Italian cruiser Bolzano

Bolzano was a unique heavy cruiser built for the Italian Regia Marina in the early 1930s, the last vessel of that type built by Italy. She is sometimes counted as a member of the Trento class, but she was a modified version of it, with a heavier displacement, a slightly shorter hull, a newer model of 203 mm gun and a more powerful propulsion system, changes influenced by the Zara class that followed. Gio. Ansaldo and C. built her between her keel laying in June 1930 and her commissioning in August 1933. After a peacetime career of naval reviews she saw extensive action in the first three years of Italy's part in World War II, including the battles of Calabria, Taranto, Cape Spartivento and Cape Matapan, until a British submarine torpedo ended her career in August 1942. She was sunk by Italian and British frogmen in June 1944, then raised and scrapped.
