The 1RL257 Krasukha-4 is a Russian mobile ground-based electronic-warfare system built to detect and jam airborne, ground, and satellite-linked radar systems. Public references identify it as the Krasukha family member focused on X/Ku-band fire-control and surveillance radars, with open-source range claims commonly presented as a 150 to 300 km class capability.
Russian forces fielded Krasukha-4 during the full-scale invasion of Ukraine: Ukrainian forces captured a 1RL257 Krasukha-4 command-post module near Kyiv in March 2022, Ukrainian reporting documented a Russian Krasukha-4 destroyed in Zaporizhzhia region on November 1, 2023, and 2024 reporting described Russian Krasukha-4 use in Donbas and southern Ukraine against radar-guided weapons, radar targets, UAV sensors, and communications.
Role detailsRussian forces deployed Krasukha-4 to Khmeimim airbase near Latakia by October 2015 as part of the electronic-warfare and air-defense package protecting the base during the Syria campaign.
Role detailsOpen sources describe Krasukha as a family rather than a single vehicle. This record keeps the 1RL257 Krasukha-4 scope separate from Krasukha-2/1L269 because the public descriptions give the two systems different radar-band targets and configurations.
ICDS lists 1RL257 Krasukha-C4 as designed to jam X/Ku-band fire-control radars, while VPK.name describes Krasukha-4 as a two-vehicle KAMAZ-6350 complex.
ICDS separately lists 1L269 Krasukha-2-O as an S-band radar jammer, so this page treats it as an adjacent Krasukha family branch rather than the same 1RL257 system.
Public sources point to Bryansk Electromechanical Plant, KRET, Gradient, and Kvant in the program chain. The catalog uses its Rostec-affiliated Russian defense-industry facet because the sourced chain runs through KRET and BEMZ rather than one standalone public builder profile.
Krasukha-4 is best documented in open sources as a Russian state-defense-order electronic-warfare system with later export exposure. Rostec's 2013 release ties production and handover work to KRET and Bryansk Electromechanical Plant, while U.S. Army ODIN identifies the 1RL257E as an 8x8 mobile multifunctional jammer.
Rostec reported that KRET completed a 2013 Ministry of Defense contract and that BEMZ finished two Krasukha-4 complexes as part of that year's state-defense-order production.
Defense reporting from Serbia's 2025 Belgrade parade identified elements of the 1RL257 Krasukha-4 among Russian-supplied electronic-warfare systems shown alongside Krasukha-2 and Moskva-1 equipment.
A 2024 CNS report placed a Russian 1RL257 Krasukha-4 in commercial satellite imagery at Bandar Abbas and discussed Iranian Cobra V8 comparisons, while warning that reverse-engineering claims remain unproven.
TASS reported a first Krasukha export contract in 2021 and unnamed later orders in Southeast Asia and Eastern Europe. This page treats those reports as export background, not conflict-use evidence.
Public sources describe Krasukha as a family rather than one vehicle. This record covers the 1RL257/1RL257E Krasukha-4 branch and lists Krasukha-2 only as an adjacent family designation.
