Open sources identify military unit 28036 as the 1489th Guards Anti-Aircraft Missile Regiment at the Vaganovo/Vaganovo-2 garrison in Vsevolozhsky District, Leningrad Oblast, east of St. Petersburg. RBC linked unit 28036 and the 1489th Regiment to Vaganovo; a local unit-anniversary notice and the local hospital’s feldsher point both place v/ch 28036 at Vaganovo-2/Vaganovo.

The site is part of the St. Petersburg air-defense ring. The regiment’s own local notice described it as a permanent-readiness unit protecting St. Petersburg’s air approaches, and CNA assessed the 1489th Regiment at Vaganovo as one of five regiments in the 2nd Air Defense Division, whose role is to guard St. Petersburg and neighboring areas. ([vsevvesti.ru](https://vsevvesti.ru/2013/11/01/%D0%BD%D0%B0-%D1%81%D1%82%D1%80%D0%B0%D0%B6%D0%B5-%D0%BC%D0%B8%D1%80%D0%BD%D0%BE%D0%B3%D0%BE-%D0%BD%D0%B5%D0%B1%D0%B0/))
Public order-of-battle sources place the regiment under the 2nd Air Defense Division and 6th Air and Air Defense Army. At district level, more recent public reporting points to the re-established Leningrad Military District; TASS reported in a March 2 dispatch that St. Petersburg authorities were coordinating with the Leningrad Military District and the 6th Air Force and Air Defense Army. I did not find open-source support for assigning this Vaganovo regiment to the Moscow Military District.

Open sources show a transition from older long-range SAMs to S-400 at this garrison. RBC still described the Vaganovo regiment as equipped with S-300 in March 2019; by August 2019, 47news, citing the Western Military District press service, said visitors would be shown the regiment’s S-400 systems. RUSI listed the unit with one S-400 battalion and a Pantsir element during Zapad-2017, while CNA’s 2021 assessment listed the 1489th Regiment at Vaganovo with two S-400 battalions.

This is a permanent garrison rather than a single field position. Yle’s 2022 satellite-imagery review described permanent headquarters and barracks for the St. Petersburg SAM regiments and noted equipment removal from the area around the 1489th Regiment headquarters near Vaganovo; it did not establish the regiment’s full remaining inventory. Public sources also confirm fixed support infrastructure: the local hospital runs a feldsher point at v/ch 28036, and an August 2025 public procurement listing referenced major water-network repairs at v/ch 28036, military town 25, in Vaganovo. Public reporting confirms dispersed firing positions several kilometers from regiment HQ, but I could not independently match each supplied placemark to a named battery position from open sources.
