Prior to 1989, the battle honour system of the Royal Australian Navy (RAN) was linked to that of the Royal Navy. The British Ministry of Defence and the Admiralty were responsible for approving and assigning battle honours, although from 1947, this was done on advice from the RAN Badges, Names and Honours Committee. The only uniquely Australian battle honour during this time was "Vietnam 1965–72" (and smaller date units thereof) for deployments to the Vietnam War. Ships of the RAN inherited honours from British ships of the same name, in addition to Australian predecessors.
