"Shimakaze" was based on a lengthened version of the design, with an additional 25 feet of length to mount an additional quintuple torpedo launcher amidships.The additional weight caused the design to be top-heavy, so no torpedo reloads were carried; however, with a broadside of three quintuple mounts which could be trained to either port or starboard, "Shimakaze" had one of the largest torpedo capacities of any World War II destroyer.
