Zephyr, QinetiQ’s solar-powered, high-altitude long-endurance (HALE), Unmanned Air System (UAS) is currently in the air and setting a landmark unmanned flight duration record by demonstrating what is essentially perpetual flight. The official world record for the longest unmanned flight is 30 hours 24 minutes set by Northrop Grumman's RQ-4A Global Hawk in 2001. A previous smaller relative of the current Zephyr holds the unofficial record of 82 hours but this time QinetiQ has FIA officials on hand and has been flying the new 22.5m wingspan plane for the past week, and is closing on the 200 hour mark with another week (168 hours) planned. It needs to land safely to claim the record, but the feat has already demonstrated that the era of low-cost, persistent aerial surveillance has begun. Read More

A prototype of England’s Taranis Unmanned Combat Aircraft System (UCAS) that we first covered back in 2006 has been unveiled for the first time by the UK Ministry of Defence (MoD). Three and a half years in the making and the product of more than a million man-hours the concept demonstrator is designed to test the possibility of developing the first ever autonomous stealthy UCAV that would ultimately be capable of precisely striking targets at long range, even on another continent.

Aimed at the global defense industry, Mercedes unveiled the Light Armored Patrol Vehicle 6.X Concept at the recent Eurosatory 2010 defense industry trade show in Paris, France. Based on Mercedes’ G-Glass the LAPV 6.X boasts greater agility, higher protection and a greater payload capacity than its cousin, the LAPV 5.4. Read More

In these days of PhotoShop and its brethren, it’s becoming almost impossible to tell whether or not an image has been digitally manipulated. While some ‘shopping is done simply for whimsical reasons (see picture above), the matter becomes a bit more serious when things such as military images are altered. Visible watermarks are sometimes overlaid on digital photos, but these permanently alter and obscure that copy of the picture. Recently, however, researchers in India came up with a system for verifying a photo’s authenticity, without altering it in any way. Read More

Land mines are terrifying and indiscriminate weapons, harming soldiers and civilians alike. Even long after the conflict in which they were deployed has ceased they end up killing and injuring civilians and render land impassable and unusable for decades. There are a variety of methods used to detect mines by both humanitarian and military groups, but many are dangerous, most are less than 100 percent reliable and some of the more reliable detection methods are prohibitively expensive. Physicists have now built a relatively inexpensive land mine detection system using off-the-shelf components – including some sourced from online auction sites. Read More

The F-35 Joint Strike Fighter (JSF) program continues to rack up the milestones with the F-35B short takeoff/vertical landing (STOVL) variant breaking the sound barrier for the first time. The F-35B, which completed its first vertical landing in March, hit Mach 1.07 (727 miles per hour) in an off-shore test on June 10 and will be put through a series of supersonic flights that will gradually take the aircraft towards its top speed of Mach 1.6. The F-35B STOVL marks the first time in 100 years of military aviation that a plane has combined radar-evading stealth, VTOL and supersonic speed and may go some way towards justifying the program's other milestone achievement of being the most expensive weapons program in military history.

If you own an Unmanned Aerial Vehicle (UAV), here’s piece of advice: don’t fly it near San Nicholas Island, California, or it could be blasted out of the sky – by a laser. Two such vehicles were successfully shot down there on May 24th by a US Navy laser weapon. According to the official press release, this marks "the first detect-thru-engage laser shoot-down of a threat representative target in an over-the-water, combat representative scenario.” Read More

If a terrorist attack has left an area contaminated with nerve gas, chances are no one wants to add any other noxious substances to it. Using conventional chlorine- and lye-based decontamination agents, however, that’s exactly what’s happening. Not only can these substances run off and harm people or the environment, they can also react with the very materials they’re cleaning up, forming new toxic substances. It is for reasons such as these that the US military has developed Decon Green - a non-toxic set of ultra-strength cleaners. Read More

DARPA has launched an unmanned hypersonic gliding vehicle that can reach speeds up to Mach 20 (13,000mph). The Falcon program aims to develop and demonstrate hypersonic technologies for prompt use in global reach missions and the Falcon Hypersonic Technology Vehicle 2 (HTV-2) forms part of this quest to produce an unmanned, rocket-launched, maneuverable air vehicle that glides through the Earth’s atmosphere at incredibly fast speeds.
