Plant No. 4 Perm Weapon Systems
Plant No. 4 Perm is a Soviet-era numbered factory attribution used in open references for the 100 mm KS-19 anti-aircraft gun, connecting this builder archive to Cold War heavy anti-aircraft artillery production.
1 weapon systemsOpen sources identify Plant No. 4 Perm as the manufacturer attribution for the KS-19, a radar-directed 100 mm Soviet anti-aircraft gun accepted into service in the late 1940s.
The surviving public record is thin and sometimes inconsistent: some references use the Plant No. 4 Perm attribution, while other KS-19 references name other Soviet numbered plants for production totals and later variants. This archive therefore treats the profile as a sourced catalog manufacturer facet rather than a fully resolved modern corporate lineage.

Soviet KS-19 production period
WeaponSystems.net gives 1948-1957 as the Soviet production period for the KS-19 family, while identifying a different producer set than the Plant No. 4 Perm attribution used by NDU Ukraine.
Sources: WeaponSystems.net KS-19 reference
No official website, headquarters record, or rights-clear facility image was located for Plant No. 4 Perm as a Soviet numbered-plant attribution. The profile uses the NDU Ukraine KS-19 page as the website/reference URL required by the builder schema and avoids asserting a modern successor because public KS-19 sources disagree on the exact Soviet production plants.
