2 X Boeing CH-47 Chinook Army helicopters

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.

The ship helps provide the Australian Defence Force (ADF) with one of the most capable and sophisticated air-land-sea amphibious deployment systems in the world. Today appears to be a training operation.
