Ship project history: Project was developed in days of the Russian-Japanese war and has anticipated "Dreadnought" occurrence: irrespective of British Japanese designers have come to the «all-big-gun» concept. Originally battleship should carry 12 305mms guns in four twin and four single turrets, however because of shortage of 12`` guns it was necessary to install intermediate 10`` guns. Satsuma became the first battleship built in Japan though 61% of her equipment, gears and materials have been received from abroad (mainly from UK). On trials ship was made 18.95kts at 18507hp power.
Ship protection: Thickness of main belt was 229mm between main gun barbettes, 152mm between fore barbette and stem and 102mm between aft barbette and stern. There was upper belt between main belt and casemate deck. Its thickness was 203mm between main gun barbettes decreasing fwd from fore barbette. Casemates were protected by 152mm armor. 51mm main deck connected with lower edge of main belt by 76mm slopes. 12`` turrets had 305mm faces and 203mm sides. CT had 305mm sides and 102mm roof.
Modernizations: 1916 - 1917: + 2 x 1 - 76/40 3-shiki AA
