How much did large 8-inch cruisers take over from battlecruisers?
Short answerAlmost completely in the US Navy, while British Far East planning also shifted strongly toward cruisers.
NotesLarger 8-inch cruisers took over battlecruiser duties to different degrees in different navies. In the US Navy the substitution was nearly complete. In British planning, the Far East likewise became increasingly a cruiser war rather than a battlecruiser problem. Replacement followed geography and mission more than a universal change in ship labels.
