Bolshevik Plant

Bolshevik Plant was the Soviet-era name of the Obukhov industrial complex in Saint Petersburg, a long-running artillery, metallurgy, and heavy machine-building producer whose earlier Obukhov identity was restored after the Soviet period. Public sources connect the plant's 1922-1992 Bolshevik name to the present Obukhov/Almaz-Antey legal and industrial lineage.

Bolshevik Plant is the Soviet-era name used from 1922 to 1992 for the Obukhov industrial complex in Saint Petersburg. The plant was founded in 1863 with Maritime Ministry backing and built its reputation on steelmaking, artillery, naval guns, ammunition, and heavy machine-building work.

Modern public references usually use Obukhov Plant or Obukhov State Plant. The older Bolshevik name remains relevant for Soviet artillery records because sources identify the Leningrad plant with the B-series artillery design index and with production of the 203 mm B-4 heavy howitzer alongside other Soviet factories.

The current Obukhov legal entity is part of Almaz-Antey and is described in public records as a diversified machine-building enterprise involved in mechanical, hydraulic, hydromechanical, and electromechanical equipment, including missile-system and launcher-related production. That modern context helps separate the historical Bolshevik artillery name from the plant's later air-defense and missile-industrial role.
