Plant No. 4 named after Voroshilov, Krasnoyarsk

Plant No. 4 named after Voroshilov, Krasnoyarsk was the wartime and early postwar Krasmash state-defense identity tied to Soviet automatic anti-aircraft artillery production, including the AZP-57 gun of the S-60 system.

2 weapons

The Plant No. 4 name refers to a Soviet state arms plant identity used at Krasnoyarsk after wartime evacuation and consolidation. Krasmash's own history records the enterprise under the People's Commissariat of Armaments, with the name Plant No. 4 named after K. E. Voroshilov from November 1942 to March 1948 before later Krasnoyarsk Machine-Building Plant identities.

For this catalog, the key connection is anti-aircraft artillery. The National Defence University of Ukraine identifies Plant No. 4 named after Voroshilov in Krasnoyarsk as the 1950 serial-production site for the 57 mm AZP-57 gun used in the S-60 system, while Krasmash's history describes wartime production of 61-K guns, mortars, aerial bombs, and naval mines.

This profile covers a historical Soviet state-plant name rather than a standalone contemporary company. The current Krasmash website is used for official continuity and validation because the Plant No. 4 named after Voroshilov identity is documented as a former Krasnoyarsk Machine-Building Plant name, not as an active entity with its own website. Headquarters map coordinates are intentionally omitted.
