25th Air Defense Division
Identification
Official municipal records from June 2025 list the commander of military unit 54912 as chief of the Komsomolsk-on-Amur local garrison. Official CSKA reporting from 2020-2023 repeatedly identifies military unit 54912 as the 25th Air Defense Division, supporting identification of this record as the division’s headquarters element in Komsomolsk-on-Amur.

Command chain
Public order-of-battle references place the 25th Air Defense Division under the 11th Army Air Force and Air Defense, headquartered at Khabarovsk. Interfax-Russia reported that the 11th Air Force and Air Defense Army was formed in the Eastern Military District in August 2015.

Regional posture
Official reporting shows continued modernization of air-defense forces in Khabarovsk Krai. TASS reported in July 2018 that an Eastern Military District air-defense formation in the krai was receiving S-400 systems, and in August 2020 named the 1529th Guards Surface-to-Air Missile Regiment in Khabarovsk as receiving an S-400 regimental set. Public order-of-battle references associate that regiment with the Komsomolsk-based 25th division. ([tass.ru](https://tass.ru/armiya-i-opk/5400445/amp))
Strategic setting
Komsomolsk-on-Amur is a major aerospace-production node. TASS reported in May 2024 and February 2025 that the Gagarin aircraft plant there was delivering new Su-35S fighters and had reached a production pace sufficient to meet growing Su-57 demand. The division HQ’s placement in the same city therefore aligns with protection of a high-value defense-industrial center; that linkage is an analytic inference from the site’s location and the city’s industrial role.

Local role
By June 2025, city authorities included the commander of military unit 54912 in municipal security and coordination bodies in the capacity of chief of the Komsomolsk-on-Amur local garrison. This indicates a standing command-and-coordination role in the city in addition to purely field air-defense functions.
