Even if the thick delta top mounted wing would greatly solve many problems inherent to that kind of fighter. Even more than now the full carbon skin problem would be far more easy to solve (or sub-contracted “cheaply” to a Dassault/Boeing and alikes).
The wing is thick because it has a supercritical profile. Report on Thermoplastic wing skin technology. [Link]
With all things being equal, don’t high wing fighters have a lower roll rate and are therefore less maneuverable?
Stability (dihedral effect) of high wing configuration is reduced with an anhedral angle in the wing. Same as the Harrier.

I think the main purpose of the X-47B’s sense and avoid system is for automated aerial refueling. IOC of the Global Hawk’s automated collision avoidance system is planned for 2017. [aviationweek.com]
These passive systems turn the tables against UHF/VHF jammers as well.

Looks like the aircraft shares the same wing planform as the Boeing Phantom Ray and Dassault nEUROn but it has less sweep, more sweep is better from the viewpoint of RCS reduction.
The canards are edge aligned with and on the same level as the main wing as they are attached to a LERX. The nose cone appears to be edge aligned with the intake edge.
Serpentine duct has its bad points too, more internal volume and structure needed which reduces space for fuel and increases weight. Greater internal volume needed makes it harder to optimize for external aerodynamic shape. S-ducts can also affect the pressure recovery. The aircraft has DSI bumps which some will like. 😀
The marking is the new logo of Boeing’s Phantom Works. It looks like a stylized P.


Indra develops the first high-resolution Passive RADAR system [Indra]
Indra has recently completed the development and demonstration of the functionalities of a passive high-resolution primary radar system. The project was sponsored by the European Defence Agency (EDA). This is the first passive system in the world that is capable of offering images with the application of inverse synthetic aperture radar (ISAR) techniques.

No? Then what continent is this island part of, & within sight of the mainland of?
It was not meant to be taken seriously..:)
US Army completes initial tests on Block III Apache [Flightglobal]
Any Block III can accept either radar or UTA – or neither, if the commander so chooses, according to Lt Col Dan Bailey, the army’s Block III product manager.
The system allows Block III pilots to control the sensors and weapons on a Gray Eagle or direct its path. Eventually pilots will be able to control an AAI RQ-7 Shadow UAV, once it is upgraded to use the Ku-band data-link, Bailey adds.
Its unlikely that the US will export this kind of technology though..
if I was looking for a battle field helicopter I would go for Lynx wildcat not a true attack helicopter but it is all weather day and night capable has a good weapon system can carry troops and under slug loads plus operate off the back of a ship its an outstanding all round helicopter
I think a multirole helicopter like Lynx wildcat combined with a UAS like the Gray Eagle would be a good solution. More flexible than a dedicated attack helicopter.

They’ve tested the X-47B’s systems on a surrogate F/A-18.
The U.S. Navy just got a little closer to its goal of routinely flying combat drones off carriers by the close of the decade when an F/A-18 Hornet landed itself on the deck of the USS Dwight D. Eisenhower (CVN-69) using flight control software designed for the Northrop-Grumman-built X-47B Unmanned Combat Air System Demonstrator or UCAS-D.
“There is no remote control, meaning there is no joystick, there’s no one that’s flying this aircraft from the carrier, we give it commands via the network we have in place … tying in with existing carrier systems and then the aircraft executes those commands.”
