Pole-21 increasingly asserted its place in the Russian military. (Source: Top War) Shield against potential hazards Pole-21 is resistant to high-precision weaponry and other enemy systems using the satellite navigation system. The mission of this combination is to jam and suppress signals from the navigation satellites. In addition, they can accurately detect the enemy’s coordinates, missiles, bombs, aircraft … and handle other assigned combat missions. The weapons complex consists of R-340RP signal reception poles, including the control equipment and interfering antennas, capable of suppressing radio signals at a minimum range of 25km. The combination is capable of suppressing signals from all current navigation systems. The R-340RP antenna stations are mounted on cell towers that are installed at a suitable height or mounted on car chassis with a basin module. Compatibility with various power sources guaranteed. Each pole consumes up to 600 watts of power. Communication between the composite’s components can be maintained through the radio. Therefore, during the installation process it is possible to use GSM antenna as a backup. Pole-21 can be deployed and installed in large numbers over a large area, depending on topography and topography. In favorable areas, a “dome” consisting of 100 antenna columns allows coverage over 22,500 square kilometers. Distribution of Pole-21 In August 2016, Russian media reported that the Pole-21 system was officially preparing to be put into service for the military. In November 2019, the Russian Ministry of Defense announced that Pole-21 had transferred to an electronic warfare unit from the Central Military Zone in charge. Shortly thereafter, in early December 2019, some sources said that the Ministry of Defense continued to deploy the Pole-21 system at base 201 of the armed forces in Tajikistan and operated in alarm mode. In January 2021, the Ministry of Defense announced that by the end of this year, the Central Military Region units would receive 10 additional Pole-21 complexes. These products will be delivered to deployment units in Urals and Siberia. Moreover, Russia also recently officially announced the Pole-21’s presence at the Tartus base in Syria. This system, which works in conjunction with other modern air defense systems, is used to counter potential raids and to prevent potential adversary attacks. In addition, experts from the 49th Army of the Southern Military Region used the Pole-21 combination in training activities. It is known that in the exercise, “Pole-21” mainly confronted the enemy drones. Future protection system The Russian Army Base 201 is the first unit to use this combination. In early January 2020, the system officially worked covering residential areas, armory and locations of important Russian air defense complexes. Through recorded reports, the use of Pole-21 combination in different exercises has brought many positive signals. These products are used independently, or in combination with other electronic warfare systems, completely convenient and effective. In October of last year, Central Military Region troops combined with the “Zhitel” jamming station succeeded in destroying UAV communications. In Tartus, with support from Pole-21, the Ratnik complex. -Kupol suppresses the signals for navigation and control channels. The recent drills in the Southern Military Region demonstrate the Pole-21 system’s capabilities to operate in the reconnaissance and attack lines of the combined armed army. Electronic warfare units act as part of the battalion-level tactical group and protect them from reconnaissance drones. The transfer of the Pole-21M serial electronic warfare system to the military has only started in mid-2019 and was received by subdivisions. It is known that the production and supply of these equipment will continue to develop, of which the Central Military Zone will receive 10 new complexes this year. In the past, the Pole-21 complex has confirmed their ability in trials, as well as their potential in the framework of various scale exercises. In particular its ability to interrupt enemy navigation, interrupt mission execution and ensure the protection of its facilities has been repeatedly demonstrated. It is easy to see that the Pole-21 unit, with all its proven advantages, deserves to be an excellent external signal suppression system, which completes the task perfectly. thanks to its high technical characteristics and mobility. In addition, the principle of preventing satellite positioning is consistent with the current development trends of the military and weapons. (According to Top War)
