1545th Guards Anti-Aircraft Missile Regiment
Identification
Open sources support identifying this record as the Kaliningrad-based 1545th Anti-Aircraft Missile Regiment, historically tied to military unit 01907 and traced by specialist order-of-battle research to the 43rd Anti-Aircraft Missile Brigade at Znamensk, redesignated in 2009. CNA and Russian press reporting place the regiment in the 44th Air Defence Division with the 183rd Air Defence Regiment and the 81st Radio-Technical Regiment. In the sources reviewed for the Kaliningrad site, the unit is named simply as the 1545th Anti-Aircraft Missile Regiment; the "Guards" honorific in the hierarchy path was not independently corroborated here.

Verified siting
The best-corroborated current operating area is north of Gvardeysk, near Kruglovka/Kruglovo. A Russian MoD media announcement and Interfax said the new Kaliningrad S-400 regimental set would assume combat duty there on 15 March 2019, and CNA later assessed the 1545th's two S-400 battalions as stationed just north of Gvardeysk. Kruglovka itself is a village about 5 km north of Gvardeysk. ([forsmi.ru](https://www.forsmi.ru/announce/373695/))
Equipment
The formation's open-source equipment history runs from Krug to Buk-M1 and then S-300V-series systems. By early March 2019 it had been rearmed with an S-400 regimental set; CNA assessed the conversion as indicating the regiment's earlier S-300V system was no longer present in the oblast.

Placemark confidence
The western S-400-associated placemark in the supplied data fits the Kruglovka/Kruglovo area well, but the two eastern placemarks labeled S-300PS are not corroborated as 1545th positions in the reviewed sources. CNA instead attributes the division's S-300PS battalions near Chernyakhovsk air base to the 183rd Air Defence Regiment, so those eastern sites should be treated as unverified or possibly misattributed for this regiment.

Command status
Historically, the regiment sat under the Baltic Fleet's 44th Air Defence Division, and Russian reporting in 2018-2024 continued to describe Kaliningrad S-400 activity as part of the Baltic Fleet's air-defense formation. However, on 26 June 2024 TASS reported, citing a source and explicitly noting the lack of official confirmation, that the 44th Air Defence Division had been transferred to the 6th Army of Air and Air Defence. The regiment's current administrative subordination is therefore publicly inconsistent in open sources.
