Ha, I've been saying for a while now that just such a thing is going to be declassified soon. My generations SR-71... equal parts beautiful and horrifying. For the cost of one fighter jet you could have a swarm of air-to-air/land combat vehicles with semi-autonomous swarm intelligence attack and harry enemies into submission. Air supremacy would be a doddle with a drone that can pull orders of magnitude more G and react almost instantaneously compared to a manned fighter. The last time something so disruptive came along was during the dark days of WW1 (machine gun) and WW2 (aircraft)... don't get me started on WW3... but this next one is shaping up to be a real nice specimen for our peace loving super advanced cybernetic progeny. I, for one, welcome our new overlords. ----- EDIT ----- although to actually answer your question as I think it would be an interesting thought experiment: The laser technology I've been hearing about recently has been fascinating - the pope protector, Roman Abramovic's boat, the TOF mapping devices used on automatic cars/trucks. And other technology seems to be coming of age too with microwave guns used for riot control and rail guns seem inevitable. Although unlikely to help in this situation, I don't think anyone here can begrudge me a rail gun on my hypothetical throne of warfare!?
