What would an Iowa-era equivalent of the cheaper R class look like?
Short answerIt would keep Iowa's guns but fall to about 28 knots, use a shorter hull, and emphasize subdivision and protection over high speed.
NotesThe question uses the R class as a cheaper counterpart to Queen Elizabeth and asks for the same relationship to Iowa. North Carolina and South Dakota are offered as partial comparisons, with the panel criticizing the compromises imposed by South Dakota's cramped arrangement. The new proposal keeps Iowa's guns while reducing speed to about 28 knots. It would shorten the elongated hull and favor subdivision and protection over the high-speed form. The result is conceived as a standard battle-line ship, and remains an outline counterfactual rather than a worked design.
