The game that makes drone warfare personal

Killbox is a game that creates humans out of brightly colored 3D shapes, only to slaughter them in the most dehumanizing way: a drone strike. And not just any drone strike -- the game is based on the first real-life UAV mission ever carried out in an...

DARPA outs unmanned drone-launching sub, piracy suddenly less attractive

DNP DARPA

UAVs and UUVs may be unmanned, but they still need a ride to the mission area. Cue the Hydra: an undersea troop-carrier that transports drones. Unlike a submarine, this submersible can operate in shallow waters and charge the batteries of its pilot-free payloads as well as transmit collected data. Even more impressive, it can launch its flight-worthy passengers without surfacing. If this sort of thing turns your crank, head over to John's Hopkins University next month to catch a presentation from DARPA. If your security clearance is high enough, you can even snag a special classified meeting after the regular Joes leave.

DARPA threat detection technology uses a camera to see targets, software and soldier brains to identify them

DARPA threat detection technology uses a camera to see targets, software and soldier brains to identify them

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.

Military hunting smartphone safety to hold off enemy bugs, spooks

military-smartphone-safety-malware-protection

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.

Navy looks into UV cloak for stealth aircraft

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.
