Overview
The October 2023 consolidated annual report describes an investigation learning to distinguish a growing intake from a growing number of unusual events. AARO received 291 reports for the reporting exercise, including 17 about earlier years. Civil aviation supplied observations from places outside the military’s usual collection areas, while most cases still lacked the information needed for identification.
Published jointly by the Department of Defense and the Office of the Director of National Intelligence (ODNI), this is a different document from the January 2023 annual report. Its observation window runs from 31 August 2022 to 30 April 2023. Later institutional updates and a worked case-resolution example extend beyond that cut-off.
Chronology

The reporting population
Of the 291 additions, 274 concerned events within the observation window and 17 concerned events from 2019–2022. AARO’s cumulative holdings reached 801 reports by 30 April 2023. These are intake and catalogue figures: a later submission enters the year in which it is received even when the reported encounter occurred earlier. Comparing annual totals without keeping those dates apart would exaggerate changes in observed activity. Report, printed p. 5.
The office assigned 290 additions to the air domain and one to the maritime domain. It recorded no space or transmedium additions in this group. Those categories describe what reached AARO through its reporting partners. They cannot determine how often unidentified observations occurred in environments where the office had little collection coverage.
What civilian reporting changed
AARO said it had received more than 100 FAA incident reports. Most described lights without a definite shape, at widely varying estimated altitudes. The report says this civilian group displayed no anomalous characteristics and included no unsafe approach to the observing aircraft. It contrasts that intake with some military reports containing performance characteristics that required further examination. The two descriptions concern different reporting groups. Report, printed p. 8.
Commercial pilots broadened the geographical coverage inside and around the United States. That improvement also made the overall catalogue more U.S.-centred relative to the rest of the world. A denser map of reports therefore reflects an expanded reporting network as well as whatever people encountered.
Figure 1 leaves the morphology unreported for 53 per cent of its plotted reports. Rounded or spherical descriptions account for 25 per cent. The large unreported category matters when these diagrams are used to discuss a characteristic UAP shape: the diagram describes recorded descriptions, including a substantial failure to record one.
Calibration and a worked resolution
AARO described a calibration campaign using known balloons, uncrewed aircraft and natural phenomena. The resulting measurements were intended for models, operator training and analysis algorithms. Testing familiar objects under relevant viewing conditions would give analysts comparisons for shapes and movements produced by the sensor itself. The report outlines that programme; it does not publish its complete calibration dataset. Report, printed p. 9.
The appendix supplies a more concrete example. Military personnel had reported five apparently equidistant lights in western U.S. military airspace in 2021. The 8 May 2023 resolution attributes them to commercial aircraft travelling on established corridors, in some instances as far as 300 nautical miles from the observing platform. AARO reports agreement between its intelligence and scientific partners after positional, air-traffic and boresight analysis. Resolution example, printed pp. 12–13.
Distance changes the interpretation of the lights. Aircraft far beyond the restricted area could appear aligned in the sensor’s viewing direction without entering that airspace. The public example identifies the geometric comparison and the attributed outcome, but provides too little underlying tracking information to repeat the whole reconstruction. This 2021 aircraft case should be kept separate from later western U.S. publications concerning countermeasure flares.
Evidence assessment
FAA submissions broaden the catalogue beyond its earlier military emphasis, while the aircraft example shows how viewing geometry changes an apparent identification problem. The report consequently gives readers two concrete reasons to distinguish reporting coverage from the character of the observed objects.
The aggregate tables offer less control over the residual cases. They do not supply a case-by-case set of measurements or a common test applied to every entry. The report’s judgement that many unresolved observations would become ordinary identifications with better data is an institutional expectation. Its worked example supports that route to resolution in one case; the remaining catalogue requires its own comparisons.
