If you can definitively prove the identity of this stealthy unmanned aerial vehicle (UAV), I've got a prize for you.
I snapped this photo at the URS booth at the Air Warfare Symposium on Friday. I have showed it to a lot of people since then, and nobody is exactly sure what aircraft it is. I don't know either. It kind of looks like X-45 and X-47, and kind of doesn't. I was told by the URS staff that the image is a photo of a real UAV, but they didn't know what it was either. URS operates test ranges; it doesn't own or build UAVs. It's possible, of course, this isn't a real UAV at all.
A word about the prize: It is, in my opinion, the best piece of swag handed out at the symposium last week, and will likely become a prized collector's item in any discerning weapon system enthusiast's closet/shoebox/etc.
