The United States ensured that materials needed at the front were produced by implementing the War Production Board (WPB), which coordinated industrial production and prioritized resources for military needs. Factories were converted to produce war materials, and the government established contracts with private companies to manufacture everything from weapons to vehicles. Additionally, the Office of Price Administration controlled prices and rationed materials to prevent shortages and manage consumer demand, ensuring a steady supply for the military.
