World War 2 pulled the US out of the Great Depression as the economy shifted to focus on wartime production. Various government agencies were established to direct industries to make military goods and manage supply shortages and price controls. Factories converted operations to produce airplanes, ships, weapons and ammunition. By 1945 the US had produced over 300,000 airplanes and other military equipment, becoming known as the "Arsenal of Democracy". Financing the war required increased taxes and sales of war bonds. Over 14 million women joined the workforce during the war to replace men serving in the military.
