An effective organisation is fundamental to the efficiency of the RAN and its ability to accomplish assigned missions. The objective of the RAN’s structure is to align the entire Service, and its supporting agencies, into a system that is focused on the delivery of trained forces and the necessary support to deliver combat capability. Ultimately the Navy’s mission is to fight and win at sea.

The Chief of Navy Australia commands the Navy and is responsible for raising, training and sustaining the RAN. Under the Chief of Navy Australia there are two major commands, Navy Headquarters and Fleet Command.
