Wytwórnia Sprzętu Komunikacyjnego „PZL-KALISZ S.A. is a company with a long tradition. The origins of the production plant date back to 1941, when the Germans started erecting the “Zollern – WerkeWeserFlug” buildings complex for industrial use. After World War II, in 1946 the manufacture was nationalised, and its name changed into National Car Plant. The new name reflected the work profile. The plant repaired lorries and passenger cars, as well as combustion engines.

Throughout the years the plant changed its name and work profile several times:

  • National Car Plant – 1946,
  • Car Parts Plant – 1949,
  • Kalisz Car Repairing Plant – 1951,
  • Communication Equipment Factory „Delta-Kalisz” – 1952

The company got its contemporary name WSK “PZL-KALISZ” S.A. on 17th October 1996. On the basis of Article 17 of the Act of Law of 3rd February 1993 on financial restructuring of companies and banks and changes of some acts of law, the national company was commercialised, which led to creating commercial law company.
