From its origins in 1901 until the late 1950s, through its deep association with the Royal Navy, the Royal Australian Navy became unmistakably British in outlook, practices and culture. It was a relationship of great value to Australia. That comfortable symbiosis had reached its zenith by 1957, when Prime Minister Robert Menzies announced to parliament that Australia would be moving towards standardising Australia’s military services with those of the United States.
The outcome of that decision was that the RAN would successfully transition to be a highly valued ally of the US Navy, already the RN’s replacement as the world’s most powerful maritime force. On that journey, the RAN progressively underwent a major transformation in virtually every dimension, the catalyst for which was its operation of the Charles F. Adams–class guided-missile destroyers.
