The emp threat: fact, fiction, and response (part 1) by yousaf m butt monday, january 25, 2010 a nuclear weapon explodes high above the us, unleashing a deadly electromagnetic pulse (emp) that almost instantly knocks out much of our electrical grid. (any high-altitude emp attack must be conducted at an altitude of 20 miles or above) at 25 miles, the area of the earth's surface within line of sight of the blast, and thus theoretically exposed to the e1 pulse, would have a radius of some 440 miles. The nuclear emp blasts could be fired on long- or short-range missiles, a high-altitude jet strike, or even a high-altitude balloon russia, china, and north korea now have the capability to conduct a nuclear emp attack against the us, the book states. The e1 component of high-altitude nuclear emp is dependent upon the gamma ray output of the weapon e1 is dependent upon several aspects of the gamma ray output the gamma ray output of the bomb can often be increased by sacrificing some of the total energy yield. Any nuclear detonation above 25 miles will cause a high altitude emp (electromagnetic pulse) a nuclear weapon detonated at an altitude of 200 miles could affect all unprotected electrical equipment within the continental united states.
The abrupt pulse of electromagnetic radiation usually results from certain types of high energy explosions, especially a nuclear explosion, or from a suddenly fluctuating magnetic field. How north korea could wipe out electrical networks across the us with a high-altitude emp blast north korea warns of 'super-powerful' electro-magnetic pulse attack on us. A high-altitude electromagnetic pulse (hemp) weapon is a nemp warhead designed to be detonated far above the earth's surface. This widespread emp effect is referred to as high-altitude emp or hemp test data from actual high-altitude nuclear explosions is extremely limited only the united states and the soviet union conducted atmospheric nuclear tests above 20 kilometers and, combined, they carried out fewer than 20 actual tests.
Aaronson, whose institute represents all investor-owned us electric companies, said in testimony that electromagnetic pulse is a concern and could be caused by a high-altitude nuclear blast or a. Concerns over north korea's ability to launch emp attack experts disagree over the threat from a high-altitude nuclear blast and its resultant electromagnetic pulse doug mckelway reports from. A nuclear emp attack could be carried out with a single nuclear weapon detonated at high altitude or a few weapons set off 200 miles above the earth the nuclear emp blasts could be fired on long- or short-range missiles, a high-altitude jet strike, or even a high-altitude balloon. A high-altitude nuclear emp attack is relatively easy to execute it doesn't require much of the advanced technology that a nuclear missile aimed at a city needs and a high-altitude nuclear blast can still do tremendous damage even if it's not targeted precisely.
Newt gingrich has been warning the nation of the danger of an electromagnetic pulse (emp)—a burst of radiation created by a high-altitude nuclear explosion. Ations following an attack against the united states that includes high-altitude nuclear detonations the program approach involves estimating the effects of high-altitude emp. An emp is a high-intensity burst of electromagnetic energy caused by the rapid acceleration of charged particles in an attack, these particles interact and send electrical systems into chaos in. A nuclear electromagnetic pulse (commonly abbreviated as nuclear emp, or nemp) is a burst of electromagnetic radiation created by nuclear explosionsthe resulting rapidly changing electric and magnetic fields may couple with electrical and electronic systems to produce damaging current and voltage surges.
A commission to assess the threat from high altitude electromagnetic pulse (emp commission) was established by congress in fy2001 after several experts expressed concern that the us critical. The united states is vulnerable to a devastating electromagnetic pulse event caused by a high-altitude nuclear blast or solar superstorm, according to a recently published book peter pry, a.
An emp attack by a high-altitude nuclear explosion is also a realistic possibility, though not certain all that's needed is a single nuclear warhead - one that doesn't even require the capability to re-enter earth's atmosphere. Altitude electromagnetic pulse (hemp) attack and to seek suitable ways to deal with the threat the author undertook this paper as an attempt to contribute to the on-going national security dialogue that seeks to balance ends with appropriate ways and means while preserving an. When north korea said on september 3rd that it had developed a hydrogen bomb, adding that it could be used for a super-powerful high-altitude electromagnetic pulse (hemp) attack, america's. United states from electromagnetic pulse attack (note that the new title no longer includes the phrase high altitude, and adds the new word attack) continues with the same membership, and the secretary of defense is authorized to appoint a new.
