North Korea's EMP Weapons

Call me crazy, has North Korea completed testing with extremely high altitude ICBMs or whatever. Do you remember the missile shot who only went a few hundred miles , but went to extremely high altitudes. Remember everyone puzzling why it went so high, but never went that far?    

North Korea threat: EMP attack can destroy a nation’s entire infrastructure in a flash

KIM Jong-un needs only one hydrogen bomb to bring America to its knees. And he knows it. This is the nation-wide effect it can have in nanoseconds.

DETONATING a thermonuclear warhead 400km above Washington would instantly fry most of the nation’s power grid — and electronics.

The idea is not about melting a city, set enormous fires and irradiate vast tracks of terrain.

It’s about eliminating a nation’s entire infrastructure in a single flash.

There’s little surprise that North Korean state media has been lauding the power of Electromagnetic Pulse (EMP).

This is where the gamma radiation of a high-altitude nuclear blast interacts with the ionosphere — a blanket of electrons and electrically charged particles surrounding the Earth — to send a series electromagnetic pulses spearing into the ground below.

Once this burst of radiation strikes the ground it can induce strong currents — particularly in electrical cables and phone lines. This can overload and destroy electrical networks, as well as cause delicate circuit boards to fuse.

An entire economy can be brought to a standstill in nanoseconds.

In the words of former director of the CIA James Woolsey, it would bring the United States “to a cold, dark halt”.

ELECTRIC WAR

It’s an effect similar to that of Earth being struck by a serious solar storm, or — at a much smaller scale — when lightning causes a surge in a power grid.

North Korea’s state news agency commented on just such a tactic at the weekend. It follows a series of similar observations about the power of EMP in July.

The latest statement boasts North Korea’s new bomb “is a multifunctional thermonuclear nuke with great destructive power which can be detonated even at high altitudes for super-powerful EMP attack.”

But it’s not an attack without human cost.

It would bring “widespread and long lasting disruption and damage to the critical infrastructures that underpin the fabric of US society,” a 2008 US Congress report warns.

The last time anything on this scale happened was in 1859 — when the world was just beginning to discover the use of electrical technologies. The EMP from an enormous solar storm overloaded the simple telegraph wires then in use to transmit morse code, setting the paper telegrams at their terminals on fire.

Things would be infinitely worse today.

“Two thirds of the US population would likely perish from starvation, disease, and societal breakdown,” Woolsey warned US Congress in 2014. “Other experts estimate the likely loss to be closer to 90 per cent.”

INFRASTRUCTURE ELIMINATED

Hospitals would be without power. Essential services — electricity, gas, water, sewage, communications — would all be offline. Emergency services would be unable to respond. Food production and distribution networks would collapse.

Computers. Smart phones. Car ignitions. Pacemakers. Any form of delicate electronics within the pulse’s effective range would cease to function.

But the greatest damage would be to the power grid itself. Power stations and network transformers would be burnt out.

And the effect of a high-altitude EMP burst would not be localised.

EASY OPTION

Such a high-altitude thermonuclear attack does not require the technical skills necessary to enable a warhead to survive re-entry to the Earth’s atmosphere, cope with the heat of enormous speeds — and still hit its specific target.

Perhaps this is why the devastating power of EMP attack has again appeared in North Korean propaganda broadcasts.

“I can exploit it in high-altitude areas for strategic purposes and (inflict) EMP attacks on vast areas,” Kim Jong-un declared back in July.

In 2015, North Korean propaganda boasted it could destroy all electronic devices in South Korea and Japan by detonating a 100 kiloton bomb 100km above Seoul. “If we lower the altitude to 60-70km, we can make the EMP effect only the southern part of the Korean Peninsula,” it declared.

“(EMP) can neutralize all advanced electronic guided weapons and destroy aircraft carrier fleet at once”.

The warhead it tested yesterday is estimated to be in the vicinity of 50 to 120 kilotons.

But such an attack would not give Kim Jong-un a victory…
