1533rd Guards Anti-Aircraft Missile Regiment
Identification
Open sources strongly indicate this record refers to the Vladivostok-based 1533rd Guards Anti-Aircraft Missile Regiment, military unit 40083, under the 93rd Air Defence Division of the 11th Air and Air Defence Army. Public municipal and registry references also place unit 40083 in Vladivostok. ([tass.ru](https://tass.ru/armiya-i-opk/2693488))
Mission
The regiment's function is territorial air defence for Vladivostok and its military infrastructure. TASS reported in February 2016 that the regiment's Pantsir-S2 division entered combat duty "covering the sky of the main base of the Pacific Fleet," and TASS separately identifies Vladivostok as that fleet's main base. ([tass.ru](https://tass.ru/armiya-i-opk/2693488))
Equipment
Public reporting shows a modernization path from legacy long-range SAMs to newer systems: Pantsir-S2 entered the regiment in 2016; Russian state/media reporting in late 2017 indicated S-400 deployment for Vladivostok-area air defence; and IISS still listed the 1533rd SAM Regiment as an S-400 regiment in the Eastern Military District in its 2020 order-of-battle survey. I did not find a later high-confidence public source showing a different primary long-range system. ([tass.ru](https://tass.ru/armiya-i-opk/2693488))
Disposition
This should be read as a dispersed regimental site set rather than a single point facility. Local reporting says the former military town "Saman" near Vladivostok had housed the regiment's command element, while legacy veteran materials associate unit 40083 with additional firing positions on Russky Island and other Vladivostok approaches. Open sources reviewed do not publicly confirm which of the two supplied placemarks corresponds to which battalion as of March 12, 2026.

Confidence
The unit identification, city-level placement, and higher-echelon assignment are well supported. ([iiss.org](https://www.iiss.org/globalassets/media-library---content--migration/files/research-papers/iad-report.pdf)) Exact active-pad occupancy, current launcher counts, and whether both supplied coordinates remain live operational S-400/Pantsir positions are not publicly confirmed in the authoritative open sources reviewed here, so any more precise placemark-to-battalion assignment would be low-confidence.
