A week ago I read a quite interesting blog entry about new winglet designs. Can't find it now, but according to that blog, it seems to be the 'holy grail' in present aerospace engineering .  :)

Interestingly enough, when Global Hawk originally won the Tier II+ ACTD, it was pointed out in AWS&T and other places that it was designed with hardpoints for decoys or ordinance. Since then I've rarely seen this mentioned.

I think it has to do a lot with the philosophy, that the Global Hawk is a pure reconnaissance platform, nothing more. During the time when the Predator received its first weapons, I remember the same idea to do so with the Global Hawk. But the USAF and some other institutions killed that idea even before the initial study was done, because they didn't want to see not even the indication, that the Global Hawk is able to use weapons.

It seems to be a reasonable. When the Global Hawk is shooted down in the enemy territory, it is much easier to say that we were only observing than to say, that we had there the armed vehicle, that is able to attack you in any time. Remember, that Global Hawk is strategic reconnaissance plane compared to Predator.

New Lock-Mart UAV:

Lockheed's New Stealth Drone  by Steve Trimble, via Danger Room

http://www.popsci.com/files/imagecache/article_image_large/files/articles/lockdrone.jpg

After almost 15 years of spying on America's enemies, and occasionally
blowing them up, the venerable Predator and Reaper drones currently used by
the Air Force will have to be replaced, sooner or later. The Pentagon has
put out a contract for the next generation of UAVs, and Stephen Trimble of
The DEW Line has the first shots of Lockheed Martin's stealthy entry, the
MQ-X.
The new UAV would have stealth features, the ability to fly at 0.8 Mach and
a 24-hour flight life. For comparison, that's twice as fast as the Reaper,
and almost six times as fast as the Predator, with comparable flight life.
Other than that, Lockheed hasn't released any details. However, as noted by
the folks at Danger Room, Lockheed seemingly stopped making drones, so the
appearance of any entry into this contest comes as a surprise.
Lockheed has some stiff competition in the battle to replace the Predator
and Reaper drones. General Atomics, the company that makes the Predator,
looks to hold onto its UAV contract, while Boeing, Raytheon and Northrop
Grumman certainly want to get into this lucrative market.
The competition doesn't begin until next year, and even then, the project
won't receive funding until 2012. Ultimately, the Air Force hopes to have
this new generation of larger, more capable UAVs in the sky by 2020.
Hopefully, by then they will have solved the "linkage" problems.

Anyone seen a better image of this one?

Enjoy the Day! Mark

Nice pic and concept, but a picture without a caption is a pretty useless thing...

Looks very similar (but not identical) to Lockheed Multi Role Endurance (MRE)....Other similar pictures are somewhere else on the forum.
I saw this first maybe in 2002. Funny they would choose to arm it with a Phoenix (I can only assume that's what it is), which was already outdated back then.

I heard it mentioned in connection to the Lockheed RIVET design.

You mean Dan Raymer's Reverse Installation Vectored Engine Thrust? The one concept i saw was manned, and looked a bit different.

Its the UCAV design from Lockheed. As AeroFranz wrote, similar, but not identical. The shape of the wing, tail and air intake is different.
