Panama Canal passage is a hard design constraint. A narrower beam and reduced draft preserve mobility between the Atlantic and Pacific, but leave less room and displacement for guns, machinery, and protection. The proposed ship therefore combines canal-compatible dimensions with turbo-electric machinery and a 25-knot target, above the planned South Dakotas' 23 knots. Geography shapes the battleship before its combat qualities are tested.

Panama Canal limits shape the American concept
Panama Canal dimensions link beam and draft to the American battleship's speed, propulsion, armament, and protection.
