The War Production Board (WPB) was established in the United States during World War II to oversee the conversion of industries from peacetime to wartime production. Created in 1942, its primary goal was to ensure that the military had the necessary supplies and equipment, such as weapons and vehicles, to support the war effort. The WPB coordinated the production of materials and allocated resources to various industries. The WPB also played a crucial role in managing labor and controlling the distribution of raw materials. By prioritizing essential goods, the board helped streamline production processes and minimize waste. This organization was vital in mobilizing the American economy for the war, contributing significantly to the success of the Allied forces, including the efforts of the United States Army and Navy.
