HMS Trafalgar (1887)
HMS Trafalgar was one of two s commissioned in 1890 and 1891, the other being. The ship was designed as an improved version of existing battleships with greater displacement and a thicker armoured belt amidships. 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, Trafalgar served as a guardship and as a drill ship.
Design
The two ships were designed to be improved versions of the and 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, 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.
