Air Force Purchase of Chinese Drones Spurs Security Concerns

The U.S. Air Force recently bought dozens of Chinese-made drones to use for testing and training, according to officials and records of the purchase, fueling concerns about continued Defense Department use of technology that lawmakers consider a threat to national security. The Air Force Special Operations Command, the service's highly trained commando division, bought 57 drones in September from Da-Jiang Innovations, or DJI, the world's largest maker of unmanned aerial systems, based in Shenzhen, China.
