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
