The Sōsato-class battleships were a class of super-dreadnought battleships built for the Imperial Taoist Navy (ITN) during World War I. While two the ships did not enter service until the end of World War I, they both saw extensive service in World War II.

Design

In 1934 both ships underwent a massive rebuild and refit to modernize the very outdated ships. The largest inclusions to the refit were basic radar systems and much improved fire control systems. The biggest visual difference in the refit was the addition of the pagoda-style superstructures, which were added to allow for more space for command rooms, as well as the aforementioned radar and FCS systems. Another major benefit to the pagoda masts was the ability to mount many anti-aircraft weapons, which would soon prove useful in the upcoming World War II.
