The Boeing CH-47 Chinook is a versatile, twin-engine, tandem rotor heavy-lift helicopter. Its top speed of 170 knots (315 kilometres per hour) is faster than many contemporary utility and attack helicopters. Its primary roles include troop movement, artillery emplacement and battlefield resupply. There is a wide loading ramp at the rear of the fuselage and three external-cargo hooks underneath. With more powerful engines, larger composite rotor blades and advanced avionics systems, the latest Chinook is faster than many attack helicopters.

By having two contra-rotating rotors front and rear of the aircraft, the Chinook eliminates the need for a traditional rear vertical rotor. As both rotors turn in opposite directions, the torque they apply to the helicopter is cancelled out. This arrangement also creates extra lifting capacity by having all of the engine's power dedicated to lift and thrust. The Chinook is the largest helicopter in the Australian Army, and is one of the most versatile.
The Chinook capability assurance program will ensure the Australian CH-47F is aligned with the US Army CH-47F fleet over the life of type. This will be a key enabler for interoperability with the US in future coalition operational environments. It will also acquire any Australian specific systems required for interoperability with other selected ADF assets.
