x-47b

The U.S. Navy's X-47B is one step closer to being ready to start making test flights off of aircraft carriers after completing its first-ever arrested landing.

According to the Navy, the X-47B, also known as the Unmanned Combat Air System (UCAS), successfully grabbed hold of a special arrester cable with its tailhook, quickly stopping the aircraft during the May 4 test. That marked an important milestone in the development of the UCAS program.

The jet-powered X-47B is a prototype meant to fly autonomously, unlike many drones such as the Predator, which are usually flown remotely by ground-station-based pilots. … Read more

We now know that the pilotless X-47B aircraft has its sea legs.

The prototype X-47B Unmanned Combat Air System(PDF) this week completed its first at-sea tests as it gets ready to take off from and land on an aircraft carrier sometime in 2013, a first in naval aviation history.

That eventual flight will be the big moment for the X-47B. But the test phase that just ended is no small potatoes. It's a tricky thing for any aircraft to maneuver around the hectic, cramped, and crowded space of a carrier flight deck. In the test phase that just … Read more

OK, so it was on dry land, not on an aircraft carrier. But first steps are first steps.

On Thursday, the U.S. Navy carried out its first-ever steam catapult launch of the X-47B Unmanned Combat Air System -- see the video embedded below -- and was apparently quite happy with the way things turned out. Before the UCAS demonstrator can make an actual take-off from a carrier, it needs to show that it can handle the unique rigors of being flung slingshot-style into the air instead of making a more leisurely jaunt down a runway.

"This test, in … Read more

How do you drive a jet-powered drone around the deck of an aircraft carrier? If you've ever guided a remote-control toy car around your kitchen floor, you'll have an idea.

Northrop Grumman said today that it has done its first shore-based tests of a wireless handheld controller that can steer its X-47B unmanned aerial vehicle, a key step toward getting the UAV ready for flight tests on an aircraft carrier in 2013.

In the trial run, which took place earlier this month, Northrop Grumman and the U.S. Navy used the project's Control Display Unit to roll … Read more

Northrop Grumman's X-47B unmanned stealth plane achieved cruise mode flight for the first time recently, a major step toward using the bomber aboard aircraft carriers.

During a flight at Edwards Air Force Base on September 30, the robo-plane retracted its landing gear and flew in cruise configuration for the first time. The test helped prove its navigation hardware and software.

The flight was part of the X-47B's "envelope expansion" under the Navy's Unmanned Combat Air System Carrier Demonstration (UCAS-D) program. Northrop has produced two X-47Bs for the Navy and the aircraft is slated to begin carrier trials in 2013. … Read more

Almost from the very beginning seven decades ago, flying wings have been something of a specialty for the aircraft company founded by Jack Northrop.

The 1940s saw the XB-35 experimental aircraft. The late 1980s brought the B-2 bomber.

Now Northrop Grumman is pushing ahead with the X-47B UCAS (for unmanned combat air system), a prototype going through its fledgling stage en route to the goal of demonstrating in 2013 that an unmanned, tailless, strike fighter-size aircraft can land on and take off from an aircraft carrier.

Earlier this month, the X-47B made just the second and third flights (from dry … Read more

Only six years after the film "Stealth," Northrop Grumman has demonstrated its much ballyhooed X-47B robot stealth plane, successfully completing a 29-minute test flight to 5,000 feet at Edwards Air Force Base in California.

Developed under a $635 million Navy contract, the unmanned, tailless jet provides greater range and power by taking off from aircraft carriers, delivering laser-guided bombs and refueling in the air.

The test flight, which had been expected to take place over a year ago, is a first step to demonstrating the plane on a carrier. Northrop Grumman now says that will happen in … Read more

Construction of the X-47B unmanned, tailless, stealth jet is ahead of schedule, with the first flight scheduled for November 2009, reports defense contractor Northrop Grumman.(pdf)

The X-47B is expected to be the first tailless UAV jet to operate off an aircraft carrier, which includes catapult launches and arrested landings; to do that it will also need to be capable of maneuvering precisely and autonomous around the flight deck. But none of that is expected to happen until sea trials in 2011.

The plane, developed under the Unmanned Combat Air System Carrier Demonstration (UCAS-D) program, has the "potential to … Read more
