The ''Nembo'' class was a class of destroyer of the Italian ''Regia Marina'' (Royal Navy). Six destroyers were built by the Pattison shipyard of Naples between 1899 and 1905, to a design based on the comtemporary destroyers of the British shipyard Thornycroft. They were active in the Italo-Turkish War and in the First World War, where three were lost. ==Design== In 1899, work began on at the Pattison shipyard of Naples on the first ships of a new class of destroyers, the ''Nembo'' class. The ''Nembo'' class were based on a design by the British shipbuilders Thornycroft, and were similar to the Thirty-knotter destroyers that Thornycroft were building for the British Royal Navy (such as ).〔Friedman 2009, p. 50.〕 The ships were long overall and between perpendiculars, with a beam of and a draught of . Displacement was normal and full load.〔Chesneau and Kolesnik 1979, p. 356.〕 Three Thornycroft boilers fed steam to two triple expansion steam engines rated at and driving two propeller shafts, giving a design speed of .〔〔Fraccaroli 1970, p. 65.〕 The ships featured a raised turtleback forecastle and two funnels.〔''Purnell's Illustrated Encyclopedia of Modern Weapons and Warfare'', p. 1877.〕 Crew was between 51 and 58 officers and men.〔 The first two ships of the class, and were armed with one 76 mm (3 in)/40 calibre gun (capable of firing a shell to a range of at a rate of fire of 15 rounds per minute per gun〔Fraccaroli 1970, pp. 281–282.〕) and five 57 mm/43 guns, with two 356 mm (14 in) torpedo tubes,〔 while the remaining four ships had a reduced gun armament of five 57 mm/43 guns, allowing an increased torpedo armament of four 356 mm torpedo tubes to be carried.〔 The six ships of the class were completed between 1902 and 1905, reaching speeds of up to during sea trials (corresponding to a realistic sea speed of ).〔 ''Nembo'' and ''Turbine'' were rearmed in 1905 to match the other four ships.〔 From 1908, all ships of the class were fitted with new oil-fired boilers, with a resulting change in the ships' profile, with three funnels being fitted rather than two. Sufficient oil was carried to give a range of at or at . The ships' armament was changed at the same time, to four 76 mm/40 guns and two 450 mm (18 in) torpedo tubes.〔 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「Nembo-class destroyer」の詳細全文を読む スポンサード リンク
