purposes in subsequent decades, such as the peacekeeping operations in East Timor from 1999. Australia's combat aircraft were not used again in combat until the Iraq War in 2003, when 14 F/A-18s from No. 75 Squadron RAAF operated in the escort and ground attack roles, flying a total of 350 sorties and dropping 122 laser-guided bombs. A detachment of AP-3C Orion maritime patrol aircraft were deployed in the Middle East between 2003 and 2012. These aircraft conducted maritime surveillance patrols over the Persian Gulf and North Arabian Sea in support of Coalition warships and boarding parties, as well as conducting extensive overland flights of Iraq and Afghanistan on intelligence, surveillance and reconnaissance missions, and supporting counter-piracy operations in Somalia. From 2007 to 2009, a detachment of No. 114 Mobile Control and Reporting Unit RAAF was on active service at Kandahar Airfield in southern Afghanistan. Approximately 75 personnel deployed with the AN/TPS-77 radar assigned the responsibility to co-ordinate coalition air operations. A detachment of IAI Heron unmanned aerial vehicles has been deployed in Afghanistan since January 2010. In late September 2014, an Air Task Group consisting of up to eight F/A-18F Super Hornets, a KC-30A Multi Role Tanker Transport, an E-7A Wedgetail Airborne Early Warning & Control aircraft and 400 personnel was deployed to Al Minhad Air Base in the United Arab Emirates as part of the coalition to combat Islamic State forces in Iraq. Operations began on 1 October. A number of C-17 and C-130J Super Hercules transport aircraft based in the Middle East have also been used to conduct airdrops of humanitarian aid and to airlift arms and munitions since August. In June 2017, two RAAF AP-3C Orion maritime patrol aircraft were deployed to the southern Philippines in response to the Marawi crisis. In 2021, the Royal Australian Air Force commemorated its 100th anniversary. Later that year, on 29 November, the Hornet was officially retired from RAAF service, with a ceremony to mark the occasion taking place that day at RAAF Base Williamtown. In January 2022, two RAAF P-8A Poseidon maritime patrol aircraft and one C-130J Hercules departed RAAF Amberley and Richmond to conduct aerial reconnaissance of Tonga in the wake of the 2022 Hunga Tonga–Hunga Ha'apai eruption and tsunami. According to Australian Defence News, the flights were to “help determine the extent of the damage [to Tongan infrastructure]… and inform future disaster support requests.” Structure Headquarters Air Force
