On December 7, 1941, the United States was attacked by Japan at Pearl Harbor.  The attack was a complete suprise to the citizens of the U.S.  The United States had begun a slow recovery from a the Great Depression.  In preparation for the war, the military ordered over 100 billion dollars worth of equipment in 1942.  The War Production Board didn't allow passenger cars to be manufactured, which allowed the available raw materials to be used for war materials (bullets/tanks/aircrafts/ships).  The government also created a national speed limit and gas rationing to conserve gas.  Farmers also played a role by increasing production.  Women played a vital role in factories as many men were drafted or enlisted to fight for the U.S.
