The ''Alsedo'' class was a Spanish class of destroyer. Three ships were built, based on a British design, entering service from between 1924 and 1925. They all served through and survived the Spanish Civil War, two on the Republican side and one with the Nationalists, with the class finally retired in 1957–61. ==Design and construction== On 17 February 1915, the Spanish Cortes (Parliament) passed a navy law authorising a large programme of construction for the Spanish Navy, including three destroyers of British design, the ''Alsedo'' class, to be built in Spain at the Sociedad Española de Construcción Naval (SECN) dockyard at Cartagena.〔〔Gardiner and Gray 1985, p. 376.〕 The design chosen was similar to the Hawthorn Leslie variant of the M-class destroyer, a reasonably modern design for 1915. The ship was propelled by two geared steam turbines driving two shafts, and fed by four Yarrow boilers, giving a distinctive four-funneled silhouette. This machinery gave the ships a design speed of , although ''Alsedo'' did reach a speed of during trials before its armament was fitted.〔Whitley 2000, pp. 242–243.〕 The ship's main gun armament consisted of three Vickers guns (license-built in Spain) in three single mounts, with one forward, one aft the third gun between the second and third funnels, while two 47 mm anti-aircraft guns protected against air attack. Four torpedo tubes were mounted in twin banks, with the class being the first Spanish destroyers to carry torpedoes of this size.〔 The ships were not laid down until 1920, as the First World War caused shortages of materials and equipment sourced from Britain. By this time, destroyer design had moved on, and the ''Alsedo'' class was obsolete, so plans to build a further three ships of the class were reconsidered, with a modern and much larger design selected which became the .〔 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「Alsedo-class destroyer」の詳細全文を読む スポンサード リンク
