1RL257E Krasukha-4 Russian 8x8 Mobile Multifunctional Jammer

The Krasuha-4 is a broadband, multifunctional jamming system designed to neutralize LEO spy satellites, such as the US Lacrosse/Onyx series, as well as ground-based radars, airborne surveillance radars, and radar-guided ordinance at ranges between 150–300 km. It may also cause damage to enemy radar, electronic warfare, and communications systems. The complex functioning is based on creating powerful jamming at the fundamental radar frequencies and other radio-emitting sources. For jamming of airborne radars to protect the land assets against airborne threats by observing them using radar, the ground jamming unit performs the following tasks: Detection, processing, analysis, and recognition of signals embedded in the operating range of frequencies; and suppression of the main and side-lobe antenna signals of ground-based radars for protection against airborne threats such as anti-radiation missiles (ARMs). The Krasuha-4 EW equipment is mounted on two KAMAZ-6350 vehicles. The complex 1RL257 features two trailers equipped with specialized equipment. Both trailers are equipped with complex electronic equipment and antennas of various designs. One trailer features an antenna unit mounted on a sliding bar, apparently designed for communication. On the roof of the second trailer a set of antennas is mounted in a distinctive configuration. The three parabolic antennas can be rotated in any direction and at a desired elevation. Thus, the complex EW "Krasuha-4" is capable of transmitting radio signals without restrictions in azimuth and elevation. Both machines utilize complex digital equipment with high-performance characteristics, including the Baguette-23B computer. --- COGINT Report Data (7 June 2023, UNCLASSIFIED) --- Bandwidth/Frequencies: Jamming X-band, 8.5–10.7GHz and Ku-band, 13.4–17.7GHz Range: 150–300 km Performance Specifications: • Jamming frequency range, GHz: X-band, 8.5–10.7; Ku-band, 13.4–17.7 • Speed [km/h]: 115 • Range [km]: 850 • Weight [kg]: 35,000 • Length [m]: 11.3 • Width [m]: 9.0 • Height [m]: 5.5 • Crew [people]: 4
