The Hellenic Air Force Museum was founded in 1986 and since 1992 it is located on the Decelea Airfield. In opposition to the War Museum of Athens it displays air force history and is active in restoring and presenting old aircraft. The most aircraft in the collection come from the Hellenic Air Force, some were exchanged with other European Aircraft Museums.
The HAF Underwater Operations Team (KOSYTHE) helped recover some rare airplanes from underwater for the museum: A Bristol Blenheim, a Junkers 52 and a Junkers 87 (Stuka).
