Report on the ODNI UAP Reports (2021–2023)

Between 2021 and 2023, the Office of the Director of National Intelligence (ODNI), in partnership first with the Navy’s UAP Task Force and later the Department of Defense’s All-domain Anomaly Resolution Office (AARO), released three landmark unclassified reports on UAP. These represent the most systematic U.S. government data disclosures since 2004.

The first, in June 2021, reviewed 144 cases, most from 2019–2021, with 80 multi-sensor observations and 18 incidents showing unusual movement, such as hovering against wind or abrupt maneuvers. Eleven were aviation near misses. Only one case was definitively resolved as a balloon.

By August 2022, the total rose to 510 reports, thanks to expanded intake and destigmatization. Of 366 newly identified, 195 were initially categorized as drones, balloons, or clutter, while 171 remained uncharacterized. No confirmed collisions or health effects were recorded.

The FY2023 report brought the total to 801 cases. Civil aviation inputs—especially from the FAA added over 100 reports, mostly of lights without anomalous characteristics. Shape data showed spheres as the most common, but over half lacked description. No transmedium or space-domain UAP were noted.

Together, these reports highlight growing datasets, improved transparency, and persistent unexplained cases demanding deeper, multi-sensor study. (Director of National Intelligence, AARO)

Key points

  • Reporting window covered: November 2004–April 30, 2023 (with annual reporting cycles starting in 2021). (Director of National Intelligence, AARO)
  • Total UAP reports cataloged by AARO as of April 30, 2023: 801, including new cases in FY2023 and previously uncounted earlier cases. AARO
  • Earlier baselines:
    • 144 reports in the June 2021 preliminary assessment (majority from 2019–2021). 80 of these involved multi-sensor observation; 18 incidents (21 reports) described unusual movement or “advanced” flight characteristics; 11 documented near misses affecting aviator safety. Director of National Intelligence
    • By August 30, 2022, ODNI tallied 510 total reports; of the 366 newly identified since March 2021, initial triage judged 26 as UAS/drone-like, 163 balloon/balloon-like, 6 airborne clutter, 171 remained uncharacterized/unattributed. 
  • FY2023 morphology snapshot (subset): “Orb/round/sphere” (~25%) led the reported shapes among cases with shapes recorded; over half lacked shape reporting. No transmedium or space-domain UAP were reported in this period. AARO
  • Safety and health: No documented collisions or confirmed adverse health effects reported in the unclassified releases (while multiple near-misses were logged historically). (AARO, Director of National Intelligence)

How we got here: Legislative and organizational context

Congress directed standardized annual (and quarterly, classified) reporting on UAP beginning with the Intelligence Authorization Act and the FY2022 National Defense Authorization Act (NDAA). ODNI’s June 25, 2021 preliminary assessment was compiled by the UAPTF with contributions across the Intelligence Community (IC). In July 2022, DoD consolidated responsibilities in a new office, AARO. with a broader “all-domain” charter (air, sea, and potential transmedium) and an explicit mandate to standardize collection, analytics, and reporting across DoD and IC, in coordination with ODNI’s National Intelligence Manager. Director of National Intelligence

The 2022 ODNI Annual Report (released Jan 12, 2023) was the first to integrate AARO’s processes, establish a combined database, and present a triage-style “initial characterization” for new cases. The FY2023 consolidated report (released October 2023) is the first joint DoD–ODNI report authored with AARO in the lead, and it expands trend analysis, including shape/altitude distributions and a notable influx of civil/FAA reports. AARO

2021 Preliminary Assessment:

Scope & data quality. The 2021 document examined 144 USG-sourced UAP reports spanning 2004–March 2021, noting limited, inconsistent historical reporting until the Navy’s 2019 mechanism and the USAF’s 2020 adoption. Nevertheless, ODNI emphasizes that “most of the UAP reported probably do represent physical objects,” citing corroboration across multiple sensors (radar, IR, EO, weapon seekers, and visual observation). 

Key figures (unclassified):

  • 144 total reports; 80 multi-sensor; 11 near-miss safety incidents
  • 18 incidents (21 reports) highlighted apparent advanced technology: stationary against winds aloft, movement against the wind, abrupt maneuvers, high speed without discernible propulsion, and occasional RF energy association. ODNI cautioned about potential sensor error/spoofing and called for rigorous technical analysis. 

Initial explanatory framework (5 categories). ODNI proposed: airborne clutter, natural atmospheric phenomena, USG/U.S. industry developmental programs, foreign adversary systems, and Other. No broad attributions were made; only one case was definitively resolved as a deflating balloon. The report called for standardized reporting, consolidated databases, and AI/ML analytics to cluster and compare cases. 

2022 ODNI Annual Report: Growth to 510, creation of AARO, and first triage

Database growth. By Aug 30, 2022, ODNI/AARO counted 510 UAP reports. That total combined the 2021 baseline with 247 newly reported events (post-cutoff) plus 119 “found” or late-reported earlier cases. 

Initial characterization of the 366 new reports. AARO’s first-pass analytics judged more than half to exhibit “unremarkable” characteristics consistent with ordinary sources:

  • 26: UAS/drone-like
  • 163: balloon/balloon-like
  • 6: airborne clutter (e.g., birds, debris)
  • 171: uncharacterized/unattributed after initial triage (some displaying unusual flight characteristics). 

Safety & health. ODNI notes no reported collisions or confirmed adverse health effects in released data to that point, while still stressing UAP as a flight-safety hazard and potential intelligence-collection threat if linked to adversaries. The report emphasizes continued destigmatization as a driver for increased reporting. 

Institutional shift. With AARO established in July 2022, ODNI framed a whole-of-government pathway: synchronized collection, common analytic standards, and more robust case adjudication across DoD, IC, FAA, NASA, NOAA, DOE, and others. 

Volume and time frame. The FY2023 report covers Aug 31, 2022–Apr 30, 2023, adding 291 reports (274 from the period, 17 legacy additions). Cumulative total: 801 UAP reports in AARO holdings as of April 30, 2023. 290 occurred in the air domain, 1 maritime; none were transmedium or space-domain in this cycle. AARO

Morphology and reporting trends.

  • Shapes (among those that reported shapes): orb/round/sphere25%, with smaller fractions for disk, oval, triangle, cylinder, rectangle, and irregular forms; >50% of cases did not report a shape.
  • Lights: ~21% reported lights; ~79% no lights.
  • FAA: 100+ incident reports flowed from FAA, skewed strongly toward unidentified lights without shape, at altitudes from <5,000 ft to ~60,000 ft. These FAA cases were not assessed as exhibiting anomalous characteristics or unsafe proximities. AARO

Safety & health reaffirmed. As with 2022, AARO reported no confirmed adverse health effects; safety-of-flight concerns persist largely because unknowns in controlled airspace require deconfliction and can disrupt operations. AARO

Methodological notes. AARO underscored persistent data-quality gaps (radar/EO/IR capture issues, IR flare, parallax, and other sensor or perceptual artifacts). It reported that only a very small percentage of cases display “interesting signatures” (e.g., apparent high speed or unusual maneuverability), and that improved data fidelity is likely to resolve many unidentified cases to ordinary phenomena. That said, AARO highlighted new sensor calibration campaigns (e.g., modeling known objects, balloons, UAS, natural phenomena) to improve future discrimination. AARO

Cross-year comparison: What actually changed

  1. Report volume and breadth increased sharply. From 144 (2019–2021 heavy) to 510 (by Aug 2022) to 801 (by Apr 30, 2023). The driver is not necessarily “more UAP in the sky,” but better destigmatized reporting, more active collection, and inclusion of previously uncounted events. The FY2023 report also shows the geographic bias beginning to shift as civil aviation reports ramp up. AARO
  2. Organizational maturation. The 2021 assessment was essentially a scoping document. The 2022 report shows AARO stood up and began applying a repeatable triage. The FY2023 cycle deepened trend analysis and case-closure mechanics while building out S&T and calibration tooling. AARO
  3. Safety through transparency. The thread across all three documents: UAP are a flight-safety issue. The 2021 near-miss count (11), plus recurring range fouler disruptions, underscores operational risk, even when objects are ultimately mundane. The absence of confirmed health effects and collisions does not eliminate risk; it spotlights the urgency of better identification and deconfliction. (Director of National Intelligence, AARO)
  4. Unresolved core remains. Even after removing balloon/UAS/clutter-like cases in 2022, 171 new cases remained uncharacterized; FY2023 notes only a small fraction show “interesting signatures,” but it does not zero them out; those still demand rigorous, multi-sensor, multi-agency study.  AARO

What the data says

What it says (unclassified):

  • A growing corpus (801 by April 2023) exists across DoD/IC channels, enriched by FAA inputs.
  • A substantial share of cases can be triaged to plausibly mundane sources; some remain uncharacterized even after initial review.
  • A consistent minority of reports claim features like abrupt maneuvers, stationary behavior against wind, or no obvious propulsion, with a few reporting RF associations without definitive prosaic attribution (yet). Director of National Intelligence

What it doesn’t (yet) say:

  • Causation for the unresolved subset is not established in the unclassified record. The 2021 framework explicitly included a catch-all “Other” category pending future science. The 2023 report stresses that better data tends to resolve cases, but it leaves open the possibility that some interesting signatures could persist under deeper scrutiny. (Director of National Intelligence, AARO)

Data and bias: reading the numbers critically

Three persistent biases shape the dataset:

  1. Collection bias to restricted airspace. Military ranges and warning areas are dense with sensors and observers, raising detection rates and reports, but also increasing range fouler incidents (which are promptly logged). As civil reporting scales via FAA, the map should diversify. Director of National Intelligence AARO
  2. Sensor & perceptual artifacts. IR flare, parallax, glare, compression, and angle-of-attack can mimic non-ballistic motion or odd accelerations. The 2023 report explicitly flags these issues and describes calibration campaigns to benchmark known targets for algorithmic discrimination. AARO
  3. Stigma & underreporting (now easing). ODNI credits destigmatization efforts with rising report volume, especially important for commercial pilots who previously lacked clear reporting avenues.

Safety and national-security implications

  • Aviation safety: Unknowns inside controlled or restricted airspace cause mission aborts, deconfliction maneuvers, and degraded training/test efficiency. Even if many cases resolve to balloons, UAS, or clutter, timely identification is essential to avoid near misses and protect crews and passengers. Director of National Intelligence
  • Counterintelligence: Some portion could be adversary collection platforms probing sensors and TTPs. That possibility is a standing driver for rapid attribution, cross-domain sensor fusion, and intel deconfliction. Director of National Intelligence
  • Scientific opportunity: The unresolved remainder includes outlier kinematics reported by trained observers. Regardless of ultimate explanations, a disciplined, multi-sensor approach can yield advances in tracking, sensor calibration, and data fusion that benefit air traffic safety and space/maritime domain awareness. AARO

Recommendations

For ODNI/AARO and mission partners

  1. Publish a standardized UAP data schema (unclassified version) aligned with operational needs: time-sync’d multi-sensor inputs (radar/EO/IR/RF), platform metadata (altitude, speed, heading), atmospherics, and observer qualification tags. Provide machine-readable summaries upon case closure. (This extends the reports’ call for standardized collection and analytics.) AARO
  2. Expand calibration campaigns: Continue measuring balloons (various materials/diameters), UAS (fixed/rotor), atmospheric/astronomical phenomena, and birds across sensor modalities, publishing signature libraries and simulation models for training and algorithm development. AARO
  3. Accelerate civil-aviation integration: Formalize FAA intake with a structured, optional “UAP supplemental” to existing incident reporting, capturing raw sensor exports (where available) and crew debriefs, while protecting PII and commercial sensitivities. (The 2023 report shows this is already moving; scale it.) AARO
  4. Case-closure transparency tiers: For each case, publish a closure tier (Resolved, Explained; Resolved, Insufficient Data; Open, Under Analysis; Open, High-Interest) with a minimal unclassified synopsis that includes what data were not available (e.g., no radar, single-sensor, no RF, no weather logs).
  5. Adversary deconfliction cell: Maintain a standing, rapid deconfliction channel between AARO, IC, and service intel centers to quickly rule in/out known U.S. programs and known foreign platforms, reducing long-lived ambiguity. (FY2023 mentions deconfliction; this makes it an always-on function.) AARO
  6. Independent technical review panels: Convene rotating panels (academia, national labs, industry) with read-ins as needed to replicate analyses (especially of the “interesting signature” subset). This follows the reports’ call for rigorous, peer-reviewed methods. (Director of National Intelligence, AARO)

For Congress

  1. Sustain and sharpen mandates: Continue requiring annual public summaries and standardized metrics (e.g., proportion multi-sensor; time-to-closure; % resolved by category; % requiring additional collection). Strongly encourage publication of de-identified datasets for independent analysis.
  2. Resource the data layer: Fund shared repositories that can securely handle multi-INT UAP data (classified/unclassified partitions), with audit trails and FOIA-ready redaction tooling.

For researchers and civil society

  1. Adopt interoperable metadata: Align civilian UAP research (observatory, academic, citizen-science networks) to compatible schemas so that well-documented non-DoD incidents can be compared or triaged alongside government cases.
  2. Focus on replicable pipelines: Prioritize open algorithms for motion analysis, parallax disambiguation, and IR artifact detection that can be tested on calibration sets (balloon/UAS libraries) and then applied to the “interesting” subset.

Implications for policy, science, and culture

  • Policy: The U.S. has moved from ad hoc handling to a repeatable, reportable process with AARO. That shift reduces stigma, improves safety, and builds a cumulative dataset that policymakers can monitor via year-over-year metrics rather than sensational incidents.  AARO
  • Science: Calibration against known targets, publication of signature libraries, and structured case-closure data would enable reproducible science, allowing external teams to stress-test claims and algorithms without exposing sensitive sources/methods. AARO
  • Public understanding: The reports repeatedly state that many cases resolve to ordinary sources when data are sufficient. At the same time, a non-zero remainder persists. Mature discourse means holding both realities: most reports may be explainable and there may remain anomalies that need better data, not dismissal.  AARO

Frequently asked clarifications (based on the reports)

  • Do the reports claim exotic origins? No. They document unresolved cases and interesting signatures but do not assert extraordinary causes. They also emphasize how better data tends to reduce the “unknown” pool. AARO
  • Are there verified collisions or health impacts? None confirmed in the unclassified releases (to 2023). Near-misses were documented historically (11 in the 2021 set). Director of National Intelligence
  • Is “transmedium” in the official data? The FY2023 report explicitly states no transmedium or space-domain UAP were submitted in that period. AARO

Speculation labels 

Hypothesis: A small subset of UAP in the unresolved pool reflects non-adversarial, non-prosaic phenomena with performance characteristics outside presently cataloged aerospace systems.
Rationale: The 2021 assessment documents 18 incidents (21 reports) with unusual kinematics and occasional RF association; 2022 retains 171 uncharacterized cases (after removing obvious balloons/UAS/clutter); 2023 flags only a small percentage with “interesting signatures” but does not dismiss them. These do not establish extraordinary origins; they do warrant high-grade data capture and independent replication. (Director of National Intelligence, AARO)

Witness Interpretation: Pilot reports emphasizing abrupt accelerations or stationary behavior against winds may partly reflect sensor/perceptual effects, but not necessarily in every instance.
Rationale: AARO documents parallax/IR flare and other artifacts; however, some cases include multi-sensor corroboration that resists trivial explanations, justifying case-by-case technical adjudication. Director of National Intelligence AARO

Researcher Opinion: Prioritizing multi-sensor, high-fidelity capture on a standing watch (especially in range-adjacent corridors and high-altitude lanes) offers the best chance to convert “interesting signatures” from anecdote into adjudicated physics.
Rationale: This is the explicit direction AARO is moving via calibration campaigns and sensor placement guidance; scaling it should quickly separate mundane from non-mundane. AARO
