AARO First Historical Record Report — Volume I to Congress

On March 8, 2024, the All-domain Anomaly Resolution Office (AARO), established by Congress in 2022 under the Office of the Secretary of Defense, delivered Volume I of its Historical Record Report on UAP to the Senate and House Armed Services Committees. The report represented the most comprehensive officially mandated review of US government UAP history ever conducted. AARO interviewed over 30 witnesses — government employees, military personnel, and contractors who had claimed direct knowledge of UAP programs or non-human intelligence. It reviewed hundreds of classified programs and gained access to intelligence community records spanning 1945 to 2023. Key findings of the report: (1) AARO found no verifiable evidence that the US government or private industry had recovered non-human technology or biological material. (2) Several high-profile UAP claims were traced to misidentified US classified programs. (3) The report confirmed a sustained, documented pattern of UAP detections near US nuclear weapons facilities and research sites from 1945 forward. (4) AARO acknowledged 800+ unresolved cases in its active database. (5) The report noted 'a series of concerning events involving persistent intrusions by unidentified objects in controlled airspace' near military operating areas. Volume II of the report, covering additional classified material, was delivered separately to Congress with restricted access.
