The gun elevation gear was improved to achieve a maximum rate of twelve degrees per second. The turrets were equipped with increased elevation limits versus their predecessors, 70 degrees in the Takao, Atago, and Chōkai, and 55 degrees in the Maya. After investigation of the recent County-class cruisers of the United Kingdom, it was decided to give the main battery some anti-aircraft ability. Three of the turrets were located before the bridge in a pyramidal distribution, with the other two aft of the main mast and aircraft handling facilities. Their main battery was ten 20.3 cm (8 in) guns in five twin mounts, for the first time the Mark 2 version of the gun was used during construction, all previous heavy cruisers received it during upgrades. The large tower bridge added to the instability, but the cause of much of the excess weight remains unclear, as many components were heavier than expected. This markedly reduced their freeboard and stability. However, like the Myōkōs, the Takaos ended up overweight, at 11,350 long tons (11,530 t). Like the Myōkō class, the ships were ostensibly intended to remain within the strictures of the Washington Naval Treaty, initially designed to weigh 9,850 long tons (10,010 t). The Takao class were an evolution from the preceding Myōkō class, with heavier torpedo armament and a large, almost battleship-like bridge structure. They all served during World War II.ĭescription United States Navy recognition drawings of Takao and Atago The Takao-class cruisers (高雄型) were a class of four heavy cruisers of the Imperial Japanese Navy (IJN) launched between May 1930 and April 1931. 16 torpedo tubes (4×4, with no reloads).8 × 20 cm/50 3rd Year Type No.2 naval guns (4x2).16 torpedo tubes (4×4, plus 8 reloads 24 Type 93 torpedoes).8 × 61 cm torpedo tubes (4×2, 24 Type 90 torpedoes).
