The football club was one of the first two at the PZL Mielec, established in 1939. The team was made up of players playing in other clubs in Mielec and employees of the PZL, an aerospace company. In the first match played, the team defeated the Gymnastic Society "Sokół" Mielec with 4–1 victory. Three more matches were played against Dzikovia Tarnobrzeg, Metal Tarnów and a team made up of players from an ammunition factory in Nowa Dęba. The match against Okęcie Warszawa planned for September did not take place, because World War II started and any sports games were forbidden. However, the matches were played illegally in the meadows beyond the communal forest and in other towns. The only official match was played against a German military unit and ended with the score 1–2.
The construction of the club's current stadium, Stadion Stali Mielec at Solskiego 1, was concluded in 1953. The stadium underwent a major renovation, completed in 2013. It maintains a seating capacity for 7,000 spectators. Before the 2013 renovation, it maintained seating capacity for 30,000 spectators, and hosted numerous European Champions Cup, UEFA Cup, and Polish national team matches, including FIFA World Cup and UEFA European Championship qualifiers.
