 Nearly all the fleet's destroyers suffered damage to their superstructures, and fifty-four crewmen were lost, swept overboard or killed outright.The Japanese Admiralty held a hearing on the damage suffered by Fourth Fleet in the storm, resulting in recommendations for changes on Japanese warship design and construction.A number of new designs that used heavier guns and taller superstructures were found to be top heavy, and efforts were made to stabilize these ships by reducing weight above the waterline.
