Ordered under the same programme as the previous class, the Asahi was a virtual repeat of that design, the major visual difference being that she only carried two funnels instead of the three in the previous class. This resulted from a re-arrangemem of the boiler rooms, which still encompassed 25 Belleville boilers. At first the machinery suffered from a number of minor faults and Asahi gained a reputation as a coal eater, but this was subsequently improved and the designed figures achieved. Internally the layout differed from the previous class, the watertight subdivision being improved with a total of 288 watertight compartments.
Main 76.2m belt was 2.5m high, its thickness amidships was 229mm (127mm at lower edge) decreasing consequently to 178 and 102mm near ship ends. It connected with main gun barbettes by 356-152mm bulkheads. Upper 66m belt was 152mm thick and 2.3m high. Casemates had 152mm face and 51mm rear armor. Barbettes had 356mm thickness over and 203mm under main deck. Turrets had 254mm faces, 203mm sides and rears and 102mm roofs. CT had 356mm sides and 76mm roof. 51mm armoured deck over citadel connected with lower edge of main belt by 102mm slopes. It had turtleback form outside barbettes and had 76-51mm thickness.
The active participant of the Russian-Japanese war. Badly damaged by Russian mine near Port Arthur 26.10.1904 and was under repair till April, 1905.
