Australian Fleet Unit

The concept of the Australian Fleet Unit arose out of the discussions concerning the role and structure of the proposed Australian Navy that took place between 1907 and 1909. Generally, Australian naval authorities favoured a force of destroyers to protect ports and sea lanes, while the British Admiralty sought to convince them that what they needed was a "fleet unit", based around a battle-cruiser and several cruisers, that would form part of Britain's global naval force. In 1909 Australia agreed to purchase a fleet unit, which was ultimately planned to consist of a battle-cruiser, three cruisers, six destroyers and three submarines, under the proviso that it would remain solely under Australian control during peace, and be placed at the disposal of the Admiralty in time of war.
