A leaked US military assessment says the Chinese military may soon deploy a high-altitude spy drone that travels at least three times the speed of sound, the Washington Post reported late on Tuesday.
The newspaper cited a secret document from the National Geospatial-Intelligence Agency.
The document, which Reuters could not confirm or verify independently, features satellite imagery dated Aug 9 that shows two WZ-8 rocket-propelled reconnaissance drones at an air base in eastern China, about 350 miles (560km) inland from Shanghai, according to the newspaper.
