HQ: Vladivostok, Commander: Admiral Sergei Avakyants

Assessment

Identity

This record matches the Russian Navy’s Pacific Fleet headquarters in Vladivostok. The supplied commander field is outdated: Sergei Avakyants left the post in April 2023, and Russian state reporting identified Admiral Viktor Liina as Pacific Fleet commander by September 2024. ([govinfo.gov](https://www.govinfo.gov/content/pkg/GOVPUB-D5_200-PURL-gpo82226/pdf/GOVPUB-D5_200-PURL-gpo82226.pdf))

Basing

Open-source defense assessments place the fleet headquarters in Vladivostok, with most surface combatants and diesel submarines in the Vladivostok region and the nuclear submarine force, including SSBNs, centered on Petropavlovsk-Kamchatskiy. Russian MoD reporting in October 2024 said pier modernization at a Pacific Fleet base in Kamchatka had supported the introduction of seven nuclear submarines, including five Borey-class SSBNs and two Yasen-class boats. ([govinfo.gov](https://www.govinfo.gov/content/pkg/GOVPUB-D5_200-PURL-gpo82226/pdf/GOVPUB-D5_200-PURL-gpo82226.pdf))

Operational role

Chatham House describes the Pacific Fleet as the mainstay of Russia’s force in the Pacific Arctic and along the Far Eastern seaboard, with responsibility extending toward the Bering Sea, Bering Strait, Chukchi Sea approaches, and the Sea of Okhotsk. DIA likewise assesses the fleet as retaining strategic-strike capability and long-range deployment reach even though it lags the Northern Fleet in overall capability.

Vladivostok activity

Vladivostok functions as an operational command and logistics hub, not just an administrative headquarters. In August 2025 the fleet used the city as the command headquarters for the Russia-China Maritime Interaction exercise, then sent ships from Vladivostok on a joint patrol that covered more than 6,000 nautical miles; on March 11, 2026, TASS also reported a Pacific Fleet detachment already underway on an Asia-Pacific deployment after departing Vladivostok on February 12, 2026. ([tass.com](https://tass.com/defense/1995947))

Arctic placemarks

The Wrangel Island and Cape Schmidt placemarks correspond to real Russian Arctic military sites, but the sources reviewed do not publicly confirm them as organic Pacific Fleet tactical groups. In 2015, TASS reported construction of military-camp infrastructure, combat-duty positions, and life-support systems at both sites, plus restoration of the airfield at Cape Schmidt; later CSIS and Chatham House mapping continued to identify both locations as Russian Arctic military installations.
