Profile summary

Assessment

Identity

This record is best understood as a distributed Russian Aerospace Forces / radio-technical radar network rather than a single base. The strongest direct open-source matches are the Sopka-2 site on Wrangel Island, which Russian reporting said entered service in 2016, and the Rezonans-NE complex at Indiga in Nenets Autonomous Okrug, visible in publicly discussed imagery dated January 30, 2026; public reporting also places related Rezonans-N sites at Cape Kanin/Shoina and Rogachevo on Novaya Zemlya.

Radar mix

The equipment names associated with this record fit a layered surveillance architecture. Official Rosoboronexport material describes Nebo-SVU as a VHF radar for detection and tracking of modern low-signature targets; Rezonans-NE as a long-range VHF radar for all-altitude detection of stealth, ballistic and hypersonic targets; and Podlet-K1KE as an S-band low-altitude detector. Almaz-Antey/LEMZ describes Sopka-2 as a 3D air-route radar, including a transportable version intended to reuse older P-35/P-37 radar positions with minimal site preparation.

Arctic belt

Russia publicly stated in 2015 and again in 2018-2019 that it was building out air-defense radar infrastructure on Wrangel Island, Sredniy Island and Cape Schmidt. Independent Arctic reporting says the first two Rezonans-N sites at Cape Kanin and Indiga were operating from 2017, with Rogachevo added in 2019 and additional Kola Peninsula sites later. That pattern matches an Arctic-oriented early-warning belt rather than isolated local radars. ([tass.com](https://tass.com/defense/842201?utm_source=openai))

Operational role

As of December 14, 2020, the chief of Russia’s Radio-Technical Troops said Arctic and eastern sectors were on combat duty with Fundament-M automation and radars such as Nebo, Podlyot, Kasta-2-2 and Sopka. On January 6, 2025, Russia’s Defense Ministry said radio-technical troops had tracked more than two million aerial objects during 2024. Taken together, this record is most plausibly a map of sensor nodes feeding Russia’s wider air-defense picture, not a list of autonomous missile batteries.

Confidence limits

Open sources reviewed here verify the network concept and several specific Arctic nodes, but they do not provide equally direct confirmation for every placemark in the 21-point record or each site’s current equipment fit. Outside the best-documented Arctic examples, site-by-site status should therefore be treated as only partially verified; exact unit identities, readiness levels, and any recent removals are not publicly confirmed. This is an analytic judgment based on the source set reviewed.
