Annual Report on Unidentified Anomalous Phenomena (UAP / UFO) – Oct. 2023

“Unidentified Anomalous Phenomenon (UAP): Sources of anomalous detections in a number of area (i.e., airborne, seaborne, spaceborne, and/or transmedium) that aren’t but attributable to identified actors and that exhibit behaviors that aren’t readily understood by sensors or observers. ‘Anomalous detections’ embrace however aren’t restricted to phenomena that exhibit obvious capabilities or materials that exceed identified efficiency envelopes. A UAP might include a number of unidentified anomalous objects and should persist over an prolonged time period.”

I. EXECUTIVE SUMMARY

Authorization Act (NDAA) for Fiscal 12 months (FY) 2022, Part 1683 (h), as amended by Part 6802(okay) of the FY 2023 NDAA (as codified at 50 U.S.C. § 3373).

The report covers unidentified anomalous phenomena (UAP) reviews from 31 August 2022 to 30 April 2023, and all UAP reviews from any earlier time durations that weren’t included in an earlier report. The All-domain Anomaly Decision Workplace (AARO) obtained a complete of 291 UAP reviews throughout this era, consisting of 274 that occurred throughout this interval and one other 17 that occurred throughout earlier reporting durations from 2019-2022, however had not been conveyed inprevious submissions.

Reporting from this era continues to depict a powerful however shifting assortment bias. Most reviews nonetheless mirror a bias in the direction of restricted navy airspace, a results of reporting from navy personnel and sensors current in such areas. This bias has been lessened by reporting from business pilots exhibiting a extra numerous geographic distribution of UAP sightings throughout the USA. Nonetheless, these reviews principally cowl observations over U.S. airspace and littoral waters, and due to this fact, as these reviews proceed to return in, a U.S.-centric assortment bias will develop considerably relative to the remainder of the world.

Throughout the reporting interval, AARO obtained no reviews indicating UAP sightings have
been related with any adversarial well being results. Nonetheless, many reviews from navy witnesses
do current potential security of flight considerations, and there are some instances the place reported UAP have
doubtlessly exhibited one or extra regarding efficiency traits such as high-speed
journey or uncommon maneuverability. AARO has de-conflicted these instances with potential U.S.
applications and continues to work carefully with its DoD and Intelligence Group (IC) mission
companions to determine and attribute any objects discovered in these instances. Moreover, AARO
continues to examine and analysis all instances in its holdings.

Whereas the mere presence of UAP in the airspace represents a potential hazard to flight
security, none of these reviews counsel the UAP maneuvered to an unsafe proximity to civil or
navy plane, positioned themselves in flight paths, or in any other case posed a direct risk to the
flight security of the observing plane. Though none of these UAP reviews have been positively
attributed to international actions, these instances proceed to be investigated.

AARQO continues to make progress receiving, standardizing, analyzing, and resolving
reviews of UAP; working with navy and technical companions to enhance sensor placement and
calibration to higher accumulate towards UAP; to elevate the high quality of reporting; and to present danger
discount for improved area consciousness.

Whereas this progress is facilitating assortment and evaluation of the UAP drawback set, the
continued quantity and unidentified nature of most UAP is a direct consequence of gaps in
area consciousness. These gaps are the direct outcome of inadequate information secured by radar, electro-
optical (EO)/infrared (IR) sensors; the presence of sensor artifacts, such as IR flare; and optical
results, such as parallax, that can trigger observational misperceptions. Primarily based on the skill to
resolve instances to date, with an enhance in the high quality of information secured, the unidentified and
purported anomalous nature of most UAP will doubtless resolve to unusual phenomena and
considerably cut back the quantity of UAP case submissions.
