Mielec's economy has been based for the last 70 years around a single industrial enterprise, which transformed the city and increased its population sixfold. This process began in the 1930s, when Poland launched a significant expansion of its armaments industry, focused on building factories in the newly created Central Industrial Region (Polish: Centralny Okręg Przemysłowy, abbreviated COP). In 1936, a state-owned factory making airplane chassis was established (State Aviation Works - Airframe Fakcory No. 2) on the outskirts of the town, an area then known as Cyranka. The factory started to build a new bomber, the PZL P-37 or "Łoś" (English: "Moose"). Additionally, in the years 1937-1939 a large aviation factory belonging to the PZL company was set up. This new manufacturing industry necessitated the development of residential housing for factory workers and management personnel.
