Recent challenges to US maritime predominance suggests a return to great power competition at sea, and this new volume looks at how navies in previous eras of multipolarity grappled with similar challenges. "Multipolar Worlds is an important correction to the fallacy that either multipolarity or complexity are new elements in maritime strategy. At a time when the world's navies are struggling to understand the strategic and technological challenges they face, these essays provide insights into the historical and contemporary role of seapower that will be of value to decision makers at many levels."-- RADM (ret.)
