The Domestic Minerals Program Extension Act of 1953 sought to reduce American dependence on overseas sources of supply for strategic or critical minerals and metals during periods of threatening world conflict.[272] This was to be accomplished through a united effort on the part of each department and agency of the government having responsibility for the discovery, development, production, and acquisition of strategic or critical minerals and metals in order to decrease further and to eliminate where possible the dependency of the United States on overseas sources of supply of each such material.[273] The Act extended for an additional two years the termination dates of all purchase programs designed to stimulate the domestic production of tungsten, manganese, chromite, mica, asbestos, beryl, and columbium-tantalum-bearing ores and concentrates and established by regulations issued pursuant to the Defense Production Act of 1950.[274] MILITARY SITES AND PRODUCTIVE FACILITIES Scattered through the statute books, of course, are numerous authorizations to defense agencies to acquire land for specific projects. For example, a July 1939 statute authorized the Secretary of War to acquire fourteen described plots,[275] and a May 1949 statute authorized the Secretary of the Air Force to establish a joint long-range proving ground for guided missiles and other weapons and to acquire lands and rights necessary to set up the project.[276] An Act of 1951 authorized the Secretary of the Navy to enlarge existing water-supply facilities for the San Diego, California area for the purpose of insuring the existence of an adequate water supply for naval installations and defense production plants in that area.[277] Of equal, if not greater significance than the scope of the delegation contained therein are the provisions for extension of Congressional control set-out in these authorizations for acquisition of specific items. In the Second War Powers Act, breadth of Congressional delegation rather than intensity of control is the dominant fact. For example, the President was authorized to permit the Secretaries of War and Navy, or any other officer, board or commission, to acquire real property by any means necessary, including condemnation, to insure its use by the Government when needed.[278] Immediate possession might be taken after filing of a condemnation petition.[279] Among the many powers granted to the Federal Civil Defense Administrator in the 1951 statute creating the FCDA was that of procuring by condemnation or otherwise, constructing, or leasing materials and facilities.[280]
