This large encampment, comprising several barracks and military administrative buildings such as Roberts Barrack and Selarang Camp, were used together with the nearby Changi Prison (previously a maximum-security incarceration complex for civilians) for housing many of the Allied prisoners-of-war (POWs) after Japan took over control of Singapore.

Completed post-war, non-flying RAF Chia Keng — a GCHQ radio-receiving station, was a satellite station of RAF Changi (being the Headquarters Air component part of British Far East Command) until the withdrawal of British troops from Singapore at the end of the 1960s.

The novel 'The Sound of Pirates' by former RAF airman Terence Brand is based in the 1960s both on the airfield and in the surrounding areas.

In June 1975, the Singapore government acquired about two-thirds of the airbase (saved for the main flight-line, hangar/aircraft maintenance facilities and control tower which were located in the western section of the airbase) for the construction of the new Singapore Changi Airport, with the new runways in close alignment with the original north–south runway.

The east–west runway was almost erased from the map, currently surviving as a taxiway to the apron area which has remained operational as part of Changi Air Base.
