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 used Krasukha-4 electronic-warfare systems during the full-scale invasion phase: Ukrainian forces captured a 1RL257 Krasukha-4 command-post module near Kyiv in March 2022, later reporting documented a Russian Krasukha-4 destroyed in Zaporizhia region in November 2023, and March-April 2024 reporting described Krasukha-4 use in Donbas and southern Ukraine for radar, missile, UAV, and communications disruption.
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.
Open 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 family branch rather than a Krasukha-4 variant row.
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.
VPK.name reports that work on the Krasukha-2 and Krasukha-4 complexes began in the mid-1990s, with Gradient, Kvant, Bryansk Electromechanical Plant, and KRET entities tied to the development and production chain.
