The book surveys late nineteenth-century naval construction and armament, tracing the evolution from wooden sailing vessels to armored, turreted, and steel-hulled warships. It provides comparative examinations of major national navies and detailed technical descriptions and sectional plans of ship types, armor schemes, propulsion, and fittings. Dedicated chapters analyze naval artillery, rapid-fire guns, torpedoes, and submarine warfare. Appendices address the classification of types, reserve forces, forced-draft systems, and gun ranges. Numerous illustrations and plates clarify constructional features, while commentary links engineering detail to operational and strategic considerations.
