In Central Asia, a hidden pipeline supplies Russia with banned tech

On the shipping label, the Chinese drones were billed as heavy-duty crop-dusters, the kind used by orchards and big farms. But the identity of the buyer — a Russian company that purchased a truckload of the aircraft in early May at nearly $14,000 each — hinted at other possible uses.

The drones’ potential military value, ironically, had been noted by Russia’s government, which last year seized four aircraft of the same model in eastern Ukraine and claimed that Kyiv was planning to use them for chemical warfare. The sturdy all-weather quadcopters are built to carry payloads of nearly 70 pounds and are designed to glide at treetop level trailing a fog of liquid chemicals.
