§ 9773. Acquisition and construction: installations and depots
(a) The Secretary of the Air Force shall determine the sites of such additional permanent Air Force and Space Force military installations and depots in all strategic areas of the United States and the Commonwealths, possessions, and holdings as he considers necessary. He shall determine when the enlargement of existing installations and depots is necessary for the effective peacetime training of the Air Force or the Space Force.
(b) In determining the sites of new installations and depots, the Secretary shall consider the following regions for the purposes indicated—
(1) the Atlantic northeast, for training in cold weather and in fog;
(2) the Atlantic southeast and Caribbean areas, for training in long-range operations, especially those incident to reinforcing the defenses of the Panama Canal;
(3) the southeastern United States, to provide a depot necessary to maintain the Air Force;
(4) the Pacific northwest, to establish and maintain air communication with Alaska;
(5) Alaska, for training under conditions of extreme cold;
(6) the Rocky Mountain area, to provide a depot necessary to maintain the Air Force, and for training in operations from fields in high altitudes; and
(7) other regions, for the establishment of intermediate installations to provide for transcontinental movements of the Air Force or Space Force for maneuvers.
(c) In selecting sites for installations and depots covered by this section and in determining the alteration or enlargement of existing installations or depots, the Secretary shall consider the need—
(1) to form the nucleus for concentration of Air Force or Space Force units in time of war;
(2) to permit, in time of peace, training and effective planning in each strategic area for the use and expansion of commercial, municipal, and private flying installations in time of war;
(3) to locate, in each strategic area in which it is considered necessary, adequate storage facilities for munitions and other articles necessary to facilitate the movement, concentration, maintenance, and operation of the Air Force or the Space Force; and
(4) to afford the maximum warning against surprise attack by enemy aircraft upon aviation of the United States and its necessary installations consistent with maintaining, in connection with existing or contemplated landing fields, the full power of the Air Force or the Space Force for operations necessary in the defense of the United States, and in the defense and reinforcement of the Commonwealths, possessions, and holdings.
(d) In carrying out this section, the Secretary, on behalf of the United States, may acquire title, in fee simple and free of encumbrance, to any land that he considers necessary—
(1) by accepting title without cost to the United States;
(2) by exchanging military reservations or parts thereof for that land, upon the written approval of the President; or
(3) by purchase or condemnation, if acquisition by gift or exchange is impracticable.
(e) The Secretary may, by purchase, gift, lease, or otherwise, acquire at desired locations bombing and machine gun ranges necessary for practice by, and the training of, tactical units.
(f) At each installation or depot established under this section, the Secretary shall remove or remodel existing structures as necessary; do necessary grading; and provide buildings, utilities, communication systems, landing fields and mats, roads, walks, aprons, docks, runways, facilities for the storage and distribution of ammunition, fuel, oil, necessary protection against bombs, and all appurtenances to the foregoing.
(g) The Secretary may direct the transportation of personnel, and the purchase, renovation, and transportation of material, that he considers necessary to carry out this section.
