Japanese B-65 Battlecruiser

[Karle94]

Probably it would have something similar to Iowa class

The design of the B-65's bow was more similar to the Agano or the Taiho imo.

Of course Dalamace, the bulbous bow of Yamato/Musashi was absolutely unique. Though the Germans (Bismarck/Tirpitz/Scharnhorst/Gneisenau), the Italians (Roma class) and the Americans (Missouri class etc.) had a so called "pear-shaped" bow or also called "drop shaped" bow (with slight differences per country), which was at least an improvement compared with the old fashioned bow. The Germans developed this bow type already in the 20ies and applied them to the steamers "Bremen" und "Europe". Also the "Taiho" had it, you mentioned it. But the bow of Yamato/Musashi was far ahead of its time as the discoveries of the wrecks revealed.

This style of bow was developed by Adm.Taylor and is team in the early 1900s. It was often referred to Taylors' bow. The first ship to be applied with a bulbous bow was the USS Delaware.
