The submarine of the future may come to America in a super fast bubble, traveling under water. Researchers at China's Harbin Institute of Technology developed a new concept for submarine “supercavitation,” where an underwater vessel creates a pocket of air around itself. Inside this bubble, the submarine can travel much faster without friction of water creating drag and slowing it down. Theoretically, a supercavitated vessel using rocket engines could travel inside that air pocket at almost the speed of sound.

The art of the war is complicated, but the science of war is often just a matter of shooting something pain-inducing at the other guy faster and from further away. The Army’s Advanced Hypersonic Weapon program wants to do just that, by creating a missile that moves faster than Mach 5, or almost 3,800 miles per hour. That hypersonic future may be just a little further away than expected. During testing of the weapon in Alaska early Monday morning, the rockets propelling the missile exploded four seconds after liftoff. No one was injured, but the cause of the failure has yet to be determined.

Fortunately for everyone who isn't a fighter pilot, John Kristensen, a Danish Air Force pilot who flew missions in Afghanistan between 2002 and 2003, brought along his GoPro for a flight in an F-16 Fighting Falcon over Greenland. The resulting video is stunning, as he races past icebergs, glaciers, ice floes, snow-covered plains, and fjords. There's a lot that's frozen on the Greenland ice sheet, it turns out. He also flies in formation with other pilots from Fighter Wing Skrydstrup

One hundred years ago, the Panama Canal opened for the first time. A triumph of turn-of-the-century engineering, it connected Pacific and Atlantic, expanding the worlds of maritime commerce and re-writing the sea lanes of the Western Hemisphere.

This camouflage trick is a trait shared by all cephalopods – squids and cuttlefish included -- but now humans are getting in on the color-changing action too.

The heavy, treaded, gun-swinging battlefield behemoths know as tanks haven't changed much since their invention a century ago. Using a crapload of armor, the tank is meant to keep soldiers inside safe from bullets and other projectiles, while shooting a cannon at anything that poses a threat. But the problem with all this armor is that it makes vehicles slow and therefore more vulnerable. DARPA wants to change that. Their new Ground X-Vehicle Technology (GXV-T) initiative aims to get vehicles beyond armor, figuring out new ways to keep the people inside safe without sacrificing mobility.

Powered by a pusher propeller, covered in pixel camouflage, and furnished with stadium-seating for its two crew members, the Advanced High Performance Reconnaissance and Surveillance Aircraft (AHRLAC) looks like an alternate history version of a World War I fighter. The result of a collaboration between South Africa's Aerosud aviation firm and the Paramount Group, the AHRLAC is designed as a cheap alternative to the big name in military surveillance right now: drones.
