBM. The missile does not have to be accurate, as the EMP field is so large that detonating anywhere over the United States would have catastrophic consequences. The warhead does not even need a re-entry vehicle, as an EMP attack entails detonating the warhead at high-altitude, above the atmosphere.
So, as of Dec. 12, North Korea’s successful orbit of a satellite demonstrates its ability to make an EMP attack against the United States — right now.
The Congressional EMP Commission estimates that, given the nation’s current unpreparedness, within one year of an EMP attack, two-thirds of the U.S. population — 200 million Americans — would probably perish from starvation, disease and societal collapse.
The latest nuclear test, which was conducted underground, had a low kiloton yield but sources say that scientists can scale it up potentially to achieve a megaton device.
In addition, U.S. intelligence is aware that North Korea and Iran years ago had obtained blueprints on how to miniaturize a nuclear weapon from the Pakistani A.Q. Khan, father of the Pakistani nuclear bomb.
It is possible that the nuclear test over the weekend was based on those blueprints which Khan had provided to both countries almost a decade ago.
Informed sources say that North Korea and Iran are collaborating not only on missile delivery systems but also exchanging technical data and North Korean scientists are to assist Iran with its possible development of a nuclear weapon.
