HMS ''Trafalgar'' was one of two ''Trafalgar'' class battleships commissioned in 1890 and 1891, the other being HMS ''Nile''. The ship was designed as an improved version of existing battleships with greater displacement and a thicker armoured belt amidships. The ''Trafalgar'' saw active service as a battleship from 1890 to 1897 and from 1909 to 1911 when she was sold. Between these two periods as a combatant, the ''Trafalgar'' served as a guardship and as a drill ship. ==Design== The two ships were designed to be improved versions of the Admiral and ''Victoria'' classes, having a greater displacement to allow for improved protection. However they sacrificed a full armoured belt for greater thickness amidships in a partial belt. As originally designed, ''Trafalgar'' was to have displaced 11,940 tons, and carried a secondary armament of ten guns of calibre, disposed in the broadside battery. Changes made during construction however, led to an increase in displacement to 12,590 tons; this led to the ships draught being increased by from the initial design, and with full bunkers. This in turn led to the main belt being immersed to a deeper level than had been intended, with a potential decrease in defensive effect in combat. In October 1896 the secondary battery of guns was replaced by a more powerful battery of six quick firers. The main artillery, while situated at a militarily effective height of above sea level, were only above the deck. It was thought possible that firing along the keel line might cause structural damage; tests requested by the Chief Constructor, however, showed the potential damage to be minimal. As compared to HMS ''Sans Pareil'', ''Trafalgars under-water hull form was finer, with a larger rudder. Together with the reduced freeboard as compared to earlier ships, this had a significantly adverse effect on her handling; as she spent her active service in relatively calm water in the Mediterranean, however, this defect was of minimal importance. 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「HMS Trafalgar (1887)」の詳細全文を読む スポンサード リンク
