Newly declassified Pentagon documents reveal that aerospace contractor Bigelow Aerospace developed architectural plans in 2009 for a heavily fortified 5,000-square-foot underground vault designed to store recovered hardware and biological specimens related to UAP investigations. The facility, never publicly disclosed until now, featured reinforced concrete walls three feet thick and was meant to be buried 15-20 feet underground at Bigelow's North Las Vegas operations, with plans to acquire exotic materials from private individuals and international sources including Brazil.
Pentagon documents released on October 23, 2026, as part of the seventh batch of the Presidential Unsealing and Reporting System for UAP Encounters (PURSUE) reveal extensive plans by Bigelow Aerospace Advanced Space Studies (BAASS) to construct a secret underground vault specifically designed to house recovered hardware and biological material related to unidentified anomalous phenomena investigations. The 5,000-square-foot facility, detailed in a 134-page June 2009 report designated DOW-UAP-D171, represents one of the most substantial evidence of institutional preparation for potential UAP material acquisition by a Pentagon-contracted private aerospace firm during the Advanced Aerospace Weapons System Applications Program (AAWSAP).
The proposed vault structure embodied extraordinary security measures unusual for a scientific research facility. According to the declassified document, the underground complex was to feature three-foot-thick reinforced concrete walls, floors, and ceilings, buried between 15 and 20 feet beneath the surface at Bigelow's North Las Vegas facility. The design incorporated multiple security barriers, armed guard positions, extensive camouflage of any visible entrance or above-ground features, and controlled access protocols typical of Department of Defense classified storage installations. The specifications suggest the facility was intended to contain materials of extraordinary sensitivity and potential national security implications.
The report's most revealing section outlines BAASS's active acquisition strategy for obtaining exotic materials from external sources. Administrators explicitly stated the organization was pursuing recovered hardware and biological samples held by private companies, individual collectors, and international research groups outside United States borders. Brazil was specifically identified as a priority acquisition location. This strategy indicates BAASS officials anticipated obtaining anomalous materials through non-governmental channels, suggesting either incomplete confidence in official government recovery programs or deliberate efforts to supplement Pentagon holdings through private procurement networks.
The architects of the BAASS vault acknowledged that existing facilities at the Bigelow Aerospace complex in North Las Vegas lacked adequate security infrastructure to properly store unusual biological specimens or exotic materials should they become available. This assessment led to the design of the purpose-built underground structure—a far more robust solution than standard laboratory or warehouse facilities. The emphasis on specialized biological specimen storage alongside recovered hardware suggests planners anticipated receiving materials of both technological and biological origins, consistent with whistleblower accounts of recovered non-human beings alongside craft components.
Bigelow Aerospace's BAASS operated from 2008 to 2010 under a Defense Intelligence Agency contract initially valued at $10 million, conducting what officials designated as studies of aerospace threat assessments and advanced technologies. However, internally the organization investigated a broad spectrum of unexplained phenomena, paranormal activity, and alleged UAP crash retrieval cases. The organization's headquarters at the North Las Vegas facility served as the operational center, while related investigations occurred at Bigelow's Skinwalker Ranch property in Utah, acquired specifically for UAP research purposes. The DIA contract itself contained no explicit mention of UFO investigations, maintaining classified compartmentalization.
The vault blueprint remained entirely undisclosed to the public until the October 2026 PURSUE release, despite references in some investigative journalism circles to secure storage modifications at Bigelow facilities. Previous news reports had mentioned modified buildings and secure compartmentalization but did not specify the underground vault's existence or sophisticated design specifications. Robert Bigelow himself publicly denied housing recovered material in interviews with investigative journalists, stating in one notable MysteryWire exchange: "We never had any." The declassified document provides no evidence the vault was ever constructed or utilized, but its very existence in official Pentagon records suggests serious contingency planning for material reception and storage.
The PURSUE batch 7 release of this document occurs amid broader Pentagon transparency initiatives under the Trump administration's direct order to declassify UAP-related records. The inclusion of 17-year-old BAASS facility plans raises questions about what other contractor infrastructure, acquisition protocols, and material handling procedures remain classified or undisclosed. The document adds substantive detail to longstanding claims by UAP researchers and former intelligence officials that private aerospace contractors have been positioned as potential custodians of recovered anomalous materials, with purpose-built facilities designed to secure and study such specimens.
Pentagon spokesman Sean Parnell stated in late October that the Department of War remains actively working on additional PURSUE file releases on a rolling basis. Whether subsequent releases will include documentation of vault construction, operational records, or acquisition activities remains uncertain. The revelation also provides historical context for present-day debates about institutional authority to receive, store, and analyze potential UAP materials, particularly regarding the role of private contractors versus government agencies. As disclosure progresses, researchers and lawmakers have intensified pressure for clarification on whether similar security infrastructure exists at other contractor facilities or government installations.
