Immaculate Constellation

Immaculate Constellation is an alleged unacknowledged Special Access Program (USAP) within the U.S. defense and intelligence apparatus, focused on UAP surveillance and data collection.

Origins

According to matthew-brown and prior reporting, the program was established after lue-elizondo publicly exposed aatip through a December 2017 New York Times article. The DoD allegedly created Immaculate Constellation as a successor or parallel effort to continue UAP data collection under tighter secrecy.

Mission

The program’s core mission was a consolidation effort — gathering UAP data from across military and intelligence collection platforms:

  • Both “tasked” (intentionally directed) and “untasked” (incidental) captures
  • Served as a central parent USAP aggregating observations
  • Distributed relevant intelligence to authorized officials
  • Database includes imagery from infrared sensors, FLIR, full-motion video, and still photography

Discovery

matthew-brown accidentally encountered the program while managing files on a Pentagon server, finding a classified 2018 Schriever War Game document containing:

  • References to Russian naval awareness of UAP near the Kamchatka Peninsula
  • Global UAP imagery from multiple sensor platforms
  • Evidence of cross-national UAP tracking

Official Denial

The Department of Defense has denied the program’s existence. Spokesperson Sue Gough: “The Department of Defense has no record, present or historical, of any type of SAP called ‘IMMACULATE CONSTELLATION.‘”

However, the ODNI released a FOIA-related document (DF-2025-00021) pertaining to the program, and it was referenced in documents for a November 2024 House hearing.

Relationship to Other Programs

  • Successor/parallel to aatip
  • Distinct from but related to crash-retrieval-programs (focuses on surveillance rather than material recovery)
  • Exists alongside kona-blue and other alleged UAP programs in a larger ecosystem of classified activities
