Drones on the WaterThe U650 amphibious UAV is the size of a Predator drone or Cessna utility aircraft, but its carbon fiber construction saves weight, thus increasing its buoyancy and fuel efficiency.
The U560 amphibious drone recently completed its first test flight reports Liberation Daily News, a Chinese newspaper. Flying off of a lake in Jiangsu province, the drone's flight took 30 minutes.
Despite being amphibious, the U560's top speed of 260km per hour is faster than the Predator's 217 km per hour maximum speed. Liberation Daily News also noted that the U560 uses satellite communications, datalinks and a measure of autonomy to fly reconnaissance missions with minimal human input, such as using cameras and radar to patrol preselected areas of water for submarine periscopes. The U650 is likely derived from the S-100, another Vita Smart Systems Limited/UVS amphibious drone that debuted at the 2014 Zhuhai Air Show (the U650's landing gear is retractable).
There is no real comparable amphibious drone in the US system. If the PLAN picks up use of the U560, its large size and amphibious takeoff/landing capabilities could offer Chinese surface warships a fast off board reconnaissance capability, with quite different range and capability than the helicopters, manned and soon unmanned that the US Navy has on board its ships. For instance, a Type 052D guided missile destroyer could hoist a U560 drone onto the water and send it off on a longer range hunt for enemy submarines, warships and missile launchers, or even conduct electronic warfare (much how World War II battleships used seaplanes to scout ahead). The U560's amphibious and autonomous capabilities also mean that it could be used to supply Chinese island garrisons with a heavy UAV capability.
