The Chinook is an extremely capable and highly versatile support helicopter that can be operated from land bases or ships into a diverse range of environments, from the Arctic to the desert or jungle. The aircraft may be armed and is fitted with a suite of self-defence equipment allowing it to operate across the battlespace. Chinooks are primarily used for trooping, resupply and battlefield casualty evacuation (casevac).

With its triple-hook external load system, internal cargo winch, roller conveyor fit and large reserves of power, the aircraft can lift a wide variety of complex underslung or internal freight, including vehicles. It can carry up to 55 troops or up to approximately 10 tonnes of mixed cargo.
