A Soryu-derived German carrier and the British response

If Germany received Japanese carrier plans, how could it obtain a useful Graf Zeppelin?

A Soryu-derived design begun in 1934 could plausibly enter service by 1939, though Britain would respond by adding carrier construction of its own.

Soryu offered Germany a fast, capable design with a substantial air group and realistic range, unlike the compromised Ryujo. Its roughly 34-knot speed, useful endurance, and air group of more than sixty aircraft make it a credible starting point for a hull laid down after the design stabilized in 1934. German construction could therefore produce a serviceable carrier by 1939 if the project were managed coherently. The answer stresses that procurement does not occur in isolation: an early German carrier would likely prompt Britain to build another Ark Royal or accelerate its armored-carrier program.
