EARTH, Laniakea Supercluster—In a move that has electrified the UAP community, the whistleblower behind a controversial document presented to Congress last year has revealed his identity.

Matthew Brown, who claims to be a former U.S. defense and intelligence analyst, stepped forward in a recent three-part series on the Weaponized podcast with investigative journalists Jeremy Corbell and George Knapp. Brown is the author of the "Immaculate Constellation" report, which alleges the existence of a clandestine Pentagon program with the same name. According to Brown, this program gathers, analyzes, and conceals data related to Unidentified Anomalous Phenomena (UAPs) without congressional oversight, operating as an Unacknowledged Special Access Program (USAP) within the Department of Defense.

Brown explained his decision to go public in the first episode, acknowledging the risks to his personal life and career.

"I knew I was risking everything," he said.

He described "Immaculate Constellation" as a highly classified initiative that essentially quarantines information on UAPs, suggesting that only a select few within the government are aware of its existence.

The second episode explored Brown's attempts to report his findings through official channels, which he says were met with resistance. "I tried to follow the rules and the law by reporting what I had learned about this unacknowledged special access program called Immaculate Constellation," Brown recounted. He expressed frustration with the lack of response from his superiors, leading him to believe that the program operates without proper supervision.

In the final segment, Brown discussed the broader implications of UAP secrecy and urged others with knowledge to come forward. He warned that public perceptions about UAP issues are carefully managed. "Fear, greed, and willful ignorance are used as weapons by those who keep the secrets," he stated. Brown emphasized the importance of transparency and accountability in matters related to national security and UAPs.

The "Immaculate Constellation" Document

In November 2024, independent journalist Michael Shellenberger presented the anonymous document to Congress during a hearing titled "Unidentified Anomalous Phenomena: Exposing the Truth." Shellenberger described the document as coming from a whistleblower with direct knowledge of the program. He testified that the program consolidates UAP observations from various military and intelligence platforms, including infrared and full-motion video, serving as a central repository for this kind of data.

On the Weaponized podcast, Brown shared more details about his experiences and the contents of the "Immaculate Constellation" document. He discussed specific UAP encounters, including an incident where a saucer-shaped object appeared to react to satellite observation, suggesting it was aware of and evading surveillance.

Another startling event Brown described was a color photograph of a large black triangle floating above Russian naval ships in the Pacific Ocean. He called it a "collection incident," implying it was part of intelligence gathering activities. This photograph was reportedly found within a classified Pentagon wargame file. Brown initially thought it was a simulation but later identified it as part of the "Immaculate Constellation" program.

While the Department of Defense has denied the existence of the "Immaculate Constellation" program, stating that there is no record of it, the allegations have increased calls for greater transparency and oversight of UAP investigations. The presentation of the document to Congress and the subsequent public discussions highlight the controversies surrounding the UAP phenomenon and the government's role in investigating and disclosing information about it.
