This book examines Anglo-Australian naval relations between 1945-75, a period of great change for both Australia and Great Britain and their respective navies. It explores the cultural and historical ties between the Royal Navy and the Royal Australian Navy (RAN), the efficacy of communications between the services, and the importance of personal relations to the overall inter-service relationship. The author assesses the dilemmas faced by Great Britain associated with that nation’s declining power, and the impact of the retreat from ‘East of Suez’ on the strategic relationship between the United Kingdom and Australia. The book also considers operational co-operation between the Royal Navy and the RAN including conflicts such as the Korean War, the Malayan Emergency, and confrontation with Indonesia, as well as peacetime pursuits such as port visits and the testing of atomic weapons in the 1950s. Co-operation in matters of personnel and training are also dealt with in great detail, along with the co-operation between the Royal Navy and the RAN in equipment procurement and design and the increased ability of the RAN to look to non-British sources for equipment procurement. The book considers the impact of stronger Australian-American ties on the RAN and appraises the role it played in the conflict in Vietnam.
