s. 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 design of the three-boilered ''Murakumo''-class destroyers had been similar to that of the two-

The bridge and forward gun platform were barely raised above the bow, resulting in a wet conning position. More than half of the small hull was occupied by the boilers and the engine room. With fuel and weaponry, there was little space left for crew quarters, although slightly more than in the ''Murakumo'' class. All were powered by triple expansion steam engines for and had
