Kitakami and Oi of this class are interesting in that they were taken in hand for modification as... torpedo boats on steroids (for want of a better designation). Kitakami was given 32 and Oi 40(!) x 24" tubes. These ships would have been very bad news in a night fight, but they spent most of their time up in the Aleutians, and so far as I know they never fired a shot from their tubes.
