3rd Air Defense Division
Identified formation
Open sources identify this record as Russia’s Arctic-focused 3rd Air Defense Division, announced on 28 February 2020 as a newly formed air-defense division in the Arctic and later described in reporting on the 45th Air and Air Defense Army. ([tass.ru](https://tass.ru/armiya-i-opk/7859469?utm_source=openai)) A 2021 report on the division’s build-out placed its fielded elements on Novaya Zemlya and at Tiksi in Yakutia, which is consistent with the supplied placemarks.

Mission
Russian official statements describe the formation’s role as strengthening control of Arctic airspace and protecting the Northern Sea Route. ([tass.ru](https://tass.ru/armiya-i-opk/7859469?utm_source=openai)) In practice, the verified sites tied to this division sit at opposite ends of Russia’s central Arctic littoral: Rogachevo on Novaya Zemlya and Tiksi on the Laptev Sea coast.

Novaya Zemlya element
The western placemark matches the Rogachevo/Novaya Zemlya air-defense site. TASS reported that a Northern Fleet air-defense regiment on Novaya Zemlya entered combat duty for protection of Arctic airspace in 2015, and later reporting stated that S-400 systems were placed on combat duty there and linked the regiment to Rogachevo airfield. ([tass.ru](https://tass.ru/armiya-i-opk/7367603?utm_source=openai)) This supports the identification of the Rogachevo placemark as a confirmed component of the division’s Arctic air-defense network.

Tiksi element
The eastern placemarks align with the Tiksi/Tiksi-3 garrison in the Sakha Republic. Official Russian reporting stated that units of the new air-defense formation began experimental combat duty in Tiksi to secure airspace over the Northern Sea Route, and in March 2020 the Northern Fleet commissioned a modular dormitory and dining facility for the new anti-aircraft missile regiment there. ([tass.ru](https://tass.ru/armiya-i-opk/7295975?utm_source=openai)) TASS also reported Arctic air-defense exercises by Northern Fleet air-defense units based in Tiksi in 2023, indicating continued site activity after the initial deployment phase.

Command caveats
The exact headquarters location of the 3rd Air Defense Division is not publicly clear in the sources reviewed; one think-tank review explicitly said the new division’s headquarters were unclear, and no authoritative public source found here resolved the Tiksi "HQ (?)" placemark. ([gfsis.org.ge](https://gfsis.org.ge/files/library/pdf/English-2713.pdf?utm_source=openai)) The supplied hierarchy is consistent with reporting up to 2024, but TASS reported in December 2023 that the 45th Air and Air Defense Army would transfer to the Leningrad Military District, and a 2025 TASS Northern Fleet dossier states the fleet’s former military-district territory entered the LMD on 1 March 2024; the division’s exact higher-command presentation as of 2026 is therefore not fully resolved in the open sources reviewed.
