Aoba class cruisers (1926)
Japan, 1926. Heavy Cruisers Aoba, Kinugasa
The Improved Furutaka
The two heavy cruisers of the Aoba class followed the Furutaka a year apart, so that their development did not take into account the defects of the two previous ships. They had from the start three double turrets and AA parts of 120 mm. On the other hand their tubes were always in six groups of two on the flanks. A first modification intervenes in 1932: They received 8 machine guns of 13.2 mm in reinforcement. In 1938-40, their fixed tubes were replaced by two quadruple rotating benches on the deck, while they were equipped with lateral ballasts. Their DCA was reinforced with 25mm guns and another four heavy machine guns, bringing the total to 12.
