What It Is
The Pentagon’s All-domain Anomaly Resolution Office. Established under the Department of Defense (now Department of War) to investigate UAP reports across air, sea, space, and underwater domains.
Role in PURSUE
Provides technical case analysis for declassified files. One of six participating agencies in the May 2026 release.
The 2024 Historical Record Report (Most Useful Anchor)
AARO’s 2024 historical review of US UFO/UAP cases reported “no evidence of extraterrestrial origin for the historical UFO and UAP cases reviewed.”
This finding is the baseline against which any PURSUE-released case is measured. As of May 8, 2026, the new tranche does not contain a case that has overturned this baseline.
The “Unresolved” Frame
Per AARO methodology and current PURSUE language: “unresolved means the government has not made a definitive determination.” Lack of data, not presence of anomaly. This distinction is doing most of the actual evidentiary work in current coverage.

Open Questions
- Does AARO update the 2024 historical record after the Apollo 17 re-analysis?
- Will subsequent PURSUE tranches publish AARO case files with full sensor metadata, or stay at the “unresolved” tier with redacted context?
