The Japanese air raid on Darwin was mounted by 242 Japanese planes launched from four aircraft carriers. It was intended to soften up the air force and navy bases there in preparation for the Japanese invasion of Timor the following day. Between 9:58 and 10:40AM that day, the planes sank three warships and five merchant ships, while damaging ten more. Twenty-one dock workers were killed in the raids.
This would be the first of a total of 97 air raids against targets either in Australian waters or on the Australian mainland. Most of these were on various sites across the northern coast of Australia between Port Hedland, Western Australia and Townsville, Queensland, with the great majority of them being on military or civilian targets in Darwin. The last air raid took place on November 12, 1943, striking Parap, Adelaide River and Batchelor Airfield (all in the Northern Territory). By that time, the tide of war had turned, and Japan could no longer strike so close to Australia, although the end of the war was still nearly two years away.
