Actual construction is the responsibility of the nation in whose territory a project is located. (c) Ownership and Status The figures in Table 3 show that on a cost basis more than four-fifths (83.1 percent) of the military real property controlled is located within the United States. Of the remainder, 3.7 percent is in the United States possessions and 13.2 percent in foreign countries. Of the world-wide increase during the year, 81 percent was in properties within the United States and its possessions. The distribution by military department of the world-wide military real property of the Department of Defense has continued to change slightly with the Air Force total moving up more rapidly than that of the other two military departments. A large part of this is accounted for by construction, which has been larger for the Air Force during recent years than for the other two military departments. As of one year ago, distribution of real property was 31.6 percent for Army, 30.4 percent for Navy and 38.0 percent for the Air Force. Distribution as of 30 June 1960 was 30.5 percent Army, 29.1 percent Navy and 40.4 percent Air Force. On a dollar cost basis, Air Force controlled the largest portion (36.0 percent) of the Department of Defense total within the United States, Navy has the largest part (56.5 percent) of properties in the United States possessions, and Air Force controls nearly three-fourths (70.7 percent) of the Defense total in foreign countries. It should be pointed out that from the standpoint of construction, Air Force installations are generally newer than those of either of the Army or Navy, and thus, their costs are generally more fairly representative of current value. Some of the facilities transferred to the Air Force, however, fall into the category of rather old structures for which original costs are not truly representative of current values. The cost of properties in non-industrial installations (training centers, depots, hospitals, command headquarters, ports, housing, etc.) were four-fifths of the cost of all properties on a world-wide basis. Reference to Table 8 shows that properties located at installations in an inactive or standby status on a world-wide basis cost $2.9 billion, 9.1 percent of all properties. This proportion in fiscal years 1959 and 1958 was 8.4 percent and 7.3 percent respectively. (d) Types of Properties Table 9 shows the military real property costs for the entire Department of Defense by broad geographical locations and by major facility groupings. Nearly one-fourth of the over-all total consists of utilities and ground improvements; this group is made up mainly of heat, power, water and sewer systems coupled with roads, bridges, walks and parking areas. Table 10 shows the ten categories of real property, listed in order of cost, in which the Department of Defense has the largest dollar investment. These data are illustrated in Chart 4. The ten categories on a world-wide basis represent a total cost of $20.1 billion or about two-thirds (62.8 percent) of the cost of all Defense-controlled real property.
