How much did larger cruisers take over battlecruiser duties?
Short answerAlmost completely in the United States Navy, while Britain relied on cruisers routinely in the Far East but still used battlecruisers for exceptional heavy response.
NotesThe answer differs by navy. Heavy cruisers largely absorbed the role in the United States Navy, whose strategic needs differed from Britain's. In the Royal Navy, the Far East became predominantly a cruiser theater, with battlecruisers appearing when a heavier rapid response was required. Replacement came through a redistribution of missions rather than a single date when one type made another irrelevant.
