The turbines were rated at a total of 52000shp for a designed speed of 35kn. The ships had a range of 5000nmi at a speed of .[3]
The main armament of the Kagerō class consisted of six Type 3 1271NaN1 guns in three twin-gun turrets, one superfiring pair aft and one turret forward of the superstructure.
