Cruiser categories without treaty tonnage ceilings

What cruiser types emerge if post-1915 development is not constrained by naval treaties?

A roughly 10,000-ton light cruiser and an 18,000-ton heavy cruiser, commonly armed with six-inch and 9.2-inch guns respectively.

Cruiser types could grow beyond the familiar treaty categories. The lighter type remains around 10,000 tons and favors six-inch guns for volume of fire, though eight-inch weapons are possible. The heavier type reaches roughly 18,000 tons and commonly carries 9.2-inch guns, with twelve-inch weapons an occasional upper-end choice. A British 9.2-inch cruiser gun would probably use a 50-calibre barrel. This creates a two-tier force based on mission and firepower rather than the Washington and London definitions.
