Italian submarine Ettore Fieramosca

Ettore Fieramosca was an Italian submarine which served with the Regia Marina in World War II. She was named after Ettore Fieramosca, an Italian condottiero of the 16th century. == Design == Ettore Fieramosca was designed by the firm Bernardis and was intended to be a cruiser submarine which carried a seaplane in a waterproof hangar and a 203 mm (8 in) gun; such a design was inspired by the similar (although bigger) Surcouf, then under construction in France.
