In conspiracy theory,
Deep Underground Military Bases (or D.U.M.B.s) are exactly what their name implies: secret underground bases built by the US military (via private military contractors) at exceptionally
deep strata.
In past
human history, we find accounts of ancient tunnels in
Arizona built by the fabled “Ant People” of Hopi lore. We also read about the famous
Nazi bunker of Adolf
Hitler's final days —an exceptionally engineered bunker with bedrooms, offices, dining facilities, and environmental controls. It is speculated that
Nazi scientists from Operation Paperclip were crucial for the success in engineering the first American D.U.M.B.s in the 1950s and 1960s, including the Cheyenne Mountain Complex (now part of the US Space Force).
According to witnesses, D.U.M.B.s exist all over the
United States, with the heaviest concentration beneath the High Desert of the American West where the rock strata is strong enough to support the structures, and the lack of groundwater affords the least interference from flooding during construction, expansion, and ongoing operations.
Privately contracted long haul truckers claim underground highways connect these bases, stretching through tunnels for many hundreds of miles, complete with intersections, traffic lights, and gas stations.
FEMA's "Continuity of
Government" initiative is rumored to include D.U.M.B.s in its plans to preserve key governmental personnel in the event of a catastrophic national emergency, such as nuclear war.
The US military has secretly built hundreds of
Deep Underground Military Bases (aka D.U.M.
B.s) all across the
USA, especially in the American West, and Antarctica is said to have one of the largest singular, self-contained D.U.M.B.s in the world.
