Background
On June 23, 2015, The Black Vault released a collection of declassified documents obtained through Freedom of Information Act (FOIA) requests concerning the Subterrene program. The documents describe a tunneling machine that utilizes nuclear heat to melt rock rather than excavating it, potentially leaving minimal trace of its passage. The publication includes technical specifications, military drilling applications, and references to autonomous underground monitoring systems. These disclosures provided documentary evidence supporting long-standing conspiracy theories regarding the existence of deeply buried military installations, specifically the alleged Dulce Base in New Mexico. The release demonstrated that while the Dulce Base remains unconfirmed legend, the technological capability to construct such facilities was actively researched by military contractors.
