What happened in american factories during world war 2?

During World War II, more specifically after the attack on Pearl Harbor, American industrial production intensified, as a result of the increase in arms production and civilian supplies destined for combat forces.

More labor was needed for this, which in turn was scarce since many men were on the battlefront. Therefore, many industrial positions were occupied by women.

During the war, a peak of production was reached, which helped the United States to leave behind the Great Depression.
