Project history

Designed on the basis of Regina Elena class battleships. Originally according to Italian classification they were rated as 2nd class battleships though had strongly pronounced cruiser characteristics. As a whole they were rather successful ships for time, but to beginning of WWI they already considerably become outdated.

Ship protection

Main 200mm belt (full ship length, tapering to 80mm at lower edge), medium belt between end turrets and upper belt between 190mm gun turrets expanded to upper deck, main and upper belts were closed by 150mm bulkheads abreast barbettes. Main belt thickness was 100mm on short parts at ship ends. Main 50mm deck was connected with lower edge of main belt by 130mm slopes. CT had 180mm sides.
