The planned South Dakota class had an endurance of about 8,000 nautical miles at 10 knots. The game initially gives the alternate design roughly 20,791 kilometers at 25 knots, a much more demanding speed. That setting is reduced to about 15,000 kilometers to make the scenario less generous. The comparison shows why any quoted warship range needs its cruising speed and turns endurance into a design choice alongside armor, guns, and maximum speed.

A range figure only makes sense at a stated speed
The planned South Dakota class's 8,000-nautical-mile endurance at 10 knots provides a check on the alternate design's much faster range setting.
