Charts a century of destroyer, frigate and submarine development, starting with the earliest vessels, through the two world wars and the Cold War, through to the machines planned for construction in the 21st century. This book offers chronological directories for each type of vessel, from the earliest torpedo boats and first attempts. Each entry is accompanied by technical information, such as origin, length, displacement, speed, armament and propulsion. The boxes provide information about each vessel's country of origin, displacement, dimensions, armament, machinery, power, performance and protection. This volume is divided into two parts, the first half focussing on the history of destroyers and frigates, and the second on the submarine.
