In determining the locations of new stations and depots, consideration shall be given to the following regions for the respective purposes indicated: (1) The Atlantic Northeast-to provide for training in cold weather and in fog; (2) the Atlantic Southeast and Caribbean areas—to permit training in long-range operations, especially those incident to reinforcing the Panama Canal; (3) the Southeastern States-to provide a depot essential to the maintenance of the General Headquarters 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 essential to the maintenance of the General Headquarters Air Force, and to afford, in addition, opportunity for training in operations from fields in high altitudes; and (7) such intermediate stations as will provide for transcontinental movements incident to the concentration of the General Headquarters Air Force for maneuvers. In the selection of sites for new permanent Air Corps stations and depots and in the determination of the existing stations and depots to be enlarged and/or altered, the Secretary of War shall give consideration to the following requirements: First. The stations shall be suitably located to form the nucleus of the set-up for concentrations of General Headquarters Air Force units in war and to permit, in peace, training and effective planning, by responsible personnel in each strategic area, for the utilization and expansion, in war, of commercial, municipal, and private flying installations. Second. In each strategic area deemed necessary there shall be provided adequate storage facilities for munitions and other essentials to facilitate effective movements, concentrations, maintenance, and operations of the General Headquarters Air Force in peace and in war. Third. The stations and depots shall be located with a view to affording the maximum warning against surprise attack by enemy aircraft upon our own aviation and its essential installations consistent with maintaining, in connection with existing or contemplated additional landing fields, the full power of the General Headquarters Air Force for such close and distant operations over land and sea as may be required in the defense of the continental United States and in the defense and the reinforcement of our overseas possessions and holdings.
