49th Radio-Technical Brigade
Unit Identification and Role
The 49th Radio-Technical Brigade (military unit 39872) and the 2289th Separate Radio-Technical Battalion (military unit 25888) are elements of the Radio-Technical Troops of the Russian Aerospace Forces (VKS). Radio-Technical Troops operate ground-based radar and associated systems to conduct continuous airspace surveillance, early warning, target detection and tracking, identification, and dissemination of the recognized air picture to air-defense and aviation command posts. The 49th Brigade is a brigade-level formation; the 2289th is a battalion-level formation within this branch. The 49th brigade headquarters is identified with the same administrative number (v/ch 39872), consistent with Russian practice of assigning the military unit number to the HQ element.
Administrative Identifiers (v/ch Numbers)
The notation “military unit” (Russian: v/ch, voinskaya chast) is an administrative identifier used by the Russian Ministry of Defense. The identifiers in question are 39872 for the 49th Radio-Technical Brigade and 25888 for the 2289th Separate Radio-Technical Battalion. These identifiers can persist across reorganizations, but they may be reassigned when units are restructured. Official, authoritative crosswalks between v/ch numbers and exact addresses are not publicly maintained, and as of October 2024 no publicly released Ministry of Defense document provides a detailed, authoritative roster of current addresses for these specific numbers.
Headquarters Site (49th Radio-Technical Brigade, v/ch 39872)
The brigade headquarters functions as the command-and-control hub, aggregating radar data from subordinate battalions and adjacent formations, maintaining 24/7 operational duty, and coordinating with air-defense divisions and aviation command posts. Typical HQ infrastructure includes a hardened or semi-hardened operations center with automated air-defense control systems, secure communications nodes, equipment depots and maintenance workshops, barracks and administrative facilities, a motor pool for support and command vehicles, and redundancy such as backup power generation and alternate control rooms. Precise garrison location details for v/ch 39872 are not published in official open sources.
2289th Separate Radio-Technical Battalion (v/ch 25888)
The 2289th Separate Radio-Technical Battalion operates assigned radar sites and remote posts, deploys and maintains mobile radar assets, and ensures local communications and power support for continuous radar coverage. Open sources associate the administrative number 25888 with the 2289th battalion. An official Ministry of Defense publication explicitly confirming the battalion’s parent formation has not been located in the public domain as of October 2024; consequently, while the unit clearly belongs to the Radio-Technical Troops, its definitive command relationship to the 49th Brigade cannot be stated without reservation.
Mission and Tasks
Radio-technical formations provide round-the-clock monitoring of national airspace, detect and track aerodynamic and ballistic targets, perform identification friend-or-foe procedures, and form the recognized air picture for air-defense and aviation commands. They support air-defense missile units (e.g., S-300 and S-400 formations) by providing surveillance and target designation data, enable early warning for command authorities, and contribute to flight safety for state aviation when tasked. The brigade echelon is responsible for integrating coverage across its sector, ensuring redundancy, and coordinating mobility and reconstitution after simulated or actual strikes or electronic attack.
Infrastructure and Deployment Pattern
Radio-technical brigades maintain a mixed network of fixed radar nodes and mobile positions. Fixed sites are typically located on elevated terrain and may include permanent towers or mast systems, hardened shelters for equipment, and protected communications nodes. Mobile elements use transportable radars and support vehicles, deployable masts (e.g., 40V6-series), diesel power modules, and climate-controlled shelters. Standard site features include perimeter security, radar pads, instrumented test and calibration facilities, fuel storage for generators, and dedicated fiber, microwave, or troposcatter communications to higher command posts. Remote posts are often staffed on a rotational basis to maintain continuous surveillance.
Radar and Sensor Capabilities
Across the Radio-Technical Troops, widely reported systems include Nebo-M (55Zh6M) and Nebo-UM (55Zh6UM) for multi-band three-dimensional surveillance, Protivnik-G (59N6) for long-range three-dimensional coverage, Podlet-K1 (48Ya6-K1) for low-altitude detection, the 96L6 series three-dimensional surveillance radars often employed with S-300/400 formations, modernized P-18-2 VHF stations, and legacy long-range VHF sets such as 5N84A (P-14), supplemented in some locations by 76N6 low-altitude detection radars. Manufacturer-stated performance for Protivnik-G is commonly cited up to roughly 450 km, for Podlet-K1 up to roughly 300 km (optimized for low-altitude targets), and Nebo-M is credited with extended ranges for aerodynamic and certain ballistic targets. Specific radar inventories for v/ch 39872 and v/ch 25888 have not been officially published.
Command, Control, and Data Integration
Automated control and data fusion underpin brigade operations. Systems such as Baikal-1M/1ME at air-defense command posts and the Fundament-M family of support modules are widely documented in Russian service to integrate radar inputs and disseminate the recognized air picture to air-defense brigades and aviation command centers. Brigade headquarters merge radar data from subordinate battalions and adjacent units, execute identification procedures, correlate and filter tracks, and forward engagement-quality data over secure digital links. This framework enables coordination with surface-to-air missile regiments and fighter aviation for air-defense operations.
Operational Activity and Training
Radio-technical brigades and battalions conduct continuous combat duty, periodic unannounced readiness checks, and participate in strategic-operational exercises organized by their Military Districts (e.g., Kavkaz, Zapad, Tsentr, Vostok in various years). Core training tasks include rapid deployment and emplacement of mobile radars, restoration of coverage after simulated kinetic or electronic attack, frequency management and deconfliction, interoperability with air-defense missile units and aviation, and validation of automated control systems following equipment upgrades. Public reporting regularly notes deliveries of new radars being followed by integration and crew certification events.
Modernization Status (2015–2024)
Following the August 2015 creation of the Aerospace Forces (VKS) through the merger of the Air Force and Aerospace Defense Troops, the Radio-Technical Troops have undergone staged modernization. Ministry of Defense communiqués from 2018 through 2024 emphasize fielding of Nebo-M/UM, Podlet-K1, Protivnik-G, and 96L6-series radars; upgrades to automated control systems; and commissioning or refurbishment of fixed radar sites. These measures aim to improve detection of low-RCS targets such as cruise missiles and unmanned aerial systems, extend high-altitude and long-range coverage, and enhance resilience through mobility, redundancy, and digital data fusion.
Command Relationships and Doctrinal Context
Radio-technical brigades are assigned to Air and Air Defense Armies within the VKS and coordinate closely with air-defense divisions and corps-level formations. Their missions are codified in Russian doctrine to include continuous monitoring of national airspace, support to air-defense operations, and provision of radar data to state aviation authorities when directed. The designation of the 49th Radio-Technical Brigade (v/ch 39872) and the identification of the 2289th Separate Radio-Technical Battalion (v/ch 25888) are consistent with established organizational patterns of the Radio-Technical Troops.
Information Gaps and Classification Constraints
Exact garrison locations, internal manning levels, detailed equipment holdings, and the full list of subordinate elements for the 49th Radio-Technical Brigade (v/ch 39872) and the 2289th Separate Radio-Technical Battalion (v/ch 25888) are not disclosed in authoritative public sources and may be classified. Open-source references exist but are inconsistent and may reflect historical dispositions that changed during reforms and reorganizations. In the absence of official publication, further specificity on precise locations or sensitive operational details cannot be provided.
