Defense Advanced Research Projects Agency (DARPA) is taking autonomous robots to the next level.
The Vulture is an Unmanned Ariel Vehicle that can go up and stay up for five years without refueling or landing. How long before it is a persistent weapons platform!!??
"Vulture technology enables a re-taskable, persistent pseudo-satellite capability, in an aircraft package. The technology combines the key benefits of an aircraft (flexibility & responsiveness, sensor resolution, reduced transmit/receive power, affordability) with the benefits of space assets (on-station persistence, no logistics tail, energy independence, fleet size, absence of in-country footprint)."
--There is no fate but what we make for ourselves...
