 Once war was declared , Darwin began to receive more attention from military planners . In June 1940 , No. 12 Squadron was " <unk> " to form two additional units , Headquarters RAAF Station Darwin and No. 13 Squadron . No. 12 Squadron retained its <unk> flight , while its two flights of Ansons went to the new squadron ; these were replaced later that month by more capable Lockheed <unk> . Eaton was appointed CO of the base , gaining promotion to temporary group captain in September . His squadrons were employed in escort , maritime reconnaissance , and coastal patrol duties , the <unk> aircraft having to be sent to RAAF Station Richmond , New South Wales , after every 240 hours flying time — with a consequent three @-@ week loss from Darwin 's strength — as deep maintenance was not yet possible in the Northern Territory . Soon after the establishment of Headquarters RAAF Station Darwin , Minister for Air James <unk> visited the base . <unk> his own light plane , he was greeted by four Wirraways that proceeded to escort him into landing ; the Minister subsequently complimented Eaton on the " keen @-@ ness and efficiency of all ranks " , particularly considering the challenging environment . When <unk> died in the Canberra air disaster shortly afterwards , his pilot was Flight Lieutenant Robert Hitchcock , son of Bob Hitchcock of the Kookaburra and also a former member of Eaton 's No. 21 Squadron .
