Once Agincourt carries 18-inch guns, the alternate Hood also receives an 18-inch main battery. Its target speed rises to about 35 knots, and the main belt and turret armor are scaled upward for the heavier weapon. Larger guns bring heavier turrets and barbettes, while machinery and secondary armament still compete for displacement. Changing the main calibre reshapes the whole battlecruiser instead of producing a simple gun swap.
