RAAF Base Curtin — Derby, Australia

RAAF Base Curtin, coded DCN, sits near Derby in the remote Kimberley region of Western Australia and functions as a Royal Australian Air Force facility. Named after wartime prime minister John Curtin, the base typically operates under a reduced 'bare base' caretaker status, becoming fully active during military exercises when personnel and aircraft are deployed for training in Australia's vast and sparsely populated north. DCN has also served non-military purposes at times, including a period when facilities near the base were used for immigration processing. Its isolated location, far from major population centers, reflects the strategic importance Australia places on maintaining a military air presence across its remote northern approaches.
