Moving the Type 1936 screws closer to midships slightly improved the turning circle, but the ships remained difficult to control in a following sea. Their long, slow rolls made aiming and firing guns difficult. A torpedo boat could tolerate more rolling if its weapons entered the water safely and ran toward the target. A destroyer also had to defend other ships with accurate gunfire, which required a steadier platform. Screw, shaft and rudder arrangements therefore had to support aggressive torpedo maneuvers as well as controlled movements during defensive gunnery.

Why destroyers need a steady gun platform
The Type 1936's slow rolling exposed the different handling demands of torpedo attack and accurate defensive gunfire.
