State of the record

Updated 28 September 2026

The record holds 900 documents from 23 official and academic sources, with 297 added over the past two months. The period was dominated by the activity of the All-domain Anomaly Resolution Office (AARO), the US Department of Defense body: its new director presented the annual report to the Senate, singling out a subset of cases described as «truly anomalous» that require further analysis, and the Pentagon released a fifth batch of declassified files alongside a single consultation portal. In September, a congressional hearing gathered criticism from witnesses about the institutional handling of reports. In recent days, videos of cases catalogued as unresolved were also released through the Department of Defense's audiovisual service (DVIDS), among them recordings from the Pacific Ocean (2019) and the Gulf of Oman (2021). Programmatic access to Record Group 615 of the US national archive remains pending credentials.
