332nd Radio-Technical Regiment
Unit Identification and Designations
The 332nd Radio-Technical Regiment is a formation of the Russian Aerospace Forces’ Radio-Technical Troops. Its military unit identifier is 21514 for the headquarters. Subordinate elements use the same numeric identifier with letter suffixes, including 21514-A, 21514-E, 21514-L, 21514-V, 21514-G, 21514-D, 21514-Zh, 21514-K, and 21514-I. The provided information specifies that subunit 21514-G operates a Rezonans-N radar. The headquarters is identified as military unit 21514.
Mission and Subordination
Radio-Technical Troops are responsible for continuous airspace surveillance, early warning, formation of the recognized air picture, and provision of target designation to air-defense missile units and fighter aviation. Open-source reporting places the 332nd Radio-Technical Regiment within the air-defense structure covering Russia’s Arctic and northwestern approaches, under the Russian Aerospace Forces aligned to the Northern Fleet’s air and air-defense grouping. Its outputs feed regional air-defense command posts for engagement by surface-to-air missile regiments and fighter interceptors.
Subunit Structure and Disposition
The letter-suffixed subunits listed (A, E, L, V, G, D, Zh, K, I) indicate separate detachments or companies operating radar posts under the regimental headquarters (21514). This naming convention is standard for Russian military unit numbering, where geographically dispersed elements retain the parent unit number with a letter suffix. The list implies at least nine subordinate posts in addition to the headquarters. Exact geolocations and the functional profile of each suffix-coded detachment are not publicly disclosed in the provided material.
Known Specialized Asset: Rezonans-N (Subunit 21514-G)
The Rezonans-N is a stationary, meter-band (VHF) phased-array radar designed for long-range early warning and detection of aerodynamic and ballistic targets, with a claimed emphasis on detecting low-observable aircraft. It uses multiple fixed array faces to provide 360-degree coverage without mechanical rotation. Manufacturer claims cite very long detection ranges and high-altitude coverage; these figures are promotional and not independently verified in open sources. Rezonans-N is not a fire-control radar; it contributes cueing-quality data to higher-echelon command-and-control systems that task engagement assets. Its deployment in a subunit of the 332nd Regiment aligns with Russia’s broader effort to strengthen Arctic early warning.
Radar and Sensor Suite (General Context)
Radio-Technical Troops regiments typically field a mixed sensor network to provide layered coverage, often including modern three-dimensional radars such as Nebo-M (55Zh6M), Gamma-family systems, 96L6-series, 59N6 Protivnik-series, and low-altitude radars like Podlet-K1, along with legacy meter-band sets (e.g., P-18 derivatives). The exact allocation of specific radar models to the 332nd Regiment’s individual subunits has not been publicly confirmed. Sensor diversity enables coverage of different altitude bands, mitigation of electronic countermeasures, and enhancement of detection against low-RCS targets.
Operational Geography and Coverage
The regiment’s area of responsibility is associated in open sources with high-latitude sectors of the Russian northwest and Arctic approaches, including airspace over and adjacent to the Barents and Kara Seas. Rezonans-N deployments publicly reported in recent years are in Murmansk and Arkhangelsk regions and on Arctic archipelagos, consistent with the mission to surveil northern air and maritime axes. The distributed subunit structure is intended to create overlapping radar fields that reduce coverage gaps in polar conditions.
Command, Control, and Data Integration
Radar data from regimental posts are fused at regimental and higher-echelon command posts using automated air-defense control systems and are disseminated to regional air-defense networks. The resulting recognized air picture supports engagement by surface-to-air missile units (e.g., S-300 and S-400 families) and vectoring of fighter aviation. Rezonans-N contributes early-warning cues that can be correlated with other band radars for improved track quality. Specific internal system architectures and data-link configurations for the 332nd Regiment are not publicly disclosed.
Infrastructure and Logistics
Subunits operating in Arctic and sub-Arctic conditions typically rely on dedicated power generation, weatherized shelters for electronics, satellite and troposcatter communications, and seasonal ground or air resupply. Fixed installations like Rezonans-N are built on prepared sites with multiple static array structures and equipment shelters. Harsh climate, limited transport windows, and long supply lines drive a premium on reliability, modularity, and remote maintenance capabilities.
Operational Considerations and Vulnerabilities
Arctic radar operations must contend with extreme temperatures, icing, auroral phenomena affecting propagation, and limited daylight seasons. To mitigate electronic warfare threats and environmental effects, Russian air-defense networks layer sensors across frequency bands and employ frequency agility and networked data fusion. Fixed long-range radars such as Rezonans-N offer persistent coverage but present predictable target sets if adversaries possess standoff suppression capabilities, which is offset in part by hardening, dispersion across multiple posts, and redundancy.
Status and Recent Developments (Open-Source Context)
Public reporting from 2019 to 2022 described the commissioning of multiple Rezonans-N sites in Russia’s Arctic regions and continued modernization of Radio-Technical Troops assets. As of 2024–2025, the Russian Aerospace Forces continue prioritizing high-latitude early warning and air-defense integration, consistent with the presence of a Rezonans-N-equipped subunit within the regiment. Specific readiness levels, manning, and equipment distribution within the 332nd Regiment are not published in open sources.
Information Gaps and Classification Notes
Confirmed details from the provided information include the regiment’s designation (332nd Radio-Technical Regiment), its headquarters identifier (military unit 21514), the list of suffix-coded subordinate elements (A, E, L, V, G, D, Zh, K, I), and the presence of a Rezonans-N radar with subunit 21514-G. Exact locations, personnel strength, detailed equipment lists for each subunit, internal communications architecture, and current operational status are not publicly available or are classified; these specifics cannot be provided.
