    Physicist question

    Why in the world wouldn't the US deploy a large number of EMP capable bombs to use in the Middle East, China, Russia, North Korea, etc? It would seem that such a device would effectively incapacitate an enemy quickly and effectively. Is is because of the longer term ramifications of trying to rebuild infrastructure in those areas once they are militarily defeated. Or is it because the scope of such a weapon cannot be controlled and may harm allies? Concern about long term civilian collateral damage as the nation upon whom this is leashed devolves back to the dark ages? This seems like a perfect weapon! Must be a down side somewhere.....

    Ground based emp bombs are expensive and have limited range. The real emp threats come from detonating a thermonuclear explosion above the mesosphere to create a ionic field

    Vertigosol - I was thinking in terms of an atmospheric detonation - just deploying the bombs closer to the arena of action - perhaps from a sub...

    I think most of the people in the world ie... Middle east, North Korea, China,... aren't addicted to using electronics and electricity like the USA. An EMP won't hurt them like it would the USA.
    An Opium farmer in Afghanistan won't even notice an EMP went off let alone anyone in North Korea.

    But it would seemingly disable their military: radars, jets, SAMs,surface vessels, tanks - anything with electronics. I would imagine that command and control would be seriously impaired as well. It seems that this would be seriously crippling to an opponents ability to respond to an attack.

    No Area of operation near the conflict zone would be needed either since it would be delivered via space via ICBM or similar

    Any emp (ie nuclear bomb) would be highly destructive and could easily take out low earth orbit satellites. Those could be considered acts of war by other countries not near where the intended blast is set off

    Me being me... and worrying about things that have little probability of happening.... due to being smack dab in the middle of Detroit and Chicago .... or as Stealers Wheel put it... " Stuck in the middle with you "... ( a little humor this morning ) . Especially since Detroit has the largest population of Allah Akbar's...here in the US .
    I have contemplated the effects of even small dirty bomb blast and the effects... it sure seem to be the perfect weapon to harm ( US ) our lifestyle and install terror. If your already living in the stone age like the terrorists.... well they would just lose cell phone comm's....?

    Here is how it works: keep in mind that altitude is " everything " ...
    (so as usual I was worrying about a possible terror event that has even less of a possibility of happening ) we would be in bad shape if attacked by a super power that can deliver ICBM , as said above.

    The first is a nuke's invisible burst of gamma rays, a form of light typically emitted by the "hottest and most energetic objects in the universe," according to NASA. A small fraction of a bomb's energetic yield – between 0.1% and 0.5% – is emitted as gamma rays. These slam into air molecules, knock off electrons, and accelerate the negatively charged particles to about 90% of the speed of light.

    Earth's magnetic field then shuttles many of these high-speed electrons toward the planet's poles in a corkscrew-like pattern. The electrons respond to this movement by letting off their newly acquired energy as a powerful soup of electromagnetic radiation, including radio waves.

    This is a nuclear electromagnetic pulse. It happens within a fraction of a microsecond, and the surge of energy can overload or "shock" sensitive electronic devices – especially the kinds we heavily rely on today.

    "[T]he radiation can be collected by metallic and other conductors at a distance, just as radio waves are picked up by antennas," according to an unclassified 1977 report from the Department of Defense and Department of Energy.
    "The energy from the EMP is received in such a very short time, however, that it produces a strong electric current which could damage the equipment," it said. "An equal amount of energy spread over a long period of time, as in conventional radio reception, would have no harmful effect."

    When EMP passes through metal objects like a phone, computer, or radio, they can "catch" this incredibly powerful pulse. This can generate a rogue current of electricity that moves through a modern device's tiny circuits and can disrupt or even destroy them. Power transmission or telecommunications equipment, meanwhile, can overload from the excess current, spark, and fail for miles around.

    If you've ever turned on a microwave oven and noticed your phone's Wi-Fi or Bluetooth connection momentarily drop out, you've experienced disruptive electromagnetic waves – and had a very small taste of what could happen with an EMP.

    The intensity of a nuclear detonation's EMP is about 30,000 to 50,000 volts per meter – thousands of times greater than the one your microwave bleeds off.

    Reference material is from " Business Insider " magazine.


    Sorry just looking to share.... not take the thread sideways !

    Cost is one downside. Profit may be another. Which companies would be interested in producing such a weapon? How much profit could they charge?

    A MUCH, MUCH more likely scenario is a natural calamity, such as a coronal mass ejection. Our power grid is extremely vulnerable because we only have a few of the huge transformers as replacements. The cost and space real estate is apparently too great to have enough on standby.

    Lots of ways to get the snot kicked out of us!
