How would Britain respond if Germany concentrated large-warship construction on a Scharnhorst pattern, including carriers?
Short answerBritain would probably build carriers and capital ships faster, while continued German use of 11-inch guns would give little reason to change the KGV's 14-inch armament.
NotesThe scenario concentrates German large-warship construction on a Scharnhorst-type design and includes aircraft carriers using Japanese practice as a model. With Scharnhorst and Gneisenau available by 1939, another batch might enter service in 1940, especially if construction alternated a capital ship with a carrier. That pace would probably accelerate British carrier and capital-ship construction. The German ships would likely retain 11-inch guns until their proposed 15-inch weapon was ready. Their appearance would create pressure for more British ships without necessarily changing the King George V class's 14-inch main armament.
