Defense contractor Raytheon is on a roll lately. First the company demos that powerful laser cannon we showed you earlier, and now Raytheon is showing off a monocle-like helmet attachment that'll have pilots killing with a glance.

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.

Not too long ago DARPA put out a call for a flying car, wanting something that had all the versatility on land as a Humvee, but also had Vertical Takeoff and Landing (VTOL) capabilities. Texas-based AVX Aircraft is stepping up to the plate, and its concept looks pretty close.

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).
