Would G3 and N3 have changed German naval rearmament?

Would completed G3 and N3 classes have pushed Germany toward a more sensible capital-ship program?

Probably not: prestige and gun-size politics would still encourage an attempted response, while faster British treaty designs could have made early German surface losses more likely.

The British designs would not automatically have produced a restrained German fleet. Dictatorship, prestige, and a political fixation on very large guns could override a balanced assessment of resources. Operationally, an F3-type ship could also have maintained contact with Scharnhorst where Rodney could not, making a German loss more plausible. Losing such a ship early might then have changed the assumptions behind later sorties, including the confidence attached to Bismarck. The answer separates rational procurement pressure from the political system that would have interpreted it.
