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.


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-inch) gun; such a design was inspired by the similar (although bigger) Surcouf, then under construction in France. Several prototype seaplanes were designed but not deployed and the hangar was removed in 1931. The deck gun was initially a 12-cm (4.7-inch) 27-calibre OTO model of 1924, but this was later replaced by a 12-cm 45-calibre OTO model of 1931.[1]


Ettore Fieramosca was built by Tosi. She was laid down in 1926, launched on 15 April 1929 and completed in 1930. Plagued with incidents and mechanical trouble for all its career, she was deployed on operational patrols in 1940 but without any success. She suffered a battery explosion late in 1940 and was laid up for the remainder of the war.
