The plans made North Dakota's turbines look likely to provide speed at the cost of cruising range. The comparison follows that period expectation forward, then checks it against the completed ships and their trial results. Mature technology did not guarantee the better outcome once design and construction moved from paper into a shipyard. Newport News failed to realize Delaware's expected advantage, while Fore River Shipyard at Quincy delivered a North Dakota that performed better than the plans implied. The divergence shows why design intent, contractor execution, and sea-trial evidence must be considered separately.

How completed ships can upset the paper comparison
Plans suggested that Delaware's mature triple-expansion machinery should out-range North Dakota, but the completed ships show how yard execution can overturn a logical paper forecast.
