Wind turbines can be a radar operator's worst nightmare. By scrambling radar waves as blades spin faster or slower, large wind farms are sometimes capable of erasing airplanes from radar screens completely. But a Danish wind turbine company and a UK defense contractor may have found a solution by unveiling the first "stealth" wind-turbine blade last month.

Google's Android operating system for cell phones could allow soldiers to track fellow squad members and even unmanned drones in real time on a map -- as long as the humans and robots are on their buddy list.

Blimps first soared above battlefields in 1794 to spy on Austrian and Dutch troops. Now the U.S. Army wants them as radar platforms for defense against cruise missiles. A Raytheon-designed blimp made its first flight yesterday at Elizabeth City, North Carolina.

Have you ever been taking pictures of an entire country from space and thought, "you know what, this is ok, but I want to photograph the entire hemisphere at once,"? Well, with Raytheon's new 16-megapixel infrared sensor, you can.

Or, more precisely, the government can. Designed to work as part of a satellite, the sensor uses 4,096 pixel rows and columns to produce what the company calls, "an 'unblinking eye' over an entire hemisphere."

Here at Popular Science, we work under the assumption that ray guns are cool. But you know what's even cooler? A flying ray gun. And thanks to an $8 million dollar funding bump from the Air Force, a flying ray gun is closer to production than ever.

The defense company Raytheon unveiled the beam weapon in 2001; back then they mounted the device on a Humvee. Now, the military's Joint Non-Lethal Weapons Directorate has requested an upgrade to the weapon that would allow the JNLWD to attach it to helicopters and other aircraft.

Iron Man's fictional tech may soon become real. Inside a mountain lab, researchers have already built motorized suits that give ordinary people superhuman strength.

We've told you all about the Raytheon Sarcos XOS exoskeleton, the smart suit of armor that endows its wearer with super-human strength. Now see it in action, and meet the minds behind both Iron Men—real, and imaginary.

Afghanistan. A hidden bunker. Four men with rifles guard a thick, rusted steel door. Bam! A huge fist pounds against it—from inside. Bam! More blows dent the steel. The hinges strain. The guards cower, inching backward. Whatever's trying to break out is big. And angry.

Since the bombing of the U.S.S. Cole in 2000, protecting docked ships-both military and commercial-has been a big priority in the fight against terrorism. The Department of Homeland Security has already awarded $489 million to help guard the nation´s ports, spurring a number of innovative ideas, the latest of which is an underwater system that blasts enemy swimmers with painful acoustic waves. Patented by the Raytheon Corporation last October, the system is the brainchild of former Navy and Raytheon acoustics expert Frederick Di Napoli. His scheme is simple: Generate a region of high-pressure, low-frequency sound around the ship, creating a sort of sonic fence that â€shocks†anything that swims through it. Although a diver would probably flee from pain, Di Napoli says, "you could really dial up the pressure and make it lethal if you had to."
