Russia says intercepted US drone over Crimea: arms group
"The drone was flying at about 4,000 metres (12,000 feet) and was virtually invisible from the ground. It was possible to break the link with US operators with complex radio-electronic" technology, said Rostec in a statement.
"Judging by its identification number, UAV MQ-5B belonged to the 66th American Reconnaissance Brigade, based in Bavaria," Rostec said on its website, which also carried a picture of what it said was the captured drone.
The photograph appeared to show an apparently armed drone in flight, rather than debris.
The Crimean port of Sevastopol is home to Russia's Black Sea Fleet, which is believed to be equipped with detection equipment.
Crimea, where pro-Kremlin forces have control, is to hold a referendum on Sunday on the peninsula joining Russia, in what Moscow says is a fair expression of self identity but the West views as an illegal annexation of sovereign territory.
