Spare torpedoes are stored behind the tube in racks.
Cruisers
Aoba and
Kinugasa originally should repeat
Furutaka class, however under Naval Staff insisting a number of changes had been brought into the project, to the main things from which was transition from single to twin main gun turrets and more traditional scheme of placing of artillery. Besides, instead of 76mm AA guns new 120mm were installed, and between an aft superstructure and turret there was a catapult for seaplanes. By calculations, displacement should increase approximately on 360t. At a phase of working out of the project designer still knew nothing about a menacing overload of
Furutaka class also any measures for correction of this position by the new ships were not been undertaken. Excess of design displacement of completed
Aoba and
Kinugasa on 1000t (standard under the project was 8760t, actual on
Kinugasa was 9773t) became a result of ignoring of weighting discipline (and, probably, and errors in calculations). Heavier, than by the ships of the previous class, armament have led to additionaal stability decrease.
In 1938-1940 both cruisers have passed modernization in which course 200mm guns have replaced by more powerful 203mm.
Fixed 610mm TT were replaced by 2 quadruple trainable mounts with complete set of spare torpedoes. Ships were equipped also with more powerful catapult. Planned replacement of boilers on a number reasons have refused, having limited to transfer of boilers from mixed fuel to purely oil. After entering of some improvements to turbines engine power has raised from 102000 to 110000hp. For stability preservation at the increased weight of armament cruisers received bulges that have made them on 0.7m more widely, than predecessors.
Thường thì mỗi trận nó chỉ xài đống torp có sẵn trong tube thôi vì thời gian nạp lại khá lâu vì phải dùng cần cẩu linh tinh...
