report, for the first time reveals details on how nuclear EMP weapons are integrated into the military doctrines of China, Russia, North Korea, and Iran.


Super-EMP bombs produce gamma rays that generate a peak EMP field of 200,000 volts per meter—enough to fry strategic communications and intelligence systems. China, Russia, and probably North Korea are said to have these arms, according to the commission. The United States has no super-EMP weapons in its nuclear arsenal.

Report made public last week.

When not in use, unplug and cage your electronic gear or risk losing it.

Do not un-cage your electronic gear immediately after a HEMP attack. Wait out the second lay-down.

This scenario offers so much return on investment I can't imagine a bad guy passing up the opportunity to deal a death blow to "The Great Satan".

All good information that was pretty much assumed in the past. Only thing I am surprised about is we don't have an EMP based weapon in our arsenal.

We don't need one. Any nuke of sufficient yield can be used to create NEMP when detonated at the appropriate altitude. Super-EMP is just a renamed Enhanced Radiation weapon. It's a fission-only weapon that allows the radiation to escape from the bomb casing instead of being used to boost the yield or initiate a secondary. Our W-66 warheads from the Sprint Missiles were ER warheads. If we still have some of those laying around awaiting disassembly, they could be used as "super-EMP". But really, it's not necessary. Super EMP is just a buzzword Peter Pry likes to throw around to add more pop to his presentations.

While I support educating people about the threat of NEMP and of course want to see our infrastructure better hardened against it, some of these claims are getting a little nutty. The 200kV/m using 10kt claim seems like a typical Russian exaggeration that Pry is running with because it fits his narrative. Then there seems to be the implication in the article that an aggressor nation could use NEMP and it wouldn't be viewed as a use of nuclear weapons. I find that rather preposterous.

The other issue is when EMP protection is measured in 10s of dB ( ie 60 or 80 dB), saying the field n increased 6 or 12 dB doesn’t ensure failure. And melting electronics components is meaningless hyperbole.

It’s a pretty sloppy written report, with a lot of self referencing ( this is true because I wrote it was true last year.)

200kV/m does seem like a bit of a stretch. 50kV/m was thought for the longest time to be the theoretical limit. Bad news is if that's true it would completely invalidate pretty much anything from the EMP commission report since they were testing to 50kV/m limit.

In many cases as with automobiles they stopped testing at the first sign of adverse reaction to the equipment being tested which they note cases where adverse reactions were noted below 50kV/m.

Like WImountainMan a fission only weapon (think Fat Man / Little Boy) it what's best for producing an EMP. One of the biggest misconceptions it that a massively huge thermonuclear weapon must be detonated to produce an EMP. The exact opposite is true. A thermonuclear weapon can actually cancel out some of the effect by ionizing the air and opposing the Compton effect.

EMP protection really isn't that difficult on a small scale. It's all about attenuation. Soon I'll post a thread on simple cheap EMP protection.

But you have to put your stuff in it and use the lowest setting for 5 seconds to offset the E1 pulse.

Funny but not helpful. An old microwave makes a perfect faraday cage for small items like a vehicles computer.

A microwave oven is about as effective as a faraday cage as it is as a wireless charger for an iPhone. Try it yourself. I just put my AM/FM/SW radio in our microwave and closed the door. It picked up an AM station that is 30+ miles away using only its internal antenna. The reception was barely affected. Then, I put a cell phone in the Microwave and called it. It rang just fine. Ergo, microwave ovens are NOT faraday cages.

I'm sorry but getting radio reception is not the test. Micro ovens keep the microwaves inside. That also means they keep radiation out.

It may not be the best, but it might help in a pinch.

You're right, microwaves are designed to keep the 2.4GHz microwaves inside, but it doesn't mean they keep radiation out. I just demonstrated it doesn't keep 300kHz to 800MHz electromagnetic radiation out.

Did you also notice all of the non-commital language the author used? The article is littered with words like "Possibly" "Maybe" "Similar To" "Potentially" and "Partially". The author has no idea if it'll work or not. They're just guessing.

While the "radio reception test" is not a test that the cage works it is absolutely a test for it not working because the signals in the KHz range are not being blocked.

Your claim that it'll work for car ECUs is probably correct, not because the microwave is an effective faraday cage, but because the ECU doesn't have an antenna long enough for the pulse to induct current into. So it doesn't matter if it's sitting in the microwave, or on the counter next to the microwave. Even the article mentions that:

Quote:
Most of the energy is distributed throughout the lower frequencies between 3 Hz and 30 kHz.
You need an extremely long conductor (like a power line) for a signal with that long of a wavelength to interact with. An 800MHz to 5.8GHz phone antenna will be too short. Either way, the microwave isn't doing anything.

I admit I'm no EMP expert. There are people on this forum that have forgotten more than I'll ever know, but this is pretty basic stuff.

50kV/m is the theoretical limit for a NEMP. Some other types of devices have achieved 200kV/m with non-nuclear localized devices. These are designed for knocking out specific targets such as a communications centers, etc. DHS uses 50kV/m and all their theoretical studies support that.

If an EMP does hit, it will be the end of life as you know it. There will be no food, water, transportation, or fuel available. There will be total chaos and looting/killing for a cookie. Even military intervention will not be available. If you are not already in a safe and secure place with all your ducks in a row you will most likely be dead in 30 days or less. In my opinion I would not worry about saving anything except my ass. Get out of the city now.

No...an microwave is most definitely not EMP protection, something anyone can test for themselves.

Luckily, it probably doesn't matter because as stated:....

It 's funny that folks are worried about their confusers and phones. I have some trashcan cages but have things like night vision scopes, solar motion detector lights, Led flashlights and bulbs, handi talkies, etc. I do have some electronic how to files stored, but those are on a Kindel. Most of my how to stuff is on paper.
