Another round, The 1930 Fujimoto designs:

This warship was designed by Captain Fujimoto to replace the Fuso class Battleship, and like the one designed by Hiraga (planned to replace the Kongo class) plans to build her where canceld with the ratification of the london naval treaty in 1931.

The first design called for a treaty battleship armed with nine 16.1-inch (409mm) guns in three triple turrets, secondaries where composed by twelve 6-inch (152mm) guns in six twin turrets, unusally fitted outside the armour belt and (at least the forward turrets) protected with a shield from blast damage from the main guns; 4 twin 5-inch (127mm) AA guns mounted on sponsons at the fore and aft end of the superstructure completed the armament.


The second one increased the main guns to twelve 16.1-inch (409mm) guns and moved 4 of the 6 twin 6-inch (152mm) guns inside the armoured citadel; given the heavy armament and dimension, with lenght exceding 260 meters this design will almost certainly had broken treaty limits if built.

One can't help but wonder just how effective those five inch guns would have been.
Nice drawing of a most unusual ship though

Source Materiel is always welcome.

Very unusual designs but also quite interesting. Kinda reminds me of the phrase in user experience design; designers aren't users, users aren't designers

Also those breakwaters forward are massive!

Awesome work, BB1987!

Actually those where not breakwaters but shields to protect the forward 6-inch guns from blast damage from the 16.1-inch guns. (don't know why there was no such thing aft tough...)

Ah I see. Rather interesting design decision in that case.

Splendid drawings but what about stability with those short hulls compared to the superstructure?

length has almost nothing to do with stability.

The IJN certainly entertained some entertaining ideas, if nothing else. One wonders about an exploding 6" magazine in service.
