Navy enlists UAVs to uncover atmospheric ducts, protect comms

DNP  Navy enlists UAVs to battle atmospheric ducts that wreak havoc on radar and radio

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.

Night vs. Day Aircraft Carrier Landings in One Harrowing Video

YouTube user Carl Vause recently uploaded a side-by-side shot of two identical aircraft carrier landings—one during the light of day and one in pitch black. The result is absolutely stunning.

What Happens When the US Navy Does a Donut in the Pacific Ocean

And you thought your Hyundai had moves. This is the littoral combat ship USS Independence showing off its turning radius last week. Technically it’s a display of maneuvering prowess, but you can’t help but think it was also a chance for a bunch of able-bodied seamen to say wheeeeeeeeeeeeeeee.

The Navy Accidentally Bombed The Great Barrier Reef . . . Sort Of

The Navy Accidentally Bombed The Great Barrier Reef . . . Sort Of

Okay so this whole thing isn’t ideal, but it’s also not as bad as it sounds. Basically on Tuesday there were two Navy AV-8B Harrier fighter jets that had launched from the USS Bonhomme Richard aircraft carrier and were doing a training exercise. They planned to drop bombs on Townshend Island bombing range, but were told by controllers that the area wasn’t clear. The problem was that they didn’t have enough fuel to land with such heavy loads. So they, you know, unloaded. Right onto the Barrier Reef.

What the Navy Shoots for Target Practice

What the Navy Shoots for Target Practice

Practice makes perfect. That includes the ability to accurately fire some of the biggest, baddest, and deadliest weapons systems in the US Navy. But since the indiscriminate shelling of passing ships is generally frowned upon by the maritime community, here’s what US sailors take aim at instead.

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.

The X-47B Drone Has Landed on a Carrier, And War May Never Be the Same

It’s not often that we get to witness aviation history being made, but when we do, it’s often awesome. Such is the case with the U.S. Navy’s X-47B which just became the first unmanned aircraft to land on an aircraft carrier.

Northrop Grumman’s MQ-4C Triton long-range drone completes first flight (video)

DNP  Northrop Grumman's MQ4C Triton longrange drone completes first flight

Northrop Grumman’s MQ-4C Triton unmanned aircraft is one step closer to serving the Navy in reconnaissance and surveillance missions, having just completed its first flight. The drone spent 80 minutes in the air, reaching an altitude of 20,000 feet. That’s child’s play compared to the aircraft’s full potential: according to the Navy, it can soar at up to 60,000 feet and stay airborne for as long as 30 hours, due in no small part to its 130-foot wingspan. By 2015, the Triton will undergo operational testing and evaluation, and the Navy hopes to add additional aircraft to its existing fleet (currently just two strong). Check out the long-range spy plane in action just past the break.

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.
