Coastal Troops of the Pacific Fleet

INTELLIGENCE BRIEFRF FORCES

Site identity

This record is best understood as the Russian Pacific Fleet’s coastal-troops grouping, not a single installation. Public sources tie that grouping to a Primorye-based naval infantry formation formerly known as the 155th Guards Naval Infantry Brigade, redesignated as the 55th Guards Naval Infantry Division on 1 December 2025, and to the Kamchatka-based 40th Guards Naval Infantry Brigade; the dataset’s continued use of the 155th brigade label appears to lag that redesignation.

Primorye cluster

One major cluster is in Primorye. The former 155th brigade, now the 55th division, is publicly reported training in Primorye, and open reporting places a 72nd coastal-missile formation at Smolyaninovo; public reporting is inconsistent on whether that 72nd BRAV formation is described as a brigade or a regiment. TASS has also identified a Podsolnukh over-the-horizon radar deployed in Primorye for maritime and air surveillance. ([tass.ru](https://tass.ru/armiya-i-opk/25992739?utm_source=openai))

Kamchatka cluster

A second major cluster is on Kamchatka. The 40th Guards Naval Infantry Brigade is a Kamchatka formation, and 2024-2025 Pacific Fleet exercise reporting described Bal and Bastion coastal-missile crews on Kamchatka and the Kurils rehearsing anti-landing strikes and joint actions with Pacific Fleet marines, which is consistent with a substantial Kamchatka-based coastal-missile component in this record.

Mission and posture

Verified public reporting points to a coastal-defense mission set centered on defending Pacific Fleet bases and approaches, protecting maritime communications, and defeating amphibious landings on Kamchatka and the Kurils. Taken together, the coastal-missile deployments and Primorye radar reporting indicate an observation-and-strike architecture along the Sea of Japan and Sea of Okhotsk approaches, rather than a purely administrative headquarters.

Operational use and gaps

These forces are not confined to local garrison defense. Russian official statements in 2025 named both the 155th and 40th Pacific Fleet marine formations among units fighting in Kursk, and Gudkov’s March 2025 promotion from command of the Pacific Fleet’s 155th brigade to Navy deputy commander underscores the combat prominence of this formation. By contrast, I did not locate equally authoritative public confirmation for every support placemark in the dataset, including the named EW, communications, reconnaissance, and arsenal sites, so those subordinate points should be treated as only partially verified in open sources.
