No. 1 Wing RAAF

No. 1 Wing was an Australian Flying Corps (AFC) and Royal Australian Air Force (RAAF) wing active during World War I and World War II. The wing was established on 1 September 1917 as the 1st Training Wing and commanded the AFC's pilot training squadrons in England until April 1919, when it was disbanded. It was reformed on 7 October 1942 as a fighter unit comprising two Australian and one British flying squadrons equipped with Supermarine Spitfire aircraft, and a mobile fighter sector headquarters. The wing provided air defence to Darwin and several other key Allied bases in northern Australia until the end of the war, and was again disbanded in October 1945.

During its first months at Darwin, No. 1 Wing intercepted several of the air raids conducted against Northern Australia by the Imperial Japanese Army Air Force and Imperial Japanese Navy. Although the wing was hampered by mechanical problems with its Spitfires and suffered heavy losses in some engagements, it eventually downed more Japanese aircraft than it lost in combat. After the final Japanese air raid on northern Australia in November 1943, No. 1 Wing saw little combat, which led to its personnel suffering from low morale. The wing's two Australian flying squadrons were replaced with British units in July 1944, and subsequent proposals to move these squadrons to more active areas were not successful.
