No adjustment in 1939 or 1940 could make Germany win a conventional naval war against Britain and its wider imperial partners. The Treaty of Versailles had broken the continuity of shipbuilding infrastructure, naval industry, and trained personnel on which a large fleet depended. Rebuilding required more than launching hulls: one trained generation had to operate the first ships and then prepare the next generation of crews and officers. A credible challenge would need an estimated thirty to forty years of institutional growth, making a 1950 war at least conceivable but a 1939 contest structurally unwinnable.

Why Germany could not build a war-winning fleet by 1939
The Treaty of Versailles left Germany without the industrial and personnel depth needed to create a fleet capable of defeating Britain on a 1939 timetable.
