    Aside from the 20,000 artillery pieces North Korea has, an EMP attack by the US on North Korea would render the majority of North Korea's Defense capability useless: jet fighters, missiles with any sort of electronics, communications, etc. But if a submarine is submerged, is it vulnerable to an EMP (Electromagnetic Pulse) and does water/depth the submarine is at limit the EMP weapon. It is possible that an EMP attack on submarines might cause it to blow up as no telling what would happen. Plus the fact the submarine might have trouble surfacing. Here is an interesting report on Global...

    Explanation: A new sky is becoming visible. When you look up, you see the sky as it appears in light -- electromagnetic radiation. But just over the past year, humanity has begun to see our once-familiar sky as it appears in a different type of radiation -- gravitational radiation. Today, the LIGO collaboration is reporting the detection of GW151226, the second confirmed flash of gravitational radiation after GW150914, the historic first detection registered three months earlier. As its name implies, GW151226 was recorded in late December of 2015. It was detected simultaneously by both LIGO facilities in Washington and Louisiana,...

    When compared to the costs of the grid going down for an extended time, a few billion dollars is a bargain A report by the Center for Security Policy (CSP) paints a dire picture regarding the vulnerability of the U.S. (and by extension—Canadian) electricity grids from man-made or natural electromagnetic disturbances. The CSP and others in the national security sector have been beating this drum for a number of years, but unfortunately all too little is being done about the risks. William Forstchen even wrote a compelling must-read novel on this topic—One Second After—back in 2009. In 2004, the Commission...

    BILLIONAIRE HEDGE FUND MANAGER: Of All The Things That Are Likely, Nothing Is Scarier Than An Electromagnetic Pulse Myles Udland July 30, 2014 Plasmasphere - Wikimedia Commons Hedge fund managers often like to opine on various topics that are largely unrelated to investing. In his latest lengthy quarterly letter to clients, Paul Singer of Elliott Management spent some time discussing a phenomenon that caught our attention and the attention of many others. It's the danger posed by an electromagnetic pulse. Singer writes that an electromagnetic pulse is the "risk that stands way above the rest in terms of the scope...

    Israel Could Send Iran ‘Back To The Stone Age’ with Electromagnetic BombAn American electromagnetic bomb being tested (photo credit: screen capture botanyfamily/Youtube) Israel could destroy Iran’s electric network with a specially designed electromagnetic bomb in the event of a military conflict between the countries, The Sunday Times reported on Sunday. An electromagnetic bomb of this sort would be detonated above the ground, creating an electromagnetic pulse that would “disrupt all the technological devices working on the ground,” an American expert was quoted as saying to the London paper. The use of the new technology by Israel was brought up in...

    European researchers said Thursday they have created a device invisible to a static magnetic field that could have practical military and medical applications. Fedor Gomory and colleagues in Slovakia and Spain designed a cloak for a direct current, or dc, magnetic field that is static and produced by a permanent magnet or coil carrying a direct current. DC magnetic fields are used in MRI imaging devices, in hospitals and in security systems, such as those in airports. The researchers' device, described in a study in Friday's edition of the journal Science, features a cylinder with two concentric layers. While the...

    Ubiquitous in science fiction, rail guns are a hot area of military research in real life too. But will we ever really get to use them the way people in science fiction do? And could rail guns be used for a non-violent reason — inexpensively launching payload into space? Halo Reach ends with your Spartan taking up a mounted rail gun to destroy an incoming Covenant ship. Rail guns are the basis for a funny aside in Mass Effect 2. They're used in Babylon 5 and Stargate Atlantis and The Last Starfighter. And they're a devastating hand-held weapon in the...

    It's bewildering. Pathetic. Frightening. And it seems that the mainstream media avoids talking about it for fear that Americans will panic. Well, Americans ought to be panicking -- anything to get them to bang on Congress's door and force our representatives to immediately act on the pending legislature now in Congress called the SHIELD Act -- a bill based on the previous HR 5026 -- that unanimously passed in the House of Representatives on June 9, 2010. The disaster I am referring to is an electromagnetic pulse (EMP), which can easily be caused either by Mother Nature as a geomagnetic...

    A Silicon Valley company is assembling a sprawling network of electrical contraptions across California that its investors hope will prove many seismologists wrong and become a valuable public-safety tool that reliably predicts earthquakes. The project, called QuakeFinder, involves installing some 200 five-foot-tall sensors near fault lines to measure changes in underground magnetic fields and detect electrically charged particles in the air. The theory behind it is that changes in electromagnetic fields can foretell quakes. The science behind QuakeFinder, however, is disputed. Most seismologists dismiss it as bogus and have long concluded that forecasting earthquakes is impossible. The U.S. Geological Survey,...

    Electronic devices dominate modern combat. Warfighters depend on access to the electromagnetic spectrum to communicate with friendly forces, track enemy movements, navigate in the fog of war, collect intelligence, and perform many other vital functions. Electronic warfare is the military specialty concerned with denying enemy forces use of the spectrum while assuring that friendly forces have unfettered access. Airborne jammers are essential to the successful conduct of most electronic warfare missions. Jammers are used to prevent enemy radars and communications devices from functioning effectively by dominating the frequencies in which such systems operate. This is accomplished by either overpowering the...

    A theoretical dream for decades, the railgun is unlike any other weapon used in warfare. And it's quite real too, as the U.S. Navy has proven in a record-setting test today in Dahlgren, VA. Rather than relying on a explosion to fire a projectile, the technology uses an electomagnetic current to accelerate a non-explosive bullet at several times the speed of sound. The conductive projectile zips along a set of electrically charged parallel rails and out of the barrel at speeds up to Mach 7. The result: a weapon that can hit a target 100 miles or more away within...

    Recent tests at NAS Lakehurst, N.J., should have builders of the USS Gerald R. Ford (CVN-78) sleeping more easily. The Navy’s risky bet in the design of the Ford—its reliance on an all-electric replacement for the steam catapult—appears to be paying off. Problems and delays with the electromagnetic aircraft launch system (Emals) last year were a threat to the carrier, because its design and construction reached a point where reverting to steam would have been difficult and expensive. With Emals in mind, the Ford-class features a much more powerful electrical generation and distribution system than the predecessor Nimitz-class ships, along...

    Israel has developed a counter-insurgency system that could see through walls. Israel's Camero has developed a system that could penetrate walls and identify enemy operatives. Camero has developed the Xavier 400 system, which uses electromagnetic pulses to allow operators to see everything within an adjacent room. "This technology saves lives," Cameron vice president David Gazelle said. Executives said Xavier, the size of a laptop computer, has already been deployed around the world. In November 2009, the three-kilogram system facilitated the rescue of a kidnapping victim in an unidentified foreign country. Xavier was said to be based on a multi-channel ultra-wideband...

    One of the more intriguing technologies spotted at this week’s Navy League Sea-Air-Space Expo was General Atomics’ electromagnetic rail cannon. The company has been working for a number of years with the Office of Naval Research on a 200-nautical mile gun system. In a parallel effort, they’ve been developing a smaller, pulse-power technology demonstrator, called the Blitzer, for ship defense against anti-ship cruise missiles and small boat swarms. Two million amps launch a guided projectile at twice the speed of a conventional gun, but at much lower cost than the usual surface-to-air missile systems on most naval ships. General Atomics...

    What appears to be of particular concern to the EMP commission is the scepter of terrorist groups or so-called “rogue” nations carrying out such an attack. As outlined by Dr. Pry, one of the commissioners, before a 2005 Senate Subcommittee on Terrorism, Technology and Homeland Security, “[a] nuclear missile concealed in the hold of a freighter would give Iran, or terrorists, the capability to perform an EMP attack against the United States homeland, without developing an ICBM, and with some prospect of remaining anonymous. Iran’s Shahab-3 medium-range missile… is a mobile missile, and small enough to be transported in the...

    WASHINGTON (AFP) – Long suspected of causing brain tumors, mobile phones are now being eyed as key allies in the fight against Alzheimer's disease, US researchers said Wednesday in a study. Researchers at the University of South Florida (USF) found, to their surprise, that 96 mice they zapped twice daily for an hour each time with electromagnetic waves similar to those generated by US mobile (cellular) phones benefited from the exposure. Long-term exposure to the electromagnetic waves in mobile phones wiped out deposits of beta-amyloid -- a protein fragment that accumulates in the brain of Alzheimer's sufferers to form the...

    THE CASE FOR SPACE-BASED DEFENSE The growing interest in nuclear technology by countries such as Iran presages the possibility that one or more nations may attempt to harness such a capability in the form of an electro-magnetic pulse (EMP) attack against the United States, a prominent political scientist has warned. Such a scenario, writes Brian Kennedy of the Claremont Institute in the November 24th edition of the Wall Street Journal, is not far-fetched. "It would require the Iranians to be able to produce a warhead as sophisticated as we expect the Russians or the Chinese to possess. But that is...
