Tone class and reconnaissance-cruiser compromise

The class was expected to provide reconnaissance so carriers could concentrate on strike missions, a requirement tied to Kantai Kessen assumptions. Its all-forward turret arrangement and aft aviation facilities made it a hybrid, but neither an especially strong cruiser nor an easy aircraft-support platform. A more radical division of labour would have paired strong conventional cruisers with merchant hulls designed for rapid conversion into seaplane carriers. Another proposed treaty workaround was a triple eight-inch turret installed initially without its centre gun, leaving a simpler path to later up-gunning. Recovering seaplanes forced the cruiser to stop or slow sharply, directly limiting the search radius that made reconnaissance valuable.
