Wartime Production World War II (1939-1945) had a drastic effect on automobile manufacturing in the United States. After 12 years of depression, high unemployment, and labor strife, America was attacked by the Japanese on December 7, 1941, at Pearl Harbor, Hawaii. Consequently, the United States entered World War II. Two months later, the last passenger car for the duration of the war rolled off the line. The automobile industry was converted to wartime production. Chrysler Corporation mass-produced tanks, and numerous carmakers built trucks for the military. GM built shells, bombs, fuses, navigation equipment, machine guns, artillery, and antiaircraft guns, in addition to engines and vehicles. Ford mass-produced bomber aircraft. The automakers more than doubled their productive capacity during the war, and women and minorities made up a significant portion of new workers. Next auuuu.com©2006.
