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.
