The drone is just the first piece in what the Navy calls Broad Area Maritime Surveillance, or BAMS. The MQ-4C Triton will be used to keep tabs on a wide area using “radar, infrared sensors and advanced cameras to provide full-motion video and photographs to the military,” according to The Washington Post. Eventually, a network of these drones could be deployed to fly around the world and provide 24-hour, 7-day-a-week coverage of a given area.
