Drones are unmanned aerial vehicles that can fly continuously for up to 50 hours, carry 800 kg of missiles, and destroy targets with pinpoint accuracy from miles away. Modern drones use advanced sensors like high resolution cameras and infrared for night vision. They are small, difficult to detect, and can communicate to be controlled by other drones or return automatically if contact is lost. Drones will likely be used in swarms in future conflicts to overwhelm enemies through precise coordinated attacks from many drones.
