Navy enlists UAVs to uncover atmospheric ducts, protect comms
Turbulence. A minor bother for us, but a huge issue for enlisted seamen. So-called "ducts" in the lower atmosphere can wreak all sorts of maritime havoc; trapping radar and causing radio comms to travel further than expected and into the hands of the enemy. The Office of Naval Research's Ocean Battlespace Sensing Department (rad name, right?) isn't satisfied with using balloons to keep track of the ducts anymore, and is deploying drones instead, including Insitu's ScanEagle shown above. The result should be a greater understanding of how atmospheric conditions affect radar and communications, which could ultimately provide a tactical advantage -- at least while we wait on those 100-kilowatt lasers.

Navy awards weaponized railgun manufacturing contract to BAE Systems
Just over 18 months after making its video debut, the Navy's electromagnetic railgun has a manufacturer. BAE Systems -- known for e-ink-powered tank camouflage, autonomous spiderbots and machine-gun-mounted lasers -- won the government contract and hopes to have phase-two prototypes ready "as early as next year." While the current design is capable of firing one shot, the Office of Navy Research hopes for six to ten shots per minute. If that doesn't scare you, consider this: The pulse-driven projectiles travel at Mach 6 and can hit targets over 100 nautical miles away. Don't worry, it's not too late to rethink that career of sailing the high seas as a pirate and get to work on that accounting degree instead.

Giant robot jellyfish reporting for recon duty, sir (video)
As if there weren't enough real jellyfish around to trigger our thalassophobia, researchers at Virginia Tech have created Cryo -- an eight-armed autonomous robot that mimics jelly movement with the help of a flexible silicone hat. The man-sized jellybot altogether dwarfs previous efforts, hence the upgrade from small tank to swimming pool for mock field tests. And unlike the passively propelled bots we've seen recently, Cryo runs on batteries, with the researchers hoping to better replicate the energy-efficient nature of jelly movement to eventually increase Cryo's charge cycle to months instead of hours. That's also the reason these robotic jellyfish are getting bigger -- because the larger they are, the further they can go. Potential uses include ocean monitoring and perhaps clearing oil spills, but the US Navy, which is funding the work, sees an opportunity to recruit jellies for underwater surveillance -- a job the researchers say is suited to their natural-looking disguise. But, before the tables are turned, you can spy on Cryo for yourself in the video below.
