Construction

edit

In 1939, the IJN planned two support ship classes to help their aircraft carriers. One was the 8,000-ton Ashizuri class, the other one the 4,500 ton Sunosaki class. The Sunosaki was planned to support for two medium-sized carriers (Sōryū and Hiryū) in the battlefield. The thought is the same as USS Sacramento.

Service

edit

The Sunosaki class was unable to support Japan's carrier task force, because their commissions were delayed. They sailed between the Japanese mainland and Southeast Asia, and were lost before participating in a naval battle.
