The Air Force Museum in Dęblin, established on April 1, 2011, is an important cultural institution that collects and preserves exhibits related to the history of Polish aviation. Its grand opening took place on August 26, 2011, and the museum aims to promote knowledge about Polish military history through various educational and cultural activities. The museum's collections include both aircraft and documents related to the operations of the Air Force. The museum carries out diverse projects, such as the restoration of exhibits and the organization of permanent and temporary exhibitions. The collections are dominated by military technology artifacts and personal memorabilia of soldiers. In Dęblin, a historic city associated with Polish aviation, the museum also explores the regional histories of communities connected to aviation. Interestingly, a number of aircraft, including unique specimens, were acquired through grants and modernization phases, which contributed to the development of the exhibition. The Anti-Aircraft Defense Museum in Koszalin, as a branch of the Air Force Museum, continues the traditions of the former museum from 1976, and its modern exhibition presents the history of anti-aircraft weapons in Poland.
