Substantially identical to the previous ''Ikazuchi'' class, the main difference between the vessels was in the design of its
rudder

. With the previous class, the rudder was semi-balanced, and had a portion exposed above the waterline. This made the vessel vulnerable to disablement by stray gunfire. The ''Akatsuki'' class was intended to remedy this design flaw. Only two vessels were procured, as the Japanese navy intended to study the technique and to retrofit the existing ''Ikazuchi''-class vessels in Japan.
The design was similar to the four-
