The head of Army Space and Missile Command on Tuesday laid out a five-year plan for testing high-energy lasers that would be powerful enough to take down enemy aircraft.

Army officials recently participated in a series of tests involving the Mobile Expeditionary High-Energy 5 Kilowatt Laser and the service’s Heavy Expanded Mobile Tactical Truck 10 Kilowatt Laser at Hard Kill Challenge, an exercise to test counter-unmanned aerial system technology.

“Both of the laser systems were highly successful,” Lt. Gen. James H. Dickinson, Commanding General, United States Army Space and Missile Defense Command and Army Forces Strategic Command, told an audience at the Association of the United States Army’s 299th Institute of Land Warfare Breakfast.
