1941–1954 The seeds of the DLA were planted in World War II, when America's military needed to get vast amounts of munitions and supplies quickly. During the war, the military services began to coordinate more when it came to procurement, particularly of petroleum products, medical supplies, clothing, and other commodities. The main offices of the Army and Navy for each commodity were collocated. After the war, the call grew louder for more complete coordination throughout the whole field of supply—including storage, distribution, transportation, and other aspects of supply. In 1947, there were seven supply systems in the Army, plus an Air Technical Service Command, and 18 systems in the Navy, including the quartermaster of the Marine Corps. Passage of the National Security Act of 1947 prompted new efforts to eliminate duplication and overlap among the services in the supply area and laid the foundation for the eventual creation of a single integrated supply agency. The act created the Munitions Board, which began to reorganize these major supply categories into joint procurement agencies. Meanwhile, in 1949, the Commission on the Organization of the Executive Branch of the Government (Hoover Commission), a presidential commission headed by former President Herbert Hoover, recommended that the National Security Act be specifically amended so as to strengthen the authority of the Secretary of Defense so that he could integrate the organization and procedures of the various phases of supply in the military services. The Munitions Board was not as successful as hoped in eliminating duplication among the services in the supply area. Congress became disenchanted with the board, and in the Defense Cataloging and Standardization Act of 1952, transferred the board's functions to a new Defense Supply Management Agency. The Eisenhower Reorganization Plan Number 6 (1953) abolished both this agency and the Munitions Board, replacing them with a single executive, an Assistant Secretary of Defense for Supply and Logistics. Meanwhile, the Korean War led to several investigations by Congress of military supply management, which threatened to impose a common supply service on the military services from the outside. Integrated management began in 1958 with the formation of the Armed Forces Supply Support Center. For the first time, all the military services bought, stored, and issued items using a common nomenclature. The Defense Department and the services defined the material that would be managed on an integrated basis as "consumables", meaning supplies that are not repairable or
