The Australian Army received two CH-47 Chinook helicopters, taking the total number of this aircraft in service to 12.
Australia acquired four Chinooks via a foreign military sales agreement for approximately AUD595 million ($441.6 million). The first two aircraft, drawn from U.S. Army stock, were delivered to the Townsville-based 5th Aviation Regiment on 7 July by a U.S. Air Force C-5M Galaxy transport.
Approved by the U.S. State Department in May, the deal also includes eight T55-GA-714A aircraft turbine engines; five AN/AAR-57 Common Missile Warning Systems (CMWS); eight Embedded Global Positioning System (GPS)/Inertial Navigation Systems (INS/EGI) +429; and two EAGLE+429 Embedded Global Positioning System (GPS)/Inertial Navigation Systems (INS/EGI).
The third and fourth CH-47F Chinook helicopters are scheduled to be delivered in mid-2022.
