Did you know that the US has well over 120 DUMBs (Deep Underground Military Bases)? They are mainly situated under MAJOR cities, and for years, the one I was most familiar with the Denver’s Airport. These DUMBs include United States Air Force Bases, Navy Bases, Army bases, FEMA Military Training Camps and DHS control centers …. all buried under the earth’s surface.
DUMBs aren’t confined to the United States, these seem to be worldwide, though I don’t know that they are in every country. The majority of these bases are over two miles underground and diameters range from ten miles up to thirty miles across. Impressive sounding, but also kinda sci-fi sounding, too, isn’t it?
