Existing comment: Production Miracles:

In industry after industry Americans performed production miracles. One story helps capture the scale of the defense effort. In 1940 President Roosevelt shocked Congress when he proposed building 50,000 aircraft a year. In 1944 the nation made almost double that number. Ford's massive Willow Run bomber factory alone produced nearly one plane an hour by March 1944.

To achieve increases like this, defense spending jumped from $1.5 billion in 1940 to $81.5 billion in 1945. By 1944 America led the world in arms production, making more than enough to fill its military needs. At the same time, the United States was providing its allies in Great Britain and the Soviet Union with critically needed supplies.
