An EMP Bomb is a complex multi-pulse nuclear weapon that can be
best described in three components (E1, E2 & E3) as advanced by the
International Electrotechnical Commission (IEC).
This is the first component of a nuclear Eletromagentic Pulse
(EMP) and is usually a brief but intense electromagnetic field capable of
inducing very high voltages in electrical conductors. As a result, the pulse
causes breakdown of such conductors typically computers and communication
devices. Since it happens fast, ordinary surge protectors can’t offer enough
fortification as much as they are effective against such incidences.
The E1 effect is also known as the Compton Effect produced when
gamma radiation from the detonated nuclear EMP bomb ionizes atoms in the upper
atmosphere. The resulting current is the Compton Current. The electrons will
then travel downwards at relative speeds (90% more than the speed of light).
The Earth’s magnetic field will then deflect the flow (at a right-angle to the
field) producing very large but brief electromagnetic pulse over the affected
This is a component generated by scattered gamma rays and
inelastic gammas produced by neutrons. It lasts for roughly 1 micro-second to 1
second after the explosion of the EMP Bomb or any other nuclear device that
emits Electromagnetic Pulse. Though it has a lesser effect, E2 bears some
similarities to lightning and is generally considered to be the easiest to
protect against. The problem with E2 however is that it comes immediately after
E1 has already damaged protective devices that would normally withstand E2
pulse. By destroying control features, it still poses a great risk to critical
This EMP differs greatly from both E1 and E2 because it is a very
slow pulse. It is normally caused by the temporary distortion of the Earth’s
magnetic field after a nuclear detonation. It is slight similar to a
geomagnetic storm caused by a solar flare. E3 normally induces current in
extended electrical conductors like power line transformers thereby damaging
The Effects of a Lack of Protection
Like most nuclear devices, an EMP Bomb produces magnetic wave of
electric current ( 100,000 volt power surge brought in through the power
distribution lines) that creates fire, damages transformers, breaks down
insulation creating arcing and short circuits. The EMP will disable any
electronic equipment whether they are connected to the grid or unplugged. Devices
that have integrated circuits are usually very sensitive to static electricity
and can be destroyed by as little as 100 volts.
When an EMP Bomb strikes, the resultant nuclear explosion at
altitude will emit a pulse of broadband energy which will radiate outwards from
the source. Therefore, electronic devices further away from the Electromagnetic
Pulse source may likely be less affected. Still, even if the devices are
unplugged they will be vulnerable to the invisible pulse that envelopes
everything in its path. Only those devices protected in a Faraday cage can
survive such an attack. A Faraday cage is a box made of conductive metal grids
whereby the EMP current is induced in those metals rather than through the
circuits of the electronic devices being protected inside.
Generally, an EMP attack whether from EMP Bomb or any nuclear
device will damage almost all electronic devices in their path. The extent of
damage however depends on the proximity to the EMP source. Unless electronics
are protected through a natural Faraday cage, they will melt under the surging
currents through the power lines. A major EMP will therefore be the end of
civilization as we know it.
The possibility of a disastrous attack to the United States electrical network by nuclear states like North Korea or Iran has caused the North American Aerospace Defense Command (NORAD) to go back to its past location within Cheyenne Mountain near Colorado Springs, Colorado, 2 former Reagan-era federal representatives wrote in The Wall Street Journal.
“Why the return?” wrote Henry F. Cooper and Peter Vincent Pry. “Because the enormous bunker in the hollowed-out mountain, built to survive a Cold War-era nuclear conflict, can also resist an electromagnetic-pulse attack, or EMP.”
Meantime the Government is relocating to shield its worldwide air defense command from being knocked out by an electromagnetic pulse (EMP) attack, the Obama administration has failed to pursue urgent endorsements to shield the nation’s civilian electronic infrastructure from a similar disaster, they write.
“An EMP strike, most likely from the detonation of a nuclear weapon in space, would destroy unprotected military and civilian electronics nationwide, blacking out the electric grid and other critical infrastructure for months or years,” Cooper and Pry write.
“The staggering human cost of such a catastrophic attack is not difficult to imagine.”
The likeliest source of such an attack would be N. Korea or Iran, says Cooper, past leader of the Strategic Defense Initiative, introduced by the late President Ronald Reagan, and Pry, executive director of the EMP Task Force on Nationwide and Homeland Security and a veteran of the C.I.A.
Iran is nuclear ready state with ballistic missiles capable of attacking the United States of America now, Cooper, Peter Vincent Pry and two other Reagan administration leaders wrote.
In the Wall Street Journal, Cooper and Pry say again that “Iran should be considered as currently possessing nuclear missiles capable of causing an EMP attack over the United States,” noting, “Iran and N. Korea have actually skillfully orbited satellites on South-Polar trajectories that look as if to practice escaping U.S. missile self-defense, and at ideal heights to make a secret EMP attack.”
There is by no means similar initiative in progress in Washington DC to defend civilian electronic infrastructure, despite the fact that a long term nationwide collapse would create chaos and death on a massive scale, according to findings of a national EMP Commission created by Congress.
“Yet President Obama has not acted upon the EMP Commission’s draft executive order to secure national infrastructure that is necessary to provide for the common defense,” Cooper and Pry wrote. “Hardening the national electric grid would cost a few billion dollars, a trivial amount compared with the loss of electricity and lives following an EMP attack.”
The authors in addition fault Congress for falling short to follow up on the suggestions of its own commission and for slipping on numerous bills to finance electronic infrastructure security upgrades.
“In recent years, the GRID Act, the Shield Act, and the Critical Infrastructure Protection Act have gained bipartisan and even unanimous support in the House, yet they did not make it past the Senate,” they write.
One final result, Cooper and Pry write, is that individual states have been entrusted to pursue answers by themselves.
What is it?
A Faraday cage is essentially a metal box that works by three mechanisms: (1) the conductive layer reflects inbound fields, (2) the conductor soaks up inbound energy, and (3) the cage acts to produce opposing fields. All these work to safeguard the contents from excessive field levels. A Faraday cage is specifically useful for safeguarding against an electromagnetic pulse that might be the result of a high-altitude nuclear detonation in the atmosphere (EMP attacks).
In spite of reports to the contrary, a Faraday cage is not required to protect against solar coronal mass ejections since the frequency content of such disruptions is at considerably lower frequencies– they do not couple energy effectively into small-scale electronics, other than through conducted paths (wires/antennae). A better precaution against solar radiation is to disconnect electronics from outlets.
Does it matter exactly what type of conductor is made use of?
Not really. The conductivity of almost any metal is enough to make the carriers easily straighten to cancel external fields as shown in the picture above. As an example, silver is the very best conductor available, so less would be required to use vs utilizing a product such as aluminum that isn’t as conductive. Obviously, since silver is so expensive no one would actually make one from silver.
Can a Faraday cage contain openings?
Yes, as long as the holes are small with regard to the wavelength of the event electromagnetic wave. Just like your microwave has a mesh screen in the window to protect you from the radiation going on when cooking food. As long as the holes are substantially smaller than that dimension (2mm or smaller), they will not allow much of the occurrence wave inside. This is why fine conductive mesh can be made use of when constructing a Faraday cage. In practice, the cage’s lid or door generally triggers the most leakage. Taping the seam with conductive tape assists to minimize this leakage.
Can you use existing conductive enclosures?
Yes, there are many conductive enclosures that can be made use of, including ammo cans, metal trash cans, EMP bags, as well as old microwave ovens. The finest alternative is to either make a faraday cage correctly or use faraday bags pre-made to high military requirement. Each has its own level of effectiveness. Since Tech Protect faraday bags are to high military standard it is a great and easy solution for anyone.
Does it need to be grounded?
There is a good deal of confusion regarding grounding of a Faraday cage. Grounding of the cage (i.e., connecting it to some Earth-referenced source of charge) has little effect on the field amounts seen within the box. Grounding mainly assists to keep the cage from ending up being charged and possibly re-radiating. The bottom line is that an ungrounded enclosure secures the contents from unsafe electromagnetic fields in addition to a grounded one.
EMP bags are easily accessible to secure electronic parts against electrostatic discharge. They can be acquired in various sizes, consisting of some large enough to hold radio devices and other to store solar generators. While they do offer shielding from EMP, not all items are created equal. Testing confirmed that products accredited to MIL-B-81705-Rev-C are of the greatest quality and can be depended on to be safe versus EMPs. Even still it is always recommended to nest bags (placing one inside of the other).
U.S. News and World Report posted an article that asks the question of why our country is not prepared for an EMP attack. Although EMP is a well-documented security issue, and one of the very few things that experts believe can dramatically alter our modern way of life, the U.S. government has sadly followed the lead of too many others and done little. This inaction could well prove fatal.
An article on Fox News reveals there may be new technology to detect the source of an EMP attack, including the attack’s strength, frequency and duration. Researchers in Europe are developing this technology. Such a device would be an engineering feat, since it would need to withstand the blast and also measure high field strengths from short pulses.
A recent article in the Washington Times outlines the risks of missile threats and the rewards of missile defense.
The EMP threat to the American homeland challenges description. A large EMP warhead exploded high over the center of the United States would completely disable the entire national electrical grid. Aircraft would fall out of the sky, vehicle engines would die, communications, the Internet and computers would fry, and civilization on the continent would be set back a century.
Next year, the North American Aerospace Defense Command will test an innovative weapon called the Joint Land Attack Cruise Missile Defense Elevated Netted Sensor System, or JLENS, at the Army’s Aberdeen Proving Ground, 63 air miles from the nation’s capital. Integrated with existing defenses, the system would protect the capital from short-range missile threats.
Today, a gathering storm threatens freedom and the survival of civilization: cyberwarfare.
An article by Newt Gingrich on CNN.com explains the threat of cyberwarfare and its catastrophic effects.
See below for an excerpt of the article or click here for the full article.
Terrorists and rogue states are making cyberattacks on a daily basis, using computer bugs to probe defenses of U.S. critical infrastructures. The most important critical infrastructure is the electric power grid. Electricity runs and makes possible the operation of all the other critical infrastructures — communications, transportation, banking and finance, food and water — that sustain modern civilization and the lives of millions.
The biggest cyberthreat is from electromagnetic pulse, which in the military doctrines of potential adversaries would be part of an all-out cyberwar. A nuclear missile, perhaps launched from a freighter, detonated at high altitude over the U.S. could black out the national grid for months or years, killing an estimated 90% of Americans by starvation, disease and societal collapse. (And there is also a natural threat: The sun could inflict a worldwide natural EMP catastrophe with a solar flare that generates a rare geomagnetic superstorm, like the 1859 Carrington Event. Such a storm could collapse electric grids everywhere on Earth, endangering billions.)
The National Geographic channel is airing a new summer television series that focuses a family completing the ultimate survival bunker, a castle deep in the Carolina hills, in preparation for an EMP that would plunge the modern world into a new dark ages.
The first episode airs on August 13, 2013 on the National Geographic Channel.

A large enough pulse (EMP) could destroy the electric grid, notably the rare and very expensive transformers that form the grid’s backbone. Without them and the power they deliver, a vast swath of American technology and every system that relies upon it would go dark for months or even years, some fear — essentially sending the country back to the stone age.
To address this threat, Congressman Trent Franks and former House Speaker Newt Gingrich introduced a bill Tuesday to protect the grid. Called the SHIELD Act, or the Secure High-voltage Infrastructure for Electricity from Lethal Damage, the bill would push the federal government to install grid-saving devices, surge protectors that could save the transformers and power system from EMPs.
Newt Gingrich, the former speaker of the House, was on Capitol Hill this week addressing what he believes is a real threat and could cripple the U.S. power grid.
Gingrich, along with Rep. Trent Franks, AZ, introduced the SHIELD Act, which would encourage strengthening the electric grid in preparation for a major EMP event.
