This record most likely corresponds to the Russian 589th Anti-Aircraft Missile Regiment, military unit 83266, in the Nakhodka–Zolotaya Dolina area of Primorsky Krai. Open sources place the 589th in Nakhodka within the 93rd Air Defense Division, while public registry and municipal records tie unit 83266 specifically to s. Zolotaya Dolina.

Two of the supplied placemark areas align almost exactly with historical SAM positions published for the regiment’s predecessor formation: 42°44′10″N 132°51′38″E matches the southern site, and 42°57′03″N 133°06′20″E matches the northern site. That is strong open-source confirmation that those points are long-standing missile battalion positions associated with the 589th. ([ww2.dk](https://www.ww2.dk/new/pvo/sam/88zrbr.htm))
Official Russian reporting said an S-400 regimental set was allocated to Nakhodka in June 2012, and reported in August 2012 that the fourth S-400 regiment entered combat duty there. A 2019 Russian defense analysis likewise described the 589th at Nakhodka as a two-battalion S-400 regiment. I did not find equally authoritative public confirmation in this review for any additional point-defense system at this exact site. ([ria.ru](https://ria.ru/20120609/669500221.html))
The northern cluster sits adjacent to the former Zolotaya Dolina military airfield northeast of Nakhodka. Open sources list the airfield as disused since 1998, while current municipal records still show unit 83266 maintaining facilities in the village; the local school reported leasing a sports hall from the unit as of September 16, 2025. Public sources reviewed here support a Zolotaya Dolina administrative presence, but not the exact current HQ building inside the cluster. ([ru.wikipedia.org](https://ru.wikipedia.org/wiki/%D0%97%D0%BE%D0%BB%D0%BE%D1%82%D0%B0%D1%8F_%D0%94%D0%BE%D0%BB%D0%B8%D0%BD%D0%B0_%28%D0%B0%D1%8D%D1%80%D0%BE%D0%B4%D1%80%D0%BE%D0%BC%29))
Assessed function is area air defense for the Nakhodka sector of southern Primorye. The regiment’s documented combat duty in Nakhodka, its dispersed positions around Nakhodka and Zolotaya Dolina, and the presence of major port infrastructure in Nakhodka together indicate a role in covering coastal and port approaches on the Sea of Japan. This mission statement is an inference from location and role, not a direct official unit description. ([ria.ru](https://ria.ru/20120815/724086797.html))
