FedEx CEO Fred Smith sees unmanned drones as useful for more than just recon and tactical strikes. Someday soon, robotic aircraft could deliver packages all over the world, and, thanks to some new military tech, take off from airports just like passenger planes.

We’re all familiar with tasers and pepper spray. Now, there’s a new non-lethal option to get acquainted with: the “Dazer Laser.” It won’t leave criminals blind forever, but it will have them seeing green for the few seconds it takes police officers to go in for the tackle.

Finally, we are living in a world where gigantic lasers can shoot down planes. It’s been a sci-fi dream for ages, but now, Raytheon has a functioning anti-aircraft laser that can actually take planes out of the sky.

Having a plane that can fly continuously without refueling has long been a dream of military planners, but that dream might soon become reality if the QinetiQ Zephyr solar plane lives up to its billing.

Did you know that to communicate effectively, submarines have to rise up to periscope depth? The dangers are obvious, but moreover it’s just surprising that in this day and age a better solution doesn’t exist. Lockheed Martin reckons its got the answer with a new buoy.

Everybody is familiar with the unmanned Predator drone aircraft the US military has been using in Afghanistan, but now there are plans to replace ground support troops with a fancy upgraded golf cart called GUSS (Ground Unmanned Support Surrogate).

It seems like airships are the new hot vehicles for the U.S. military . Amazingly efficient, they’re able to stay in the air at lower altitudes for longer than any traditional plane, making them perfect for specialized missions that require long periods of aerial observation.

Improvised Explosive Devices, or IEDs, are a huge problem in Iraq and Afghanistan. How should the military take care of them without damaging any people or equipment? The new strategy: microwaves.

The Big Bad Wolf had to huff and puff to blow away the Three Little Pigs’ houses, and even then he was foiled by the pig who used bricks. If he wanted to do the job properly he should have built a vortex cannon.

Satellite cameras can already read license plates, but soon they’ll be able to count the hairs on your head. That’s thanks to the scientists at Rensselaer Polytechnic Institute, who’ve figured out a way to enhance infrared imaging with a series of holes that are each just 1.6 millionths of a meter wide. Nestled inside each one of those nano-sized holes are quantum dots, ultra-tiny crystals packing some super-powerful optical and semiconductor magic. This bit of microscopic trickery creates images and night vision that’s 20 times sharper than the best systems we have now. We already know about
