340th Radio-Technical Regiment
Identity
The location that is consistently corroborated in open sources is the 340th Radio-Technical Regiment home station at Mirny, Krasnoyarsky District, Samara Oblast, under military unit number 40278. The Krasnoyarsky district administration reported voting by unit 40278 personnel in Mirny in June 2020, and the district culture administration reported a 15 December 2025 ceremony in Mirny for the 74th anniversary of the radio-technical troops led by the commander of the 340th regiment, Col. Aleksey V. Simikin. ([kryaradm.ru](https://kryaradm.ru/novosti/novosti-rajona/voinskaya-chast-40278-p-mirnyj-progolosovala-po-popravkam-v-konstitutsiyu))
Command
An official CSKA/Samara article identifies the 340th Radio-Technical Regiment as part of the 76th Air Defense Division of the 14th Air and Air Defense Army, Central Military District. Open reporting on radiotechnical regiments in this air-defense system shows receipt of radar assets such as P-18RT/Terek, PRV-13P and Nebo-U elsewhere in the district, but the exact radar inventory assigned specifically to unit 40278 at Mirny is not publicly confirmed in the sources reviewed.

Footprint
Official documents indicate that the regiment or administratively linked subelements are geographically dispersed beyond Mirny. A Perm Krai ombudsman report listed 40278/12 at Suyankovo; a Central Military District order listed 40278-15 as a separate communications company in Shadrinsk, Kurgan Oblast; and an official 2025 Tyumen district electoral publication listed 40278-16 in Gorkovka. This supports a distributed support/radar network across the wider Volga-Ural area, although public sources do not fully describe the current structure of all numbered detachments.

Infrastructure
Mirny has at least some active training/support infrastructure. In a CSKA report on a 76th Air Defense Division shooting championship, AK firing was conducted at the range in unit settlement Mirny, and unit 40278 placed second overall; this indicates a functioning garrison and divisional training role at the Mirny site at the time of reporting.

Confidence
The Mirny garrison is the only location in this record that is strongly verified as the regiment’s principal identifiable site. The supplied placemark set appears only partially corroborated: official sources do confirm some outlying numbered elements, but they do not validate the full 17-coordinate set, and at least some official suffix-to-location references do not align with the supplied coordinates. For analytic use, treat this record as the Mirny-based regiment with partially verified detached elements rather than a fully confirmed list of exact subordinate site coordinates.
