American Chemical Society, September 5, 2012: Borrowing a technology used to improve the effectiveness of drugs, scientists are reporting discovery of a new explosive more powerful than the current state-of-the-art explosive used by the military, and just as safe for personnel to handle. Their report appears in ACS’ journal Crystal Growth & Design. Adam J. Matzger and colleagues explain that a technique for engineering medicines and other materials, termed cocrystallization, is attracting attention as a way to make improved explosives, rocket propellants and fireworks - Powerful new explosive could replace today’s state-of-the-art military explosive

DARPA, September 10, 2012: Today, DARPA’s Legged Squad Support System (LS3) program demonstrated two robotic “pack mule” prototypes for the Commandant of the Marine Corps, Gen. James F. Amos, and DARPA Director, Arati Prabhakar. The first platform underwent its initial outdoor test earlier this year and has matured through continual testing and improvements to the point that two functioning platforms have started to run through the paces similar to what they could one day experience carrying gear for a squad of Marines or Soldiers. The goal of the LS3 program is to demonstrate that a legged robot can unburden dismounted squad members by carrying their gear, autonomously following them through rugged terrain, and interpreting verbal and visual commands. “We’ve refined the LS3 platform and have begun field testing against requirements of the Marine Corps,” said Army Lt. Col. Joe Hitt, DARPA program manager. “The vision for LS3 is to combine the capabilities of a pack mule with the intelligence of a trained animal” - DARPA’s Four-Legged Robots Walk Out For Capabilities Demonstration

Defense Tech, September 19, 2012: Textron Defense Systems has a new flying drone that’s designed to explode on contact with enemy positions. The compact BattleHawk Squad Level Loitering Munition is armed with a 40mm high-fragmentation charge. It has a video camera built into its nose, so ground troops can remotely pilot it over rooftops or hills to attack hiding enemy forces. The BattleHawk weighs about five pounds when it’s packed inside its special launching tube. A spring propels the drone into the air and the electric motor starts up the tiny, rear propeller. “Once it’s launched, it’s armed,” Mick Guthals, director of Business Strategy & Capture at Textron, said while displaying the BattleHawk at the Air Force Association’s annual conference in Washington, D.C. Sept. 17–19 - Textron’s Remote-Controlled Flying Bomb

Boeing, October 22, 2012: A recent weapons flight test in the Utah desert may change future warfare after the missile successfully defeated electronic targets with little to no collateral damage. Boeing [NYSE: BA] and the U.S. Air Force Research Laboratory (AFRL) Directed Energy Directorate, Kirtland Air Force Base, N.M., successfully tested the Counter-electronics High-powered Microwave Advanced Missile Project (CHAMP) during a flight over the Utah Test and Training Range that was monitored from Hill Air Force Base. CHAMP, which renders electronic targets useless, is a non-kinetic alternative to traditional explosive weapons that use the energy of motion to defeat a target. During the test, the CHAMP missile navigated a pre-programmed flight plan and emitted bursts of high-powered energy, effectively knocking out the target's data and electronic subsystems. CHAMP allows for selective high-frequency radio wave strikes against numerous targets during a single mission. "This technology marks a new era in modern-day warfare," said Keith Coleman, CHAMP program manager for Boeing Phantom Works. "In the near future, this technology may be used to render an enemy’s electronic and data systems useless even before the first troops or aircraft arrive" - Boeing Non-kinetic Missile Records 1st Operational Test Flight

Rheinmetall, December 18, 2012: Rheinmetall has successfully tested its new 50kW high-energy weapon technology demonstrator. [...] ...a massive, 15mm-thick steel girder was cut through at a distance of 1,000 metres. The successful shooting down of several nose-diving target drones at a range of two kilometres formed the second major highlight. [...] The third highlight: detection, pursuit and successful engagement of an extremely small ballistic target. A steel ball measuring 82 mm in diameter and travelling at approximately 50 m/sec, the target replicated a mortar round - Flying colours: Rheinmetall successfully tests 50kW high-energy laser weapon

Aviation Week, May 2, 2013: The U.S. Air Force Research Laboratory’s (AFRL) Boeing X-51A Waverider demonstrator successfully achieved sustained, scramjet-powered, air-breathing hypersonic flight above Mach 5 in its final test flight on May 1. Although the Air Force is not yet commenting on details of the flight, the X-51A is thought to have experienced positive acceleration to speeds in excess of Mach 5 and run for the full duration of the planned powered phase of the test. Based on targets established for the previous test attempt, this could have been as long as 300 sec., followed by an unpowered gliding descent of around 500 sec. prior to impacting the sea in the Pacific Test range west of California. If these times and speeds are confirmed, they will represent new records for sustained, air-breathing hypersonic flight - X-51A Waverider Achieves Hypersonic Goal On Final Flight

A Guide To Spotting And Hiding From Drones

Consider it a rough Audubon guide to the mechanical fauna of battlefields. Created by Amsterdam-based designer Ruben Pater, the Drone Survival Guide is, on one side, a rough bird watcher's guide to the modern robot at war. The other side is a short section of printed survival tips, and the guides are available in Pashto, Dutch, German, Italian, Indonesian, Arabic, and English.

The selection of drones included in the guide leads heavily towards those from NATO member countries, with the United Kingdom, Canada, France, Germany, and the United States all represented, as well as NATO itself, for the other member countries that use these drones. Partly because those are the countries that have used drones, in Afghanistan and elsewhere, the most, but partly because they are just the countries where it is easier to get information about the scale and wingspan of their flying robots.

Also represented are drones from China, Morocco, India, the United Arab Emirates, and Israel. In fact, Pater told Popular Science that part of his inspiration came from people in the Gaza Strip, who filmed Israeli drones overhead, and the challenge of making out what kind of machine it is from the silhouette alone. The silhouettes also resemble Airplane Spotter Cards, made during World War II so that servicemen could differentiate between aircraft, both friendly and allied.

The drones vary vastly in scale, from the 130-foot wingspan of the Global Hawk to the 23-inch width of the Parrot AR quadcopter. They're all divided into two categories, based on function: those that spy, and those that both spy and kill. The other distinctions, between military and domestic surveillance, are less solid. Pater gave an example of how something like the Scan Eagle complicates that. It's a military drone, used for years by NATO forces fighting abroad, but when police in Pater's Holland ("like one of the safest places on earth," he told Popular Science) obtained them, they started using them to track down drug dealers and illegal marijuana growers. The drone, after all, is a tool that is used by people. How it is used depends on the people themselves.

There's also the limited nature of a single-sheet survival guide. Pater concedes that it's mostly art. Several of the tips for survival come directly from an al Qaeda guide to countering drones, published by the Associated Press in January 2013. Included in these tips are "To hide under thick trees because they are the best cover against the planes," (note the hiding figure in the image) and "Spreading the reflective pieces of glass on a car or on the roof of the building," which Pater's guide mirrors by both being printed on reflective material and advocating space blankets (which also hide heat from infrared cameras) as a way to hide.

As a tool for survival, it might be limited, though no less so than other artist attempts at drone-proofing the world. As a work of design, and a rough guide for drone spotters, it's excellent. Pater hopes to see the guide in the hands of activists, and given the many languages it's been translated into, it could easily have an educational role in the right hands.

The drone guide, complete with survival tips, can be ordered from his site.

Texas Students Hijack a U.S. Government Drone in Midair

The U.S. government, understandably, doesn't want its drone technology to fall out of the sky and into other peoples' laps. But being able to hijack a drone and control it? That's even worse. And a team of researchers has done it for 1,000 bucks.

The University of Texas at Austin team successfully nabbed the drone on a dare from the Department of Homeland Security. They managed to do it through spoofing, a technique where a signal from hackers pretends to be the same as one sent to the drone's GPS.

We've seen spoofing before; it was reportedly used to bring down the drone that crashed in Iran last year. As the researchers point out, we'll be seeing (or maybe not seeing) more and more drones in the skies as the technology becomes more widely used, so making this technique ineffective will be high on Homeland Security's priority list.
