The Oyodo class was a group of four cruisers to be built under the War builds supplements. Only the lead ship of the class was built as a cruiser, the other three were repurposed as light carriers (CVL) of the Nisshin class. The only reason this ship was completed as a cruiser was the ship was considered to far in its building cycle to be altered.
For the first time in a Japanese cruiser, no torpedoes were fitted. The aircraft facilities took precedence with this ship as it would act as a destroyer leader to the Akizuki class destroyers. The 3.9" weapons were in open backed twin mountings. They did not fire as fast as the twin turrets but were still a very handy weapon. The armoured belt was only outside the machinery spaces, the magazines had 2" of box armour around them.
Note the 3.9" at high elevation.
