RUTANS ARES EMERGES FROM PAUL ALLENS HANGAR
Turbofan Killer Bee: Rutan ARES "Mudfighter" for U.S. Army Close Air Support
Not armored like the A-10 which is why it didn’t go anywhere at the time. Makes sense as a UAV, though that’s still not as good as manned CAS until AI gets better.
The only thing that Burt did not address is the armored tub as in the A-10 although he did address the armored surge cell for the fuel delivery. Outside of that, if there were a replacement for the Warthog, a very good start.
