81st Radio-Technical Regiment
Identification
Open sources strongly support identifying this record as the 81st Radio-Technical Regiment (v/ch 49289) of the Baltic Fleet, headquartered in Pereslavskoye, Zelenogradsk district, Kaliningrad Oblast. OSW order-of-battle references list the 81st Radio-Engineering Regiment at Pereslavskoye, and Russian court records repeatedly give v/ch 49289’s address as Pereslavskoye.

Command role
The regiment is publicly associated with the Baltic Fleet’s 44th Air Defense Division. Russian and analytical reporting describe that division as including the 183rd and 1545th surface-to-air missile regiments plus the 81st radio-technical regiment, indicating the regiment’s role is air-surveillance and target-information support within Kaliningrad’s integrated air-defense network.

Verified footprint
A fixed communications/radar-support element is documented at the Pereslavskoye site: 2022 appellate rulings describe leased property at v/ch 49289 in Pereslavskoye used for an antenna-mast structure and equipment. Additional public records tie v/ch 49289 to military-town footprints at Velikolukskoye, Gvardeyskoye in Bagrationovsk district, and Barsukovka near Neman, indicating a dispersed regimental presence across Kaliningrad Oblast; however, open sources do not publicly confirm the exact function of each detached site, so not every supplied placemark can be matched with high confidence.

Operational indicators
As of April and November 2023, Baltic Fleet press-service reporting carried by TASS and Interfax said the regiment’s radio-technical subunits were training with Nebo and Gamma radar stations and automation complexes, moving to field positions, camouflaging sites, assuming combat duty, conducting radiolocation reconnaissance, and passing tracks to S-400-equipped missile units. The November 2023 reporting cited about 300 personnel and more than 50 pieces of equipment, which is consistent with a field-deployable surveillance regiment rather than a purely static installation.

Geographic relevance
The Pereslavskoye-centered regiment sits inside Russia’s Kaliningrad exclave between Poland, Lithuania, and Baltic Sea approaches. Because verified reporting links it to radar surveillance and data handoff to S-400 units of the 44th Air Defense Division, the site’s main military significance is early warning and air-picture generation for Baltic Fleet air defense, not strike operations.
