U650

The U650 is an unmanned aerial vehicle developed by Vita Smart Systems Limited, an private aerospace firm in China.  The seaplane is 6 meters long and has a wingspan of 12 meters, or roughly the size of a Predator B UAV.  The plane's carbon fibre fuselage gives it a range of 2,000 km on just 150 kilograms of fuel.  The drone made its first 30 minute flight in December 2015 flying from a lake in Jiangsu Province.
