    The Navy’s electromagnetic railgun

    The Navy’s electromagnetic railgun

    Interesting weapon. No explosives needed. Pure kinetic energy.

    The Navy is evaluating whether to mount its new Electromagnetic Rail Gun weapon aboard the high-tech DDG 1000 destroyer by the mid-2020s, service officials said.


    The DDG 1000's Integrated Power System provides a large amount of on board electricity sufficient to accommodate the weapon, Capt. Mike Ziv, Program Manager for Directed Energy and Electric Weapon Systems, told reporters at the Navy League's 2015 Sea Air Space symposium at National Harbor, Md.


    The first of three planned DDG 1000 destroyers was christened in April of last year.

    Recommendations made eight years ago to prevent catastrophic blackouts...

    GAO Report: US Still Not Prepared for Possible EMP Attack
    May 3, 2016 – Two weeks after North Korea threatened to launch nuclear strikes against the U.S., the Government Accountability Office (GAO) reported that the federal government has still not implemented all of the recommendations made eight years ago to prevent catastrophic blackouts caused by an electromagnetic pulse (EMP) attack.
    The recommendations were made in 2008 by the Commission to Assess the Threat to the United States from Electro-Magnetic Pulse Attack (EMP Commission). Although the Department of Homeland Security (DHS) and the Department of Energy (DOE) have taken actions to prepare against an EMP attack, they “have not established a coordinated approach to identifying and implementing key risk management activities to address EMP risks,” concluded a March 24 GAO report. In addition, “DHS has not fully leveraged opportunities to collect key risk inputs – namely threat, vulnerability, and consequence information – to inform comprehensive risk assessments of electromagnetic events,” even though such events “pose great risk to the security of the nation.” The report was requested last July by the Senate Homeland Security and Governmental Affairs Committee as it was looking into the EMP threat posed by Iran and North Korea. In 2008, the commission warned that “a high altitude nuclear explosion is one of a small number of threats that can hold our society at risk of catastrophic consequences.” If such an attack were to cause a nationwide blackout lasting as long as a year, up to 90 percent of the American people could die due to starvation, disease and societal collapse.


    That apocalyptic scenario is not as far-fetched as it might seem, according to former CIA director James Woolsey. “On March 9, North Korean dictator Kim Jong Un, a paranoid psychopath, displayed a nuclear missile warhead he threatens to launch against the Unites States and its allies. “The public is being misled by the White House, some so-called ‘experts’ and mainstream media casting doubt on whether the Great Leader’s threat is real,” Woolsey and Peter Vincent Pry, a former CIA analyst and executive director of the EMP Task Force on National and Homeland Security, wrote in an April 24th oped published in the Washington Times. “The president and the press is missing, or ignoring, the biggest threat from North Korea – their satellites,” which are “now in south polar orbits, evading many U.S. missile defense radars and flying over the United States from the south, where our defenses are limited. “Both satellites – if nuclear armed – could make an electromagnetic pulse (EMP) attack that could black out the U.S. electric grid for months or years, thereby killing millions.” “Congress has known for over a decade, since 2004 when the EMP Commission delivered its first report, about the existential threat to the United States from electric grid vulnerability. Yet nothing has been done to protect the grid,” Pry wrote in a March 28 blog post.

    The GAO report noted that besides an EMP attack, naturally occurring geomagnetic disturbances (GMD) could also severely damage the nation’s electrical grid. Since it is “not feasible or cost-effective to protect all infrastructure assets across the electricity sector,” the commission “specifically recommended that DHS and DOE prioritize nodes that are critical for the rapid recovery of other key sectors that rely upon electricity to function, including those assets that must remain in service or be restored within hours of an EMP attack,” the report stated. However, “DHS and DOE have not taken actions to identify key electrical infrastructure assets as required given their respective critical infrastructure responsibilities under the NIPP [National Infrastructure Protection Plan],” according to GAO.

    After interviewing federal employees and industry experts, GAO auditors concluded that securing the grid is not a top federal priority even though the consequences of an EMP/GMD even could be catastrophic nationwide. “According to officials within the DHS Office of Policy, addressing EMP risks has generally been a lower priority compared to other risks due to a combination of differing opinions on the likelihood of these events and their expectation that other federal agencies will be involved in responding,” such as the Department of Defense. Counterterrorism and counterdrug efforts “remain higher priorities for the department,” the GAO report noted, even though “not securing the electric grid from electromagnetic events could result in the loss of electrical services essential to maintaining our national economy and security.”

    US defense secretary says Russia is 'nuclear saber-rattling'
    May 3, 2016 — U.S. Defense Secretary Ash Carter blasted what the U.S. and its allies see as Russian aggression in Europe, saying Tuesday that Moscow is "going backward in time" with warlike actions that compel an American military buildup on NATO's eastern flank.
    "We do not seek to make Russia an enemy," Carter said at a ceremony to install a new head of the military's U.S. European Command and top NATO commander in Europe. "But make no mistake: We will defend our allies, the rules-based international order, and the positive future it affords us," he said. Carter's remarks reflect U.S. aggravation with Moscow on multiple fronts, including its intervention in eastern Ukraine, its annexation of Crimea in 2014 and what Carter called Russian efforts to intimidate its Baltic neighbors — countries the United States is treaty-bound to defend because they are NATO members.

    Carter said the "most disturbing" Russian rhetoric was about using nuclear weapons. "Moscow's nuclear saber-rattling raises troubling questions about Russia's leaders' commitment to strategic stability, their respect for norms against the use of nuclear weapons, and whether they respect the profound caution that nuclear-age leaders showed with regard to brandishing nuclear weapons," he said. The end of the Cold War with the collapse of the Soviet Union in 1991 was thought to have virtually ended the prospect of nuclear conflict with Moscow. But the speeches at Tuesday's change-of-command ceremony emphasized the possibility of history repeating itself, or at least ending a period of warmer U.S.-Russian relations.

    Senior White House officials said the U.S. and its partners were shifting into a new phase focused on military deterrence to Moscow. Additional NATO forces that will rotate through countries on Russia's eastern flank will be enough to defend NATO countries if Russia were to attack, said the officials, who requested anonymity to discuss internal deliberations. To that end, the U.S. plans to add a third U.S. Army combat brigade in Europe in the coming year as part of a $3.4 billion initiative, Carter said. On Monday, he said NATO is considering establishing a continuous rotation of up to 4,000 troops in the Baltic states and possibly Poland.

    That force, which could include some U.S. troops, is among options expected to be considered at a NATO defense meeting in June. U.S. officials said they were encouraging other NATO members to commit troops to the force as well. But U.S. attempts to control or direct Russia haven't fared well. The U.S has been unable to end Russia's occupation of parts of Ukraine and support for separatist rebels. And Washington is desperately seeking Moscow's help to enforce a cease-fire in Syria between the Russian-backed government and Western-supported rebels, and eventually usher President Bashar Assad out of power. On both fronts, the United States has been running into brick walls with the Russians. U.S. officials said that they had "explicitly compartmentalized" the various issues the U.S. is discussing with Russia. Yet it's unlikely that Russia's government sees it that way.

    Deadlier than a ninja possum...

    Squid-inspired Camouflage, Hypervelocity Railguns and Tank Transformations
    June 07, 2016 — What was science fiction just a few years ago is now among the Pentagon's most innovative new technologies.
    The Defense Department's chief technology officer, Steve Welby, sat down with VOA to talk about some of the craziest and most remarkable breakthroughs being developed in military laboratories across the country. Here are some of our favorites.

    Sense of touch

    A program called Hand Proprioception and Touch Interfaces (HAPTIX) is making robotic arms even more true to life. "The next frontier is the work going on in programs like HAPTIX, where we're not just trying to restore the function of those limbs, but actually trying to restore the sensory function as well," Welby said. HAPTIX will be able to send information from the prosthetic limb back into the body, much like the nerve endings on fingers tell the brain how hard the hand is squeezing something, or how rough or smooth a surface is. Volunteers who thought they'd never have their sense of touch back are already experimenting with prototypes. "It's just an amazing idea that we're now being able to map that kind of two-way feedback into the nervous system," Welby said. "Being able to touch people's lives in these kinds of ways — it's really rewarding work."

    Squid-inspired camouflage

    Ever want to just disappear? A new type of camouflage will help soldiers blend in with their backgrounds, and even disguise themselves from infrared cameras. Researchers are focusing on a protein called reflectin, which is found on the skin of certain species of squid and octopus, and allows them to very quickly mimic their surroundings and virtually vanish from sight. Reflectin-based invisibility stickers could help the military control the reflectivity of people and equipment, and perhaps even allow thermal management. "We're now learning from nature and applying it in new ways," Welby said. "There are now some interesting prototypes that folks are playing with."

    Faster than a speeding bullet

    The Navy is using electromagnets to shoot projectiles at hyperspeed, many times faster than any bullet can be shot out of other guns. "That's important because it might allow one to be able to defend oneself against, perhaps, missiles that are coming at you, to be able to shoot them out of the air," Welby said. The new technology could also provide the ability to attack an enemy long before the enemy could engage U.S. service members. The gun creates the electromagnetic field used to fire a projectile by shooting an electric pulse down one negatively charged rail and one positively charged rail. It can fire a projectile at a speed of up to 7,400 kilometers per hour.

    ‘Language of the mind’

    Since 2001, more than 250,000 U.S. service members have struggled with memory loss from traumatic brain injuries and degenerate brain problems. And it's not just a problem on the battlefield. Millions of people around the globe are affected by memory disorders from injuries and diseases such as Alzheimer's every year. The military is looking to help people retrieve memory through wearable systems that could restore function in parts of a damaged brain. "We're now decoding the language of the mind, how we actually store facts," Welby said. "It's an entirely new field, areas that we just didn't think were possible before." Researchers are working to understand the way the brain forms memories so that they can identify and correct problems when pathways to memories become damaged. Welby is among many who have had friends and family suffer from memory loss, and he says the hope that the research offers is "enormous."

    I have often worried about this. It is not only military sources we should worry about, but extraterrestrial sources as well. Particularly, our sun. I think we need to have a contingency plan for the event that our electricity and electromagnetic data disappears. That not only means the electricity humans depend on, but the data stored on hard drives, tapes and memory chips. Think about it. We have only had the luxury of these things for a brief moment in human history, and we have evolved to depend almost entirely on it. We are incapable of fully understanding what kinds of extraterrestrial phenomenon can destroy it. If we rely solely on the electrical structure we are currently living on, we are $#@!ED if something ever happens to it. We need to start constructing some redundancy within our infrastructure, and we need to do it fast.

    Another article on the rail-gun

    The US Navy continues testing and development of its next generation railgun, and the little science fiction geek inside me gets excited every time it’s mentioned.

    Raytheon is playing its part in bringing the railgun to life, supplying the US Navy with the railgun’s pulse power containers. The combined collection of pulsed power modules provide enough energy to allow electromagnetically charged rails to launch a projectile at speeds over mach 6, or just over 4,500 mph.

    I have read that they hope to use similar technology to launch payloads into low earth orbit. Maybe even manned vessels.
