The Orlan-10 (Russian: Орлан-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 fuselage 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.
