- The Australian Defence Force has operated Boeing CH-47 Chinook heavy-lift helicopters for most of the period since 1974. Thirty four of the type have entered Australian service, comprising twelve CH-47C variants, eight CH-47Ds and fourteen CH-47Fs. The helicopters have been operated by both the Royal Australian Air Force (RAAF) and Australian Army. An initial order of eight Chinooks for the RAAF was placed in 1962, but soon cancelled in favour of more urgent priorities. The Australian military still required helicopters of this type, and twelve CH-47C Chinooks were ordered in 1970. The CH-47s entered service with the RAAF in December 1974. The eleven surviving Chinooks were retired in 1989 as a cost-saving measure, but it was found that the Australian Defence Force's other helicopters could not replace their capabilities. As a result, four of the CH-47Cs were upgraded to CH-47D standard, and returned to service in 1995 with the Australian Army. The Army acquired two more CH-47Ds in 2000 and another pair in 2012. The CH-47Ds were replaced with seven new CH-47F aircraft during 2015, and another three were delivered in 2016. A further four CH-47Fs were ordered in 2021, with two being delivered that year and two others arriving in 2022. The Chinooks have mainly been used to support the Australian Army, though they have performed a wide range of other tasks. Three Chinooks took part in the Iraq War during 2003, when they transported supplies and Australian special forces. A detachment of two Chinooks was also deployed to Afghanistan during the northern spring and summer months for each year between 2006 and 2007 and 2008 to 2013, seeing extensive combat. Two of the CH-47s deployed to Afghanistan were destroyed in crashes. The helicopters have also frequently been assigned to assist recovery efforts following natural disasters and undertook a range of civilian construction tasks while being operated by the RAAF. (en)
