Originally comprising five ships in two related classes, Conte di Cavour and Duilio classes entered service at the beginning of the Great War. As designed, they were powerful examples of the second generation of dreadnoughts, with a combination of twin and triple turrets producing a unique main armament of thirteen 12-inch guns.
This book covers all the technical details of the ships, both as built and as rebuilt, but also provides an extended history of their active service, including battle plans and track charts.
