what would be cool if u could make emps bombs like the end of

EMPs actually pose a pretty significant threat to a country's national security, and would be a formidible weapon in a technologically advanced world. The nanosecond-long burst would short out all sensitive electronic devices, and if repeated, all electronics eventually fail.

This would mean no communication, no power grid, no radar, nuclear meltdowns, and crashed planes and cars (b/c of the embeded chips used so widely). It would not destroy everything, nor knock them back to the stone age, but would cause trillions of dollars of damage and take a ton of time to repair and recover from. In short, it could effectively bring an entire civilization to its knees, disabling it enough for a total takeover.

Near ground level nuclear explosions make very strong but short-ranged magnetic fields. But at high altitudes (20 miles+), the gamma rays have enough area of relatively thin air to reach spreads of 1000 miles or more (depending on detonation strength and alt.) before reacting with the EM field.

Some very expensive shielding has been devised to harden military equipment against EMPs, but the civilian devices and networks that actually run a civilization are totally vulnerable to this type of attack. Much more research is needed to find a cost effective shielding.

Very scary stuff.

What EM field?

An EMP (electromagnetic pulse) is just a very short burst of intense EM radiation, particularly around the millimeter range IIRC. Anything that shields EM (e.g. faraday cages) works against EMP.

A nuclear bomb generates EMP but it has to be very big or very near for it to be effective (since energy density is inversely proportional to the square of distance).

Since there's life in this thread I mays well put in my 2 cents...
There could be a EMP generation tech to research and the unit it allows could be a one-use cruise-missile device. To balance this have it so that it is sigificantly expensive to construct an EMP device and it can only be used against units to disable (but not destory) them. And as a final balance have a EMP shield tech which allows shield upgrades at a cost.

With a sufficiently strong EMP, your Faraday cage can overload; it won't act like a perfect conductor, and thus won't protect perfectly. You can shield, but it's expensive, and not guaranteed to work if your enemy just uses a bigger bomb.

You may as well add solar and geomagnetic storms to this debate, as they have more damage in recent times (especially to satellite navigation/surveillance/communications) than any man made EMP device.

I can shoot thru any tank armor as long as I have a bigger gun, but sometimes having a bigger gun is difficult to make or use just like a bigger/more energetic EMP is more difficult to generate. There is no all-protecting armor just like there is no all-destorying weapon.

You forgot to factor in energy, sure a few nuke can cover a large area but the field is so spead out that it just dusts the electronics with EMP that's why all the nuclear bomb tests that USSR and USA conducted didn't affect no electronics. It probally had more affect on biological systems than electronic.

Certain militaries, including the US are leading the research into this field so they can disrupt orders of battle by disabling submarines, tanks, etc, anything using electricity.

Hey DarkCloud what issue of PM was the EMP bombs in? But interestingly enough when I was searching the PM site I found an article on optical computers. So by the time EMP tech is perfected, computers probally won't run on electronics anymore and the EMP will have little to no effect on computers.

On a different tangent here: Bush should develop EMP tech instead of an interceptor missle as a SDI. The pulse could disable nukes better than any interceptor can.

So what would you have society do, Krazyhorse? Not develop electronics, and get rid of what we have? Despite your claims, the situation is the same for electronics now as it was for tanks in the 20s and 30s(or whenever any sort of new technology was/will be introduced). What you're doing is the same as telling a runner he might as well give up the race because someone else might run faster.

EMPs will be about as widely used as nuclear bombs are. They don't just take out bombers and battleships, EMPs also scramble hospitals, water treatment plants, and civilian power plants, essentially putting an entire city's population at risk. They are no videogamey equalizer between the 1st and 3rd worlds. At best EMPs will take over the backpack nuke or home-grown anthrax's job as a literary hook in some second-rate terrorist novel.

The Civ series doesn't need any more lame gimmicky units ala CTP. What it needs, as far as WMDs, is a feature so that nukes can be pre-targetted for launch the instant a nuclear strike hits a friendly city. This would allow for a true MAD environment, and provide a considerable deterrant to nuclear attacks.

Hey Goldstein check out this link on M.A.D.

And Goldstein is right about how frequently EMP will be used. If EMP bombs can be built with 1950's tech, then how come all these nations aren't flinging EMP's at each other if it's so easy to generate?

You obviously weren't living in Hawaii in the 60s. The US managed to black out the entire island, IIRC. It wasn't as much of a disaster as it would be today, because less things were computerised. I think I remember war plans calling for only a half-dozen or so nukes detonating at a couple hundred kilometers altitude, and the level of radiation would have been sufficient to knock out any non-hardened devices.

Lord Magnus, an EMP device of effective size is basically an H-bomb. Anything less concentrated would be really hard to launch over your enemy's atmosphere. As of 1999, there were 44 nuclear capable nations in the world (meaning they have nuclear reactors for power or research). But since the early sixties only India and Pakistan have joined the original five member nations of the nuclear club - the United States, Russia, China, Britain and France. In other words, it's expensive and exclusive - the original members were against India's and Pakistan's tests.

And though there is animosity between the two new entrants, and in the past among the first few members, the political situation of the world would not exactly tolerate nations as trigger-happy as the ones in Civ II. Though I have no doubt that any civ or civer would leap at the chance to employ this miracle weapon over exercising restraint.

Where the hell is this coming from? When did I advocate any sort of Luddism? I'm merely pointing out that EMP devices were a part of the nuclear arsenal of the two nuclear superpowers, and that an EMP detonation would cause a large amount of damage to the electronic infrastructure of any developed nation. I'm not even advocating their inclusion in Civ3, so learn to read before you criticise.

Actually, generating a largish EMP requires the use of thermonuclear weapons and the ability to deliver them above the atmosphere, a combination of abilities which only 5 nations have. The reasons EMPs aren't used is the same reason atmosphere-detonated nukes aren't used: they're weapons of mass destruction, and their use will return to bite the user on the ass.

KrazyHorse is right about there being documented real-world effects from US testing over Pacific isles. And in a real war, an EMP would be more tempting to use than just blowing up a city because it avoids the controversial practice of heating up millions of innocent civilians to temperatures hotter than the sun and all the really nasty after-effects such as blindness and radiation sickness. All deaths caused would be "second-hand" and unintentional.

And the shielding, Urban Ranger, would have to be a bit more filled in than a Faraday cage, at least that's what my source (The Electromagnetic Pulse)has been saying. Though the shield would only need to be millimeters thick, it would have to be a continuous welded sheet. I was shocked, but it said this cost $1000 (1986 US) per square meter to do this.

The electronic hardening is a lot cheaper because it only deals with making the sensitive components more sturdy, though presently are not reliable enough to...rely on. Though I'm sure (or hope) that will change.

Urban Ranger, the US and other nations indeed did open-air tests in the sixties. After Carl Sagan and others popularized the idea of a possible nuclear winter from the dust lofted into the atmosphere by multiple explosions, public reaction made underground testing the only accepted alternative (though Sagan may have had complete abolition of testing in mind). There was also some radiation contamination of milk and produce in the midwestern US from cloud deposition and a miniscule remnant of that radiation still circulates today.

Various non-proliferation treaties and test bans have been agreed upon within the nuclear club since then, and now fuels the debate between them and the nuclear club wannabes. Theclub members don't want to allow more testing but they won't disclose their testing knowledge to those nations either. Admittedly, I think India could better allocate it's resources by providing for it's billion not too well off inhabitants instead of it's testing program, but it does seem unfair for them to be denied this information because they arrived on the nuclear scene a few decades too late.

The desire to keep these nuclear secrets locked up though, is not to short India or Pakistan, but to keep it away from "rogue nations" such as Iraq or Libya that would dare to use them without fearing the consequences. This also kept US companies from exporting supercomputers for years b/c it could be used to simulate nuclear explosions. But "supercomputers" of yesterday are basically the PCs of today, or a few linked up in parallel. The US companies have been upset b/c this puts them at a disadvantage compared to foreign competition and I believe Congress has been lifting the restrictions a bit more each year to compensate for the rate of advance in chip technology. Well, I've ranted far too long and drifted off-topic so I'll stop here.

The cover story of the September 2001 Pepular Mechanics is about EMP bombs. It says that the first major test of an American electromagnetic bomb will be next year. It also says that very high frequency pulses could go through vents in Faraday Cages. It also says that terrorists could build a basic EMP bomb for an estimated $400. So the barbs might get these if they were in the game.
