Would a modernized American battleship still carry torpedo tubes by the Second World War?
Short answerNo. The torpedo tubes would have been removed by then, freeing weight for more useful modern equipment.
NotesAmerican battleships no longer carried torpedo tubes by the Second World War, so the modernization removes them. Keeping the tubes would preserve an earlier capital-ship feature with little place in the later design. Their removal releases about one hundred tons, which can support additional five-inch guns or other modern equipment. A plausible refit depends on stripping obsolete systems as well as adding new ones.
