How would turbine-powered Lord Nelsons affect Dreadnought?
Short answerThey would probably push Dreadnought toward 24 knots and could encourage a superfiring arrangement.
NotesTurbines would probably raise the Lord Nelson class to roughly 21 knots and force Dreadnought toward 24 knots to preserve a meaningful speed advantage. Royal Navy design practice tended to bundle only a few major changes in one generation. If turbine propulsion is already proven in the preceding class, Dreadnought can spend more of its innovation budget on layout, fire control, or superfiring positions. Superfiring remains possible rather than certain, while the higher speed follows more directly from earlier machinery experience.
