Project history

Vice-Admiral Saint Bon, then minister of the Navy, proposed a medium-sized battleship, as a more convenient type for the Italian Navy and also as a reaction to the huge and expensive battleships of the previous classes. On his death (November 1892), the temporary minister Brin and the new one, Vice-Admiral Racchia, ordered some modifications to the original project. So modified, the Saint Bons were laid down in 1893. They had a low freeboard (only 3m from the upper deck to the waterline) and heavy guns of reduced calibre (even though the model fitted was a remarkable design), and were not powerful ships; even if one considers them as a half-measure between a battleship and a cruiser, it must be admitted that the speed of 18kts was low for a cruiser.

Ship protection

Ships were protected by 250mm belt on full ship length and 70mm deck above.



Naval service

Had it not been for the outbreak of the First World War, the Saint Bons would have been broken up in about 1914-15. The two vessels were commissioned before completion, Ammiraglio di Saint Bon on 1.2.1901 and Emanuele Filiberto on 6.9.1901.
