New stealth material could defeat latest radar systems

Stealth aircraft like the F35 fighter generally rely on high-tech absorption materials and unusual geometries to scatter, deflect, and sponge up incoming radar signals. These techniques are exceptionally good at masking a vehicle's shape and size, particularly when swept with side-scanning radar. However, with lower-frequency, directed anti-stealth radar-targeting systems being developed, these surfaces prove much less able to hide an object. To help address this, a team of Chinese scientists has developed a thin electronic material that sheaths an object and effectively absorbs radar signals over a wide range of frequencies.Read More

Robotic sea lion flippers could propel future submersibles

Unlike most other sea creatures, sea lions use their forelimbs instead of a tail for propulsion. They also leave virtually no wake as they travel through the water. With an eye towards applying this design to human technology, George Washington University professor of mechanical and aerospace engineering Megan Leftwich has developed a robotic sea lion flipper.Read More

Taranis drone demonstrates stealth in latest test

Combat pilots aren't going on the dole queue any time soon, but they might want to start dusting off their resumes. BAE Systems Taranis Unmanned Combat Aerial Vehicle has flown for the first time in a full stealth configuration, making it almost invisible to radar ... and bringing the day of the unmanned war plane that much closer to reality.Read More

DARPA commissions a military "stealth motorcycle"

An elite team of commandos zip across rough enemy terrain, on motorcycles that produce no engine noise, yet that also have more range than pure electric bikes ... That's a scenario that DARPA (the Defense Advanced Research Projects Agency) would like to make real. To that end, it recently gave a small business innovation research grant to Logos Technologies, to develop the bikes. Read More

How to build a "stealth" computer display

An additional layer of security (and fun) can be added to your computer's LCD display by following the lead of Brusspup, a well-known online illusionist and computer artist. Just remove your display's outer polarizing filter, and use polarizing sunglasses instead.Read More

Secret Operation 610 – scary mobile art that doubles as a laboratory

Rolling out of a hangar on the former Soesterberg Air Base in Utrecht, The Netherlands, is a black, angular shape that looks like a stealth hermit crab crossed with an airport waiting lounge. This combination of mobile sculpture and laboratory, called Secret Operation 610, was unveiled on September 13 as part of the Festival de Basis. It was built in collaboration by Rietveld Landscape, Studio Frank Havermans, and Koos Schaart over an 18-year period. Read More

Iran unveils homegrown Qaher F-313 "stealth" fighter

Iranian State TV on Saturday showed an unveiling ceremony for what the Iran Defense Ministry claims is a new Iranian designed and built combat aircraft. Defense Minister Ahmad Vahidi said the single-seat Qaher F-313 (Dominant F-313) can operate at low altitudes and was constructed from “advanced materials” that contribute to the aircraft’s “very low radar cross section.” Read More

First-ever dual in-flight refueling of a pair of F-35C fighters

For the first time, a pair of F-35C Joint Strike Fighters have simultaneously refueled from a KC-130 tanker aircraft. The aircraft's afterburners burn an enormous amount of fuel, so an important part of most missions will be refueling before or after combat, or both. This is why the successful dual refueling is an important benchmark for the JSF family. Read More

Avoid snooping UAVs with a Stealth Wear hoodie

Unmanned aerial vehicles (UAVs or "drones") are fast becoming an ever-present eye in the sky, potentially granting governments greater strike and surveillance capabilities than even Orwell’s fictional Big Brother could hope to wield. In response, NYC artist Adam Harvey has created a series of garments which claim to reduce the effectiveness of UAVs. Read More

Taranis stealth drone set to fly this year

It's been 30 months since Taranis, the UK's autonomous stealth drone, featured on the pages of Gizmag when a prototype of the aircraft was unveiled. According to a report in the UK's Telegraph last Sunday, the unmanned combat aircraft is set to undergo flight testing later this year.Read More
