The 1L262E Rtut-BM is a Russian tracked electronic-warfare vehicle built around a radio-fuze jammer on the MT-LBu chassis. Rosoboronexport describes the export system as a protective jammer against artillery and mine radio fuzes with a secondary radio-link interference role, while OSCE statements, geolocated reporting, and visual-loss records document Russian Rtut-BM systems in the Russia-Ukraine war.
Russian 1L262E/SPR-2M Rtut-BM systems are documented in the Russia-Ukraine war through Ukrainian official reporting, OSCE-hosted statements, Donbas geolocations, and 2022 loss or capture reporting during the full-scale invasion.
Role detailsThe public conflict record is strongest when the Donbas sightings and 2022 loss/capture evidence are read as separate evidence lanes. Ukrainian OSCE statements reported Rtut-BM movement into Donetsk and a 1L262E identification in northern Luhansk, Ukraine's NSDC later reported Rtut-BM combat use in Donbas, InformNapalm geolocated SPR-2M Rtut-BM imagery in occupied Donbas, and visual-loss reporting placed a 1L262E among Russian equipment destroyed during the full-scale invasion.
Ukrainian delegation statements hosted by the OSCE reported Rtut-BM complexes transferred toward Donetsk in November 2014 and a 1L262E Rtut-BM identified in northern Luhansk in April 2015.
Ukraine's NSDC reported Russian occupation-force combat use of Rtut-BM, and InformNapalm geolocated SPR-2M Rtut-BM imagery in Donetsk and occupied Luhansk Oblast.
Defense Express reported a Russian Rtut-BM captured by Ukrainian resistance fighters, while WarSpotting and Oryx document a Russian 1L262E Rtut-BM destroyed at Hostomel.

Rtut-BM sits inside a Russian electronic-warfare production chain rather than a single-factory identity. Official and specialist sources connect the modernized system to VNII Gradient design work, KRET/Rostec production, Kazan Optical and Mechanical Plant handover history, and Rosoboronexport's 1L262E export catalog designation.
Specialist and Rostec-linked sources use Rtut-BM, SPR-2M, and 1L262 for the modernized radio-fuze jammer branch.
Rosoboronexport lists the export system as 1L262E and describes it as a ground-force electronic-warfare station.
Rostec describes KRET production from 2011 and 2013 Russian Defense Ministry deliveries, while KOMZ records an August 2012 Rtut-BM handover milestone.
Rtut-BM is a protective electronic-warfare system rather than a strike weapon. Its main mission is to interfere with radio proximity fuzes on artillery rounds, mortar bombs, rockets, and similar munitions so they detonate at less damaging points or revert to contact-fuze behavior.
Rosoboronexport gives a coverage area of up to 50 hectares for the 1L262E station.
The same official description says the station can interfere with adversary forward-air-controller radio links.
The jammer is mounted on a lightly armored MT-LBu tracked chassis, allowing it to deploy with ground-force formations.
Rtut-BM is the modernized SPR-2M/1L262 branch of the earlier 1L29 Rtut-B / SPR-2 radio-fuze jammer family. Rosoboronexport catalogs the export system as 1L262E.
| Variant | Configuration | Designation notes |
|---|---|---|

| 1L262 Rtut-BM / SPR-2M | Russian-service modernized designation set | Rostec and specialist sources use Rtut-BM/SPR-2M for the modernized tracked system produced in the KRET/Rostec industrial network, while a 2024 Russian court record identifies a 1L262 (RB-321B) manufacture-and-supply contract.
