USAF Acknowledges Beam Weapon Readiness
This sounds like something from science fiction but may soon be an operational capability (if it isn't already). These are non-lethal high energy microwave weapons designed to damage an enemy's electronic systems.
"Power levels for HPM weapons are increasing. The report said one microwave source weighing less that 45 lb. radiated 1 gigawatt of power within a few nanoseconds. A 400-lb. system radiated 20 gigawatts. The report noted that Hoover Dam generates 2 gigawatts per day. The HPM weapon would draw power from the air vehicle's engines, which would let it make a number of attacks during a mission."
