Triton is a large drone. At 130 feet, it's wingspan is over twice as long as that of the iconic Predator. It's much closer to the Air Force's long-endurance Global Hawk surveillance drone, only outfitted to fly over sea instead of desert. This week, it completed an 11-hour 3,790 mile flight from Palmdale, California, to the southern U.S. border, the Gulf of Mexico and across Florida, before reaching its destination at the Patuxent River naval base. Long-endurance flights over land and water mean that, when adopted by the service, the Triton can watch great swathes of the ocean for anything that looks like a threat to America's Navy.
