Images from Russia’s major ‘Vostok 2018’ exercise on 13 September appear to show a production version of the REX-1 counter-unmanned aerial vehicle (UAV) weapon in use by Russian Federation airborne troops.
The REX-1 is a rifle-like, man-portable jammer developed by Kalashnikov Group subsidiary ZALA Aero Group and first seen at a Russian defence exhibition in 2017. It does not appear to have a kinetic kill mechanism, relying on the jammer’s ability to cut the UAV off from its operator, communications bearer, and autonomous navigation capability to neutralise the threat.
Specifications data indicate that it operates in the 2.4 GHz and 5.8 GHz ranges, which are commonly associated with wireless and mobile telephone operations, as well as global navigation satellite systems (GNSS), such as BeiDou, Galileo, GLONASS and GPS.
