No. 3 Squadron is a Royal Australian Air Force (RAAF) fighter squadron, headquartered at RAAF Base Williamtown, near Newcastle, New South Wales. Established in 1916, it was one of four combat squadrons of the Australian Flying Corps during World War I, and operated on the Western Front in France before being disbanded in 1919. It was re-raised as a permanent squadron of the RAAF in 1925, and during World War II operated in the Mediterranean Theatre. The Cold War years saw the squadron disbanded and re-raised twice. It was based at RAAF Butterworth during the Malayan Emergency and the Indonesia–Malaysia "Konfrontasi". Equipped with &lt;a href="McDonnell%20Douglas%20F/A-18%20Hornet"&gt;McDonnell Douglas F/A-18 Hornet&lt;/a&gt; multi-role fighters from 1986, the squadron deployed to Diego Garcia in 2002 to provide local air defence, and the following year contributed aircraft and crews to the invasion of Iraq as part of Operation Falconer. In April 2016, it deployed to the Middle East as part of the military intervention against ISIL.
