This work presents a selective review of naval power, changes in power that have occured over time, and the employment of that power during peace and war times. The volume arose from Hooper's concern over national military policies that seem to ignore the lessons of the past and demonstrate a lack of understanding of the continued relevance of naval power. Hooper pays particular attention to naval policy; naval capabilities and mission; determinants and influence of naval power; management of naval affairs; exercise of command over operating forces; and interservice relationships.
