 that adopted the practical use teardrop type from the ship type for the first time in the Maritime Self-Defense Force in American naval forces at that time so far. When the Asashio class was built, the adoption of the teardrop type had been examined. However, the Maritime Self-Defense Force at that time selected the old model that valued safety from the operation results. It was moving to the warship type that valued the underwater performance, and the examination that used the model in 1960 fiscal year was advanced, and necessary data was obtained also with TRDI in the age.
