About the Orlan drone

The Orlan-10 is a reconnaissance, unmanned aerial vehicle (UAV) developed by the Special Technology Center (STC) in Saint Petersburg for the Russian Armed Forces. The Orlan-10 features a composite hull that reduces its radar signature.

Drones are usually deployed in groups of two or three; the first is used for reconnaissance at a height of 1,000 to 1,500 metres (3,300 to 4,900 ft), the second for electronic warfare and the third as a data relay. One system can include up to five vehicles.
