Military's Self-Flying Helicopter Gets Modded to Fight Wildfires

2014-11-18 21:20:01| Industrial Machines - Topix.net

Fighting a wildfire requires a lot of manpower and a lot of equipment, including helicopters and airplanes for aerial support. The problem with the humans in those aircraft, however, is not only that do they put their lives at risk - and sometimes lose them - they're not actually very efficient.

US militarys experimental hypersonic weapon explodes seconds after launch

2014-08-26 17:01:47| Extremetech

It must be the season for exploding rockets: The US Army's experimental Advanced Hypersonic Weapon, which will eventually be able to bomb anywhere in the world within an hour, exploded just four seconds after launch in Alaska. Similar to last week's self-detonating SpaceX rocket, the US Department of Defense detected an error within the system shortly after launch, and thus decided to detonate the entire thing rather than risk any extra collateral damage. No one was injured by the incident, though falling debris did damage the rocket's Kodiak Launch Complex.

US militarys air optical fiber increases the power of laser weapons, networks, science

2014-07-24 16:43:04| Extremetech

Researchers in the US, funded by the US military and the National Science Foundation, have managed to turn air into an "optical fiber." This breakthrough allows the scientists to turn thin air into an optical waveguide, allowing for much better transmission of lasers through free space -- much in the same way that glass and plastic waveguides allow for efficient transmission of laser light over long stretches of optical fiber. As you might have guessed from the US military's involvement, this could be big news for laser weapons -- but there are repercussions for laser-based communications and scientific research as well.

US militarys mysterious X-37B space plane passes 500 days in orbit, but we still have no clue what its actually doing up there

2014-04-28 15:12:03| Extremetech

For just over 500 days, the US Air Force's mysterious X-37B OTV-3 robotic space plane has been casually orbiting the Earth. What's truly weird, though, is that its payload, current mission, and combat capabilities are completely unknown. X-37B OTV-3, one of the world's largest artificial satellites, has been up there for 500 days, shows no sign of coming down any time soon, and we have no idea what it's doing or what it can do.
