30-Year Correlation of Sub-surface Infrastructure (DUMBs, Alien, and 'Black Budget' Facilities).
Underground Bases: The List
The scope of Underground Bases worldwide extends far beyond standard government installations. This directory is a master correlation of 30 years of data covering a vast spectrum of sub-surface facilities—ranging from known Deep Underground Military Bases (DUMBs) and continuity-of-government bunkers to suspected Alien Bases and advanced research laboratories that operate outside of public oversight. Whether these sites are utilized for clandestine military operations or involve non-human intelligence, they represent a hidden global infrastructure that the public is not meant to see
African Underground
The African continent holds some of the most ancient and least-documented subterranean anomalies. Research suggests that many Underground Bases in this region are tied to deep-crust mining operations that serve as fronts for much more complex, high-technology facilities. From the deserts of the north to the southern mining hubs, these sites are often characterized by extreme secrecy and strange seismic activity.
Asian Underground
Asia is home to some of the world’s most fortified subterranean networks. Many of these installations are rumored to be sprawling ‘underground cities’ capable of sustaining thousands of personnel. The data here points to a mix of heavy military fortification and areas of high-interest regarding non-human craft sightings near mountain-embedded facilities.
Central American Underground
The Underground Bases of Central America are often strategically positioned within dense jungle terrain or volcanic corridors. Investigations into this region suggest these facilities serve as high-security transit points for sensitive materials and anomalous cargo. Given the region’s complex topography, many of these sites are rumored to utilize ancient, pre-existing cavern systems that have been retrofitted with modern surveillance and ‘black budget’ defensive technologies.
Chinese Underground
The scale of Underground Bases in China is among the most massive on the planet. Our data indicates the existence of ‘Underground Great Walls’—vast subterranean complexes designed to house entire military divisions and advanced ballistic hardware. Beyond conventional defense, there are persistent reports of deep-level facilities in the high-altitude regions of Tibet and the Xinjiang deserts dedicated to reverse-engineering and non-human intelligence study.
European Underground
The Underground Bases of Europe are often built into the bedrock of ancient mountain ranges or hidden beneath historic military fortifications. Many of these sites were established during the Cold War for ‘Continuity of Government’ but have since evolved into high-security research centers. Data suggests these facilities are integral to a continental defense grid that monitors both terrestrial and sub-surface anomalies.

North American Underground
Canadian Underground
In the vast northern wilderness, Canadian Underground Bases are primarily located within the stable rock of the Canadian Shield. These facilities are often joint-operational sites, linked closely with North American aerospace defense. Researchers have identified suspicious activity in the Arctic regions, where extreme depth and sub-zero temperatures provide a natural thermal mask for facilities involved in deep-crust communications and clandestine energy experiments.”
Greenland Underground
Greenland serves as a desolate but vital frontier for Underground Bases. Historically known for ‘Project Iceworm,’ the region continues to be a focal point for deep-ice installations that operate far beneath the glacial surface. These sites are uniquely positioned for monitoring trans-polar activity and are frequently cited in reports involving ‘Other-Worldly’ craft emerging from the ice-covered coastal waters.
U.S. & Territories Underground
The United States and its territories maintain the highest density of documented Underground Bases in the world. This network spans from the highly publicized facilities in the Southwest to hidden ‘Continuity of Government’ bunkers beneath the capital and its surrounding territories. These installations represent a sophisticated hierarchy of Deep Underground Military Bases (DUMBs), biological research labs, and ‘Alien Bases’ where human and non-human interactions are rumored to take place under the strictest levels of classification.

Off World Bases
The discovery of Underground Bases is no longer restricted to Earth’s crust. Decades of satellite telemetry and whistleblower accounts from ‘Black Budget’ aerospace programs suggest a highly developed infrastructure of Off-World Bases across our solar system. On the Moon, research points to ancient subterranean ‘lava tubes’ repurposed for modern habitation, while on Mars, the focus shifts to massive, pressurized underground complexes designed for long-term personnel deployment. Beyond the inner planets, anomalous structures on the moons of Jupiter and Saturn, as well as mobile installations within the asteroid belt, suggest that the reach of these clandestine facilities is truly interplanetary. These sites represent the ultimate level of classification, operating as autonomous hubs for advanced technology and non-human interaction.
South American Underground
South America is a significant focal point for reports of ‘Other-Worldly’ Underground Bases, particularly in the Andes and the Amazon basin. These remote facilities are frequently associated with high-frequency aerial sightings and are rumored to be shared installations where military oversight provides cover for non-terrestrial biological entities (EBEs) and their operational craft.
The Poles Underground
The polar regions represent the most isolated and high-security frontiers for Underground Bases on the planet. Deep beneath the shifting ice of the Arctic and the ancient, multi-mile thick ice sheets of Antarctica, researchers have identified thermal anomalies and massive cavern systems that suggest active, self-sustaining installations. These facilities are often positioned near magnetic poles to leverage unique geophysical properties for advanced propulsion and communication experiments. From the rumored ‘Entrance at the Pole’ to documented ‘Continuity of Government’ bunkers like the Svalbard seed vault, the Underground Bases at the Earth’s extremities serve as a final stronghold for the world’s most classified ‘black budget’ projects and potential non-human outposts.
Oceania Underground
The Oceania region, anchored by the vast Australian outback, provides one of the most strategically isolated environments for Underground Bases on the planet. Our research indicates that the Australian mainland is home to high-level joint-defense facilities, such as Pine Gap, which extend miles into the ancient subterranean crust to facilitate deep-space surveillance and ‘black budget’ communications. Throughout the surrounding Pacific islands, these facilities often transition into sub-aquatic installations, utilizing volcanic atolls and undersea ridges to mask the movement of craft. Whether built for signals intelligence or to house non-human assets, the Underground Bases in this sector represent a critical node in the global surveillance and defense grid.
Russia & The Siberian Underground
The vast and unforgiving landscape of Russia and the Siberian interior hides some of the world’s most sophisticated and deepest Underground Bases. From the legendary Mount Yamantau complex—believed to be a massive, self-sustaining underground city—to the remote research stations of the Tunguska region, these facilities are designed for absolute survival and high-level ‘black budget’ operations. Our data suggests that the Russian Federation has maintained and expanded upon Soviet-era subterranean infrastructure, focusing on deep-crust energy harvesting and the study of anomalous activity in the permafrost zones. These Underground Bases are characterized by their extreme depth and their strategic placement in geologically stable regions, far from the prying eyes of international satellites.
Mapping the world’s Underground Bases is a monumental task that involves sifting through decades of disinformation. While our list is extensive, it is by no means complete. The architectural signatures of these bases—whether they are human-made military bunkers or something far more ‘other-worldly’—require constant vigilance and new data to verify.
