Submarine cruiser for service in Red sea and Indian ocean. Design was developed by builder. Single-hulled, with external bulges. According to the design, Ettore Fieramosca should carry a seaplane in watertight hangar. For some reasons aircraft have not created, and in 1931 hangar because of which the diving time has appeared unreasonably long, was liquidated. After that submerged displacement was moderated from 2094 to 1934t and the diving time was a little shrank, though continued to be considered as the excessive.
Ettore Fieramosca, as well as Balilla class, could not reach a designed speed (19/10kts), but, unlike the later, at expense of application of the bulges had better stability.
1931: - 1 x 1 - 120/27, hangar; + 1 x 1 - 120/45 OTO 1931
Too large for service in Mediterranean sea, after battery explosion in the mid-1940 she as laid up to reserve and disarmed in April, 1941 and broken up in 1946.
