The Air Force Museum captures the spirit and heritage of the RSAF. The first museum was established at Changi Air Base on 1 Sep 1988. Two years later, an expansion programme was initiated to cater to RSAF's growing heritage needs. Subsequently, the museum was relocated to a brand new building in Paya Lebar.

The museum now resides on 10,600 m² of land, with a total built up area of 4,600 m². The exhibition area comprises mainly the outdoor gallery, eight indoor galleries on the second level and the history of aviation gallery on the first level. The theme for the entire display is "Men, Machine and Method".
