The U.S. Navy says it has landed a drone the size of a fighter jet on an aircraft carrier for the first time. The X-47B experimental aircraft made the landing Wednesday afternoon, a milestone that showcases the military’s capability to have a computer program perform one of the most difficult tasks a pilot is asked to do. The Navy can now move forward with plans to develop another unmanned aircraft that can provide around-the-clock surveillance while also possessing strike capability. Critics in the U.S. and abroad have charged that drone strikes cause widespread civilian deaths and are conducted with inadequate oversight. Still, defense analysts say drones are the future of warfare.
