Plant No. 4 Perm
Plant No. 4 Perm was a Soviet numbered defense plant attribution tied in open reference material to the 100 mm KS-19 anti-aircraft gun, a heavy towed air-defense weapon accepted into Soviet service in 1948.
1 weaponsNational Defence University of Ukraine identifies Plant No. 4, Perm as the manufacturer for the AZP KS-19 and describes the weapon as a radar-directed 100 mm gun developed in 1947 for high-altitude air defense. Its summary gives the gun's Soviet service entry as 1948, with a 21 km firing range, approximately 15 km altitude reach, and automatic firing based on radar-system data.
The surviving public record is thin and partly contradictory because Soviet numbered-plant reporting is not consistent across later references. The NDU page gives the Plant No. 4 Perm attribution, while its own production paragraph and WeaponSystems.net point to Plant No. 8 and Plant No. 235 for quantified KS-19, KS-19M, KS-19M2, and KSM-65 production. The most useful public context for Plant No. 4 Perm is therefore its documented connection to the early KS-19 family rather than a complete corporate lineage.

Soviet KS-19 production period
NDU Ukraine says 10,151 KS-19 guns of several modifications were produced from 1948 to 1955, while WeaponSystems.net summarizes the broader KS-19 family production period as 1948-1957.
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 NDU Ukraine KS-19 page is used as the primary reference URL, and no modern successor is asserted because public KS-19 sources disagree on the exact Soviet production plants.
