U.S. Unmanned Combat Aerial Vehicle X-47


Tests are still being performed on this new UCAV.

The Navy, after seeing the Air Force's plans for an ambitious Unmanned Combat Aerial Vehicle, issued a requirement for its own UCAV. Unlike the X-45, the naval UCAV would need to land on an aircraft carrier and overcome the substantial engineering challenges of that requirement. Northrop Grumman has risen to the occasion with its X-47 Pegasus.

The X-47 is a kite-shaped UAV that will demonstrate autonomous flight, takeoffs, and landings. The plane has currently progressed through its taxi testing, in preparation for a first flight. Prior to the aircraft's unveiling, Northrop Grumman used an F/A-18 Hornet to validate the aircraft's GPS-based carrier landing system.

If Northrop Grumman is selcted to build the naval UCAV, the production X-47 will be larger and incorporate a greater degree of stealth, particularly in the intake, exhaust, and radar-absorbing skin coatings.

X-47 first flight is gone very well
Precision landings, precision touch and go, cruise flight and agility.
All well done more than the waiting performance it outperformed the design and it could be better than today easily.(more Agile)

This is only the first generation of unmanned combat aerial vehicles.

The 2nd and 3rd generation vehicles should be far, far superior (fast, stealthy, agile, smart).

It's just a matter of time.

Do you know the Mines?

They are like the UCAV or UCV or UCSSS.

UCAV = Unmanned Combat Air Vehicles
UCV = Unmanned Combat Vehicles
UCSSS = Unmanned Combat support surveillance and Suppression (fix)

MINES = UNMANNED COMBAT SUPPRESSION

NONE OF THE ABOVE KNOW ALWAYS FRIEND OR FOE LIKE HUMAN PEOPLE (Failures, Malfanctions, Out of Control and Order).

The MINES don't recognize FRIEND and FOE or ADULT and CHILD.

UCAV, UCV, UCSSS are like the MINES.

TRY TO FIND YOUR SUM.

MINES ARE BANNED FROM MOST OF THE COUNTRIES OF THE WORLD.

They are MOBILE MINES more dangerous than a NUKE.

At the moment X-47 is only a UAV (Unmanned air vehicle) a technology demonstrator of Unmanned Air Vehicle.

The UAV is not at the moment a UCAV it could be an airplane in the future.

An UCAV Bomber is more dangerous than a Nuke.

A Cruise Missile is an UCAV BOMBER.

These UCAVs will have the ability to identify friend or foe.

They will most likely use the same secure system that is installed in US fighters. The system identifies the fighter as a friend so it won't be shot down by surface-to-air missiles or other friendly aircraft.

A UCAV is not a dumb mine.

I would consider a UCAV as a smart flying watch dog.

Just send it up in the air to patrol a certain territory. If an enemy enters the territory, then it will attack. If a friend enters the territory, then it will not do anything but keep watch.

They aren't more dangerous than a nuke. That is stupidity.

There is the Jamming Technology on air I don't tell dumb fables.

The first Unmanned vehicles were on ground and not on air.
Only few people knows about the experiments and the results.

They are more dangerous than mines.

Try to defuse a mobile Mine if you want.

Read the original first flight press release:

NORTHROP GRUMMAN'S X-47A PEGASUS FIRST FLIGHT ACHIEVES MILESTONE IN AUTONOMOUS CONTROL
CHINA LAKE, Calif. -- Feb. 23, 2003 -- Northrop Grumman Corporation's (NYSE: NOC) Integrated Systems sector achieved a significant milestone in autonomously controlled flight today with the successful first flight of its Pegasus experimental unmanned air vehicle (UAV). The flight took place at Naval Air Warfare Center-Weapons Division, China Lake, Calif

Northrop Grumman designed and built the Pegasus X-47A with its own funds to demonstrate low-cost, rapid prototyping; robust unmanned vehicle management; and tailless aerodynamic qualities suitable for autonomous launch and recovery flight operations from an aircraft carrier. Lessons learned from the development and testing of Pegasus will be used in support of the company's naval unmanned combat air vehicle (UCAV-N) program for the U.S. Defense Advanced Research Projects Agency (DARPA) and the U.S. Navy.

Today's flight began at 7:56 a.m. PST and lasted 12 minutes. Specific test objectives included low-speed handling qualities, air vehicle performance, navigation performance and collection of landing dispersion data. All test objectives were met.

Most significantly, the X-47A successfully landed near a predesignated touchdown point to simulate the tailhook arrestment point on a carrier flight deck. This landing data, coupled with subsequent flight touchdown points, will demonstrate the X-47A system's landing accuracy potential. The shipboard-relative global positioning satellite system was used as the primary navigation source for increased landing precision.

Built largely with composite materials and powered by a Pratt & Whitney JT15D-5C engine providing 3,200 pounds of thrust, Pegasus measures 27.9 feet long with a nearly equal wingspan of 27.8 feet. The X-47A incorporates advanced autonomous flight control laws to account for directional control of its tailless design.

"The Pegasus program represents our commitment to significantly reduce the risk for our DARPA and Navy customers on the UCAV-N program," said Gary W. Ervin, Northrop Grumman Integrated Systems sector vice president for Air Combat Systems. "Regular unmanned flight operations aboard a flight deck at sea have never been attempted, and Pegasus addressed some of those key concerns today.

"In addition, today's event leverages Northrop Grumman's experience with thousands of hours of autonomous flight by unmanned systems such as Global Hawk and Fire Scout," Ervin said. "Our approach to design from a 'system' perspective is reflected in our success with a full range of UAVs, and Pegasus is a logical progression in repeatable performance with a complex aerodynamic shape. This success also points to the potential for joint use of the Pegasus design to meet Air Force requirements in the government's emerging Joint UCAV program."

The goal of the joint DARPA/Navy UCAV-N program is to demonstrate the technical feasibility for an unmanned system to effectively and affordably conduct sea-based surveillance, strike and suppression of enemy air defenses missions within the emerging global command and control architecture. The Pegasus program will play a significant role in supporting this effort.

The X-47A was designed in El Segundo at the Air Combat Systems business area of Northrop Grumman Integrated Systems. The vehicle was built at Scaled Composites in Mojave, Calif.

Northrop Grumman Integrated Systems, headquartered in El Segundo, Calif., is a premier aerospace and defense systems integration enterprise with the capabilities to design, develop, produce and support fully missionized integrated systems and subsystems. Integrated Systems delivers best-value solutions, products and services in support of chosen segments within the broad market areas of battlespace awareness, command and control systems and integrated combat systems.

Someone play a dirty game on war forum.

MINES = UNMANNED COMBAT SURVEILANCE AND SUPPRESSION SYSTEMS WITHOUT FRIEND OR FOE DISTINGUISH

UCV = UNMANNED COMBAT VEHICLES WITHOUT DISTINGUISH BETWEEN A MAN OR A CHILD, WITHOUT DISTINGUISH BETWEEN A SOLDIER OR A CIVIL ONE (VEHICLES WHEELED OR TRACKED with guns and missiles).

FUCSSS = FIXED UNMANNED COMBAT SURVEILANCE AND SUPPRESSION SYSTEMS ( Camo Rotating Turrets inside the ground with Guns and Missiles AT ) WITHOUT DISTINGUISH MAN ELDER CHILD SOLDIER LIKE THE MINES.

UCAV = UNMANNED COMBAT AERIAL VEHICLES much better call they UCA = UNMANNED COMBAT AIRCRAFT (Fighters or Fighters-Bomber, Bombers, Choppers)

UCS = UNMANNED COMBAT SHIPS (Unmanned Submarines)

EVERYONE WITHOUT AN IFF SYSTEM IS A TARGET/GOAL TO DESTROY SOLDIER OR CIVIL ONE.

I've only told that they are all MINES and the MINES ARE BANNED IN MOST ( a lot) COUNTRIES IN THE WORLD.

This is the AI level of performance yesterday (more of 20 years ago) like today.

AI = ROBOT

Don't you like the true Admin?

IT COULD BE BETTER :P

More Agile if we can modify something in the wings.

Bye-Bye
