American wartime destroyer output needs to be read against the smaller orders placed before the war. The comparison between 1938 and 1940 questions whether such a large increase reflected a suddenly new requirement. Earlier authorization and preparation affected what could be built once war began. Britain had already increased destroyer construction and carried out many V- and W-class conversions, although its preparation was also imperfect.

Why prewar preparation shaped destroyer output
American destroyer orders expanded sharply between the prewar period and 1940, while Britain had already increased building and converted older ships.
