1st Air Defense Division
Identification
Open sources tie military unit 03123 to the 1st Air Defense Division in the Severomorsk garrison. A Russian Ministry of Defense legal list places v/ch 03123 in Severomorsk and separately places the division’s 331st Radio-Technical Regiment (v/ch 36138) in Shchukozero; derivative order-of-battle references for the 45th Air and Air Defense Army also list the 1st Air Defense Division as v/ch 03123 and the 1539th Separate Radio Relay Battalion as v/ch 03777 in Severomorsk. Using those sources together with the supplied coordinates/placemarks, this record most likely refers to a Shchukozero-area division command/support site associated with the 1st Air Defense Division rather than a standalone missile firing position.

Role
The division belongs to the Northern Fleet’s 45th Air and Air Defense Army, which was formed in December 2015 to strengthen air situation control in the Arctic. TASS reported in July 2018 that the army’s territorial control center entered combat duty with missions including control of Arctic airspace and protection of Russia’s air border within the Northern Fleet’s area of responsibility. That mission set is consistent with this site serving command, communications, and air-picture integration functions for regional air defense.

Subordinates
Open-source order-of-battle references list the 1st Air Defense Division as controlling the 531st Guards SAM Regiment at Polyarny, the 583rd SAM Regiment at Olenegorsk, the 1528th SAM Regiment at Severodvinsk, the 331st Radio-Technical Regiment at Shchukozero, the 332nd Radio-Technical Regiment at Arkhangelsk, the 223rd communications node, the 877th aviation guidance point, and the 1539th Separate Radio Relay Battalion. The same references describe the division as combining SAM, radar, guidance, and relay/communications elements, indicating a distributed air-defense network rather than a single-base formation; these unit and equipment details are from derivative OSINT-style references and should be treated accordingly.

Location
Shchukozero is part of the ZATO Severomorsk system and remains tied to Severomorsk by regular ground access; official regional transport materials list a Severomorsk–Shchukozero route, and municipal administration materials treat Shchukozero as part of the controlled-access Severomorsk area. Combined with the MoD listing of the 331st Radio-Technical Regiment in Shchukozero, this supports assessing the mapped compound as a rear-area radar/communications and command node embedded in the wider Severomorsk military complex.

Confidence
Public sourcing does not cleanly resolve the precise formal headquarters building for the division. Official/legal material usually gives only “Severomorsk” for v/ch 03123, while one order-of-battle reference places the 45th Army headquarters in Safonovo and the division in Severomorsk, and another encyclopedia-style entry places the division headquarters itself in Safonovo. The safest assessment is therefore: an identified 1st Air Defense Division-associated site in the Shchukozero sector of the Severomorsk garrison, with exact building-level functions not publicly confirmed.
