How would the Radetzky class change if Britain introduced a fifteen-gun, 14-inch Dreadnought?
Short answerIt would probably remain close to the historical fast three-ship design, since matching Britain mattered less than preserving useful numbers and speed against Austria-Hungary's actual rivals.
NotesAustria-Hungary has several ways to react if HMS Dreadnought appears with five triple 14-inch turrets. One alternative is a slower design using four twin 12-inch turrets, but that choice falls toward 18 knots and abandons a key Radetzky objective. Retaining the roughly 21-knot mixed battery better suits the immediate planning problem posed by Italy and France rather than a direct battle with Britain. Enlarging the design might yield only two ships instead of three, weakening the local fleet even if each hull looked more modern on paper.
