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.

In operations, the two ships were all fights. Particularly active in the Solomon Islands, they participated in the “massacre” of the Savo Island, the night of August 8, 1942. The Kinugasa was sunk by a plane embarked on November 14, 1942 during the second battle of Guadalcanal, while the Aoba survived long enough to see his armament increase to 15 pieces AA 25 mm, then 42 two months later, in May-June 1944. He was also added a radar, while he lost one of his two banks of tubes launches -torpilles. He was at the Battle of the Coral Sea, at the first battle of Guadalcanal, at the second, and was finally wiped out by the raids of the 3rd US Air Fleet at the Kure Naval Base on July 25, 1945.
