Visualizing a late-1920s F3 development

The design demonstration translates the treaty argument into a plausible late-1920s F3 development of roughly 40,000-42,000 tons standard displacement. Nine improved 15-inch guns provide the main battery, while a 14-inch belt gives the ship substantial protection for a battlecruiser. The proposed 5.5-inch dual-purpose weapons replace separate anti-ship and anti-aircraft secondary batteries, saving weight and encouraging an earlier British dual-purpose doctrine. The game model also illustrates the Royal Navy's likely caution toward quadruple turrets after only recently accepting triples. Its quick victory is a visualization rather than proof, but the model shows the hull proportions, armament arrangement, and intended tactical character of the hypothetical ship.
