Was there a role for a new Royal Navy eight- or 9.2-inch cruiser in the 1940s and early postwar period?
Short answerYes; a 9.2-inch cruiser could provide the heavy hitting power, carrier escort, and presence absent from Britain's mainly six-inch cruiser fleet.
NotesA new 9.2-inch British cruiser could fill a useful role from the 1940s into the early postwar period. Six-inch Town- and Arethusa-class cruisers cover important long- and short-range work, but neither provides a next-generation heavy cruiser able to dominate other cruisers. Once Britain stops building battleships, a larger gun cruiser also supplies visible presence and heavy surface support for carrier groups. The proposed caliber would add a limited number of ships able to punch above the existing cruiser force without replacing every cruiser.
