Laser steering system uses liquid crystal to destroy the enemy on the cheap (video)

It might look like a poor man’s game of Pong now, but a new laser steering system coming out of North Carolina State University could make blowing things up Star Wars-style cheaper and more efficient. The setup enlists a series of “polarization gratings” through which a laser beam passes. Each of these gratings, made of liquid crystal applied to a plate of glass, are configured to redirect the light in a particular direction, thus simply steering the laser beam without significantly decreasing its power — with each grating comes a new “steerable” angle. The system’s creators point out its not only hyper accurate, but also less expensive than existing arrangements due to the use of liquid crystal. Apparently the US Air Force is already using the stuff, but don’t expect them to go all Death Star anytime soon.

Apache’s new infrared targeting system spots foes when they fire, doesn’t wait for the smoke

Apache Longbow Attack Helicopter

It just keeps getting harder for America’s enemies to hide from the technological marvel that is the modern US military. A new ground fire acquisition system (GFAS), coming to Apache Attack helicopters next spring, uses infrared sensors to detect muzzle flashes from small arms fire and pinpoint enemy positions to within five meters. Before the sound would have a chance to reach current acoustics-based sensors the source of the shot pops up on the targeting computer, is sent back to commanders in the Operations Center, relayed to ground troops, and fed to other aircraft — by the time they’re able to pull the trigger again combatants may already be on the wrong side of a Hellfire missile. The new system will make spotting opposing forces easier and keep pilots as safe as they can be — at least until missions can be flown from the comfort of their couch.

How Osama Bin Laden Was Found [Terrorism]

In this age of GPS signals, Foursquare check-ins, and iPhone tracking, how did America’s most-wanted man, Osama Bin Laden, stay hidden for almost a decade? A better question would ask how he was found, for that is the reason the world is rejoicing today. More »

Army app store advances, tries to break through bureaucracy’s defenses

Army Marketplace

The Army Marketplace may be mired in bureaucratic muck, but the depot for mobile military apps isn’t simply stagnating in a stack of paperwork somewhere. Developers and commanders are still pushing forward with the project and hoping for the best. There are already 17 apps for Android and 16 for iPhones, created as part of the Apps for the Army contest last year, and designers have whipped up prototypes for the homepage (above) and personalized user pages (after the break) where soldiers can post ideas for apps, request features from devs, and write reviews. The chief of the Army’s Mobile Applications Branch, Lt. Col. Gregory Motes, hopes the Marketplace will make its debut at LandWarNet in August, even if there won’t be any approved smartphones to access it for several months after that. At least the military claim one victory, when its app store launches it’ll already have more titles than TegraZone.

DARPA’s new Space Surveillance Telescope will keep our satellites safe from interstellar debris

What’s that in the sky? A bird? A plane? Oh, it’s just some junk floating around in space, posing major threats to our military’s spy satellites. To help keep an eye on it, engineers at DARPA, MIT and the Air Force have unleashed a new $110 million telescope that’s been in the works for nine years now. The new Space Surveillance Telescope (SST) is capable of delivering wide-angle views of the Earth’s firmament thanks to a curved CCD. This allows for a massive 3.5m aperture and f/1.0 exposure settings, capturing more light in a day that your average scope can in a week. As part of the Air Force’s Space Surveillance Network (SSN), the telescope’s primary task will be to look out for any microsatellites, meteors or other alien droppings moving at the same speed at which the Earth rotates. The system developed its first images earlier this year and the Air Force may eventually place SSTs all over the world, creating a 360-degree surveillance blanket and going a long way toward keeping our spycraft warm, cozy, and safe from galactic hazards.

BPG Werks DTV Shredder test-ride (video)

We first heard of the Shredder back in September, a crazy, treaded contraption that looked fit to appear in the next Starship Troopers film — or maybe a TMNT reboot at least. It’s the product of the overactive mind of Ben Gulak, the guy behind the Uno transforming and self-balancing motorcycle that we saw at CES. When Ben showed us some videos of the DTV Shredder at the show we knew we had to ride it, and so we did, hitting the sand in New Mexico and managing to come away from the experience unharmed and only a little dehydrated. Come on in to check out our experience on both the consumer-friendly Sport and rather brawnier Military edition, both of which could be in production by the end of the year.

Rugged Casio G’zOne Commando official, coming to Verizon on April 28th for $200

We knew it was coming, and now it’s official: Casio’s macho G’zOne Commando is coming to Verizon on April 28th for a price of $200 on-contract. The Commando strays from a long line of durable dumbphones, and is the first ruggedized Android handset on Verizon’s network. In addition to meeting 810G military specifications for water, dust, shock, vibration, salt fog, solar radiation, and temperature extremes, it runs Android 2.2 (Froyo) and has a 3.6-inch (480 x 800) display, 5 megapixel autofocus camera, microSD slot, WiFi, stereo Bluetooth, and a hotspot feature allowing it to share its 3G connection with up to five devices. And, being built like a tank, it also bundles a handful of apps for outdoorsy types, including a compass, pedometer, star gazer, and thermometer. If you’ve never handled a rugged smartphone, you’ll get your chance Thursday when it hits Verizon retail stores. Until then, check out the PR after the break for more details.

US Army developing Android-based smartphone framework and apps

The US Army is calling upon Android app developers to help make military life a little less stressful — and, perhaps, a lot safer. Under a new Army framework known as the Mobile/Handheld Computing Environment (CE), third-party developers will be able to create and submit tactical Android apps, using the military’s CE Product Developer’s Kit. The framework, originally prototyped by the folks over at MITRE, represents the latest phase in the Army’s ongoing campaign to incorporate smartphone technology on the battlefield. Any app operating under the CE system will be interoperable across all command systems, and, as you’d expect, will be tightly secured. The kit won’t be released to developers until July, but the Army has already begun tinkering with its baseline suite of Mission Command apps, which includes tools designed to facilitate mapping, blue force tracking, and Tactical Ground Reporting. On the hardware side of the equation, the Army is planning to deploy a new handheld known as the Joint Battle Command-Platform, or JBC-P. The two-pound JBC-P is essentially a military-friendly smartphone designed to run on a variety of existing radio networks, while supporting the full suite of forthcoming apps. The JBC-P will be tested this October, and will likely be issued on a wider basis in 2013.

SA Photonics high-res digital night vision system makes you look like Hello Kitty’s cyborg cousin

Given, it might make you look like the love child of Robocop and a cartoon kitten, but SA Photonics’ High Resolution Night Vision System (HRNVS) could mean smoother night flights for the US military. The light weight head mounted display couples high resolution imagery and an impressive 82.5 degree field of vision — previous devices offered a range of only 40 degrees. What’s more, it provides clearer peripheral vision, virtually non-existent halo effects, digital image enhancement, and night vision recording. The headset was designed in collaboration with the US Army and the Air Force Research Laboratory, which means these robo Sanrio helmets might actually get some play. Full PR after the break.

KnightHawk 3G network-in-a-box breaks soldiers’ backs, helps them get online anywhere

While it’s easy enough to envision soldiers scaling battlegrounds with portable hotspots in tow, it’s a useless solution for warriors deployed to remote areas that have patchy service to begin with. Enter the KnightHawk 3G, a rugged network-in-a-box that cooks up connectivity in otherwise uncovered areas. The self-contained WCDMA network runs over the 2100MHz spectrum, promising download speeds as fast as 14.4mbps and max upload rates of 5.76mbps. It has capacity for up to 60 simultaneous voice calls and can handle 14 HSPA connections at a time. And it’ll help keep our troops in top shape — you can’t tell from the photos, but that thing weighs 45 pounds.
