DARPA aids our military in myriad ways, from designing one shot, one kill weapons to creating robotic pack mules to carry soldiers' gear. It's also been building tools for soldiers to better survey their environment and identify threats, and its latest such tool is called the Cognitive Technology Threat Warning System (CT2WS). CT2WS is comprised of a 120-megapixel electro-optical video camera with a 120-degree field of view feeding a laptop running cognitive visual processing algorithms. Those algorithms identify potential targets in the video feed, which are shown to a soldier wearing an EEG cap that monitors brain signals. You see, the human brain is particularly good at perceiving threats, and CT2WS looks for the particular brain wave that occurs when we see one. The human component drastically improves the accuracy with which the system can identify enemies from afar. How accurate? Testing in desert, tropical and open terrain showed that without a solider/EEG filter, the system had 810 false alarms out of 2,304 threat events in an hour. Incorporating the filter resulted in only five false alarms per hour, plus it was able to identify 91 percent of the potential targets successfully. Not good enough, you say? Add commercial radar into the mix and the army becomes omniscient -- the system then identified 100 percent of the test targets.

The US Army's not-so-secret Long Endurance Multi-Intelligence Vehicle (LEMV) spy blimp is better at staying hidden than we thought... if unintentionally. Although it was due to fly the friendly skies of Lakehurst, New Jersey in mid-June, Northrop Grumman's usually unmanned surveillance was only just caught floating over the Jersey Shore as part of a maiden flight on August 8th. The conspicuous, delayed test run proved that the LEMV could take off, steer and land smoothly, and started a series of exercises that should culminate in combat trials over Afghanistan at the start of 2013. Northrop's KC Brown Jr. tells Wired that there's a possible (if purely coincidental) consolation for missing another deadline -- the airship could be used in a pinch for carrying as much as seven tons of supplies without getting into harm's way, albeit at a fairly glacial 30MPH. The successful first flight won't be much consolation to Mav6, whose Blue Devil 2 was scuttled at the last minute after technical issues; it's nonetheless a relief for US troops, who may get weeks at a time of constant intelligence on enemy movements. Catch a short snippet of the early LEMV journey after the break.

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?

Starting next month, around one thousand frontline personnel in Afghanistan will begin testing the Soldier Body Unit, a sensor kit for recording the effects of explosions on the human body. While that's not the most pleasant of subjects, the blast sensors have been rushed out to collect as much data as possible before soldiers head home in 2014. The US Army's Rapid Equipping Force and the Georgia Tech Research Institute, which developed the sensors, hope to gather info on concussions and traumatic brain injuries to improve aftercare. This will also be used at source to stop super-soldiers heading back out after a concussion and increasing the probability of an even worse injury. Further sensors will be carried on military vehicles, to help measure the effects of IED blasts on passengers. Adding two pounds in extra equipment probably won't make the Soldier Body Unit too popular, but it's thought the kit could weigh in at half a pound once it's been refined.

Smartphones: the future of wartime communication? That is the goal of the US Army through the development of its portable wireless network, dubbed Warfighter Information Network-Tactical or WIN-T. The Army hopes to leverage WIN-T to bring near-instant digital communication to the battlefield by outfitting soldiers with Motorola Atrix handsets running a heavily modified version of Android. An exposé by Wired explains that the system's main goal is information and intelligence sharing; between both soldiers and central command. Friendly troop positions, suspicious vehicles or persons and surveillance video from unmanned areal vehicles (UAVs) can all be mapped and shared with servicemen and women in the field. It's been a dream of the Pentagon since the mid-nineties, but has only recently become monetarily and technologically feasible due to advances in smartphone processing power. It's nerdy, it's fascinating... and this is the stuff the Army is willing to talk about. Hit the source link for the full write-up.

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.

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.

With the modern US soldier turning into a walking gadget, the army has some heavy reasons to lower battery weights. Its own scientists might have the answer, claiming 30 percent energy density jumps could happen using additives they developed. Those "sacrificial agent" materials would bond with electrodes to allow five volts instead of the four they've been stuck on, permitting a "quantum leap" in efficiency and weight. We'll have to see if that'll come to pass, but given the sheer volume of tech that soldiers are strapping on these days, it couldn't be too soon. To see a video of how it works, zap past the break.

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.
