Sunosaki-class combat support ship

The Sunosaki-class combat support ship (洲埼型給油艦) was a class of two support ships of the Imperial Japanese Navy (IJN), serving during World War II.

Construction
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
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.
