The Wikipedia article of the day for October 7, 2017 is No. 1 Wing RAAF.
No. 1 Wing was an Australian Flying Corps and Royal Australian Air Force wing active during World War I and World War II. Established in September 1917 as the 1st Training Wing, it commanded Australian pilot training squadrons in England until April 1919, when it was disbanded. It was re-formed as No. 1 Wing on 7 October 1942 as a fighter unit of one British and two Australian 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. During its first months at Darwin, its fighters intercepted several air raids on 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 a greater number of Japanese aircraft than it lost in combat. The wing’s two Australian flying squadrons were replaced with British units in July 1944, and it was disbanded after the war.
