Despite being the first experience of the Italian Navy in the construction of "dreadnoughts", the battleship Dante Alighieri could be considered successful. Its short period of service, 15 years, was due essentially to the conviction of the Navy staff that the unit in the 1928 was now superseded by similar and more technologically advanced foreign units and by the emergence of new and advanced means of struggle: the aircraft as an effective offensive antinave means, the submarine and the underwater explosive devices.
