Nine 16-inch Scharnhorsts would trigger a larger British battleship program

What happens if Germany tries to build nine Scharnhorst-class ships with six 16-inch guns each?

The long, visible buildup prompts Britain to field 16-inch King George V and Lion-class ships in greater numbers, leaving Germany behind despite its stronger fleet.

Germany could not produce nine 16-inch Scharnhorst-type ships by simply repeating the historical program. Heavy-gun development and yard expansion would have to begin around 1931-34, while three building streams displaced carriers, Bismarcks, and other work. That visible effort would reach British planners before the King George V design was fixed. Britain would probably choose 16-inch ships and use its larger industrial base to build roughly two counters for each German unit, followed by carriers and Lions. Germany gains a stronger surface fleet, but it also provokes a response beyond its ability to match. Any arms-race counterfactual must include the opponent's production decisions.
