History and Formation

The ASF was established in 1942 amid reorganization driven by leaders including Franklin D. Roosevelt, Harry S. Truman, George C. Marshall, and Henry L. Stimson. Its creation followed debates involving offices such as the War Department and the Office of the Chief of Staff and was influenced by earlier logistics efforts in the First World War and innovations from the Interwar Period. The ASF absorbed functions from entities such as the Services of Supply (SOS) and worked with civilian agencies like the War Production Board and the Office of Strategic Services to streamline supply, procurement, and transportation during the Entry of the United States into World War II.
