This new book explores innovation within the Royal Navy from the financial constraints of the 1930s to World War Two, the Cold War and the refocusing of the Royal Navy after 1990. Successful adaptation to new conditions has been critical to all navies at all times. To naval historians the significance and process of change is not new, but in recent years innovation has been increasingly studied within a number of other disciplines, providing new theoretical positions and insights. This study examines key case studies of change, some successful others less so, which place the experience of the Royal Navy within a variety of economic and strategic contexts. Together these studies provide excellent new insights against which to set recent ideas on innovation and provide a stimulus to more research by historians and scholars in other disciplines.
