Belarus Introduces New UAS and EW Jammers

With a payload capacity of less than 10 pounds, the UAS can drop four hand grenades, a small incendiary bomb, or a PTAB-2.5 anti-tank bomb. It can approach as near as 20 meters (60 feet) to its target before its motor becomes audible, claims the manufacturer-developer, KB Radar Design Bureau.

A new handheld radio-electronic warfare/jammer system from KB Radar was unveiled at MILEX. Weighing 6.5 kg (14 pounds) the battery-powered Groza-R2 is a development of the 18-kg Groza-R, with an effective range of more than 3,000 meters (9,000 feet). This was introduced during the 2017 IDEX show in Abu Dhabi. Following feedback from the military and the security services that they would favor a smaller, lighter, handheld version—albeit with reduced range—KB Radar Design Bureau developed the Groza-R2. Company sources at KB Radar said that a newer version of the system is under development. It is being adapted to urban warfare conditions and the protection of sensitive buildings against attacks by single and swarming UASs.

The Groza family of jammer transmitters is mostly intended for use against mass-produced, cheaper drones that pose a security threat to sensitive buildings, installations, and events. The guaranteed jamming range (against both satellite radio navigation and UAS control channels) is approximately 500 meters. Covered command and control (C2) frequency bands are in the range of 2.4 to 2.480 GHz and 5.725 to 5.850 GHz. Groza-R2 is capable of suppressing the UAS’ onboard GPS and Glonass satellite navigation systems. The frequency band of satellite radio navigation systems covered is 1.57 to 1.61GHz. Continuous jamming (radiation) time is 30 minutes.
