Boston Dynamics shows a quieter, more thoroughbred AlphaDog to DARPA and the Marines (video)
When we last saw Boston Dynamics' AlphaDog (aka LS3), it was strutting through outdoor trials with the subtlety of a nuclear missile: for all that noise, it might as well have been holding a "shoot here please" sign broadcasting American soldiers' positions to everyone in the forest. Several months later, the company is showing both DARPA and the Marine Corps a refined version of its load-carrying robot that has clearly been through a few rounds of obedience school. While we still wouldn't call the four-legged hauler stealthy, it's quiet enough to avoid the role of bullet magnet and lets nearby troops chat at reasonable volumes. And yes, there's new tricks as well. AlphaDog can speed up its travel over difficult surfaces and move at up to a 5MPH jog, all while it's following a human squad. DARPA and the Marines recently began testing and improving the robot over a two-year period that should culminate in an Advanced Warfighting Experiment with the Marines to test viability under stress. If AlphaDog passes that bar, there's a good chance many on-foot soldiers will have a mechanical companion -- and quite a weight lifted off of their shoulders.
Army seeking proposals for casualty-carrying UAVs
Combat is a grizzly business, and despite the best efforts of medical evacuation crews, it's not always feasible to send rescue teams into the fray. The US Army is seeking to address this with "autonomous vertical takeoff and landing (VTOL) unmanned aircraft systems (UAS)" (read: drones) for dropping off medical supplies and picking up injured troops. In its latest request for research and development proposals, the Army calls not for new tools, but for the repurposing of current aircraft to do the job. Preferred candidates in the already unmanned class include the A160 Hummingbird and the K-MAX, while one of the suggestions for remote-control modification is the infamous Black Hawk. Makes the AR.Drone seem a little wimpy, doesn't it?
DARPA calls on Cubic Corporation to develop frighteningly accurate One Shot XG sniper rifle
Sighting in a target through the scope of a high-caliber rifle can be a bit more complicated than it sounds -- snipers have to account for cross-winds, range and a whole host of external factors that could put their projectile off course. It isn't easy, and the required calculations can seriously slow down a shooter's time to trigger. The solution? High tech laser-equipped sniper scopes, of course. DARPA has actually been working on this problem for quite some time, and calls its' project One Shot. Previous iterations of the targeting system helped shooters increase their chance of hitting their mark by a factor of four, but suffered from short battery life, range finder accuracy errors and overheating problems. DARPA is putting its faith into Cubic Corporation to overcome these faults, awarding the firm with a $6 million contract to develop a "compact observation, measurement and ballistic calculation system" that it calls the One Shot XG. Like its predecessors, the XG is designed to give the shooter a offset aim point to counteract the environmental conditions that would impact bullet trajectory. DARPA is hoping to see ten weapon or scope-mountable field devices within 15 months. Consider this fair warning, Segway bots.
Fire Shadow missile can remain aloft for six hours before obliterating a moving target (video)
If we were making a list of terrifying airborne war machines, this would probably rank near the top. You certainly won't want to be targeted by the Fire Shadow, but from the safety of a web browser, it's impossible not to marvel at the craft's versatility. Manufactured by French developer MBDA, the Fire Shadow missile is designed to strike a stationary or moving object on command. But unlike some other UAVs, this ingenious rig can remain airborne for up to six hours before it's assigned to destroy a large vehicle (and its occupants) from a nearly vertical angle of attack. Tipping the scale at less than 440 pounds (about 200 kilograms), it has a range of approximately 62 miles (100 kilometers) and is described by MBDA as being "low cost." The British Army is said to have taken delivery of the missile in March, and will begin testing in Sweden later this year, but you can see it action today in the demo video after the break.
US Navy deploys SeaFox submarines to Persian Gulf for universal mine control
Tasked with mine detection and eradication in the Persian Gulf, the US Navy has sent a fleet of unmanned submarines to help keep the Strait of Hormuz open in Iran. Dubbed the SeaFox, each vehicle houses an underwater TV camera, sonar and a dose of explosives. Tipping the scales at less than 100 pounds, the subs are about four feet in length and are controlled via fiber optic cable that sends the live feed back to the captain of each ship. SeaFoxes can dive to depths of 300 meters and boasts a top speed of six knots. The units are thrust into action from helicopters, small rubber boats and off the rear of minesweepers and are capable of disposing of the aforementioned weapons of both the floating and drifting sort. There is one small catch: the $100,000 submarine destroys itself in the process, making each successful trek a suicide mission of sorts.
Lockheed Martin Stalker drone stays airborne 48 hours using laser power, all-seeing eye gets literal (video)
Aerial drone designers have been pushing hard to get devices that can stay airborne for days. After all, what's the point of having an observer that routinely lets its guard down? Lockheed Martin must have this question forever etched in its collective mind, as it just completed tests of a modified Stalker drone that was continually charged by laser power beamed from a ground-based source. The LaserMotive-built test was admittedly conducted in a wind tunnel, not a wind-swept battlefield, but it kept the drone aloft for more than 48 hours and was so efficient that it might even have gone indefinitely, if it weren't for staff intentionally bringing the trial to a halt. The true test is coming next, when Lockheed Martin and LaserMotive fly the drone on laser power outdoors. Should the Stalker sail the friendly skies for long enough, it could help usher in an era of UAVs that can spot intruders at all hours -- a little too close to the aircraft's name for comfort, perhaps, but potentially vital for Special Operations troops that might not have to put themselves in danger. You can check the underpinnings of both the laser power system and the Stalker in videos after the break.
BAE Systems speaks about unmanned ASTRAEA: no reason it can't stay in air 'for weeks'
BAE Systems' ASTRAEA isn't a new concept -- the company's been playing up its unmanned potential for quite some time now -- but it's all seeming entirely less pie-in-the-sky now that the Farnborough Airshow has kicked off. Typically, UAVs are thought to be smaller, drone-type apparatuses; these things are typically used in military exercises where remote gunfire or reconnaissance is required. Clearly, it's about time someone asked the obvious: "Why?" Lambert Dopping-Hepenstal, Engineering Director Systems and Strategy, Military Air and Information at BAE and ASTRAEA Program Director recently spoke at the aforesaid event, noting that this particular aircraft could "open up a new market." He continued: "Current search and rescue aircraft are limited by human endurance, however with a UAV there's no reason why they can't stay up for weeks." Sadly, he also affirmed that there aren't any plans to ship actual humans up in the air without a pilot onboard, but if you're rich and mettlesome enough to pull it off yourself... well, be sure to send us the video. Also, Godspeed.
BAE Systems designs hard composite solar cells: could act as structure of UAVs, piece of soldier's gear
BAE Systems revealed that it's working on hardy, high-capacity solar cells that could power unmanned vehicles and even attach to an individual soldier's gear. According to Darren Buckle, a manager from BAE Systems' Advanced Technology Center, the cells are geared toward smaller, often airborne, military units, where weight is at a premium. The system, still in the development stage, could offer up power for heavy endurance unmanned air vehicles, provided the cells are made sensitive enough to absorb energy in less sunny situations -- something that the company's England-based engineers are currently contending with.
Lockheed Martin F-35 Lightning II stealth fighter cockpit demonstrator hands-on (video)
We spend hundreds of hours on board a variety of airplanes each year, most often en-route to a trade show or product launch event, but occasionally we have a rare opportunity to hop on board military aircraft, to test out unrelated products, or, even more unusually, to take a seat behind the yoke. Sadly that's not what we're doing today -- well, not exactly. We are taking a closer look at the F-35 fighter jet at Lockheed Martin's Fighter Demonstration Center just outside our nation's capital, but, being in the middle of a corporate complex, there's no actual Lightning II on hand. We were able to take a simulated ride, however -- this isn't your ordinary 4D sickness-inducing amusement park thrill. The F-35 is by far the most advanced Lockheed jet to date, with updated radar, all-internal weapons, improved tracking systems, 360-degree infrared coverage with a visor readout, and a full-stealth design, not to mention the incredibly capable glass cockpit powered by more than 9.3 million lines of software code, and an overall smoother experience for pilots that could end up spending shifts of 12 hours or longer in flight. The F-35 has already seen plenty of field time in the US, with more than 500 flights already in 2012, and it's set to make its way to the UK armed forces next week and the Netherlands later this year, but while the aircraft is quite familiar to the pilots tasked with flying it, the public hasn't had an opportunity to experience Lockheed's latest airborne warrior. We flew a simulated mission within a grounded duplicate of the flyable F-35 cockpit, and the capabilities and improvements are quite clear -- you definitely don't want to encounter an F-35 from a previous-generation aircraft. The dual 8 x 10-inch touch-enabled displays combine to give you 8 x 20 inches of real estate, with dedicated modules for the weapons systems, targeting, and navigation easily accessible -- you can also move them to different panels depending on your current objective. A pair of joysticks at the left and right side provide direct access, letting you move a cursor to track enemy crafts or ground-based targets as well, and a very slick heads-up-display mounted in the helmet provides infrared mapping and instrument readouts. Overall, it seems to be an incredibly powerful system. Unfortunately, the mock-up on display here isn't accessible to the public, but you can join us for a behind-the-scenes look just after the break.%Gallery-160208%
LIPC weapon combines lasers and lightning, proves soldiers are a bunch of nerds
The problem with laser weapons is this -- they need a lot, a lot of power. Seriously. Some of those big, plane-mounted prototypes choke down enough juice to power a whole city. Not so with the Laser-Induced Plasma Channel weapon being developed by researchers at Picatinny Arsenal. While still using plenty of electricity, this more moderately specced laser is just powerful enough to strip electrons off the air molecules around it generating a thin filament of plasma. Its not the high-intensity laser pulse that does the damage, though. Instead, the channel of plasma is used as a conduit for a high-voltage blast of electricity. That laser-assisted bolt of lightning could disable vehicles, people and even IEDs. There are plenty of obstacles, including making the weapon rugged enough for battlefield use and reliable enough to keep the plasma channel from leading the blast of electricity back into the laser and damaging it. Now, if only we could find the video that still above was taken from.
US Army breaking up with A160 Hummingbird drone-copter, says it's too high maintenance
It's not me, it's you. The US Army's dalliance with Boeing's A160 Hummingbird drone got one step closer to Splitsville after the military branch issued a stop-work order for the project. Initially scheduled to see action in Afghanistan starting this July, the chopper-drone turned plenty of heads thanks to a DARPA-developed Argus-IS imaging system with a 1.8-gigapixel camera capable of spying on ground targets from 20,000 feet. The honeymoon period between the Army and the A160 is apparently over, however, thanks to a host of issues. These included wiring problems as well as excessive vibration that caused an A160 to crash earlier this year due to a transmission mount failure. The problems not only increased risk and caused delays, but also led program costs to helicopter out of control -- a big no-no given Uncle Sam's recent belt-tightening. In the meantime, the Army is reportedly checking out the K-MAX, though it's important to note that this unmanned chopper specializes in cargo and doesn't have the A160's eyes.
Military hunting smartphone safety to hold off enemy bugs, spooks
Ah, smartphones -- the delightful little slates carry our contacts, our content -- even our cash, and they still fit right in our pockets. No surprise then, that a lost or stolen phone can be a minor disaster -- or a major security risk (just ask the President). Now that soldiers are packing them to send GPS coordinates or situational images in the field -- on top of using them at home -- DARPA has enlisted security company Invincea to fortify the devices. Its first effort, encrypting OS files and filling the memory of a lost phone with worthless data, has already been deployed to 3,000 troops in Afghanistan. Its next target is to cloister apps into virtual rooms within the OS, locking off access to sensitive parts of the phone like its GPS or contact lists. That would keep any nasty bits of malware from potentially gaining root privileges so soldiers can fight, and Facebook, without compromise.
NICT's Daedalus creates beautiful 3D visuals to map out nasty cyber attacks (video)
There's nothing pretty about a cyber attack taking over an organization -- or, there wasn't, until NICT crafted this thing. Daedalus, christened as a "cyber attack alert system," is a 3D visualization system that currently monitors some 190,000 IP addresses across Japan. Rather than forcing a human to comb through a punishing amount of data, the visualizer turns into an organized stream of lines that can be viewed and zoomed in on from any angle. You can see networks and subnets, as well as patches of used and unused IP addresses; taking it a step further, the system lights up when an attack is sensed (for example, an IP pinging an unused IP as a virus spreads with reckless abandon). DigInfo reports that the system could find a home in educational and enterprise applications, but there's no word on how much it'll cost to deploy en masse. Per usual, the video demonstration awaits you after the break.
Northrop Grumman Unveils US Navy's MQ-4C BAMS Triton unmanned aircraft
If Broad Area Maritime Surveillance, or war gadgets are your bag, then things just got real. Northrop Grumman has just unveiled the MQ-4C BAMS Triton, the latest addition to the US Navy's Maritime Patrol and Reconnaissance Force. The spy plane was more than four years in development, has a wingspan of 130.9 feet, and is able to cover more than 2.7 million square miles in a single mission. As you will have been unable to avoid noticing, the unmanned aircraft definitely inherited some of the RQ-4 Global Hawk's dome-like DNA, and will edge towards active service after completing functional requirement reviews and system development and demonstration flights. Want to bone-up on the full spec? Hit the more coverage link for the numbers. In the meantime, we're wondering if they might extend the research.
Attack of the drones: US Navy picks Linux for its unmanned VTOL aircraft control system
Disagreement between passionate Windows and Mac OS diehards have caused many a kerfuffle on the Interwebs. When it comes to the tactical control system of the US Navy's autonomous vertical take-off-and-landing craft, however, the military branch is putting its money on a different operating system. The Navy just awarded a contract worth nearly $28 million to Raytheon Intelligence and Information Systems to transition its VTOL drones to using its own flavor of good, old Linux. Eventually, the Navy plans to have 168 Northrop Grumman MQ-8B Navy Fire Scout drones rocking the OS as part of its fleet. The Register reports that the move was likely made for security reasons following a malware attack on the Air Force's Windows-based drone system last year. Add Samsung's recent inclusion into the Platinum ranks of Linux's core supporters and you really can't blame fans of the operating system if they decide to wear shades while pondering its future.

Boeing Phantom Eye takes first flight towards unmanned marathon espionage (video)
Boeing could've aimed a little higher for the Phantom Eye's first successful test flight. And by that, we mean the addition of one Billy Zane in a form-fitting purple leotard fending off baddies as the plane taxied the runway. None of that happened because, well, the aerospace brainiacs behind this unmanned bulbous beauty tend to err on the side of sense, not showy drama. Tant pis. Missed opportunity for ostentatious absurdity aside, the engineering outfit did manage to log in a near-perfect round trip for the hydrogen-powered spycraft, reaching an altitude of 4,080-ft after its early morning take off from Edwards Air Force Base on the first of the month. The still in-development vessel's return to terra firma wasn't without hiccups, as it did sustain minor damage to its landing gear. With further refinements, though, engineers hope to push the autonomous plane even further, prolonging the duration of the flight to an eventual four days and doing so without the need for refueling (or tending to humans). It's an obvious leap forward for cloak-and-dagger government interests, but really, it's all about the recovery of magic skulls. Right? Right. Check out the video after the break.
Navy plans ship-based LTE for close-quarters communication
Bandwidth is a precious commodity on military vessels. Ships in the US Navy fleet are generating more data, but the pipe it's getting pumped through isn't getting any larger. What's more, with limited connectivity options on the table, the sea-faring military wing is missing out on all the smartphone and app store fun. Rather than turn green with envy, or turning their dress whites is for camouflage cargo pants, the Navy is beefing up its mobile tech arsenal, beginning with the U.S.S. Kearsarge, U.S.S. San Antonio and U.S.S. Whidbey Island. The ships will serve as test beds for a nautical LTE system, with a range of about 25 miles. The 4G network will serve as a localized platform for wirelessly feeding data to sailors, as well as a way for the enlisted to connect to the outside world. On the backend, the Marines are working on a new satellite broadband service that should be able to provide ships with 300 megabits of shared bandwidth. Satellite internet and off-grid LTE might induce yawns in some, but they're certainly a major part of modernizing our fighting forces. For more info, check out the source link.
Army spy blimp to launch within weeks: 300 feet long, $500 million, 'multi-intelligent'
It can't go faster than 34MPH and it's already a year late for its planned deployment in Afghanistan, but Northrop Grumman's Long Endurance Multi-Intelligence Vehicle (LEMV) is now set for its maiden flight. The test run is scheduled for sometime between June 6th and 10th over Lakehurst, New Jersey, whose residents ought to be forewarned that it is not a solar eclipse or a Death Star, but simply a helium-filled pilotless reconnaissance and communications airship that happens to be the size of a football field. After floating around for a while, the giant dirigible is expected to journey south to Florida, where it'll be fitted to a custom-built gondola that will carry the bulk of its equipment, and by which time her enemies hopefully won't have come into possession of an air force.
Laser-toting MAV can find its way in tight spaces, might eventually hunt you down (video)
A perpetual weakness of MAVs (micro air vehicles) is their frequent need for hand-holding in anything other than a wide-open or very controlled space. If they're not using GPS or motion sensors to find their locations, they can't turn on a dime the way a human pilot would. Adam Bry, Abraham Bachrash and Nicholas Roy from MIT's CSAIL group haven't overcome every problem just yet, but they may have taken combat drones and other pilotless aircraft a big step forward by giving them the tools needed to fly quickly when positioning isn't an option. Uniting a laser rangefinder with an existing 3D map of the environment -- still 'cheating,' but less dependent -- lets the prototype flyer find the distance to nearby obstacles and steer clear even at speeds that would scare any mere mortal MAV. Ideally, future designs that can create their own maps will be completely independent of humans, making us think that MIT's references to "aggressive" autonomous flight are really cues to start hiding under the bed.
Navy looks into UV cloak for stealth aircraft
The Navy's invested good money in the F-35 Joint Strike Fighter, which obscures radar waves and redirects engine heat to evade recognition by infrared sensors. But that stealth flier is still vulnerable to another type of detection: UV sensors. The Pentagon recently began soliciting proposals to develop a device that cloaks aircraft from ultra-violet detection systems. The hope is that such a technology could shield aircraft from missile seekers that scan the sky for telltale "UV silhouettes." According to the call for research, the solution could involve a device that disperses a cloud of quantum dots or other materials to veil jet fighters in a shapeless mass of UV shadow. Given that this is a rather daunting task, it's not surprising that the development timeframe and projected cost are still up in the air.
