Navy drone swims like a shark to spy on foes
It's hard to covertly gather intelligence on the open seas; conventional drones and submarines make it rather obvious that something's up. The US Navy might just have a stealthier option with its experimental GhostSwimmer drone, which recently finished tests. The five-foot-long robot looks and swims much like a shark, letting it spy on enemies (or inspect friendly ships) without being conspicuous -- as long as curious foes don't get too close, anyway. It goes as deep as 300 feet, and it can operate autonomously for long enough that the Navy doesn't have to stay nearby to keep watch.

US Navy puts its first laser weapon into service
It's official: the US Navy has entered the future. Vice Admiral John Miller tells Bloomberg that the USS Ponce, an amphibious transport, has been using the Navy's Laser Weapon System (LaWS) in the Persian Gulf since late August. The high-tech arsenal is no threat to larger vessels, but it's potentially ideal for defending against Iran's fleet of smaller ships. The Ponce can use non-lethal laser flashes to spook enemies or thwart their sensors, and it can destroy small craft (including airborne drones) if they don't heed warnings. It'll take some time before laser weapons are a common sight on the high seas, since the Navy wants to know how it fares in real-world conditions; dust, heat and other Gulf conditions could lead to failures. If it pans out, however, there's a real chance that the days of conventional small deck guns are numbered. [Image credit: John F. Williams/US Navy, Flickr]

Doctors report a case of Google Glass addiction
You've probably heard of Google Glass owners who seemingly can't put the wearable down, but there's now at least one reported instance of genuinely addictive behavior. Doctors at Naval Medical Center San Diego claim that a 31-year-old Navy serviceman is the first person to be diagnosed with a Glass-related internet addiction disorder. The patient wore the head-mounted computer for up to 18 hours a day, and was so attached to it that he would instinctively reach for his right temple (to activate Glass) whenever you asked him a question, whether or not the device was there. He's getting better after having spent 35 days in on-site treatment, according to doctors; that reflexive movement doesn't come up so often, and the man is both less irritable and more focused.

The Big Picture: NASA's Orion capsule floats inside US Navy ship
It might take some time before space taxis become the real deal. Yet, that doesn't take away from the fact they're extraordinarily amazing in their current stage. One of the most well-known programs is, of course, NASA's Orion capsule, which has been in development for a few years now. Obviously, putting Orion through its paces is key for the space administration. So, what you see above is a test model of the spacecraft while it floats inside the USS Anchorage, a US Navy ship. Reuters snapped the image after Orion was found during a recovery test near the Californian coast, as NASA prepares by simulating different scenarios ahead of the capsule's first official unmanned launch.

Watch the US Navy's swarm of robotic boats take to the sea
Overwhelming numbers can help win a sea battle, but sailors are far too valuable to simply throw away -- and the US Navy knows it. To that end, it recently tested a swarm of robotic gunboats that work in tandem to either protect a main warship or surround the enemy. As you can see in the video below, they're very well coordinated. The vehicles' Control Architecture for Robotic Agent Command and Sensing (CARACaS) lets them both operate independently while sharing their paths and radar data with each other, keeping them both out of each others' way and aware of any potential threats.

Octopus-like camouflage can hide you in plain sight
Octopuses and other cephalopods are masters of disguise -- their prey often doesn't realize the danger until it's too late. It only makes sense to model active camouflage after that behavior, then, and a team at the University of Illinois has managed just that. Their octopus-like material uses layers of photosensors, actuators and temperature-sensitive pigment to detect ambient light and change colors in response. Individual points on the unversity's test skin can turn from black to transparent within a second or two, letting it quickly blend into its surroundings -- or purposefully stand out, as you see above. The technology will ideally allow for many colors in the future, although that's not an immediate priority.

Lockheed Martin's FORTIS exoskeleton helps US Navy with heavy lifting
While it may not be a full suit of high-tech gadgetry like Iron Man dons, the US Navy is set to test exoskeletons from Lockheed Martin. In the first contract to employs the company's strength-boosting garb for industrial use, two FORTIS exoskeletons will help carry heavy loads for the trial period. The lightweight unpowered option lends endurance by using the ground to help bear the mass. During the testing phase, the company hopes to further develop the tech for use at Navy shipyards where a smattering of heavy tools are needed for maintenance. "By wearing the FORTIS exoskeleton, operators can hold the weight of those heavy tools for extended periods of time with reduced fatigue," said Adam Mill, director of new initiatives at Lockheed Martin Missiles and Fire Control.

Navy sailor pleads guilty to hacking from an aircraft carrier
You may think that the US Navy's biggest digital threats come from the outside, but that's not always the case. Former Navy serviceman (and leader of the hacking group Team Digi7al) Nicholas Paul Knight has pleaded guilty to charges that he and co-defendant Daniel Kreuger conspired to steal identities from numerous internet sites, including a Navy personnel relocation system. Knight was caught after investigators realized that someone in Digi7al was posting on Twitter from the Navy's internal network -- as it turns out, the sailor was breaking into databases while he was a system administrator aboard the aircraft carrier USS Harry S. Truman.

US Navy's Triton UAV completes initial flight testing
One of Northrop Grumman's new war/spy gadgets, the Triton unmanned aerial vehicle, just got closer to joining the US Navy's reconnaissance fleet. After almost two years since the defense tech company announced the aircraft, the Triton has finally completed its initial test flight program and has now been cleared to fly at various altitudes, speeds and weights. The tests, which kicked off in May 2013, spanned 13 flights (including long-endurance ones) with a total of 81 hours flown at altitudes up to 59,950 feet. To put that in perspective, commercial airplanes usually fly at around 35,000 feet in the air. While the company and the Navy successfully got through this phase, they still have to tackle more tests before the Triton goes into service sometime in 2017. They're currently preparing to equip two Tritons with sensor systems designed to take high-res images, detect targets with radar and provide a means of communication between military units over long distances. These UAVs will take to the air this June or July to determine whether the sensors work as intended. In the future, the Navy plans to build 68 Tritons specifically to work with manned P-8 Poseidon patrol planes. If the latter sounds familiar, it's because a deployed P-8 unit is currently involved in the search for the missing Malaysian Airlines flight MH370. When the Triton's ready for primetime, it could considerably extend the P-8's search range, making it better equipped to handle similar missions.

US Navy's X-47B unmanned jet successfully lands on an aircraft carrier
The US Navy's unmanned plane, the X-47B, has been in development for years. It first flew in 2011, began testing aboard an aircraft carrier in late 2012, and finally took off from a floating airstrip earlier this year. Taking off from a moving ship is easier than landing on one, of course, but the X-47B accomplished that task today when it successfully landed on the USS George H.W. Bush. And, just to show off, shortly thereafter the X-47B was launched from carrier via catapult and, once again, landed successfully. So, it looks to be only a matter of time before our Top Guns look more like Watson, and less like Tom Cruise.

US Navy's X-47B is the first unmanned plane launched from an aircraft carrier (video)
After limbering up with taxi tests since December, the X-47B unmanned combat air system has finally taken off from an aircraft carrier, making it the first pilotless plane to have successfully done so, and with a catapult launch to boot. Despite the craft's ability to fly on its own, it was controlled by a human aboard the George H.W. Bush after it was flung from the ship. Once in the air, the Northrop Grumman-built craft was guided back for a landing on a runway planted on terra firm. Now that the bird's proved it can handle launches at sea, other excursions will put the automatic navigation and landing features through their paces. Hit the break for a video of the X-47B taking to the skies.

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.

SAIC shows how DARPA's submarine-tracking drone ship finds its silent targets (video)
Some of us have been feeding advice to DARPA's ACTUV sub-tracking drone project for more than a year, but we haven't had a in-depth look at how the autonomous ship will go about its business, especially when chasing very silent diesel-electric subs. Thankfully, craft designer SAIC has stepped in with a detailed video tour. If there's suspicions that a diesel sub is in the area, the US Navy can deploy sonar buoys that give the ACTUV an inkling of where to go first. After that, the drone takes over with both long-range and short-range sonar. The vehicle can gauge the intent of ships in its path (with human failsafes) and hound a target for up to 13 weeks -- either letting the Navy close in for an attack or, ideally, spooking the sub into avoiding conflict in the first place. While ACTUV won't hit the waves for years, there's a promise that we'll always know about underwater threats and deal with them on our own terms.
Jon Fingas12.27.2012X-47B unmanned combat aircraft starts light workouts aboard USS Truman (video)
While the USAF has been tacking missiles onto Predator drones for quite some time, so far a true unmanned attack plane has yet to grace any carrier decks -- until now. The US Navy has started flogging an X-47B Unmanned Combat Aircraft System (UCAS) aboard the USS Truman, with a video (below the break) showing it taxiing around the flight deck. The current round of tests has focused on "handling and control characteristics," but officials have said the robotic stealth fighters could be launched from the ship's catapult "if all conditions are nominal." The X-47B has already completed some flight tests, and was even launched from a sling on November 29th, but all that happened at naval air bases, not on the open water. With all the unmanned aircraft coming into the military's system, we can imagine a lot of pilots on the Truman were giving it the stink-eye.

US Navy tests first 11-meter missile-firing sea drone (video)
Advances in unmanned military tools and vehicles have come on leaps and bounds, but, until now, we haven't seen a weapon firing drone operating in the seas. A recent test taking part offshore near Maryland saw several missiles launched from a new remote-controlled inflatable-hulled ship. While the Navy has used drones before for mine clearing and other defensive tasks, the small boat (similar to that pictured above) is the first experiment to involve true offensive capabilities. The almost zodiac-like craft has been an ongoing project over recent years, and contains a fully automated system which the Navy calls a "Precision Engagement Module" which uses an Mk-49 mounting with a dual missile launcher manufactured by Rafael. The hope is that such vehicles could patrol the coastline, or serve as a first defense against pirates, and other such small, fast-moving seafaring dangers. If you want to catch it in action, head past the break for the video, but don't be fooled. While it might look like a series of misses, the Navy claims this is just a trick of the camera angle, with all six missiles apparently making contact.

US Navy deploys SeaFox submarines to Persian Gulf for universal mine control
Tasked with mine detection and eradication in the Persian Gulf, the US Navy has sent a fleet of unmanned submarines to help keep the Strait of Hormuz open in Iran. Dubbed the SeaFox, each vehicle houses an underwater TV camera, sonar and a dose of explosives. Tipping the scales at less than 100 pounds, the subs are about four feet in length and are controlled via fiber optic cable that sends the live feed back to the captain of each ship. SeaFoxes can dive to depths of 300 meters and boasts a top speed of six knots. The units are thrust into action from helicopters, small rubber boats and off the rear of minesweepers and are capable of disposing of the aforementioned weapons of both the floating and drifting sort. There is one small catch: the $100,000 submarine destroys itself in the process, making each successful trek a suicide mission of sorts.

Lockheed Martin F-35 Lightning II stealth fighter cockpit demonstrator hands-on (video)
We spend hundreds of hours on board a variety of airplanes each year, most often en-route to a trade show or product launch event, but occasionally we have a rare opportunity to hop on board military aircraft, to test out unrelated products, or, even more unusually, to take a seat behind the yoke. Sadly that's not what we're doing today -- well, not exactly. We are taking a closer look at the F-35 fighter jet at Lockheed Martin's Fighter Demonstration Center just outside our nation's capital, but, being in the middle of a corporate complex, there's no actual Lightning II on hand. We were able to take a simulated ride, however -- this isn't your ordinary 4D sickness-inducing amusement park thrill. The F-35 is by far the most advanced Lockheed jet to date, with updated radar, all-internal weapons, improved tracking systems, 360-degree infrared coverage with a visor readout, and a full-stealth design, not to mention the incredibly capable glass cockpit powered by more than 9.3 million lines of software code, and an overall smoother experience for pilots that could end up spending shifts of 12 hours or longer in flight. The F-35 has already seen plenty of field time in the US, with more than 500 flights already in 2012, and it's set to make its way to the UK armed forces next week and the Netherlands later this year, but while the aircraft is quite familiar to the pilots tasked with flying it, the public hasn't had an opportunity to experience Lockheed's latest airborne warrior. We flew a simulated mission within a grounded duplicate of the flyable F-35 cockpit, and the capabilities and improvements are quite clear -- you definitely don't want to encounter an F-35 from a previous-generation aircraft. The dual 8 x 10-inch touch-enabled displays combine to give you 8 x 20 inches of real estate, with dedicated modules for the weapons systems, targeting, and navigation easily accessible -- you can also move them to different panels depending on your current objective. A pair of joysticks at the left and right side provide direct access, letting you move a cursor to track enemy crafts or ground-based targets as well, and a very slick heads-up-display mounted in the helmet provides infrared mapping and instrument readouts. Overall, it seems to be an incredibly powerful system. Unfortunately, the mock-up on display here isn't accessible to the public, but you can join us for a behind-the-scenes look just after the break.%Gallery-160208%

Attack of the drones: US Navy picks Linux for its unmanned VTOL aircraft control system
Disagreement between passionate Windows and Mac OS diehards have caused many a kerfuffle on the Interwebs. When it comes to the tactical control system of the US Navy's autonomous vertical take-off-and-landing craft, however, the military branch is putting its money on a different operating system. The Navy just awarded a contract worth nearly $28 million to Raytheon Intelligence and Information Systems to transition its VTOL drones to using its own flavor of good, old Linux. Eventually, the Navy plans to have 168 Northrop Grumman MQ-8B Navy Fire Scout drones rocking the OS as part of its fleet. The Register reports that the move was likely made for security reasons following a malware attack on the Air Force's Windows-based drone system last year. Add Samsung's recent inclusion into the Platinum ranks of Linux's core supporters and you really can't blame fans of the operating system if they decide to wear shades while pondering its future.

Navy plans ship-based LTE for close-quarters communication
Bandwidth is a precious commodity on military vessels. Ships in the US Navy fleet are generating more data, but the pipe it's getting pumped through isn't getting any larger. What's more, with limited connectivity options on the table, the sea-faring military wing is missing out on all the smartphone and app store fun. Rather than turn green with envy, or turning their dress whites is for camouflage cargo pants, the Navy is beefing up its mobile tech arsenal, beginning with the U.S.S. Kearsarge, U.S.S. San Antonio and U.S.S. Whidbey Island. The ships will serve as test beds for a nautical LTE system, with a range of about 25 miles. The 4G network will serve as a localized platform for wirelessly feeding data to sailors, as well as a way for the enlisted to connect to the outside world. On the backend, the Marines are working on a new satellite broadband service that should be able to provide ships with 300 megabits of shared bandwidth. Satellite internet and off-grid LTE might induce yawns in some, but they're certainly a major part of modernizing our fighting forces. For more info, check out the source link.

Navy looks into UV cloak for stealth aircraft
The Navy's invested good money in the F-35 Joint Strike Fighter, which obscures radar waves and redirects engine heat to evade recognition by infrared sensors. But that stealth flier is still vulnerable to another type of detection: UV sensors. The Pentagon recently began soliciting proposals to develop a device that cloaks aircraft from ultra-violet detection systems. The hope is that such a technology could shield aircraft from missile seekers that scan the sky for telltale "UV silhouettes." According to the call for research, the solution could involve a device that disperses a cloud of quantum dots or other materials to veil jet fighters in a shapeless mass of UV shadow. Given that this is a rather daunting task, it's not surprising that the development timeframe and projected cost are still up in the air.
