The ''Vettor Pisani'' class consisted of two armoured cruisers built for the Royal Italian Navy (''Regia Marina'') in the 1890s. The two ships of the class, ''Vettor Pisani'' and ''Carlo Alberto'', were frequently deployed overseas during their careers. The former served in the Far East during the Boxer Rebellion of 1900 while the latter was involved in pioneering long-range radio experiments several years later before deploying to South American waters. ''Carlo Alberto'' then served as a training ship for several years. Both ships participated in the Italo-Turkish War of 1911–12 and played minor roles in World War I, during which time ''Carlo Alberto'' was converted into a troop transport and ''Vettor Pisani'' into a repair ship. They were both discarded in 1920 and subsequently scrapped. ==Design and description== The ships of the class had a length between perpendiculars of and an overall length of . They had a beam of and a draft of . They displaced at normal load, and at deep load.〔Gardiner, p. 350〕 The ''Vettor Pisani'' class had a complement of 28 officers and 472 to 476 enlisted men.〔 The ships were powered by two vertical triple-expansion steam engines, each driving one propeller shaft. Steam for the engines was supplied by eight Scotch marine boilers and their exhausts were trunked into a pair of funnels amidships. Designed for a maximum output of and a speed of ,〔Silverstone, p. 286〕 both ships exceeded their designed power during their sea trials although only ''Carlo Alberto'' met her designed speed. The two had a cruising radius of about at a speed of .〔 The main armament of the ''Vettor Pisani''-class ships consisted of twelve quick-firing (QF) Cannone da 152/40 A Modello 1891 guns in single mounts. These weapons had 40-caliber barrels. All of these guns were mounted on the broadside, eight on the upper deck and four at the corners of the central citadel in armored casemates. The M1891 guns weighed and fired a , armor-piercing, capped shell at a muzzle velocity of .〔Friedman, p. 240; Silverstone, p. 268〕 Single 40-caliber QF Cannone da 120/40 A Modello 1891 guns were mounted at the bow and stern and the remaining two or four guns were positioned on the main deck between the 152 mm guns. The armor-piercing shell had a muzzle velocity of when fired by these guns. For defense against torpedo boats, the ships carried fourteen QF guns and six or eight QF Hotchkiss guns.〔Friedman, pp. 240, 243; Silverstone, p. 268〕 They were also equipped with four torpedo tubes.〔Fraccaroli, p. 28〕 The ships were protected by an armored belt that was thick amidships and reduced to at the bow and stern.〔 The upper strake of armor was also 15 cm thick and protected just the middle of the ship, up to the height of the upper deck. The curved armored deck was 3.7 cm thick. The conning tower armor was also 15 cm thick and each 15.2 cm gun was protected by a gun shield.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Vettor Pisani-class cruiser」の詳細全文を読む スポンサード リンク
