Most importantly, by the end of 1943 the United States had mobilized fully for war both in Asia and in Europe. In the year to come, the United States would produce 300,000 military planes and 529 large warships. Germany’s production was 133,000 and 20; Japan’s, 70,000 and 90. In the first three months of 1943 the United States produced as much overall shipping tonnage as Japan did in total during seven years of war. The Soviet Union was on the offensive in Europe, but the country itself was devastated. The United States was untouched, and its GDP had almost doubled since 1939.
