Australian Maritime Doctrine serves as the Royal Australian Navy's (RAN) principal doctrinal text, offering a comprehensive guide to understanding the Navy's role in Australia's national security and its operational approach. The book integrates key concepts of sea power within an Australian context, detailing the RAN's contributions to maritime security and its collaboration within the Australian Defence Force (ADF). This updated edition builds on the foundational principles established in the first edition, reflecting recent international developments such as the Global Maritime Partnership and Proliferation Security Initiative. Designed for a broad audience, including Navy personnel, ADF members, and the public, the doctrine underscores the enduring relevance of maritime strategy and the RAN's commitment to global maritime affairs. It is an essential resource for enhancing the Navy's operational knowledge and public understanding of Australia's maritime interests.
