Real Underground Tunnels, Cities, and Bases (DUMB’S) Video Documentary

Deep Underground Military Bases (DUMBs), along with extensive underground tunnels and facilities, are real and serve critical military and civilian purposes worldwide.

DUMB’s are made by some of the smartest people in the world. Ironic, right? Watch DUMB video documentaries below, and send to the friend who calls you a conspiracy theorist. Dont listen to America24, listen to DARPA themselves.

The Defense Advanced Research Projects Agency (DARPA), originally established as the Advanced Research Projects Agency (ARPA) on February 7, 1958, by President Dwight D. Eisenhower, is a research and development arm of the United States Department of Defense dedicated to pioneering breakthrough technologies for national security. It was created in direct response to the Soviet Union’s launch of Sputnik 1 in October 1957, which sparked fears of a “technological surprise” and highlighted America’s perceived lag in space and advanced military capabilities; the agency aimed to prevent future such shocks by driving high-risk, high-reward innovation far beyond immediate military needs, collaborating with academia, industry, and government partners.

Over the decades, DARPA has famously funded transformative projects like the ARPANET (the precursor to the modern Internet), stealth aircraft technology, GPS, advanced robotics, AI, and countless other advancements in areas such as materials science, cybersecurity, and biotechnology, while maintaining a lean, flexible “DARPA model” that relies on temporary program managers and short-term contracts rather than permanent labs or bureaucracy to foster radical, often revolutionary ideas that maintain U.S. military technological superiority.

The Cheyenne Mountain Complex (often referred to as the Cheyenne Mountain bunker or NORAD facility) is a fortified underground military installation carved deep into the granite of Cheyenne Mountain near Colorado Springs, Colorado.

Construction began in 1961 under the supervision of the United States Army Corps of Engineers, with excavation starting on May 18, 1961, and the facility becoming fully operational in February 1967 (with NORAD’s Combat Operations Center activating in 1966), at a cost of approximately $142.4 million. It was built primarily for the North American Aerospace Defense Command (NORAD), a joint U.S.-Canada organization established in 1958, to serve as a hardened command and control center capable of withstanding a direct nuclear attack from Soviet bombers or missiles during the height of the Cold War. The mountain’s solid granite structure, combined with engineering features like massive blast doors and shock-absorbing springs supporting the internal buildings, was designed to protect personnel, computers, and operations, ensuring continuous aerospace warning, air defense coordination, and survivability in the event of a nuclear exchange targeting North America.

These structures are engineered for protection against attacks, natural disasters, or to ensure operational continuity. Prominent U.S. examples include the Cheyenne Mountain Complex in Colorado, excavated deep beneath granite to house NORAD’s alternate command center with shock-mounted buildings, independent power, water, and air systems capable of withstanding massive blasts; the Raven Rock Mountain Complex (Site R) in Pennsylvania, often called the “Underground Pentagon,” which provides emergency operations for the Department of Defense and supports continuity of government; and the Mount Weather Emergency Operations Center in Virginia, managed for FEMA and designed as a high-security bunker for federal leadership during crises.

Military applications also extend to networks of underground missile silos, such as those at Minot Air Force Base in North Dakota for ICBMs, and vast tunnel systems like those in Gibraltar (built by the British military over centuries for defense and storage). On the civilian side, extensive underground infrastructure includes transportation tunnels, subways, utility networks, and emergency shelters, while some nations maintain large-scale subterranean facilities for strategic resilience, demonstrating that deep underground construction is a established engineering and defensive reality rather than speculation.

Inside DARPA’s SubT Challenge: Mapping the Unseen Underground

The DARPA Subterranean (SubT) Challenge Competitors’ Day was an informational event hosted by the Defense Advanced Research Projects Agency on September 27, 2018, in Louisville, Kentucky, to introduce the vision, timeline, and details of the upcoming DARPA Subterranean Challenge. Announced in July 2018, the event aimed to engage potential competitors, facilitate technical and operational exchanges, and encourage the formation of cross-cutting teams with diverse expertise in robotics, autonomy, and related fields to tackle the challenge of rapidly mapping, navigating, and searching complex underground environments—such as human-made tunnels, urban infrastructure, and natural cave networks—for applications benefiting warfighters and first responders. Registration for the Competitors’ Day opened on August 15, 2018, with advance sign-up required for on-site or virtual attendance, and the gathering provided preliminary information about the multi-year competition, which featured three circuit events and a final event in 2021, offering more than $3 million in total prizes across Systems and Virtual tracks.

Elon Musk’s Boring Company: Revolutionizing Underground Digging: “Tunnels & Roads to Beat Traffic”

Did the CIA and DARPA help Start The Boring company?

The Boring Company, founded by Elon Musk in 2017 (initially as a SpaceX subsidiary before spinning off independently in 2018), is an American infrastructure and tunnel construction firm dedicated to revolutionizing urban transportation by digging safe, fast, and low-cost underground tunnels to alleviate surface traffic congestion. Born from Musk’s frustration with Los Angeles gridlock—sparked by a 2016 tweet declaring he would “build a tunnel boring machine and just start digging”—the company aims to create multi-layered, 3D road networks using advanced tunnel boring machines (TBMs) like the Prufrock series, which promise dramatically faster and cheaper excavation than traditional methods. Its flagship operational system is the Vegas Loop in Las Vegas, a network of tunnels transporting passengers in Tesla vehicles (with over 3 million riders to date across stations connecting the Convention Center, resorts, and more), while ongoing or planned projects include expansions in Las Vegas, the Music City Loop in Nashville (with tunneling progress toward 2027 openings), a pilot Dubai Loop starting construction in late 2026, potential connections in Orlando for Universal theme parks, and various R&D tunnels. Though early visions included ultra-high-speed Hyperloop pods and ambitious inter-city links, the company has focused on practical, Tesla-driven urban loops to enable rapid point-to-point travel, minimize surface land use, and transform cities by making tunnels a viable alternative to above-ground congestion.
