New Drones for the Military

I am completely unprepared to write about air or space today. I'll do the best I can.

The LA Times has an article about the next generation of unmanned aerial vehicles slated for use in the military. Three vehicles are discussed, briefly; the Global Observer, the the X-47B, and the Phantom Ray.

The Global Observer is a massive aircraft with four almost comical-looking propeller engines, each having two blades. It looks like a single-winged Dornier creation out of the early Twenties. Powered by liquid hydrogen (just like the Shuttle) and boasting a wingspan comparable to that of an early model Boeing 747, the Global Observer is designed to loiter at 65,000 feet for periods of up to a week. On-board cameras can take a single image that's larger than Afghanistan (though there's no information of the resolution of this image). This functionality will allow military commanders and political leaders to essentially see what's going on in the world's hot spots at a given time, in real time (or near-real time), on one big image.

The X-47B looks like something Batman would fly. Stealthy, angular at the leading edge, with an air intake where you would expect the cockpit, and able to carry two JDAM weapons for use against transient targets of opportunity. The X-47B's claim to fame is that it can conduct operations from an aircraft carrier, giving it a very quick strike capability and essentially unlimited in-theater endurance. This is what the failed A-12 Flying Dorito would have done for the Navy.

Finally, we come to the Boeing Phantom Ray, which is an outgrowth of the X-45 Program (itself the child of the Bird of Prey stealth demonstrator). Though not designed for any one role, the Phantom Ray could conceivably be adapted to nearly any function short of air superiority. The Ray is about the same size as the X-47B, but carries more payload (up to 8 JDAM weapons) and cruises faster (0.8 Mach vs 0.45 Mach, about the same speed as an airliner). This would seem to make the Phantom Ray the better aircraft from an all-around perspective.

One marked advantage of the latter to aircraft mentioned is the fact that they are turbofan powered instead of propeller-driven. This means that the X-47B and the Phantom Ray can go faster and climb higher than the Predator and Reaper drones in use today. I think it will be interesting to see how quickly these aircraft are brought into the fold and deployed. They *could* save many US lives.
