SMS ''Tegetthoff'' was an Austro-Hungarian dreadnought battleship of the named after Wilhelm von Tegetthoff, a 19th-century Austrian admiral most notable for defeating the Italian Navy in the Battle of Lissa. ''Tegetthoff'' was built at the Stabilimento Tecnico Triestino yard in Trieste as part of the first and only class of dreadnought battleships in the Austro-Hungarian Navy. After her construction in 1912, an earlier armoured battleship named was renamed ''Mars''. During World War I, ''Tegetthoff '' participated in the bombardment of the Italian city of Ancona. She remained in port in Pola for the rest of the war until she participated in an ill-fated raid on the Otranto Barrage in 1918 that resulted in the loss of her sister ship, . Following the end of the war in late 1918, ''Tegetthoff'' was surrendered to Italy and later scrapped in 1924. == Characteristics == (詳細はclass that shared her name to be built, the first dreadnoughts of the Austro-Hungarian Navy. The keel of ''Tegetthoff'' was laid down in Stabilimento Tecnico Triestino shipyard in Trieste on 24 September 1910. Following a year and a half of construction, ''Tegetthoff'' was launched on 21 March 1912. Following her fitting out, she was commissioned into the Austro-Hungarian navy on 14 July 1913.〔 The ship had an overall length of , a beam of , and a draught of at deep load. She displaced at load and at deep load. The propulsion consisted of four Parsons steam turbines, each of which was housed in a separate engine-room. The turbines were powered by twelve Babcock & Wilcox boilers. The turbines were designed to produce a total of , which was theoretically enough to attain her designed speed of , but no figures from her speed trials are known to exist. She carried of coal, and an additional of fuel oil that was to be sprayed on the coal to increase its burn rate. At full capacity, she could steam for at a speed of . Her armament consisted of twelve /45-caliber K 10 guns in four triple turrets. Her secondary armament consisted of twelve /50 K 10 guns mounted in casemates amidships. Eighteen /50 K 10 guns were mounted on open pivots on the upper deck above the casemates. Three more 66-mm K 10 guns were mounted on the upper turrets for anti-aircraft duties. Four submerged torpedo tubes were fitted, one each in the bow, stern and on each broadside; twelve torpedoes were carried. The waterline armour belt of ''Tegetthoff'' measured thick between the midpoints of the fore and aft barbettes and thinned to further towards the bow and stern, but did not reach either the bow or the stern. It was continued to the bow by a small patch of armour. The upper armour belt had a maximum thickness of , but it thinned to from the forward barbette all the way to the bow. The casemate armour was also thick. The sides of the main gun turrets, barbettes and main conning tower were protected by of armour, except for the turret and conning tower roofs which were thick. The thickness of the decks ranged from in two layers. The underwater protection system consisted of the extension of the double bottom up to the lower edge of the waterline armour belt, with a thin plate acting as the outermost bulkhead. It was backed by a torpedo bulkhead that consisted of two layered 25-millimetre plates. The total thickness of this system was only which made it incapable of containing a torpedo warhead detonation or mine explosion without rupturing. 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「SMS Tegetthoff (1912)」の詳細全文を読む スポンサード リンク
