The yard sat in Petrozavodsk, Republic of Karelia, on Lake Onega, with inland-waterway access toward the White, Baltic, Caspian, and Black Sea routes. Sudostroenie.info described the OAO Avangard shipyard as active in military and civil shipbuilding, ship repair, heat generation, and repair or modernization of rail equipment, with its own quay and portal cranes.
For defense catalog purposes, Avangard is most important as a mine-warfare producer and repair yard. RussianShips.info lists Avangard Shipyard, Petrozavodsk as the construction site for dozens of Project 1265 hulls, including the Project 1265E export sequence. Korabel.ru also reported in 2005 that Avangard had repaired Project 1265-type base minesweepers for Russia's Ministry of Defence and cited the yard's long history of minesweeper production, including exported vessels.

Avangard is a historical Petrozavodsk shipyard lineage rather than a clearly active defense prime with a current official website. Public sources are strongest for its Soviet/Russian name history, Petrozavodsk facility, Project 1265 mine-countermeasure construction, and post-Soviet minesweeper repair reporting; the website field points to an industry-directory profile because no current official yard site was identified.
