Aircraft facilities

There were 4 catapults. Seaplanes based on deck and in hangar. There were 2 lifts. 8 additional seaplanes carried as reserve. Aircraft fuel stowage was 900 t.

Project history

Design was created on the basis of drawings of seaplane tenders of Chitose class, ship was built under 3rd Supplementary Programme of 1937. Main differences concerned machinery structure: instead of combined diesel-turbine, installed on a prototype, Mizuho have been equipped by only diesels. Though it has called appreciable decrease in a speed, it was possible to increase hangar size, having prolonged it fwd. The number of carried spare seaplanes has increased to 8. A hinged platform as that on Mizuho was not, and pairs of pylons were connected among themselves by bridges.
