Russian enterprises have begun developing the latest long-range radar surveillance complex based on a helicopter-type drone, a source in the military-industrial complex told RIA Novosti on Saturday.

Since November, the development of an unmanned helicopter for a long-range radar patrol has been underway, which will track small-sized and low-speed enemy drones at low and extremely low altitudes and provide guidance to them with anti-aircraft missile systems of the military air defense, the source said.

The source noted that the work on the complex was initiated on the basis of an analysis of the experience of recent local conflicts, which shows the increased role of attack drones. The development, according to the source, is being carried out on the basis of the existing groundwork, so the complex will be created as soon as possible.

During the aggravation of the Nagorno-Karabakh conflict in September-November of this year, various types of drones were actively used.

Attack drones and kamikaze drones have been actively used in recent years in other regions as well.
