333rd Radio-Technical Regiment
Identification
Open sources support identifying this record as Russian military unit 17646, the 333rd Radio-Technical Regiment, headquartered in the Hvoyny territorial zone of Krasnoye Selo, St. Petersburg. A 2009 Ministry of Defense order lists v/ch 17646 at "198327, Saint Petersburg, Krasnoselskiy district, pos. Hvoyny," and registry-derived mirrors later keep the unit at Hvoyny, 36.

Command linkage
The same 2009 MoD order also lists v/ch 10953 at Hvoyny under the 1st Command of the Air Force and Air Defense, showing that 17646 sat inside a larger air-defense garrison. Recent open-source order-of-battle references consistently place the 333rd regiment under the 2nd Air Defense Division / 6th Air and Air Defense Army; that is consistent with the supplied hierarchy, but I did not locate a current primary MoD page naming the regiment’s 2026 chain directly.

Dispersed footprint
Public administrative records indicate that the regiment is not confined to one barracks site in Hvoyny. A regional power-sector regulation names separate MoD consumers "v/ch 17646-M" on the Smuravyevo substation and "v/ch 17646-T" as a distinct military town, while a March 2025 local election notice places "v/ch 17646-V" in the Vaganovo-2 military town. The verified takeaway is a dispersed regimental network with detached sites; the exact function of each letter-suffix location is not publicly confirmed in the sources reviewed.

Lineage
Historical secondary sources trace the unit to the 46th Radio-Technical Brigade at Hvoyny, reorganized into the 333rd Radio-Technical Regiment in 2009. The same commemorative reporting says the regiment received its Battle Banner on 30 December 2011. I did not find a primary MoD history page confirming those lineage details, so they should be treated as corroborated secondary reporting rather than official confirmation.

Current status
Registry mirrors say the legal entity "Voyskovaya Chast 17646" was removed from EGRUL on 10 December 2020, but official/local public materials continued to reference an active v/ch 17646 in Hvoyny in 2023-2025. Those references include a school-district report describing field training at the "acting military unit 17646" and a district education program naming the 333rd regiment as an ongoing partner. The most likely reading is an administrative/legal bookkeeping change rather than open-source evidence that the regiment’s Hvoyny site closed.
