The simulated success of the British design supports the expectation that continuous construction would encourage an all-forward fast-battleship doctrine. A navy would seek speed and firepower together rather than treating speed as a specialist battlecruiser attribute. The United States would then face a force-structure problem because its first treaty generation remained much slower. New fast ships and retained slow ships could create two battle lines with different tactical uses, while Britain would reduce the gap earlier through replacement.

Continuous building could split fast and slow battle lines
The scenario suggests that speed, armour and forward firepower would push later construction toward fast battleships while leaving older ships in a separate slow division.
