Model (scale 1:48). The succes of armoured floating batteries in 1855 led to the French developing an armoured type of sea-going frigate. The British followed with the construction of the 'Warrior', the first iron-built and armoured warship. Built at Blackwall from designs by Sir Isaac Watts, she was 380 ft long with a displacement of 9210 tons. Her side armour consisted of belts of iron plates 4.5 ins thick, backed by 18 ins of teak planking. In 1867, her armament consisted of four 8-inch guns and 28 7-inch guns. When she entered service, HMS Warrior could outrun and outgun any other ship then afloat.
