Laura Geggel reports: During medieval times, bookmakers fashioned the pages and cover of a rare copy of the Gospel of Luke out of five different types of animals: calves, two species of deer, sheep and goat, according to new research.
In addition, one more type of animal left its mark on the cover of this 12th-century book: Beetle larvae likely chewed holes into the leather binding, the researchers said.
Now, researchers are learning unexpected secrets about the manuscript by noninvasively testing the proteins and DNA on the book’s pages, the researchers told Live Science.
Rare books — such as this copy of the Gospel of Luke — are difficult to study because they’re fragile, prompting many librarians to bar any research that would harm such manuscripts or their pages.
This rule is all too familiar to Matthew Collins, a biochemist at both the University of York in the United Kingdom and the University of Copenhagen. He wanted to sample parchments — documents made from animal skins — as a way to determine how people have managed livestock throughout history.
When Collins and Sarah Fiddyment, a postdoctoral fellow of archaeology at the University of York, approached librarians at the University of York’s Borthwick Institute for Archives, “we were told that we would not be allowed to physically sample any of the parchment documents, as they are too valuable as cultural-heritage objects,” Fiddyment told Live Science.
But Fiddyment didn’t give up. She spent several months learning how librarians conserve rare parchments, and, surprisingly, found a new method that allows scientists to study these specimens without disturbing them — one that involves an eraser.
Typically, librarians “dry clean” parchments by gently rubbing a polyvinyl chloride eraser against them. This technique pulls fibers off the page, and the resulting debris is usually thrown away.
But Fiddyment realized this debris held valuable clues about the book. By isolating proteins and other biological fragments within the debris, and examining them with a mass spectrometer — an instrument that identifies different compounds by their masses — researchers could learn all kinds of information about the manuscripts, she found.
“This was Sarah’s brilliant idea,” Collins told Live Science in an email. “Oddly enough, I think we relished the challenge.”
It wasn’t long before Fiddyment put this technique into action. A historian bought the aforementioned Gospel of Luke at a 2009 Southeby’s auction. An analysis of its “prickly” style of script indicated that scribes at St. Augustine’s Abbey in Canterbury, in the United Kingdom, created it around A.D. 1120, Bruce Barker-Benfield, the curator of manuscripts at the Bodleian Libraries at the University of Oxford, told the journal Science.
To learn more about the gospel, the historian contacted Collins. Using Fiddyment’s method, Collins and his colleagues learned that the book’s white leather cover came from the skin of a roe deer— a common species in the United Kingdom. The book’s strap came from a larger deer species — either a native red deer or a fallow deer, an invasive species likely brought from continental Europe after the Normans invaded in 1066.

Another widespread cyber attack is causing massive problems across Europe Tuesday.
Ukraine has been hit particularly hard as government and company officials have reported serious intrusions across the Ukrainian power grid, banks and government offices. The country’s prime minister says that the cyber attack affecting his country is “unprecedented,” but “vital systems haven’t been affected.”
Ukrainian Deputy Prime Minister Pavlo Rozenko on Tuesday posted a picture of a darkened computer screen to Twitter, saying that the computer system at the government’s headquarters has been shut down.
There’s very little information about who might be behind the disruption, but technology experts who examined screenshots circulating on social media said it bears the hallmarks of ransomware, the name given to programs that hold data hostage by scrambling it until a payment is made.
“A massive ransomware campaign is currently unfolding worldwide,” said Romanian cybersecurity company Bitdefender. In a telephone interview, Bitdefender analyst Bogdan Botezatu said that he had examined samples of the program and that it appeared to be nearly identical to GoldenEye, one of a family of hostage-taking programs that has been circulating for months.

Siri will be the conductor of a suite of devices, all tracking your interactions and anticipating your next moves.
Apple Inc. will still sell an iPhone, but expect the device to morph into a suite of apps and services, enhanced with AI and AR, part of a ‘body area network’ of devices, batteries and sensors.
Christopher Mims writes: It’s 2027, and you’re walking down the street, confident you’ll arrive at your destination even though you don’t know where it is. You may not even remember why your device is telling you to go there.
There’s a voice in your ear giving you turn-by-turn directions and, in between, prepping you for this meeting. Oh, right, you’re supposed to be interviewing a dog whisperer for your pet-psychiatry business. You arrive at the coffee shop, look around quizzically, and a woman you don’t recognize approaches. A display only you can see highlights her face and prints her name next to it in crisp block lettering, Terminator-style. Afterward, you’ll get an automatically generated transcript of everything the two of you said.
As the iPhone this week marks the 10th anniversary of its first sale, it remains one of the most successful consumer products in history. But by the time it celebrates its 20th anniversary, the “phone” concept will be entirely uprooted: That dog-whisperer scenario will be brought to you even if you don’t have an iPhone in your pocket.
Sure, Apple AAPL 0.45% may still sell a glossy rectangle. (At that point, iPhones may also be thin and foldable, or roll up into scrolls like ancient papyri.) But the suite of apps and services that is today centered around the physical iPhone will have migrated to other, more convenient and equally capable devices—a “body area network” of computers, batteries and sensors residing on our wrists, in our ears, on our faces and who knows where else. We’ll find ourselves leaving the iPhone behind more and more often.
Trying to predict where technology will be in a decade may be a fool’s errand, but how often do we get to tie up so many emerging trends in a neat package?
In the wake of the U.K.’s most recent terrorist attacks, its prime minister is talking tough on Internet regulation, but what she’s suggesting is impractical.
Tragically, there have been three major terrorist attacks in the U.K. in less than three months’ time. After the second, in Manchester, May and others said they would look into finding ways to compel tech companies to put cryptographic “back doors” into their services, so that law enforcement agencies could more easily access suspects’ user data.
May repeated her stance in broaders terms Sunday, following new attacks in London. “The Internet, and the big companies” are providing “safe spaces” for extremism, she said, and new regulations are needed to “regulate cyberspace.” She offered no specifics, but her party’s line, just days from the June 8 national election, is clear: a country that already grants its government some of the most sweeping digital surveillance powers of any democracy needs more and tougher laws to prevent terrorism (see “New U.K. Surveillance Law Will Have Worldwide Implications”).
The trouble is, this kind of talk ignores how the Internet and modern consumer technology works. As Cory Doctorow points out in a detailed look at how you would actually go about creating services with cryptographic holes, the practicalities of such a demand render it ludicrous bordering on impossible. Even if all of the necessary state-mandated technical steps were taken by purveyors of commercial software and devices—like Google or Apple, say—anyone who wanted to could easily skirt their restrictions by running open-source versions of the software, or unlocked phones.
That isn’t to say that May and the Conservatives’ general idea that the government should be able to probe user data as part of an investigation should be dismissed out of hand. The balancing act between national security and digital privacy has become one of the central themes of our digital lives (see “What If Apple Is Wrong?”). And while there are advocates aplenty on both sides, simple answers are hard to come by. Read the rest of this entry »
“We’ve gone to a modern [broadcast] system that has a lot of places where stuff can happen without permission,” says Thomas W. Hazlett, who’s the FCC‘s former chief economist, a professor at Clemson University, and author of the new book The Political Spectrum: The Tumultuous Liberation of Wireless Technology, from Herbert Hoover to the Smartphone. “And we have seen that the smartphone revolution and some other great stuff in the wireless space has really burgeoned…That comes from deregulation.”
So-called net neutrality rules are designed to solve a non-existent problem and threaten to restrict consumer choice, Hazlett tells Reason’s Nick Gillespie. “The travesty is there’s already a regulatory scheme [to address anti-competitive behavior]—it’s called antitrust law.”
Greater autonomy and consumer freedom led to the development of cable television, the smartphone revolution, and the modern internet. While we’ve come a long way from the old days of mother-may-I pleading with the FCC to grant licenses for new technology, Hazlett says, “there’s a lot farther to go and there’s a lot of stuff out there that’s being suppressed.”
He points to the history of radio and television. Herbert Hoover and Lyndon Johnson exercised extraordinary control over spectrum allocation, which they used for their own political and financial gain. With liberalization, we now have hundreds of hours of varied television programming as compared to the big three broadcast networks of the ’60s, an abundance of choices in smartphone providers and networks as compared to the Ma Bell monopoly, and more to come.

“We face a possible future where people not only ignore scientific evidence, but seek to eliminate it entirely,” warns the march’s mission statement. “Staying silent is a luxury that we can no longer afford. We must stand together and support science.”
From whom do the marchers hope to defend science? Certainly not the American public: Most Americans are fairly strong supporters of the scientific enterprise. An October 2016 Pew Research Center poll reported, “Three-quarters of Americans (76%) have either a great deal (21%) or a fair amount of confidence (55%) in scientists, generally, to act in the public interest.” The General Social Survey notes that public confidence in scientists stands out among the most stable of about 13 institutions rated in the GSS survey since the mid-1970s. (For what it’s worth, the GSS reports only 8 percent of the public say that they have a great deal of confidence in the press, but at least that’s higher than the 6 percent who say the same about Congress.)
The mission statement also declares, “The application of science to policy is not a partisan issue. Anti-science agendas and policies have been advanced by politicians on both sides of the aisle, and they harm everyone—without exception.”
I thoroughly endorse that sentiment. But why didn’t the scientific community march when the Obama administration blocked over-the-counter access to emergency contraception to women under age 17? Or dawdled for years over the approval of genetically enhanced salmon? Or tried to kill off the Yucca Mountain nuclear waste storage facility? Or halted the development of direct-to-consumer genetic testing? Read the rest of this entry »
The GBU-43/B Massive Ordnance Air Blast (commonly known as the Mother of All Bombs) is a large-yield conventional (non-nuclear) bomb, developed for the United State military by Albert L. Weimorts, Jr. of the Air Force Research Laboratory. At the time of development, it was touted as the most powerful non-nuclear weapon ever designed.
The GBU-43/B Massive Ordnance Air Blast (MOAB pronounced /ˈmoʊ.æb/, commonly known as the Mother of All Bombs) is a large-yield conventional (non-nuclear) bomb, developed for the United States military by Albert L. Weimorts, Jr. of the Air Force Research Laboratory. At the time of development, it was touted as the most powerful non-nuclear weapon ever designed. The bomb was designed to be delivered by a C-130 Hercules, primarily the MC-130E Combat Talon I or MC-130H Combat Talon II variants.
Since then, Russia has tested its “Father of All Bombs“, which is claimed to be four times as powerful as the MOAB.
The U.S. military dropped the largest non-nuclear bomb in eastern Afghanistan on Thursday just days after a Green Beret was killed fighting ISIS there, a U.S. defense official confirmed to Fox News.
The GBU-43B, a 21,000-pound conventional bomb, was dropped in Nangarhar Province.
The MAOB (Massive Ordinance Air Blast) is also known as the “Mother Of All bombs.” It was first tested in 2003, but hadn’t been used before Thursday.
Aside from two test articles, the only known production is of 15 units at the McAlester Army Ammunition Plant in 2003 in support of the Iraq War. As of early 2007, none of those were known to have been used, although a single MOAB was moved to the Persian Gulf area in April 2003.
On April 13, 2017, a MOAB was dropped on a target in the Nangarhar Province inside Afghanistan. It was the first non-testing use of the bomb.
The basic operational concept bears some similarity to the BLU-82 Daisy Cutter, which was used to clear heavily wooded areas in the Vietnam War and in Iraq to clear mines and later as a psychological weapon against the Iraqi military. After the psychological impact of the BLU-82 on enemy soldiers was witnessed, and no BLU-82 weapons remained, the MOAB was developed partly to continue the ability to intimidate Iraqi soldiers. Pentagon officials had suggested their intention to use MOAB as an anti-personnel weapon, as part of the “shock and awe” strategy integral to the 2003 invasion of Iraq. Read the rest of this entry »
The Defense Department still uses 8-inch floppy disks and computers from the 1970s to coordinate nuclear forcesPosted: April 3, 2017
Mackenzie Eaglen writes: Dale Hayden, a senior researcher at the Air Force’s Air University, told an audience of aerospace experts earlier this month that proliferation of antisatellite technology has put America’s communications networks at risk. “In a conflict, it will be impossible to defend all of the space assets in totality,” he said. “Losses must be expected.”
It has never been easier for America’s adversaries—principally Russia and China, but also independent nonstate actors—to degrade the U.S. military’s ability to fight and communicate. Senior military officials have expressed grave doubts about the security of the Pentagon’s information systems and America’s ability to protect the wider commercial virtual infrastructure.
The U.S. Navy, under its mission to keep the global commons free, prevents tampering with undersea cables. But accidents—and worse—do happen. Last year a ship’s anchor severed a cable in the English Channel, slowing internet service on the island of Jersey. In 2013 the Egyptian coast guard arrested three scuba divers trying to cut a cable carrying a third of the internet traffic between Europe and Egypt. “When communications networks go down, the financial services sector does not grind to a halt, rather it snaps to a halt,” warned a senior staffer to Federal Reserve Chairman Ben Bernanke in 2009. Trillions of dollars in daily trading depends on GPS, which is kept free by the Air Force.
There are now an estimated 17.6 billion devices around the world connected to the internet, including more than six billion smartphones. The tech industry expects those numbers to double by 2020. That growth is dependent, however, on secure and reliable access to intercontinental undersea fiber-optic cables, which carry 99% of global internet traffic, and a range of satellite services.
The U.S. military is working on ways of making them more resilient. For instance, the Tactical Undersea Network Architectures program promises rapidly deployable, lightweight fiber-optic backup cables, and autonomous undersea vehicles could soon be used to monitor and repair cables. In space, the military is leading the way with advanced repair satellites as well as new and experimental GPS satellites, which will enhance both military and civilian signals.

Rob Pyers was a laid-off grocery bagger who learned to code on YouTube. Now the website he runs, the California Target Book, is shining a light on spending by politicians, their campaigns, and outside groups.
Rob Pyers didn’t set out to bring transparency to establishment politics. In fact, he didn’t even have any programming experience before he built the electronic systems for the California Target Book, a go-to resource for political transparency in the state. He initially came to Los Angeles with aspirations of becoming a screenwriter, but ended up stuck in his day job, bagging groceries. Then Walgreen’s laid him off, and he needed something else to do.
After joining the Target Book, Pyers taught himself how to code, mostly by watching YouTube videos. Two years later, the 41-year-old has built its systems from the ground up, and now runs the website from his cramped West Hollywood one-bedroom. He is often the first to publicize major donations and new candidates, making his Twitter feed invaluable to campaign consultants and journalists alike.
Pyers, who describes himself as “95 lbs of concentrated tech geek,” has become an expert on pulling data from hundreds of voter databases, election filings, and campaign finance disclosures. He’s done all this despite the fact that the state’s main resource for campaign information is an inaccessible hodgepodge of ZIP archives and tables that even the current Secretary of State has called a “Frankenstein monster of outdated code.”
“California’s Cal-Access website is notorious for being just sort of an ungodly, byzantine mess,” says Pyers. “If you have no idea what you’re doing, it’s almost impossible to get any useful information out of.”
The state is currently working on a multi-million dollar upgrade to the site, with an expected rollout in 2019. But while the government builds its new system, the Target Book has already proven its worth. During one 2016 Congressional race, the L.A. Times used Pyers’ data to reveal that candidate Isadore Hall may have misused hundreds of thousands of dollars of campaign cash. Read the rest of this entry »
Dissidents are using USB drives to smuggle information into authoritarian regimes.
“The struggle for freedom is one that used to be about who has more guns. Now information is a key component in making sure the government doesn’t get away with winning the day with its narrative and pushing what governments tend to do, which is the use of fear to control the population.”
But if you were looking for something truly disruptive at SXSW, look no further than a group of activists using tech to spread information to citizens oppressed by authoritarian regimes.
“The people out there they don’t have satellites, they don’t have internet, they have nothing,” says Abdalaziz Alhamza who escaped Syria and co-founded Raqqa is Being Slaughtered Silently. “To be stuck with only ISIS propaganda, it will affect them.”
Alhamza and dissidents from Eritrea, Afghanistan and Cuba were brought together by the Human Rights Foundation (HRF) for a panel discussion called “The Real Information Revolution.” Reason caught up with the group at the HRF booth on the convention floor, centered around a large wall of Kim Jong Un faces with USB ports for mouths. Attendees were invited to donate USB drives into the display. The drives will later be smuggled into North Korea after being wiped and filled with films and information from the outside world.

The U.S. stands to lose 80 million jobs to automation.
Thomas Phippen reports: The robotic labor revolution is coming quickly, and the workforce may not be able to adapt without long periods of unemployment, according to economists at the Bank of England.
“Economists should seriously consider the possibility that millions of people may be at risk of unemployment, should these technologies be widely adopted.”
“Economists should seriously consider the possibility that millions of people may be at risk of unemployment, should these technologies be widely adopted,” BOE economists Mauricio Armellini and Tim Pike wrote in a post on Bank Underground, a blog for bank employees, Wednesday.
Artificial intelligence (AI) “threatens to transform entire industries and sectors,” the authors write, arguing that with the speed of industries adopting technological developments won’t give the labor force time to adjust. Read the rest of this entry »
Brainchild of artist and actor Jack Millard causes stir along highway in Arizona
(1) Titan launch test from Cape Canaveral, only first stage engine tested, 2nd stage only a dummy, engine with 300,000 lbs thrust successful (2) News In Brief – Berlin mayor Willy Brandt arrives in U.S., speaks in English (3) “Virginia” – Fort Meyer VA funeral of 6 bodies returned by Russia, crew of plane shot done by Russia, no word of other 11 crew missing (partial newsreel).
1959: The United States successfully test-fires its first Titan I intercontinental ballistic missile. The threat of global nuclear holocaust moves from the plausible to the likely.
Tony Long The Titan I was not the first ICBM: Both the United States and Soviet Union had already deployed ICBMs earlier in the 1950s (the Atlas A by the Americans, the R-7 by the Russians). But the Titan represented a new generation, a liquid-fueled rocket with greater range and a more powerful payload that upped the ante in the Cold War.
The Titan that the U.S. Air Force successfully launched from Cape Canaveral featured a two-stage liquid rocket capable of delivering a 4-megaton warhead to targets 8,000 miles away. A 4-megaton detonation, puny by today’s standards, nevertheless dwarfed the destructive power of the atomic bombs dropped on Japan.
The Titan’s range meant that, firing from its home turf, the United States was now capable of hitting targets in Eastern Europe, the western Soviet Union and the Soviet Far East.
The first squadron of Titan I’s was declared operational in April 1962. By the mid-’60s, five squadrons were deployed in the western United States.
The missiles were stored in protective underground silos, but had to be brought to the surface for firing. The Titan II, which began appearing in large numbers during the mid-’60s and eventually supplanted the Titan I, would be the first ICBM that could be launched directly from its silo.
Today, ICBMs can be launched from silos, from mobile launchers and, most effectively, from submarines. Read the rest of this entry »
President Trump, you have a golden opportunity to employ the qualities your supporters believe you have to challenge the Pentagon and the defense aerospace industry to do something that hasn’t been done for many decades: Provide just what the US needs to defend itself on time and at a reasonable cost. The F-35 is a mess and you know it, Mr. President. So does Mad Dog. The F-35 has taken far too long to develop, as costs and serious doubts about its capabilities mount. Meanwhile, the US military air fleet ages, and costs to maintain it and keep it combat ready increase. The F-35 has its defenders but, honestly, those defenders are people with a vested interest in keeping the program going — either military pilots who fear that without that plane, they’ll have no ride at all, or people who have been intimately involved in developing and overseeing the program through its long and tortured history.
“Here’s how to do it. First, tell the Pentagon to define a short, clear set of specifications. I can give you one as an example they can start from. Tell them to do this in 90 days. They can do it — there are really smart people who have been thinking about this a lot for a long time.”
The basic problem with the F-35 is grounded in its fundamental conception: A common airframe that serves all three of the US flying services — Air Force, Navy and Marines. The US faced a “smart” solution to fighter procurement like this once before in notoriously “smart” Secretary of Defense Robert McNamara’s plan to develop a common Air Force and Navy fighter program in the 1960s. The two services knew that their needs were very different then and successfully fought that proposal. By the 1990s, when the F-35 program had its inception, they’d apparently forgotten all that.
“Absolutely no representatives from any contractor who wants to participate in the project should be allowed to participate in drafting these specification. You define the first and most important specification: Each aircraft is to cost no more than $60 million. Yes, you read that right. $60 million. It can be done. Don’t let anyone tell you it can’t.”
But I won’t rehash that history here. Instead, let me propose a straightforward solution. Don’t totally cancel the program. The F-35 does have some good characteristics and all three services and our allies who have committed to the program should take some of them. The F-35B, with its short take-off and vertical landing capabilities is the only possible near-term or even intermediate-term solution for the Marines’ need to replace the rapidly-aging Harrier upon which they depend. The stealth but especially the incredible smarts built into the basic design of the F-35 can and should be used by the Air Force and Navy in strike missions for which those qualities make it a superior weapon.
You will be told that reducing the numbers of F-35s we buy will increase their unit cost. That is true to some extent, but at some point we have to cut our losses and do what’s best for the overall, long-term defense budget and the nation’s defense.
Both the Air Force and the Navy need a “backbone” warplane that is a fighter first, but that can do a decent job in the strike role and do it in significant numbers (which means at a reasonable cost). (They also need a backbone generally when it comes to the defense contractors. Give it to them.) Both services did a good job in procuring such planes during the era of the “teen series” fighters: The F-16 for the Air Force, and the F-18 for the Navy.
Here’s how to do it. First, tell the Pentagon to define a short, clear set of specifications. I can give you one as an example they can start from. Tell them to do this in 90 days. They can do it — there are really smart people who have been thinking about this a lot for a long time. Absolutely no representatives from any contractor who wants to participate in the project should be allowed to participate in drafting these specifications. You define the first and most important specification: Each aircraft is to cost no more than $60 million. Yes, you read that right. $60 million. It can be done. Don’t let anyone tell you it can’t.
Second, allow any contractor who wants to participate two years to build a flying prototype at their own expense. Two years. And the contractors pay for it. It can be done. Modern rapid prototyping, materials and computer design make this possible. Don’t let anyone tell you it doesn’t. Read the rest of this entry »
MiG-35 Demo is Both Product Debut and Contrast of Russian and Western Doctrine in the F-35 Era.
Tom Demerly reports: In a widely publicized event on Thursday, Jan. 26, 2017 the Mikoyan-Gurevich Design Bureau (MiG) parented by United Aircraft Corporation officially demonstrated the new MiG-35 to the Russian government. A subsequent demonstration for export customers was carried out today Jan. 27.
Russian President Vladimir Putin is reported to have viewed the first demonstration via remote video due to poor weather in the region.
The new MiG-35 (NATO reporting name: “Fulcrum Foxtrot”) is a greatly upgraded aircraft based on the earlier MiG-29 airframe. Significant upgrades on the MiG-35 include a completely new fly-by-wire flight control system, vastly improved cockpit, substantially upgraded avionics and an overall design philosophy that provides an enhanced degree of operational autonomy on the MiG-35 compared to earlier Russian combat aircraft. The MiG-35 will also integrate precision-guided targeting capability for air-to-ground weapons, a rarity in previous Russian air-ground doctrine.
There is a significant engine upgrade on the new MiG-35. The aircraft uses two impressive Klimov RD-33OVT engines fitted with bi-directional thrust vectoring nozzles. This contrasts aircraft like the current Russian Su-35 and the U.S. F-22 Raptor that only use single-axis vertical thrust vectoring.
This marks a fascinating departure from previous Soviet-era combat aircraft capabilities while retaining the Russian penchant for lower unit cost in exchange for numerical superiority, a doctrine that has pervaded Russian military thinking for the entire century.
The Russians have always traded unit capability for numerical superiority, relying on the hope that quantity would beat quality in a major conflict. Interestingly, this doctrine has shifted moderately toward a centrist mix of quality and quantity apparently in search of the best solution for indigenous use as well as attracting export buyers.
The new MiG-35 is an example of this shift. Read the rest of this entry »
The boxer crabs and sea anemones have an awesome mutualistic relationship. Although the anemones are not required for their survival, the crabs use them for personal defense and in return the anemones get a free ride that increases their chances of snatching tasty morsels of floating food.
Some crabs have been known to live without anemone friends and others use sponges or coral instead. Still, the image of a brave little crab waving two stinging sea anemones about is supremely cute and literally quite cheering.
Mike Fabey and Kris Osborn report: The U.S. Navy is moving at warp speed to develop lasers with more lethality, precision and power sources as a way to destroy attacking missiles, drones aircraft and other threats.
“We’re doing a lot more with lasers,” Rear Adm. Ronald Boxall, director, Surface Warfare Division, said earlier this month at the annual Surface Naval Association national symposium.
The Navy plans to fire a 150-kw weapon off a test ship within a year, he said. “Then a year later, we’ll have that on a carrier or a destroyer or both.”
And the kind of power needed to power such a weapon won’t come with a simple flip of a switch.
“The Navy will be looking at ships’ servers to provide three times that much power,” says Donald Klick, director of business development, for DRS Power and Control Technologies. “To be putting out 150 kws, they (the laser systems) will be consuming 450 kws.”
That is more than most currently operational ships are designed to accommodate, at least when they are conducting other tasks. “Few power systems onboard ships can support sustained usage of a high-powered laser without additional energy storage,” noted a recent Naval Postgraduate School paper titled “Power Systems and Energy Storage Modeling for Directed Energy Weapons”.
The paper said, “The new DDG-1000 may have enough electrical energy, but other platforms … may require some type of ‘energy magazine.’ This magazine stores energy for on-demand usage by the laser. It can be made up of batteries, capacitors, or flywheels, and would recharge between laser pulses. The energy magazine should allow for sustained usage against a swarm of targets in an engagement lasting up to twenty minutes.
The DDG 1000 is built with what’s called a total ship computing environment, meaning software and blade servers manage not just the weapons systems on the ship but also handle the radar and fire control software and various logistical items such as water, fuel, oil and power for the ship, industry officials said.
The ship’s integrated power system, which includes its electric propulsion, helps generate up to 78 megawatts of on-board electrical power, something seen as key to the future when it comes to ship technologies and the application of anticipated future weapons systems such as laser weapons and rail guns. The ship’s electric drive uses two main turbine generations with two auxiliary turbine generators which power up two 35-megawatt advanced induction motors, developers explained.
Ideally, it would charge up as fast as it discharges, allowing for indefinite use (as long as there is ship’s fuel to expend). Low maintenance, high safety, and long lifespan are other desirable characteristics.
DRS Power and Control Technologies is one of the companies which is developing a specialized energy source. “We have enough for well over 100 shots before we go to recharge,” DRS’s Klick said during a break at SNA, pointing out there’s even a mode for continuous recharge. “If you’ve got power this kind of power, you don’t go Winchester.” Read the rest of this entry »
