Heavy, standard, and light shells are compared by armour-piercing range before the design retains a standard load instead of optimising one statistic. To combine 28 knots with roughly 13,000 kilometres of endurance, the virtual design's machinery rises from about 45,000 to 91,000 shaft horsepower and its cruising speed increases. The hull remains overweight and suffers serious pitch, forcing changes to the armour deck and internal protection. The exercise connects propulsion, fuel endurance, gunnery, protection, and seakeeping, showing why speed cannot be treated as an isolated requirement.

The propulsion cost of treaty-battleship speed and endurance
Shell-range choices, oceanic endurance, machinery power, excess weight, and pitch show how a 28-knot treaty battleship pays for speed throughout the rest of its design.
