The vast majority of the 200-plus UAVs in use in the United States are military craft. But the 11-model civilian fleet is expected to grow. The planes below – drawn to scale – are all operational and represent the future of unmanned flight.Global ObserverMedia Platforms Design TeamPowered by a liquid hydrogen fuel cell, California-based AeroVironment’s UAV can stay aloft for a week at 65,000 ft., providing low-cost communications relays and aerial mapping. style=“float:right; font-size:9pt; font-weight:bold; border:thin solid #666666;"> Civilian UAVsMedia Platforms Design TeamNo Pilot, No ProblemMedia Platforms Design TeamAnatomy of a PredatorMedia Platforms Design Team Civilian UAVs: Five More Unmanned Aircraft frameborder=“0” scrolling=“no”»Media Platforms Design TeamBell Eagle EyeMedia Platforms Design TeamThe Bell is a two-in-one craft: Launching vertically like a helicopter off boat decks for search-and-rescue missions, it turns into a fixed-wing plane for long-range operations (up to 100 nautical miles). style=“float:right; font-size:9pt; font-weight:bold; border:thin solid #666666;"> Civilian UAVsMedia Platforms Design TeamNo Pilot, No ProblemMedia Platforms Design TeamAnatomy of a PredatorMedia Platforms Design Team Civilian UAVs: Five More Unmanned Aircraft>Media Platforms Design TeamMedia Platforms Design TeamKillerBee 4Media Platforms Design TeamA civilian version of the KB4 is used to track icebergs.
