An engineer's survey traces the material evolution of naval warfare by treating ship, gun, and engine as interconnected elements. It moves from oar-driven galleys and early sailing vessels through the adoption of gunpowder and navigational tools to detailed treatments of smooth-bore, shell, and rifled ordnance, gun carriages, and the carronade. Parallel chapters explain steam propulsion, propellers, and the rise of iron construction, using technical diagrams, plates, and historical examples to show how advances in construction, armament, and machinery reshaped naval architecture, seagoing performance, and combat practice into the modern era.
