The 21st century is witnessing renewed tension as conflicts between major powers, serious concerns about future security alliances and global, even generational, security policy challenges arise. In the light of this, naval forces and maritime security, and understanding their underlying strategic rationale, are gaining momentum and importance. What are the roles and missions of naval forces, and how have states and the institutions themselves sought to frame their goals and methods? This book brings together experts from the United States, Europe, and Asia to reflect on how maritime and naval strategy is conceptualised and how it has been used. It celebrates the life and work of Peter M. Swartz, Captain (US Navy) ret., who since contributing to The Maritime Strategy of the 1980s as a young Pentagon officer, has been a mentor, friend, intellectual beacon and the foremost purveyor of maritime expertise to the global naval community.
