Troops need various electronic warfare systems, including specialized ones. We need means to counter radar detection systems, as well as to suppress communication channels, including in civilian bands. The electronic warfare RB-341V "Leer-3" complex is intended to terminate communication in GSM networks. In early October, Leer-3 became an exhibit at the Innovation Day of the Southern Military District exhibition.
Officially, the Leer-3 system is referred to as an “aerodynamically throwable transmitter of interference to subscriber terminals of cellular communication of the GSM standard”. In other words, this complex is designed to suppress GSM communications using interference transmitted by a special unmanned aerial vehicle. A special transmitter installed on a lightweight UAV simulates the operation of a cellular network base station and thereby interferes with the normal operation of subscriber terminals.
The Leer-3 complex was developed by the St. Petersburg-based Special Technological Center LLC. The same organization is engaged in the manufacture of serial machines. In the configuration presented at the exhibition, the complex consists of several main elements. The main one is a truck with a van body, in which all the necessary control systems and an antenna-feeder device for communication with drones are mounted. In addition, the base truck is used to transport aircraft in the stowed position.
The RB-341V complex presented at the exhibition is built on the basis of the KamAZ-5350 chassis, which allows it to move on roads and off-road, as well as to arrive in a timely manner in the indicated deployment areas. According to reports, the van with special equipment can be installed on other chassis. Such changes affect exclusively the mobility of the complex in the stowed position.
The Orlan-10 unmanned aerial vehicles should be directly involved in the suppression of radio channels. These drones are equipped with special radio signal transmitters that simulate the operation of base stations of GSM networks and counteract the use of subscriber terminals. Such equipment allows blocking the use of equipment operating in the GSM-900 and GSM-1800 bands. At the same time, it is possible to work in several frequency ranges that completely cover the ranges of cellular networks.
T. N. the transmitters of the virtual base station are located in the fuselage and wing of the UAV. In the first case, the transmitter power exceeds 10 W, in the second - 2 W. This power allows you to effectively block the operation of subscriber equipment within a radius of up to 6 km (fuselage transmitter). The transmitters are capable of blocking the operation of networks of three operators and "serving" up to 2000 subscriber terminals.
The RB-341V complex includes up to two unmanned aerial vehicles. A special inclined launcher is used to launch them. It provides the initial acceleration of the drone, after which it independently makes a flight using the existing engine.
UAV "Orlan-10" is capable of staying in the air for up to 10 hours, carrying a payload weighing up to 4 kg. The maximum speed of the vehicle reaches 150 km / h, cruising speed - 80 km / h. With such characteristics, the Leer-3 complex is capable of solving the assigned tasks for a long time. The total operating time in a given area can be increased by alternately launching several aircraft.
The project of the Leer complex, equipped with unmanned aerial vehicles, was presented several years ago. Later, several modifications of this system appeared, including the "Leer-3". According to available data, the UAVs of these complexes can be equipped with various special equipment, both optoelectronic systems and electronic warfare transmitters.
The RB-341V "Leer-3" complex has already reached mass production and is being supplied to the troops. In October last year, it was reported that the first systems of this type will enter the troops before the end of the year. The first operators of "Leer-3" were supposed to be units of the Eastern Military District. After that, other formations of the armed forces, including the Southern Military District, received similar equipment.
In early October, one of the copies of the "Leer-3" electronic warfare system was sent to the exhibition "The Day of Innovations of the Southern Military District", where it became one of the vivid examples of the development and rearmament of the army. In the exhibition pavilion, a base machine with special equipment was located, and a launcher was deployed. There was an unmanned aerial vehicle with transmitters on it.
