It seems like Japanese Tone-class cruisers carried multiple models of floatplanes on the same ship. Were different models assigned to different tasks, or was it just a matter of what was available or ???
First off, welcome to the circus!
Cruisers carried one or both of a Aichi E13A “Jake” and a Nakajima E8N “Dave”. The “Dave” was a relatively short-range (480 nm) open-cockpit two-seater, the “Jake” much longer range (1,100 nm) closed-cockpit three-seater. The “Jake” could carry more bomb-weight, but both planes were intended for reconaissance (a “Jake” reconned Pearl Harbor before the attack there.)
Hope this helps!
