Furthermore, Taisho 12, (1923).
The imperial navy started the design of a 10,000t class of a battle cruiser based on the shipbuilding theory of Mr.Hiraga.
(A battle cruiser 10,000t or more cannot be built those days because of the Washington Convention)
And the No. 1 ship of a treaty type battle cruiser was named 'Nachi'.
The main guns are 20cm. (two guns in a gun turret)
They are three set turrets to a bow and two set turrets to a stern.have been arranged. Main guns of a total of 10 .
This full equipment captured the spotlight of the navy of other country.
In the case of 'Nachi' ,
Since three turrets of the main guns had been arranged to a bow, hence, the position of the bridge came on the boiler room.
Then, the big box was placed on the smoke pass, the support was stood on this, and the bridge has been arranged.
This is a model of a ship which is not looked by other navies. The speed of 'Nachi' was designed by 35.5 kts.
(quicker 1.0 kts than Furutaka)
However, a cruising range is 7,000 nautical miles (fuel is 2,500tons) in 14kt(s).
It was a battle cruiser with a short cruising range.
This was the fundamental plan of the imperial navy.
