Immaculate Constellation: Pentagon Secret UAP Program Explained

On November 13, 2024, independent journalist Michael Shellenberger stood before the U.S. House Oversight Committee and placed a 12-page document into the congressional record. The report, written by a current or former U.S. government official with direct access to classified programs, described an active Department of Defense Unacknowledged Special Access Program known as Immaculate Constellation.

According to the document, Immaculate Constellation functions as a central repository and coordination hub for high-quality imagery intelligence (IMINT) and measurement and signature intelligence (MASINT) related to Unidentified Anomalous Phenomena. It allegedly consolidates data from both tasked and untasked collection platforms across the Department of Defense and intelligence community.

The timing of the disclosure was deliberate. It occurred during a hearing titled “Unidentified Anomalous Phenomena: Exposing the Truth,” at a moment when public and congressional pressure for greater transparency on UAP was intensifying. The report claimed that the executive branch had managed certain UAP and potential Non-Human Intelligence (NHI) issues for years without meaningful congressional oversight or authorization.

This article examines the claims contained in the Immaculate Constellation report with precision. It separates verified elements from allegations, places the program within the broader timeline of UAP disclosure efforts, and assesses what the existence of such a program — if confirmed — would mean for government transparency and systemic risk assessment. The analysis draws directly from the congressional record, Shellenberger’s public statements, and subsequent interviews with the whistleblower, identified in 2025 as Matthew Brown.

The November 2024 Whistleblower Report

Delivery to Congress

Michael Shellenberger, founder of the Public newsletter, presented the 12-page report during the November 13, 2024 hearing. Multiple members of Congress, including Representatives Nancy Mace and Tim Burchett, acknowledged receipt of the document on the record. The report was entered into the congressional record and quickly became one of the most discussed pieces of UAP-related evidence in recent years.

Author and Sourcing

The document was authored by an individual with claimed access to classified UAP programs. In subsequent public appearances throughout 2025, the whistleblower identified himself as Matthew Brown, a former national security professional. Brown stated that he compiled the report based on information gathered during his government service and through protected channels. Shellenberger has described the sourcing as multiple individuals holding appropriate clearances.

Core Thesis of the Report

The central claim is that the Department of Defense operates a highly compartmented program, created around 2017, whose primary mission is the systematic collection, analysis, and storage of UAP-related imagery and signature data. The program allegedly serves as a “nexus” that aggregates observations from across the military and intelligence apparatus.

What Immaculate Constellation Allegedly Is

Program Classification and Structure

According to the report, Immaculate Constellation is structured as an Unacknowledged Special Access Program (USAP). These programs operate with extremely limited access and often exist outside standard congressional reporting channels. The document positions Immaculate Constellation as a “parent” or coordinating entity rather than a field collection unit.

Stated Mission

Its stated purpose is to maintain a comprehensive database of high-fidelity UAP observations, including:

• Still imagery and video from military and intelligence sensors
• Measurement and signature intelligence (radar, infrared, acoustic, and other technical data)
• Associated human intelligence reports

The program allegedly prioritizes cases that demonstrate advanced performance characteristics or transmedium behavior.

Relationship to Other UAP Efforts

The report claims Immaculate Constellation was established after the 2017 New York Times revelation of the Advanced Aerospace Threat Identification Program (AATIP). It supposedly absorbed or coordinated with elements of existing UAP-related activities while maintaining a higher level of compartmentalization.

Evidence Categories and Technical Capabilities

Imagery Intelligence (IMINT)

The report emphasizes the program’s focus on high-resolution imagery and video. It allegedly holds material showing objects with performance profiles that exceed known conventional or adversary technology.

Measurement and Signature Intelligence (MASINT)

Beyond visual data, the program reportedly collects and analyzes technical signatures — radar returns, infrared signatures, electromagnetic emissions, and acoustic data — that help characterize UAP performance and possible propulsion or sensor systems.

Human Intelligence and Raw Data

In addition to sensor data, the report references human intelligence reports from military personnel who have encountered UAP. These accounts are allegedly cross-referenced with sensor data to build more complete case files.

Documented Incidents and Case Studies

2023 F-22 Orb Encounter

One of the most specific incidents described involves an F-22 Raptor that was reportedly forced out of its patrol area by a formation of orbs in 2023. The report claims the objects demonstrated coordinated behavior that affected the aircraft’s operations.

Orange-Red Sphere and Physiological Effects

Another case involves aircrew observing an orange-red sphere descend from high altitude. Witnesses reportedly experienced a temporary sensation of unease or trance-like state before the object departed.

Transmedium Object off Kuwait

The report references a 13-minute video, allegedly discovered on a Department of Defense secure network, showing a white orb emerging from the ocean approximately 20 miles off the coast of Kuwait and ascending rapidly.

These cases are presented as examples of the type of high-quality, multi-sensor data the program allegedly maintains.

Connection to Existing UAP Programs and Disclosure Timeline

Relationship to AARO and Official Channels

The Immaculate Constellation report emerged alongside ongoing work by the All-domain Anomaly Resolution Office (AARO). The document implies that certain categories of UAP data have been routed through highly restricted channels rather than standard AARO reporting processes.

Link to Broader Disclosure Efforts

The 2024 hearing and subsequent PURSUE releases in 2026 have increased pressure for transparency. Immaculate Constellation represents one of the most detailed allegations of a parallel, highly classified track running alongside publicly acknowledged UAP efforts.

Matthew Brown’s Subsequent Statements

In 2025 interviews, Matthew Brown expanded on the report’s contents while emphasizing the importance of responsible disclosure and the protection of sources and methods.

Official Response, Verification Challenges, and Systemic Implications

Department of Defense Position

As of June 2026, the Department of Defense and AARO have not issued a formal confirmation or denial specifically addressing the existence of Immaculate Constellation by name. Official statements continue to emphasize that AARO has not found evidence of extraterrestrial technology or off-world craft in resolved cases.

Verification Challenges

Because the program is alleged to be unacknowledged, independent verification remains extremely difficult. Much of the supporting material remains classified, and the chain of custody for the 12-page report relies on the credibility of the whistleblower and the journalist who delivered it.

Systemic Risk Implications

If a program of this nature exists and operates with minimal congressional oversight, it raises significant questions about accountability, resource allocation, and the potential concentration of sensitive information within a very small circle of personnel. The report’s claims also intersect with ongoing debates about technological surprise and strategic stability.

INSIGHTS

• UAP Whistleblower Report on Immaculate Constellation – U.S. House Oversight Committee, Congressional Record, November 13, 2024 (publicly referenced 12-page document submitted by Michael Shellenberger).
• Hearing Testimony and Q&A – U.S. House Committee on Oversight and Accountability, “Unidentified Anomalous Phenomena: Exposing the Truth,” November 13, 2024.

These primary sources are crucial because they represent direct congressional engagement with the allegations rather than secondary reporting. They allow researchers and policymakers to assess the specific claims against the record of official UAP investigations conducted by AARO.
