How many 12-inch mini-Renown cruisers would the Royal Navy seek?
Short answerIt might desire roughly a dozen, but the strategically meaningful number is how many are built and operational before war begins.
NotesThe closing answer restates a central theme of the stream: wishes do not win battles, and programs do not create capability until ships exist and work. Force planning must therefore distinguish aspiration from deployable reality. A requirement for roughly twelve ships says little about how many yards, budgets, and years will actually deliver before a crisis. Readiness then narrows the completed force again to the hulls that can sail and fight.
